New feature Patch [#33445] - Experimental Cycles Hair Rendering (CPU only) This patch allows hair data to be exported to cycles and introduces a new line segment primitive to render with. The UI appears under the particle tab and there is a new hair info node available. It is only available under the experimental feature set and for cpu rendering.

#include "device.h"
#include "blender_sync.h"
Cycles: Initialize "headless" flags on engine initialization This flag is global for all the sessions and never changes. so it doesn't really make sense to pass it around to all sessions and synchronization routines. Switched to a static member of BlenderSession now, but it's probably more logical to introduce some sort of BlenderGlobals. Doesn't currently worth a hassle for a single boolean flag tho.

Better fix for #36935 and 36316: * 32 bit GCC builds now have the SSE BVH optimizations turned off, but still compile with SSE flags for better performance. * White color when rendering on Windows seems to have been unrelated to SSE, rather it was a graphics driver not supporting half float textures, added a check for that now.

#include "util_opengl.h"
Cycles: Make animated seed a builtin feature. For animations, you often want an animated render seed (noise pattern). This could be done by e.g. setting a driver on the seed value. Now it's a little checkbox, that can be enabled. The animated seed is based on the current Blender frame and the seed value itself. Simply enabling it, will already result in an animated seed (different on each Blender frame), but it can be randomized further by setting a different seed value. Disabled per default, so no backward compatibility break. Differential Revision: https://developer.blender.org/D1285

Cycles: Support texture coordinate from another object This is the same as blender internal's texture mapping from another object, so this way it's possible to control texture space of one object by another. Quite straightforward change apart from the workaround for the stupidness of the dependency graph. Now shader has flag telling that it depends on object transform. This is the simplest way to know which shaders needs to be tagged for update when object changes. This might give some false-positive tags now but reducing them should not be priority for Cycles and rather be a priority to bring new dependency graph. Also GLSL preview does not support using other object for mapping. This is actually correct for BI shading as well and to be addressed as a part of general GLSL viewport improvements since it's not really clear how to support this in GLSL.

Fix for #32184 and redesign of particle storage in Cycles. The particle data used by the Particle Info node was stored in cycles as a list in each object. This is a problem when the particle emitter mesh is hidden: Objects in cycles are only intended as instances of renderable meshes, so when hiding the emitter mesh the particle data doesn't get stored either. Also the particle data can potentially be copied to multiple instances of the same object, which is a waste of texture space. The solution in this patch is to make a completely separate list of particle systems in the Cycles scene data. This way the particle data can be generated even when the emitter object itself is not visible.

Cycles: Free unused image buffers when rendering with locked interface It is still possible to free a bit more memory by detecting buildin images which are not used by shaders, but that's not going to improve memory usage that much to bother about this now. Such change brings peak memory usage from 4.1GB to 3.4GB when rendering 01_01_01_D layout scene from the Gooseberry project. Mainly because of freeing memory used by rather huge environment map in the viewport.

Cycles Volume Render: scattering support. This is done by adding a Volume Scatter node. In many cases you will want to add together a Volume Absorption and Volume Scatter node with the same color and density to get the expected results. This should work with branched path tracing, mixing closures, overlapping volumes, etc. However there's still various optimizations needed for sampling. The main missing thing from the volume branch is the equiangular sampling for homogeneous volumes. The heterogeneous scattering code was arranged such that we can use a single stratified random number for distance sampling, which gives less noise than pseudo random numbers for each step. For volumes where the color is textured there still seems to be something off, needs to be investigated.

Cycles Volume Render: heterogeneous (textured) volumes support. Volumes can now have textured colors and density. There is a Volume Sampling panel in the Render properties with these settings: * Step size: distance between volume shader samples when rendering the volume. Lower values give more accurate and detailed results but also increased render time. * Max steps: maximum number of steps through the volume before giving up, to protect from extremely long render times with big objects or small step sizes. This is much more compute intensive than homogeneous volume, so when you are not using a texture you should enable the Homogeneous Volume option in the material or world for faster rendering. One important missing feature is that Generated texture coordinates are not yet working in volumes, and they are the default coordinates for nearly all texture nodes. So until that works you need to plug in object texture coordinates or a world space position. This is work by "storm", Stuart Broadfoot, Thomas Dinges and myself.

