- changed calculus for area light to use double precision. Using float already gave noise with area size of 0.1. Limited buttons to minimum value of 0.01 for area light. For people who want smaller they can scale it down in 3d, effectively reducing the energy then as well.

struct HaloRen;
Phew, a lot of work, and no new features... Main target was to make the inner rendering loop using no globals anymore. This is essential for proper usage while raytracing, it caused a lot of hacks in the raycode as well, which even didn't work correctly for all situations (textures especially). Done this by creating a new local struct RenderInput, which replaces usage of the global struct Render R. The latter now only is used to denote image size, viewmatrix, and the like. Making the inner render loops using no globals caused 1000s of vars to be changed... but the result definitely is much nicer code, which enables making 'real' shaders in a next stage. It also enabled me to remove the hacks from ray.c Then i went to the task of removing redundant code. Especially the calculus of texture coords took place (identical) in three locations. Most obvious is the change in the unified render part, which is much less code now; it uses the same rendering routines as normal render now. (Note; not for halos yet!) I also removed 6 files called 'shadowbuffer' something. This was experimen- tal stuff from NaN days. And again saved a lot of double used code. Finally I went over the blenkernel and blender/src calls to render stuff. Here the same local data is used now, resulting in less dependency. I also moved render-texture to the render module, this was still in Kernel. (new file: texture.c) So! After this commit I will check on the autofiles, to try to fix that. MSVC people have to do it themselves. This commit will need quite some testing help, but I'm around!

Three features; - Live scanline updates while rendering Using a timer system, each second now the tiles that are being processed are checked if they could use display. To make this work pretty, I had to use the threaded 'tile processor' for a single thread too, but that's now proven to be stable. Also note that these updates draw per layer, including ztransp progress separately from solid render. - Recode of ztransp OSA Until now (since blender 1.0) the ztransp part was fully rendered and added on top of the solid part with alpha-over. This adding was done before the solid part applied sub-pixel sample filtering, causing the ztransp layer to be always too blurry. Now the ztransp layer uses same sub=pixel filter, resulting in the same AA level (and filter results) as the solid part. Quite noticable with hair renders. - Vector buffer support & preliminary vector-blur Node Using the "Render Layer" panel "Vector" pass button, the motion vectors per pixel are calculated and stored. Accessible via the Compositor. The vector-blur node is horrible btw! It just uses the length of the vector to apply a filter like with current (z)blur. I'm committing it anyway, I'll experiment with it further, and who knows some surprise code shows up!

struct ShadeResult;
Render Monster support: (part 1) Removed all limitations from render code for maximum threads. The only define for this now is in BLI_threads.h, and currently set to 8. Note that each thread renders an entire tile, and also allocates the buffers for the tiles, so; more threads might work better with smaller tiles. IMPORTANT: node system won't work yet with more than 2 threads! So, don't try material nodes or compositing with over 2 threads. That I'll commit later today. What does work (should work :) is AO and soft shadow now.

struct World;
Next stage of RenderPipe refactor: now everything within the pixel was tackled. Resulting features: - render passes - new pass: Object Index, for masking - sub-sample alpha masks Docs: http://mediawiki.blender.org/index.php/BlenderDev/RenderPipeline http://www.blender3d.org/cms/Render_Passes.829.0.html http://www.blender3d.org/cms/New_Render_features.774.0.html Note that these changes might mean things to not render fully identical... For the next days a lot of testing is needed!

