2020-07-17Fix T77867: Link Duplicate Object crashes during batch creationJeroen Bakker
When using link duplicated objects it could happen that one object is calculating the GPUBuffers and the second object is marking these buffers invalid. This introduces threading issues. This patch fixes this by combining the surface and surface per material batches. Most likely the surface per material batches are used and when requested you will most likely need the surface batch for the depth tests and overlays. During tests it slightly improves performance as batches aren't thrown away without using it. After this patch we can add a quick path for meshes with one material and two materials. Alternative approaches that have been checked: - sync extraction per object: reduced performance to much (-15%) ({D8292}) - post checks: reduced the threading issues, but didn't solve it. - separating preparation and execution of the extraction ({D8312}) Reviewed By: Clément Foucault Differential Revision: https://developer.blender.org/D8329

2020-07-15PointCloud: Initial rendering support for WorkbenchClément Foucault
Also includes outline overlays. Removes the temp overlay drawing We make the geometry follow camera like billboards this uses less geometry. Currently we use half octahedron for now. Goal would be to use icospheres. This patch also optimize the case when pointcloud has uniform radius. However we should premultiply the radius prop by the default radius beforehand to avoid a multiplication on CPU. Using geometry instead of pseudo raytraced spheres is more scalable as we can render as low as 1 or 2 triangle to a full half sphere and can integrate easily in the render pipeline using a low amount of code.

2020-07-01DRW: optimize mesh data extractionCampbell Barton
Change extraction callbacks to take index ranges instead of calling them for each mesh element (poly, loop, vert & edge). This gives a minor overall performance gain in my tests, ~5% on average. Details: - Use typed parameter structs and macros for looping over elements. Without this, changes to these callbacks is time consuming as changes need to be made in many places. - Avoid iterating over polygon-loops when iterating over polygons is sufficient. - Simplify logic to access adjacent loops for faster line extraction. - Rename 'loop' iterators to 'poly' (as they take polygon ranges) the iterator callbacks can operator on either polygon or loop data. - Use term 'last' for the last index (inclusive), use 'end' when this value (not inclusive).

2020-06-23Sculpt Vertex Colors: Initial implementationPablo Dobarro
Sculpt Vertex Colors is a painting system that runs inside sculpt mode, reusing all its tools and optimizations. This provides much better performance, easier to maintain code and more advanced features (new brush engine, filters, symmetry options, masks and face sets compatibility...). This is also the initial step for future features like vertex painting in Multires and brushes that can sculpt and paint at the same time. This commit includes: - SCULPT_UNDO_COLOR for undo support in sculpt mode - SCULPT_UPDATE_COLOR and PBVH flags and rendering - Sculpt Color API functions - Sculpt capability for sculpt tools (only enabled in the Paint Brush for now) - Rendering support in workbench (default to Sculpt Vertex Colors except in Vertex Paint) - Conversion operator between MPropCol (Sculpt Vertex Colors) and MLoopCol (Vertex Paint) - Remesher reprojection in the Voxel Remehser - Paint Brush and Smear Brush with color smoothing in alt-smooth mode - Parameters for the new brush engine (density, opacity, flow, wet paint mixing, tip scale) implemented in Sculpt Vertex Colors - Color Filter - Color picker (uses S shortcut, replaces smooth) - Color selector in the top bar Reviewed By: brecht Maniphest Tasks: T72866 Differential Revision: https://developer.blender.org/D5975
2020-06-23Fix T77893: Crash drawmanager threading custom dataJeroen Bakker
Tangent normals were temporarily saved in the original given layers but the typeinfo wasn't updated. This lead to several issues since we changed the threading of the mesh extraction. This patch stores the tangent normals in a temporary custom data on the stack this way the typemap doesn't need to be updated. Still need to run the tests for an hour to see if it is fixed Reviewed By: Clément Foucault, Philipp Oeser Differential Revision: https://developer.blender.org/D8095
2020-06-23EEVEE: Motion Blur: Add accumulation motion blur for better precisionClément Foucault
This revisit the render pipeline to support time slicing for better motion blur. We support accumulation with or without the Post-process motion blur. If using the post-process, we reuse last step next motion data to avoid another scene reevaluation. This also adds support for hair motion blur which is handled in a similar way as mesh motion blur. The total number of samples is distributed evenly accross all timesteps to avoid sampling weighting issues. For this reason, the sample count is (internally) rounded up to the next multiple of the step count. Only FX Motion BLur: {F8632258} FX Motion Blur + 4 time steps: {F8632260} FX Motion Blur + 32 time steps: {F8632261} Reviewed By: jbakker Differential Revision: https://developer.blender.org/D8079

2020-06-19EEEVEE: Object Motion Blur: Initial ImplementationClément Foucault
This adds object motion blur vectors for EEVEE as well as better noise reduction for it. For TAA reprojection we just compute the motion vector on the fly based on camera motion and depth buffer. This makes possible to store another motion vector only for the blurring which is not useful for TAA history fetching. Motion Data is saved per object & per geometry if using deformation blur. We support deformation motion blur by saving previous VBO and modifying the actual GPUBatch for the geometry to include theses VBOs. We store Previous and Next frame motion in the same motion vector buffer (RG for prev and BA for next). This makes non linear motion blur (like rotating objects) less prone to outward/inward blur. We also improve the motion blur post process to expand outside the objects border. We use a tile base approach and the max size of the blur is set via a new render setting. We use a background reconstruction method that needs another setting (Background Separation). Sampling is done using a fixed 8 dithered samples per direction. The final render samples will clear the noise like other stochastic effects. One caveat is that hair particles are not yet supported. Support will come in another patch.