Cycles: merging features from tomato branch. === BVH build time optimizations === * BVH building was multithreaded. Not all building is multithreaded, packing and the initial bounding/splitting is still single threaded, but recursive splitting is, which was the main bottleneck. * Object splitting now uses binning rather than sorting of all elements, using code from the Embree raytracer from Intel. http://software.intel.com/en-us/articles/embree-photo-realistic-ray-tracing-kernels/ * Other small changes to avoid allocations, pack memory more tightly, avoid some unnecessary operations, ... These optimizations do not work yet when Spatial Splits are enabled, for that more work is needed. There's also other optimizations still needed, in particular for the case of many low poly objects, the packing step and node memory allocation. BVH raytracing time should remain about the same, but BVH build time should be significantly reduced, test here show speedup of about 5x to 10x on a dual core and 5x to 25x on an 8-core machine, depending on the scene. === Threads === Centralized task scheduler for multithreading, which is basically the CPU device threading code wrapped into something reusable. Basic idea is that there is a single TaskScheduler that keeps a pool of threads, one for each core. Other places in the code can then create a TaskPool that they can drop Tasks in to be executed by the scheduler, and wait for them to complete or cancel them early. === Normal ==== Added a Normal output to the texture coordinate node. This currently gives the object space normal, which is the same under object animation. In the future this might become a "generated" normal so it's also stable for deforming objects, but for now it's already useful for non-deforming objects. === Render Layers === Per render layer Samples control, leaving it to 0 will use the common scene setting. Environment pass will now render environment even if film is set to transparent. Exclude Layers" added. Scene layers (all object that influence the render, directly or indirectly) are shared between all render layers. However sometimes it's useful to leave out some object influence for a particular render layer. That's what this option allows you to do. === Filter Glossy === When using a value higher than 0.0, this will blur glossy reflections after blurry bounces, to reduce noise at the cost of accuracy. 1.0 is a good starting value to tweak. Some light paths have a low probability of being found while contributing much light to the pixel. As a result these light paths will be found in some pixels and not in others, causing fireflies. An example of such a difficult path might be a small light that is causing a small specular highlight on a sharp glossy material, which we are seeing through a rough glossy material. With path tracing it is difficult to find the specular highlight, but if we increase the roughness on the material the highlight gets bigger and softer, and so easier to find. Often this blurring will be hardly noticeable, because we are seeing it through a blurry material anyway, but there are also cases where this will lead to a loss of detail in lighting.

Motion vector export from Blender tries to avoid computing derived meshes when the mesh does not have a deforming modifier, and it also won't store motion vectors for every vertex if only the object or camera is moving.

Cycles: Add optional probabilistic termination of light samples based on their expected contribution In scenes with many lights, some of them might have a very small contribution to some pixels, but the shadow rays are traced anyways. To avoid that, this patch adds probabilistic termination to light samples - if the contribution before checking for shadowing is below a user-defined threshold, the sample will be discarded with probability (1 - (contribution / threshold)) and otherwise kept, but weighted more to remain unbiased. This is the same approach that's also used in path termination based on length. Note that the rendering remains unbiased with this option, it just adds a bit of noise - but if the setting is used moderately, the speedup gained easily outweighs the additional noise.

integrator->light_sampling_threshold = get_float(cscene, "light_sampling_threshold");
Cycles: first step for implementation of non-progressive sampler that handles direct and indirect lighting differently. Rather than picking one light for each point on the path, it now loops over all lights for direct lighting. For indirect lighting it still picks a random light each time. It gives control over the number of AA samples, and the number of Diffuse, Glossy, Transmission, AO, Mesh Light, Background and Lamp samples for each AA sample. This helps tuning render performance/noise and tends to give less noise for renders dominated by direct lighting. This sampling mode only works on the CPU, and still needs proper tile rendering to show progress (will follow tommorrow or so), because each AA sample can be quite slow now and so the delay between each update wil be too long.

Cycles: experimental correlated multi-jittered sampling pattern that can be used instead of sobol. So far one doesn't seem to be consistently better or worse than the other for the same number of samples but more testing is needed. The random number generator itself is slower than sobol for most number of samples, except 16, 64, 256, .. because they can be computed faster. This can probably be optimized, but we can do that when/if this actually turns out to be useful. Paper this implementation is based on: http://graphics.pixar.com/library/MultiJitteredSampling/ Also includes some refactoring of RNG code, fixing a Sobol correlation issue with the first BSDF and < 16 samples, skipping some unneeded RNG calls and using a simpler unit square to unit disk function.

