fb56dbc2af Cycles: procedural texture nodes reorganization. This will break existing files
using them, but rather do it now that I have the chance still. Highlights:

* Wood and Marble merged into a single Wave texture
* Clouds + Distorted Noise merged into new Noise node
* Blend renamed to Gradient
* Stucci removed, was mostly useful for old bump
* Noise removed, will come back later, didn't actually work yet
* Depth setting is now Detail socket, which accepts float values
* Scale socket instead of Size socket

72929172dd Cycles: add location/rotate/scale and XYZ mapping options for all texture nodes,
to reduce the amount of nodes needed to set up a simple texture.

These are currently editable in the texture properties tab, still need to make
them available in the node editor. Projection and color modification options will
be added later, they're not implemented yet but allocated already to avoid
version patches later.

Also an issue with the XYZ mapping is that when you set one to None, texture and
material draw mode doesn't draw the image texture well, OpenGL doesn't seem to
like the degenerate texture matrix?

7b06c1718b Cycles: material "sample as light" option, to make the integrator sample the
object as a mesh light or not. This may result in more/less noisy renders
depending on the situation, but should converge to the same result.

9c959d98fe Cycles: make Attribute node work, code for it was implemented in kernel, only
missing was the ability to specify the attribute name in the node. This makes
it possible to use multiple uv or vertex color layers now.

9ebfcea8f3 Cycles: revert commit that joined surface/volume socket into a single shader socket,
on second thought this makes it a bit too difficult to understand what's going on.

310b25c388 Cycles: code refactoring to split out code from mapping node. 2011-10-12 22:42:13 +00:00
9ec1114765 Cycles: make node with multiple input sockets with the same name work. Previously
nodes like Mix had their sockets renamed to Color1/Color2, but doing this breaks
compatibility for the internal renderer, so restored it now.

7503a7edfb Cycles: replace surface/volume sockets in output nodes with a single shader socket,
decided it's better to render objects as either surface or volume.

This may break the volume rendering patch, but shaders with volume closures still
get tagged as having volume closures, so it should be fixable without too many
changes.

1ab9fc59b7 Cycles: fix a few more msvc issues with empty scenes and ustring setting. 2011-10-03 17:42:24 +00:00
cdee3435c6 Cycles: internal changes that should have no effect on user level yet, added
shader flags for various purposes, and some code for light types other than
points.

136d27b350 Cycles: add some volume nodes, they don't actually do anything, this is just
to give other developers who may want to work on this to get a starting point.

f4a9215d7c Cycles: svn merge -r39870:r40266 https://svn.blender.org/svnroot/bf-blender/trunk/blender
Merging the node changes required a lot of conflict resolution, fixed the
issues I could find but if you want stability you might want to wait a bit
before updating.

66b1dfae89 Cycles: tweaks to properties and nodes
* Passes renamed to samples
* Camera lens radius renamed to aperature size/blades/rotation
* Glass and fresnel nodes input is now index of refraction
* Glossy and velvet fresnel socket removed
* Mix/add closure node renamed to mix/add shader node
* Blend weight node added for shader mixing weights

There is some version patching code for reading existing files, but it's not
perfect, so shaders may work a bit different.

f97d7b234d Cycles: fix crash with group node sockets that don't connect to any node
inside the group.

df625253ac Cycles:
* Add max diffuse/glossy/transmission bounces
* Add separate min/max for transparent depth
* Updated/added some presets that use these options
* Add ray visibility options for objects, to hide them from
  camera/diffuse/glossy/transmission/shadow rays
* Is singular ray output for light path node

bae896691a 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.

f7b9c85871 Cycles: fix some invalid memory access problems found by running the windows build in debug mode. 2011-08-21 10:32:15 +00:00
eedcba7ed5 Cycles: for material/world/lamps, if use_nodes is disabled, show some
default shaders instead of black.

922bb24865 Cycles: color space control for image/environment texture nodes. Ideally would
be automated but need to think about how to do this, not so simply in a node
system. But guideline for now is, for color textures set to sRGB, for things like
bump or roughness map, set to Linear.

da376e0237 Cycles render engine, initial commit. This is the engine itself, blender modifications and build instructions will follow later.
Cycles uses code from some great open source projects, many thanks them:

* BVH building and traversal code from NVidia's "Understanding the Efficiency of Ray Traversal on GPUs":
http://code.google.com/p/understanding-the-efficiency-of-ray-traversal-on-gpus/
* Open Shading Language for a large part of the shading system:
http://code.google.com/p/openshadinglanguage/
* Blender for procedural textures and a few other nodes.
* Approximate Catmull Clark subdivision from NVidia Mesh tools:
