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
2019-09-09Shading: Extend Musgrave node to other dimensions.OmarSquircleArt

Fix issue in latest patch and assure derivatives calculation is correct on all GPU.
2019-09-06Fix T68950: Adding lots of edge loops to cylinder produces a crashHuseyin Karakullukcu
Instead of fixed size, `IMM_BUFFER_SIZE` is adjustable now. The internal buffer can expand if there is a need a bigger buffer. All other behaviors are still the same. Reviewed By: fclem, #gpu_viewport Differential Revision: https://developer.blender.org/D5570
2019-09-06Eevee: Use manual derivatives for better quality bump.Clément Foucault
We basically duplicate the height map branch plugged into the bump node, and tag each node in each branch as dx/dy/ref using `branch_tag`. Then we add a one pixel offset on the texture coordinates if the node is tagged as dx or dy. The dx/dy branches are plugged into (new) hidden sockets on the bump node. This match cycles bump better but have a performance impact. Also, complex nodetrees can now become instruction limited and not compile anymore.

`noise_turbulence` was renamed to `fractal_noise`. Reviewers: brecht Differential Revision: https://developer.blender.org/D5691
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. Reviewers: brecht, JacquesLucke Differential Revision: https://developer.blender.org/D5560
2019-09-04Fix T63755: Area Stretching OverlayJeroen Bakker
Support for UV Stretching overlay during multi object editing. The VBO now holds the ratios per fase. In the shader these ratios will be compared against the global ratios. The global rations are created from all selected objects. The current implementation does not fit well with the draw module. The plan is to move the drawing of other spaces towards the draw manager what leads to a better fit. Currently the details on this solution is unclear but this requirement will become an attentionpoint in the future design.

2019-08-30GPU: Split gpu_shader_material into multiple files.OmarSquircleArt
This patch continue the efforts to split the `gpu_shader_material` file started in D5569. Dependency resolution is now recursive. Each shading node gets its own file. Additionally, some utility files are added to be shared between files, like `math_util`, `color_util`, and `hash`. Some files are always included because they may be used in the execution function, like `world_normals`. Some glsl functions appeared to be unused, so they were removed, like `output_node`, `bits_to_01`, and `exp_blender`. Other functions have been renamed to be more general and get used as utils, like `texco_norm` which became `vector_normalize`. A lot of the opengl tests fails, but those same tests also fail in master, so this is probably unrelated to this patch. Reviewers: brecht Differential Revision: https://developer.blender.org/D5616

2019-08-27Workbench: Specular Highlighting for MatCapsJeroen Bakker
With Blender 2.80 we introduced a more flexible matcap system. One change we did was to multiply the matcap with the base color that was shaded. As matcaps contains diffuse and specular lighting in a single texture this lead to rendering artifacts. Artists were complaining that everything looked to metalic. We now support a separate `diffuse` and `specular` pass for matcaps. `shaded_color = diffuse_light * base_color + specular_light` For matcaps to support this feature they need to be multilayer openexr files with 2 renderpasses (named `diffuse` and `specular`). In the future we can change this to first pass/second pass in stead of this naming convention. Reviewed By: fclem, brecht Differential Revision: https://developer.blender.org/D5335

2019-08-26GPU: add mechanism for splitting up big gpu_shader_material.glsl fileBrecht Van Lommel
Compiling this big file for every Eevee material is bad for performance, and now that we are adding more nodes it gets worse. This patch adds a simple mechanism to split up that file, and use only the parts used by shader nodes. When a function is used by GPU_link, we detect which GLSL file it came from and use it in GLSL code generation automatically. Dependencies between GLSL files are manually specified, and function names must be unique across all GLSL files. Most of the actual splitting up will be done in later commits.

2019-08-22Shading: Add object color to Object Info node.OmarSquircleArt
The object color property is added as an additional output in the Object Info node. Reviewers: brecht Differential Revision: https://developer.blender.org/D5554
2019-08-22Nodes: Support for socket shapes other than circleCharlie Jolly
Previously there was already "draw_shape" property, but it was doing nothing. This commit renames the property to "display_shape". Furthermore, different shapes like SQUARE and DIAMOND are supported now. Currently, the shapes are drawn using the shader that also draws keyframes. In the future we might want to separate this. The new shapes are not used anywhere yet, but they can be used by addon developers and will probably be useful when we want to support different kinds node systems later. For example, different shapes can be used to distinguish between data and control flow. Differential Revision: https://developer.blender.org/D2829

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

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.

This reduces the risks of hash collision while maintaining a small number of character per attrib.
2019-08-15Mesh Batch Cache: Split UV an tangent into 2 distinct VBOsClément Foucault
This is done because they don't have the same update frequency. UV can be persistent even on geometry update (ex: skinned object) but tangents can change if the normals change. Also the name buffer per vbo was too small to contain all names.

2019-08-14Mesh Batch Cache: Refactor + MultithreadClément Foucault
For clarity sake, the batch cache now uses exclusively per Loop attributes. While this is a bit of a waste of VRAM (for the few case where per vert attribs are enough) it reduces the complexity and amount of overall VBO to update in general situations. This patch also makes the VertexBuffers filling multithreaded. This make the update of dense meshes a bit faster. The main bottleneck is the IndexBuffers update which cannot be multithreaded efficiently (have to increment a counter and/or do a final sorting pass). We introduce the concept of "extract" functions/step. All extract functions are executed in one thread each and if possible, using multiple thread for looping over all elements.