Cleanup: remove Cycles layer bits checking in the kernel. At some point the idea was that we could have an optimization where we could render multiple render layers without re-exporting the scene, by just updating the layer bits. We are not doing this now and in practice with the available render layer control like exclude layers it's not always possible anyway. This makes it easier to support an arbitrary number of layers in the future (hopefully this summer), and frees up some useful bits in the kernel.

Cycles: merging features from tomato branch. === BVH build time optimizations === * BVH building was multithreaded. Not all building is multithreaded, packing and the initial bounding/splitting is still single threaded, but recursive splitting is, which was the main bottleneck. * Object splitting now uses binning rather than sorting of all elements, using code from the Embree raytracer from Intel. http://software.intel.com/en-us/articles/embree-photo-realistic-ray-tracing-kernels/ * Other small changes to avoid allocations, pack memory more tightly, avoid some unnecessary operations, ... These optimizations do not work yet when Spatial Splits are enabled, for that more work is needed. There's also other optimizations still needed, in particular for the case of many low poly objects, the packing step and node memory allocation. BVH raytracing time should remain about the same, but BVH build time should be significantly reduced, test here show speedup of about 5x to 10x on a dual core and 5x to 25x on an 8-core machine, depending on the scene. === Threads === Centralized task scheduler for multithreading, which is basically the CPU device threading code wrapped into something reusable. Basic idea is that there is a single TaskScheduler that keeps a pool of threads, one for each core. Other places in the code can then create a TaskPool that they can drop Tasks in to be executed by the scheduler, and wait for them to complete or cancel them early. === Normal ==== Added a Normal output to the texture coordinate node. This currently gives the object space normal, which is the same under object animation. In the future this might become a "generated" normal so it's also stable for deforming objects, but for now it's already useful for non-deforming objects. === Render Layers === Per render layer Samples control, leaving it to 0 will use the common scene setting. Environment pass will now render environment even if film is set to transparent. Exclude Layers" added. Scene layers (all object that influence the render, directly or indirectly) are shared between all render layers. However sometimes it's useful to leave out some object influence for a particular render layer. That's what this option allows you to do. === Filter Glossy === When using a value higher than 0.0, this will blur glossy reflections after blurry bounces, to reduce noise at the cost of accuracy. 1.0 is a good starting value to tweak. Some light paths have a low probability of being found while contributing much light to the pixel. As a result these light paths will be found in some pixels and not in others, causing fireflies. An example of such a difficult path might be a small light that is causing a small specular highlight on a sharp glossy material, which we are seeing through a rough glossy material. With path tracing it is difficult to find the specular highlight, but if we increase the roughness on the material the highlight gets bigger and softer, and so easier to find. Often this blurring will be hardly noticeable, because we are seeing it through a blurry material anyway, but there are also cases where this will lead to a loss of detail in lighting.

Cycles: Experiment with making previews more interactive There were two major problems with the interactivity of material previews: - Beckmann tables were re-generated on every material tweak. This is because preview scene is not set to be persistent, so re-triggering the render leads to the full scene re-sync. - Images could take rather noticeable time to load with OIIO from the disk on every tweak. This patch addressed this two issues in the following way: - Beckmann tables are now static on CPU memory. They're couple of hundred kilobytes only, so wouldn't expect this to be an issue. And they're needed for almost every render anyway. This actually also makes blackbody table to be static, but it's even smaller than beckmann table. Not totally happy with this approach, but others seems to complicate things quite a bit with all this render engine life time and so.. - For preview rendering all images are considered to be built-in. This means instead of OIIO which re-loads images on every re-render they're coming from ImBuf cache which is fully manageable from blender side and unused images gets freed later. This would make it impossible to have mipmapping with OSL for now, but we'll be working on that later anyway and don't think mipmaps are really so crucial for the material preview. This seems to be a better alternative to making preview scene persistent, because of much optimal memory control from blender side.

There'll be no simple solution to that apart from defining explicit mapping from RNA value to Cycles one.