Render Instancing ================= Big commit, but little user visible changes. - Dupliverts and duplifaces are now rendered as instances, instead of storing all of the geometry for each dupli, now an instance is created with a matrix transform refering to the source object. This should allow us to render tree leaves more memory efficient. - Radiosity and to some degree raytracing of such objects is not really efficient still. For radiosity this is fundamentally hard to solve, but raytracing an octree could be created for each object, but the current octree code with it's fixed size doesn't allow this efficiently. - The regression tests survived, but with I expect that some bugs will pop up .. hopefully not too many :). Implementation Notes ==================== - Dupligroups and linked meshes are not rendered as instances yet, since they can in fact be different due to various reasons, instancing of these types of duplis that are the same can be added for them at a later point. - Each ObjectRen now stores it's own database, instead of there being one big databases of faces, verts, .. . Which objects that are actually rendered are defined by the list of ObjectRenInstances, which all refer to an ObjectRen. - Homogeneous coordinatess and clipping is now not stored in vertices anymore, but instead computed on the fly. This couldn't work for instances. That does mean some extra computation has to be done, but memory lookups can be slow too, and this saves some memory. Overall I didn't find a significant speed impact. - OSA rendering for solid and ztransp now is different. Instead of e.g. going 8 times over the databases times and rendering the z-buffer, it now goes over the database once and renders each polygon 8 times. That was necessary to keep instances efficient, and can also give some performance improvement without instances. - There was already instancing support in the yafray export code, now it uses Blender's render instances for export. - UV and color layer storage in the render was a bit messy before, now should be easier to understand. - convertblender.c was reorganized somewhat. Regular render, speedvector and baking now use a single function to create the database, previously there was code duplicated for it. - Some of these changes were done with future multithreading of scene and shadow buffer creation in mind, though especially for scene creation much work remains to be done to make it threadsafe, since it also involves a lot of code from blenkernel, and there is an ugly conflict with the way dupli groups work here .. though in the render code itself it's almost there.

Giant commit! A full detailed description of this will be done later... is several days of work. Here's a summary: Render: - Full cleanup of render code, removing *all* globals and bad level calls all over blender. Render module is now not called abusive anymore - API-fied calls to rendering - Full recode of internal render pipeline. Is now rendering tiles by default, prepared for much smarter 'bucket' render later. - Each thread now can render a full part - Renders were tested with 4 threads, goes fine, apart from some lookup tables in softshadow and AO still - Rendering is prepared to do multiple layers and passes - No single 32 bits trick in render code anymore, all 100% floats now. Writing images/movies - moved writing images to blender kernel (bye bye 'schrijfplaatje'!) - made a new Movie handle system, also in kernel. This will enable much easier use of movies in Blender PreviewRender: - Using new render API, previewrender (in buttons) now uses regular render code to generate images. - new datafile 'preview.blend.c' has the preview scenes in it - previews get rendered in exact displayed size (1 pixel = 1 pixel) 3D Preview render - new; press Pkey in 3d window, for a panel that continuously renders (pkey is for games, i know... but we dont do that in orange now!) - this render works nearly identical to buttons-preview render, so it stops rendering on any event (mouse, keyboard, etc) - on moving/scaling the panel, the render code doesn't recreate all geometry - same for shifting/panning view - all other operations (now) regenerate the full render database still. - this is WIP... but big fun, especially for simple scenes! Compositor - Using same node system as now in use for shaders, you can composit images - works pretty straightforward... needs much more options/tools and integration with rendering still - is not threaded yet, nor is so smart to only recalculate changes... will be done soon! - the "Render Result" node will get all layers/passes as output sockets - The "Output" node renders to a builtin image, which you can view in the Image window. (yes, output nodes to render-result, and to files, is on the list!) The Bad News - "Unified Render" is removed. It might come back in some stage, but this system should be built from scratch. I can't really understand this code... I expect it is not much needed, especially with advanced layer/passes control - Panorama render, Field render, Motion blur, is not coded yet... (I had to recode every single feature in render, so...!) - Lens Flare is also not back... needs total revision, might become composit effect though (using zbuffer for visibility) - Part render is gone! (well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall. Now go compiling!

