2018-11-23Cycles: Improved robustness of hair motion blur.motion_curve_fixStefan Werner
In some instances, the number of control vertices of a hair could change mid-frame. Cycles would then be unable to calculate proper motion blur for those hairs. This adds interpolated CVs to fill in for the missing data. While this will not necessarily result in a fully accurate reconstruction of the guide hair, it preserves motion blur instead of disabling it.

WITH_CYCLES_CUDA_BINARIES was set as a regular variable causing it to be overwritten by the release.cmake settings.

I wouldn't mind changing style to have space after keyword, but there was no official code style change proposed.

assuming sRGB I've limited it to just the RGB<->XYZ stuff for now, correct image handling is the next step. Reviewers: brecht, sergey Differential Revision: https://developer.blender.org/D3478

2018-03-10Code refactor: make Transform always affine, dropping last row.Brecht Van Lommel
This save a little memory and copying in the kernel by storing only a 4x3 matrix instead of a 4x4 matrix. We already did this in a few places, and those don't need to be special exceptions anymore now.

nvcc is very picky regarding compiler versions, severely limiting the compiler we can use, this commit adds a nvrtc based compiler that'll allow us to build the cubins even if the host compiler is unsupported. for details see D2913. Differential Revision: http://developer.blender.org/D2913

There was some changes about namespaces, which causes ambiguities. Replaces using namespace with an explicit symbols we need. Is good idea to NOT pull in the whole namespace anyway!

Similar to previous commit for Gflags.
2017-04-21CMake: Add option to link against system-wide Gflags librarySergey Sharybin
It is disabled by default, so should not affect existing configurations. Main benefits of this goes as: - Linux distros can use that to avoid libraries duplication and link blender package against gflags package from the system. - It it easier to test whether Blender works with updated version of Gflags prior to re-bundling the library.

2016-12-03Cycles: Refactor Progress system to provide better estimatesLukas Stockner
The Progress system in Cycles had two limitations so far: - It just counted tiles, but ignored their size. For example, when rendering a 600x500 image with 512x512 tiles, the right 88x500 tile would count for 50% of the progress, although it only covers 15% of the image. - Scene update time was incorrectly counted as rendering time - therefore, the remaining time started very long and gradually decreased. This patch fixes both problems: First of all, the Progress now has a function to ignore time spans, and that is used to ignore scene update time. The larger change is the tile size: Instead of counting samples per tile, so that the final value is num_samples*num_tiles, the code now counts every sample for every pixel, so that the final value is num_samples*num_pixels. Along with that, some unused variables were removed from the Progress and Session classes.

2016-08-24Cycles Standalone: Fix support for subdivision meshesMai Lavelle
Changes from microdisplacement work broke previous support for subdivision meshes, sometimes leading to crashes; this makes things work again. Files that contain "patch" nodes will need to be updated to use meshes instead, as specifying patches was both inefficient and completely unsupported by the new subdivision code.

2016-08-10Cycles Standalone: Add option to set the tile size from the command lineLukas Stockner
Since the optimal values depend on the device used, this option doesn't make much sense in the XML. Therefore, it's now specified via the command line, just like the device itself.
2016-07-29Cycles microdisplacement: ngons and attributes for subdivision meshesMai Lavelle
This adds support for ngons and attributes on subdivision meshes. Ngons are needed for proper attribute interpolation as well as correct Catmull-Clark subdivision. Several changes are made to achieve this: - new primitive `SubdFace` added to `Mesh` - 3 more textures are used to store info on patches from subd meshes - Blender export uses loop interface instead of tessface for subd meshes - `Attribute` class is updated with a simplified way to pass primitive counts around and to support ngons. - extra points for ngons are generated for O(1) attribute interpolation - curves are temporally disabled on subd meshes to avoid various bugs with implementation - old unneeded code is removed from `subd/` - various fixes and improvements Reviewed By: brecht Differential Revision: https://developer.blender.org/D2108

2016-04-13Tweaks to the version string formationSergey Sharybin
Couple of things: - No need to use string streams to format the version string, we can do it at compile time and don't bother with anything at runtime. - Function declaration was wring and would have caused linking conflicts in cases when util_version.h was included from multiple places. We should have an utility function to get Cycles version so applications which are linked to Cycles dynamically can query the version, but that can't be done as an inlined function in header and would need to be a function properly exported to a global symbol table (aka, be implemented in a .cpp file).
2016-04-13Add a version number to Cycles standaloneThomas Dinges
Now Cycles has its own versioning, that is mainly interesting for external projects, which integrate the engine. We start with version 1.7.0. Reasons for that: * The engine is too mature for a 1.0 release. * We assume that Cycles inside of Blender 2.61 was version 0.1. We count upwards in 0.1 steps, therefore Cycles inside of Blender 2.77 would be 1.7. We use a common versioning scheme here, with 3 decimals for the major, minor and patch level. At the moment cycles --version can be used to display the version, easy to parse for external projects. The info will be added to the UI later aswell.
