2019-10-15Fix T70605: incorrect darken and lighten rgb mix modeJacques Lucke
Differential Revision: https://developer.blender.org/D6058 Reviewers: brecht, fclem
2019-10-07Fix T70602: error baking with Cycles OpenCL after recent changesBrecht Van Lommel
2019-10-01Cycles: Fixed Camera inside volumes with Embree turned on.Stefan Werner
The Embree backend did not properly recognize when the camera was inside a volume and ended up ignoring those.
2019-09-25Cycles: Fix undefined behavior which can causes crashes with a misaligned ↵Patrick Mours
address error Cycles casts a pointer from ShaderDataTinyStorage to ShaderData, these structs by default had different alignments however (the former was 1-byte aligned, the latter 16-byte). This caused undefined behavior on at least the CUDA platform. Forcing both structs to use the same alignment fixes this. CUDA toolkits newer than 10.1 run into this because of a compiler optimization. Reviewed By: brecht Differential Revision: https://developer.blender.org/D5883
2019-09-23Revert part of "GPencil: Invert Paste operator and make Paste to Active default"Brecht Van Lommel
This commit accidentally undid a bunch of previous commits. Only the intended changes are left now.

2019-09-17Cycles: Viewport Rendering Memory ImprovementJeroen Bakker
Small memory reduction change by only storing the pixels of the combined pass when it is being shown in the viewport. Previously the combined pass was always calculated and present in the output buffer. The combined pass will still be calculated. It is a limitation in Blender that Cycles always had a combined pass. This patch will remove the limitation from the code base of Cycles. Blender still has the limitation, but will always request the combined renderpass when doing final rendering.

2019-09-13Cycles: add Optix device backendPatrick Mours
This uses hardware-accelerated raytracing on NVIDIA RTX graphics cards. It is still currently experimental. Most features are supported, but a few are still missing like baking, branched path tracing and using CPU memory. https://wiki.blender.org/wiki/Reference/Release_Notes/2.81/Cycles#NVIDIA_RTX For building with Optix support, the Optix SDK must be installed. See here for build instructions: https://wiki.blender.org/wiki/Building_Blender/CUDA Differential Revision: https://developer.blender.org/D5363
2019-09-13Cycles: add Optix support in the kernelPatrick Mours
This adds all the kernel side changes for the Optix backend. Ref D5363
2019-09-12Shading: Add Vertex Color node.OmarSquircleArt
This patch adds a new Vertex Color node. The node also returns the alpha of the vertex color layer as an output. Reviewers: brecht Differential Revision: https://developer.blender.org/D5767
2019-09-12Shading: Add More Features To The Voronoi Node.OmarSquircleArt
This patch allows the Voronoi node to operate in 1D, 2D, and 4D space. It also adds a Randomness input to control the randomness of the texture. Additionally, it adds three new modes of operation: - Smooth F1: A smooth version of F1 Voronoi with no discontinuities. - Distance To Edge: Returns the distance to the edges of the cells. - N-Sphere Radius: Returns the radius of the n-sphere inscribed in the cells. In other words, it is half the distance between the closest feature point and the feature point closest to it. And it removes the following three modes of operation: - F3. - F4. - Cracks. The Distance metric is now called Euclidean, and it computes the actual euclidean distance as opposed to the old method of computing the squared euclidean distance. This breaks backward compatibility in many ways, including the base case. Reviewers: brecht, JacquesLucke Differential Revision: https://developer.blender.org/D5743
2019-09-11Cycles: Display RenderPass in ViewportJeroen Bakker
This change allows the user to select a renderpass in the 3d viewport. Added support for external renderers to extend the `View3DShading` struct. This way Blender doesn't need to know the features an external render engine wants to support. Note that the View3DShading is also available in the scene->display.shading; although this is supported, it does not make sense for render engines to put something here as it is really scene/workbench related. Currently cycles assumes that it always needs to calculate the combined pass; it ignores the `pass_flag` in KernelFilm. We could optimize this but that was not in scope of this change Reviewed By: brecht Differential Revision: https://developer.blender.org/D5689
2019-09-09Fix T69686: Cycles OpenCL build error after recent changesBrecht Van Lommel
2019-09-09Shading: Extend Musgrave node to other dimensions.OmarSquircleArt
This patch extends Musgrave noise to operate in 1D, 2D, 3D, and 4D space. The Color output was also removed because it was identical to the Fac output. Reviewed By: brecht Differential Revision: https://developer.blender.org/D5566