Biiig commit! Thanks to 2-3 weeks of cvs freeze... Render: - New; support for dual CPU render (SDL thread) Currently only works with alternating scanlines, but gives excellent performance. For both normal render as unified implemented. Note the "mutex" locks on z-transp buffer render and imbuf loads. - This has been made possible by major cleanups in render code, especially getting rid of globals (example Tin Tr Tg Tb Ta for textures) or struct OSA or using Materials or Texture data to write to. - Made normal render fully 4x32 floats too, and removed all old optimizes with chars or shorts. - Made normal render and unified render use same code for sky and halo render, giving equal (and better) results for halo render. Old render now also uses PostProcess options (brightness, mul, gamma) - Added option ("FBuf") in F10 Output Panel, this keeps a 4x32 bits buffer after render. Using PostProcess menu you will note an immediate re- display of image too (32 bits RGBA) - Added "Hue" and "Saturation" sliders to PostProcess options - Render module is still not having a "nice" API, but amount of dependencies went down a lot. Next todo: remove abusive "previewrender" code. The last main global in Render (struct Render) now can be re-used for fully controlling a render, to allow multiple "instances" of render to open. - Renderwindow now displays a smal bar on top with the stats, and keeps the stats after render too. Including "spare" page support. Not only easier visible that way, but also to remove the awkward code that was drawing stats in the Info header (extreme slow on some ATIs too) - Cleaned up blendef.h and BKE_utildefines.h, these two had overlapping defines. - I might have forgotten stuff... and will write a nice doc on the architecture!

Negative zmask rendering: now there is a setting to render everything behind the zmask instead of in front. Might need tweaks, and doesn't work with halo yet.

Bugfix #5199 Irregular shadow buffer, for solid OSA case, suffered aliasing. This caused by optimized storage of shadow factors in 1 pixel (averaged for all sub samples). That didn't work well really... Now the code uses same method as for transparent faces, storing results for each sample.

Note the "mutex" locks on z-transp buffer render and imbuf loads. - This has been made possible by major cleanups in render code, especially getting rid of globals (example Tin Tr Tg Tb Ta for textures) or struct OSA or using Materials or Texture data to write to. - Made normal render fully 4x32 floats too, and removed all old optimizes with chars or shorts. - Made normal render and unified render use same code for sky and halo render, giving equal (and better) results for halo render. Old render now also uses PostProcess options (brightness, mul, gamma) - Added option ("FBuf") in F10 Output Panel, this keeps a 4x32 bits buffer after render. Using PostProcess menu you will note an immediate re- display of image too (32 bits RGBA) - Added "Hue" and "Saturation" sliders to PostProcess options - Render module is still not having a "nice" API, but amount of dependencies went down a lot. Next todo: remove abusive "previewrender" code. The last main global in Render (struct Render) now can be re-used for fully controlling a render, to allow multiple "instances" of render to open. - Renderwindow now displays a smal bar on top with the stats, and keeps the stats after render too. Including "spare" page support. Not only easier visible that way, but also to remove the awkward code that was drawing stats in the Info header (extreme slow on some ATIs too) - Cleaned up blendef.h and BKE_utildefines.h, these two had overlapping defines. - I might have forgotten stuff... and will write a nice doc on the architecture!

Two fixes in one commit. - The ortho render recode had a weak method to calculate the Z value of the render coordinate (shi.co[2]). Worked OK for normal render, but not in unified, giving big errors in Ortho Unfied render. Solved with proper math, using face equation a*x+b*y+c*y=d. Dunno why I didn't do it in first place. :) - Bug fix #2493. Edge render gave much different result for Ortho. This was due to overflows in the integer math filtering zbuffer values. Cleaned it op properly, preventing any integer overflow now.

And a first threading fix; mist render still used a R global for storage. caused very bad stripes in render.

float mistfactor(float zcor, float *co); /* dist and height, return alpha */
Phew, a lot of work, and no new features... Main target was to make the inner rendering loop using no globals anymore. This is essential for proper usage while raytracing, it caused a lot of hacks in the raycode as well, which even didn't work correctly for all situations (textures especially). Done this by creating a new local struct RenderInput, which replaces usage of the global struct Render R. The latter now only is used to denote image size, viewmatrix, and the like. Making the inner render loops using no globals caused 1000s of vars to be changed... but the result definitely is much nicer code, which enables making 'real' shaders in a next stage. It also enabled me to remove the hacks from ray.c Then i went to the task of removing redundant code. Especially the calculus of texture coords took place (identical) in three locations. Most obvious is the change in the unified render part, which is much less code now; it uses the same rendering routines as normal render now. (Note; not for halos yet!) I also removed 6 files called 'shadowbuffer' something. This was experimen- tal stuff from NaN days. And again saved a lot of double used code. Finally I went over the blenkernel and blender/src calls to render stuff. Here the same local data is used now, resulting in less dependency. I also moved render-texture to the render module, this was still in Kernel. (new file: texture.c) So! After this commit I will check on the autofiles, to try to fix that. MSVC people have to do it themselves. This commit will need quite some testing help, but I'm around!

