Cycles: remove prefix from source code file names Remove prefix of filenames that is the same as the folder name. This used to help when #includes were using individual files, but now they are always relative to the cycles root directory and so the prefixes are redundant. For patches and branches, git merge and rebase should be able to detect the renames and move over code to the right file.

/* Shader Virtual Machine
*
* A shader is a list of nodes to be executed. These are simply read one after
* the other and executed, using an node counter. Each node and its associated
* data is encoded as one or more uint4's in a 1D texture. If the data is larger
* than an uint4, the node can increase the node counter to compensate for this.
* Floats are encoded as int and then converted to float again.
*
* Nodes write their output into a stack. All stack data in the stack is
* floats, since it's all factors, colors and vectors. The stack will be stored
* in local memory on the GPU, as it would take too many register and indexes in
* ways not known at compile time. This seems the only solution even though it
* may be slow, with two positive factors. If the same shader is being executed,
Code cleanup: remove some more unused code after recent CUDA changes.

* memory access will be coalesced and cached.

* The result of shader execution will be a single closure. This means the
* closure type, associated label, data and weight. Sampling from multiple
* closures is supported through the mix closure node, the logic for that is
* mostly taken care of in the SVM compiler.

Cycles: Kernel address space changes for MSL This is the first of a sequence of changes to support compiling Cycles kernels as MSL (Metal Shading Language) in preparation for a Metal GPU device implementation. MSL requires that all pointer types be declared with explicit address space attributes (device, thread, etc...). There is already precedent for this with Cycles' address space macros (ccl_global, ccl_private, etc...), therefore the first step of MSL-enablement is to apply these consistently. Line-for-line this represents the largest change required to enable MSL. Applying this change first will simplify future patches as well as offering the emergent benefit of enhanced descriptiveness. The vast majority of deltas in this patch fall into one of two cases: - Ensuring ccl_private is specified for thread-local pointer types - Ensuring ccl_global is specified for device-wide pointer types Additionally, the ccl_addr_space qualifier can be removed. Prior to Cycles X, ccl_addr_space was used as a context-dependent address space qualifier, but now it is either redundant (e.g. in struct typedefs), or can be replaced by ccl_global in the case of pointer types. Associated function variants (e.g. lcg_step_float_addrspace) are also redundant. In cases where address space qualifiers are chained with "const", this patch places the address space qualifier first. The rationale for this is that the choice of address space is likely to have the greater impact on runtime performance and overall architecture. The final part of this patch is the addition of a metal/compat.h header. This is partially complete and will be extended in future patches, paving the way for the full Metal implementation.

Associated function variants (e.g. lcg_step_float_addrspace) are also redundant. In cases where address space qualifiers are chained with "const", this patch places the address space qualifier first. The rationale for this is that the choice of address space is likely to have the greater impact on runtime performance and overall architecture. The final part of this patch is the addition of a metal/compat.h header. This is partially complete and will be extended in future patches, paving the way for the full Metal implementation.

Cycles: Kernel address space changes for MSL This is the first of a sequence of changes to support compiling Cycles kernels as MSL (Metal Shading Language) in preparation for a Metal GPU device implementation. MSL requires that all pointer types be declared with explicit address space attributes (device, thread, etc...). There is already precedent for this with Cycles' address space macros (ccl_global, ccl_private, etc...), therefore the first step of MSL-enablement is to apply these consistently. Line-for-line this represents the largest change required to enable MSL. Applying this change first will simplify future patches as well as offering the emergent benefit of enhanced descriptiveness.

Cycles: add bevel shader, for raytrace based rounded edges. The algorithm averages normals from nearby surfaces. It uses the same sampling strategy as BSSRDFs, casting rays along the normal and two orthogonal axes, and combining the samples with MIS. The main concern here is that we are introducing raytracing inside shader evaluation, which could be quite bad for GPU performance and stack memory usage. In practice it doesn't seem so bad though. Note that using this feature can easily slow down renders 20%, and that if you care about performance then it's better to use a bevel modifier. Mainly this is useful for baking, and for cases where the mesh topology makes it difficult for the bevel modifier to work well. Differential Revision: https://developer.blender.org/D2803

Cycles: Initial work towards selective nodes support compilation The goal is to be able to compile kernel with nodes which are actually needed to render current scene, hence improving performance of the kernel, The idea is: - Have few node groups, starting with a group which contains nodes are used really often, and then couple of groups which will be extension of this one. - Have feature-based nodes disabling, so it's possible to disable nodes related to features which are not used with the currently used nodes group. This commit only lays down needed routines for this approach, actual split will happen later after gathering statistics from bunch of production scenes.