2019-09-08Cycles: add bump map shadow terminator softening term for diffuse BSDFsLukas Stockner
This avoids artifacts for bump mapping and diffuse BSDFs, where the bump normal deviates far from the actual normal. Differential Revision: https://developer.blender.org/D5399

2019-09-05Fix: Compile error due to undefined isinf function.OmarSquircleArt
Some implementations of the standard c++ library doesn't define its functions in the global namespace. So the `isinf` function might fail in some systems. To fix this, we use the `ensure_finite` function instead. Reviewers: brecht Differential Revision: https://developer.blender.org/D5687
2019-09-05Shading: Rewrite Mapping node with dynamic inputs.OmarSquircleArt
This patch rewrites the Mapping node to support dynamic inputs. The Max and Min options have been removed. They can be added as Min and Max Vector Math nodes manually. Texture nodes still use the old matrix-based mapping. A new SVM node `NODE_TEXTURE_MAPPING` has been added to preserve this functionality. Similarly, in GLSL, a `mapping_mat4` function has been added. Reviewers: brecht, JacquesLucke
2019-09-04Shading: Extend Noise node to other dimenstions.OmarSquircleArt
This patch extends perlin noise to operate in 1D, 2D, 3D, and 4D space. The noise code has also been refactored to be more readable. The Color output and distortion patterns changed, so this patch breaks backward compatibility. This is due to the fact that we now use random offsets as noise seeds, as opposed to swizzling and constants offsets.

2019-08-26Cycles: code to optionally zero initialize some structs in the kernelBrecht Van Lommel
This will be used by Optix to help the compiler figure out scoping. It is not used by other devices currently, but worth testing if it helps there too. Ref D5363
2019-08-26GPencil: Invert Paste operator and make Paste to Active defaultAntonio Vazquez
Before there were two options: Paste to original layer called "Paste" and Paste to active layer called "Paste & Merge" Now, by default the paste is in active layer and the "Paste & Merge" has been renamed "Paste". For old "Paste", now is called "Paste by Layer" and it's not the default value anymore. Note: Minor edits to add icons not present in Differential revision.

2019-08-22Fix T69044: OpenCL fail due to bad fract function.OmarSquircleArt
The fract function in OpenCL does more than just return the fraction. It also writes the floor to the second argument. Which wasn't put in consideration. Instead, we use a simple `a - floor(a)` like the Math node. Reviewers: brecht Differential Revision: https://developer.blender.org/D5553
2019-08-21Shading: Add White Noise node.OmarSquircleArt
The White Noise node hashes the input and returns a random number in the range [0, 1]. The input can be a 1D, 2D, 3D, or a 4D vector. Reviewers: brecht, JacquesLucke Differential Revision: https://developer.blender.org/D5550
2019-08-21Shading: Add more operators to Vector Math node.OmarSquircleArt
Add Multiply, Divide, Project, Reflect, Distance, Length, Scale, Snap, Floor, Ceil, Modulo, Fraction, Absolute, Minimum, and Maximum operators to the Vector Math node. The Value output has been removed from operators whose output is a vector, and the other way around. All of those removals has been handled properly in versioning code. The patch doesn't include tests for the new operators. Tests will be added in a later patch. Reviewers: brecht, JacquesLucke Differential Revision: https://developer.blender.org/D5523