Here's a summary: Render: - Full cleanup of render code, removing *all* globals and bad level calls all over blender. Render module is now not called abusive anymore - API-fied calls to rendering - Full recode of internal render pipeline. Is now rendering tiles by default, prepared for much smarter 'bucket' render later. - Each thread now can render a full part - Renders were tested with 4 threads, goes fine, apart from some lookup tables in softshadow and AO still - Rendering is prepared to do multiple layers and passes - No single 32 bits trick in render code anymore, all 100% floats now. Writing images/movies - moved writing images to blender kernel (bye bye 'schrijfplaatje'!) - made a new Movie handle system, also in kernel. This will enable much easier use of movies in Blender PreviewRender: - Using new render API, previewrender (in buttons) now uses regular render code to generate images. - new datafile 'preview.blend.c' has the preview scenes in it - previews get rendered in exact displayed size (1 pixel = 1 pixel) 3D Preview render - new; press Pkey in 3d window, for a panel that continuously renders (pkey is for games, i know... but we dont do that in orange now!) - this render works nearly identical to buttons-preview render, so it stops rendering on any event (mouse, keyboard, etc) - on moving/scaling the panel, the render code doesn't recreate all geometry - same for shifting/panning view - all other operations (now) regenerate the full render database still. - this is WIP... but big fun, especially for simple scenes! Compositor - Using same node system as now in use for shaders, you can composit images - works pretty straightforward... needs much more options/tools and integration with rendering still - is not threaded yet, nor is so smart to only recalculate changes... will be done soon! - the "Render Result" node will get all layers/passes as output sockets - The "Output" node renders to a builtin image, which you can view in the Image window. (yes, output nodes to render-result, and to files, is on the list!) The Bad News - "Unified Render" is removed. It might come back in some stage, but this system should be built from scratch. I can't really understand this code... I expect it is not much needed, especially with advanced layer/passes control - Panorama render, Field render, Motion blur, is not coded yet... (I had to recode every single feature in render, so...!) - Lens Flare is also not back... needs total revision, might become composit effect though (using zbuffer for visibility) - Part render is gone! (well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall.

void zbufshade_sss_tile(struct RenderPart *pa);
New rendering option: FSA! This completes the pipeline make-over, as started in 2006. With this option, during rendering, each sample for every layer and pass is being saved on disk (looks like non-antialiased images). Then the composite and color correction happens, then a clip to 0-1 range, and only in end all samples get combined - using sampling filters such as gauss/mitch/catmul. This results in artefact-free antialiased images. Even Z-combine or ID masks now work perfect for it! This is an unfinished commit btw; Brecht will finish this for strands. Also Halo doesnt work yet. To activate FSA: press "Save Buffers" and the new button next to it. :)

/* -------- ray.c ------- */
Refactor the raytracing code to split the tracing and shading parts into two separate files, raytrace.c and rayshade.c. The tracing code can now be used separately from the renderer (will be used in a later commit), and the raytracing acceleration structure can now also be easily replaced, if someone wants to experiment with that.

Render Monster support: (part 1) Removed all limitations from render code for maximum threads. The only define for this now is in BLI_threads.h, and currently set to 8. Note that each thread renders an entire tile, and also allocates the buffers for the tiles, so; more threads might work better with smaller tiles. IMPORTANT: node system won't work yet with more than 2 threads! So, don't try material nodes or compositing with over 2 threads. That I'll commit later today. What does work (should work :) is AO and soft shadow now.
