2020-03-19Cleanup: `make format` after SortedIncludes changeDalai Felinto
2020-03-18Fix (harmless) use of uninitialized variables in CyclesBrecht Van Lommel
2020-03-18Volumes: add render settings for volume datablockBrecht Van Lommel
* Space: volume density and step size in object or world space * Step Size: override automatic step size * Clipping: values below this are ignored for tighter volume bounds The last two are Cycles only currently. Ref T73201
2020-03-18Cycles: change volume step size controls, auto adjust based on voxel sizeBrecht Van Lommel
By default it will now set the step size to the voxel size for smoke and volume objects, and 1/10th the bounding box for procedural volume shaders. New settings are: * Scene render/preview step rate: to globally adjust detail and performance * Material step rate: multiplied with auto detected per-object step size * World step size: distance to steo for world shader Differential Revision: https://developer.blender.org/D1777
2020-03-18Cycles: support for rendering of new Hair object prototypeBrecht Van Lommel
Ref T68981
2020-03-18Cycles: support rendering new Volume object typeBrecht Van Lommel
Voxels are loaded directly from the OpenVDB grid. Rendering still only supports dense grid, so memory usage is not great for sparse volumes, this is to be addressed in the future. Ref T73201
2020-03-18Cycles: support for different 3D transform per volume gridBrecht Van Lommel
This is not yet fully supported by automatic volume bounds but works fine in most cases that will have mostly matching bounds. Ref T73201
2020-03-17Cleanup: process colorspace conversion with a 1D pixel arrayBrecht Van Lommel
No need to assume it's 2D or 3D.
2020-03-16Cycles: Fix bad escape character used for dotSergey Sharybin
2020-03-16Fix T74776: Cycles crash with missing image texture after recent changesBrecht Van Lommel
2020-03-16UI: Show decorators for lights when using CyclesWilliam Reynish
This matches Eevee, and also the rest of Blender.
2020-03-12Fix memory leak in recent Cycles image texture refactorBrecht Van Lommel
2020-03-12Cleanup: add device_texture for images, distinct from other global memoryBrecht Van Lommel
There was too much image texture specific stuff in device_memory, and too much code duplication between devices.
2020-03-12Fix build error with recent OpenImageIO versionsBrecht Van Lommel
2020-03-12Cleanup: spelling, clang-formatCampbell Barton
2020-03-11Fix T73626: crash scrubbing timeline with Cycles viewport and smoke/fireBrecht Van Lommel
2020-03-11Cleanup: refactor image loading to use abstract ImageLoader base classBrecht Van Lommel
Rather than passing around void pointers, various Blender image sources now subclass this. OIIO is also just another type of image loader. Also fixes T67718: Cycles viewport render crash editing point density settings
2020-03-11Cleanup: add ImageHandle to centralize image ownership logicBrecht Van Lommel
2020-03-11Cycles: add internal default volume shader, to be used for new volume objectBrecht Van Lommel
This is mostly straightforward, but required some refactoring to ensure that the default volume material does not always turn on the volume feature for GPU rendering.
2020-03-11Cleanup: remove foreach include from header, conflicts with OpenVDBBrecht Van Lommel
2020-03-11Fix Optix build error on Linux with some compilersBrecht Van Lommel
2020-03-11Fix Cycles crash in BVH8 build due to out of bounds memory accessGiovanni Remigi
Differential Revision: https://developer.blender.org/D7114
2020-03-11Cleanup: stop encoding image data type in slot indexBrecht Van Lommel
This is legacy code from when we had a fixed number of textures.
2020-03-11Fix Cycles link error with debug + asan after RTTI changesBrecht Van Lommel
2020-03-11Cycles: disable RTTI only for OSL files, other libraries like OpenVDB need itBrecht Van Lommel
This is a bit weak since it's not entirely clear where the boundary is, but tested to build and pass tests on all platforms.
2020-03-11Fix Cycles incorrect result when compressing some 8 bit log colorspace imagesBrecht Van Lommel
Don't clamp and do premultiply after color space conversion.
2020-03-11Cycles: add view layer setting to exclude volumes, like hair and surfacesBrecht Van Lommel
2020-03-11UI: show more digits for adaptive sampling noise thresholdBrecht Van Lommel
2020-03-11Cleanup: clang-formatCampbell Barton
2020-03-10Cycles: Fixed Shadow and Mist passes with adaptive sampling.Stefan Werner
This also fixes a side-effect where turning on UV pass but leaving Shadow pass turned off destroyed the Combined pass.
2020-03-10Cycles: Using OpenCL popcount() in PMJ sampler.Stefan Werner
2020-03-09Cleanup: avoid (harmless) race condition reported by HelgrindJohan Walles

2020-03-05Fix T74393: Cycles crashes when both OSL and Optix Denoising are enabledPatrick Mours
Enabling viewport denoising causes Cycles to use a multi-device, which always returned NULL when asked for OSL memory and would subsequently crash. This fixes that by returning the correct OSL memory pointer from the CPU device in the special viewport denoising multi-device.
2020-03-05Adaptive Sampling for Cycles.Stefan Werner
This feature takes some inspiration from "RenderMan: An Advanced Path Tracing Architecture for Movie Rendering" and "A Hierarchical Automatic Stopping Condition for Monte Carlo Global Illumination" The basic principle is as follows: While samples are being added to a pixel, the adaptive sampler writes half of the samples to a separate buffer. This gives it two separate estimates of the same pixel, and by comparing their difference it estimates convergence. Once convergence drops below a given threshold, the pixel is considered done. When a pixel has not converged yet and needs more samples than the minimum, its immediate neighbors are also set to take more samples. This is done in order to more reliably detect sharp features such as caustics. A 3x3 box filter that is run periodically over the tile buffer is used for that purpose. After a tile has finished rendering, the values of all passes are scaled as if they were rendered with the full number of samples. This way, any code operating on these buffers, for example the denoiser, does not need to be changed for per-pixel sample counts.

2020-03-05Addons: deprecate 'wiki_url'Aaron Carlisle
When running with debug enabled ('-d' argument), warnings are printed for add-ons which are not yet updated. Reminder to name things based on what they do, not the technologies they use :)
2020-03-05Cleanup: formatting, strip trailing spaceCampbell Barton
2020-03-04Cleanup: cmake indentationCampbell Barton
2020-03-02Cycles: add Progressive Multi-Jitter sampling patternStefan Werner
This sampling pattern is particularly suited to adaptive sampling, and will be used for that upcoming feature. Based on "Progressive Multi-Jittered Sample Sequences" by Per Christensen, Andrew Kensler and Charlie Kilpatrick. Ref D4686
2020-03-02Shading: Add invert option to Vector Rotate NodeCharlie Jolly
Checkbox to invert rotation angle, suggested by @simonthommes Differential Revision: https://developer.blender.org/D6932
2020-02-28Cycles: Rework tile scheduling for denoisingPatrick Mours
This fixes denoising being delayed until after all rendering has finished. Instead, tile-based denoising is now part of the "RENDER" task again, so that it is all in one task and does not cause issues with dedicated task pools where tasks are serialized.

2020-02-28Fix CUDA out of memory error with OptiX viewport denoising on small GPUsPatrick Mours
This makes the memory allocation for the denoiser state use the memory allocator in Cycles, which will evict textures to host memory when there is not enough space on the device. This means the allocation for the denoiser state won't just fail if there is no more space and instead more space is made for it to work. Also simplifies code somewhat.