Cycles: Add option to disable new Hair BVH While it's an extra option added to the interface which might not be fully obvious for artists, it allows to save up to 20% of memory in hairy scenes. This is high enough memory saver in my opinion which might become handy for some production files where it's more important to make scene to fit into memory rather than trying to use more optimal BVH structure but go into swap or crash.

params.persistent_data = false;
Cycles: persistent images option This option enables keeping loaded images in the memory in-between of rendering. Implemented by keeping render engine alive for until Render structure is being freed. Cycles will free all data when render finishes, optionally keeping image manager untouched. All shaders, meshes, objects will be re-allocated next time rendering happens. Cycles cession and scene will be re-created from scratch if render/ scene parameters were changed. This will also allow to keep compiled OSL shaders in memory without need to re-compile them again. P.S. Performance panel could be cleaned up a bit, not so much happy with it's vertical alignment currently but not sure how to make it look better. P.P.S. Currently the only way to free images from the device is to disable Persistent Images option and start rendering.

Cycles: first step for implementation of non-progressive sampler that handles direct and indirect lighting differently. Rather than picking one light for each point on the path, it now loops over all lights for direct lighting. For indirect lighting it still picks a random light each time. It gives control over the number of AA samples, and the number of Diffuse, Glossy, Transmission, AO, Mesh Light, Background and Lamp samples for each AA sample. This helps tuning render performance/noise and tends to give less noise for renders dominated by direct lighting. This sampling mode only works on the CPU, and still needs proper tile rendering to show progress (will follow tommorrow or so), because each AA sample can be quite slow now and so the delay between each update wil be too long.

Cycles: first step for implementation of non-progressive sampler that handles direct and indirect lighting differently. Rather than picking one light for each point on the path, it now loops over all lights for direct lighting. For indirect lighting it still picks a random light each time. It gives control over the number of AA samples, and the number of Diffuse, Glossy, Transmission, AO, Mesh Light, Background and Lamp samples for each AA sample. This helps tuning render performance/noise and tends to give less noise for renders dominated by direct lighting. This sampling mode only works on the CPU, and still needs proper tile rendering to show progress (will follow tommorrow or so), because each AA sample can be quite slow now and so the delay between each update wil be too long.

Cycles: * Add alpha pass output, to use set Transparent option in Film panel. * Add Holdout closure (OSL terminology), this is like the Sky option in the internal renderer, objects with this closure show the background / zero alpha. * Add option to use Gaussian instead of Box pixel filter in the UI. * Remove camera response curves for now, they don't really belong here in the pipeline, should be moved to compositor. * Output full float values for rendering now, previously was only byte precision. * Add a patch from Thomas to get a preview passes option, but still disabled because it isn't quite working right yet. * CUDA: don't compile shader graph evaluation inline. * Convert tabs to spaces in python files.

Cycles: Force bottom-to-top tile order for viewport rendering This commit overrides the user's choice of tile order in the case of viewport rendering and always uses bottom-to-top instead. This was already done until the TileManager redesign, but since it removed the distinction between viewport and regular rendering in the manager, the viewport was now also using the selected order. Since this requires sorting of the generated tiles, it slows down rendering a bit. With the forced bottom-to-top order, this sorting step can now be avoided again. Since the tile order is invisible anyways for viewport rendering, this commit won't have any impact on users (apart from a slight speedup).

Cycles: progressive refine option Just makes progressive refine :) This means the whole image would be refined gradually using as much threads as it's set in performance settings. Having enough tiles is required to have this option working as it's expected. Technically it's implemented by repeatedly computing next sample for all the tiles before switching to next sample. This works around 7-12% slower than regular tile-based rendering, so use this option only if you really need it. This commit also fixes progressive update of image when Save Buffers option is enabled. And one more thing this commit fixes is handling display buffer with Save Buffers option enabled. If this option is enabled image buffer wouldn't have neither byte nor float buffer until image is fully rendered which could backfire in missing image while rendering in cases color management cache became full. This issue solved by allocating byte buffer for image buffer from tile update callback. Patch was reviewed by Brecht. He also made some minor edits to original version to patch. Thanks, man!

Cycles: viewport render now takes scene color management settings into account, except for curves, that's still missing from the OpenColorIO GLSL shader. The pixels are stored in a half float texture, converterd from full float with native GPU instructions and SIMD on the CPU, so it should be pretty quick. Using a GLSL shader is useful for GPU render because it avoids a copy through CPU memory.