/* Main Interpreter Loop */
Cycles: decouple shadow paths from main path on GPU The motivation for this is twofold. It improves performance (5-10% on most benchmark scenes), and will help to bring back transparency support for the ambient occlusion pass. * Duplicate some members from the main path state in the shadow path state. * Add shadow paths incrementally to the array similar to what we do for the shadow catchers. * For the scheduling, allow running shade surface and shade volume kernels as long as there is enough space in the shadow paths array. If not, execute shadow kernels until it is empty. * Add IntegratorShadowState and ConstIntegratorShadowState typedefs that can be different between CPU and GPU. For GPU both main and shadow paths juse have an integer for SoA access. Bt with CPU it's a different pointer type so we get type safety checks in code shared between CPU and GPU. * For CPU, add a separate IntegratorShadowStateCPU struct embedded in IntegratorShadowState. * Update various functions to take the shadow state, and make SVM take either type of state using templates.

Cycles: decouple shadow paths from main path on GPU The motivation for this is twofold. It improves performance (5-10% on most benchmark scenes), and will help to bring back transparency support for the ambient occlusion pass. * Duplicate some members from the main path state in the shadow path state. * Add shadow paths incrementally to the array similar to what we do for the shadow catchers. * For the scheduling, allow running shade surface and shade volume kernels as long as there is enough space in the shadow paths array. If not, execute shadow kernels until it is empty. * Add IntegratorShadowState and ConstIntegratorShadowState typedefs that can be different between CPU and GPU. For GPU both main and shadow paths juse have an integer for SoA access. Bt with CPU it's a different pointer type so we get type safety checks in code shared between CPU and GPU. * For CPU, add a separate IntegratorShadowStateCPU struct embedded in IntegratorShadowState. * Update various functions to take the shadow state, and make SVM take either type of state using templates.

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 http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/Textures

Cycles: Add Support for IES files as textures for light strength This patch adds support for IES files, a file format that is commonly used to store the directional intensity distribution of light sources. The new IES node is supposed to be plugged into the Strength input of the Emission node of the lamp. Since people generating IES files do not really seem to care about the standard, the parser is flexible enough to accept all test files I have tried. Some common weirdnesses are distributing values over multiple lines that should go into one line, using commas instead of spaces as delimiters and adding various useless stuff at the end of the file. The user interface of the node is similar to the script node, the user can either select an internal Text or load a file. Internally, IES files are handled similar to Image textures: They are stored in slots by the LightManager and each unique IES is assigned to one slot. The local coordinate system of the lamp is used, so that the direction of the light can be changed. For UI reasons, it's usually best to add an area light, rotate it and then change its type, since especially the point light does not immediately show its local coordinate system in the viewport.

I'll see with Brecht later. But overall I don't know if that's any fast.

Cycles / Wavelength to RGB node: * Added a node to convert wavelength (in nanometer, from 380nm to 780nm) to RGB values. This can be useful to match real world colors easier. Example render: http://www.pasteall.org/pic/show.php?id=53202 ToDo: * Move some functions into an util file, maybe a common util_color.h or so. * Test GPU, unfortunately sm_21 doesn't work for me yet.

Cycles / Blackbody node: * First (brute force) implementation for SVM. This works and delivers the same result as OSL, but it's slow. * Code inside svm_blackbody.h inspired by a patch by Philipp Oeser (#35698), thanks. Ideas: * Use a lookup table to perform the calculations on render/ level. * Implement it as a RNA property only, and do the calculation like Sun/Sky precompute.

#ifdef __SHADER_RAYTRACE__
Cycles: add bevel shader, for raytrace based rounded edges. The algorithm averages normals from nearby surfaces. It uses the same sampling strategy as BSSRDFs, casting rays along the normal and two orthogonal axes, and combining the samples with MIS. The main concern here is that we are introducing raytracing inside shader evaluation, which could be quite bad for GPU performance and stack memory usage. In practice it doesn't seem so bad though. Note that using this feature can easily slow down renders 20%, and that if you care about performance then it's better to use a bevel modifier. Mainly this is useful for baking, and for cases where the mesh topology makes it difficult for the bevel modifier to work well. Differential Revision: https://developer.blender.org/D2803
