2021-09-21Cycles: merge of cycles-x branch, a major update to the rendererBrecht Van Lommel
This includes much improved GPU rendering performance, viewport interactivity, new shadow catcher, revamped sampling settings, subsurface scattering anisotropy, new GPU volume sampling, improved PMJ sampling pattern, and more. Some features have also been removed or changed, breaking backwards compatibility. Including the removal of the OpenCL backend, for which alternatives are under development. Release notes and code docs: https://wiki.blender.org/wiki/Reference/Release_Notes/3.0/Cycles https://wiki.blender.org/wiki/Source/Render/Cycles Credits: * Sergey Sharybin * Brecht Van Lommel * Patrick Mours (OptiX backend) * Christophe Hery (subsurface scattering anisotropy) * William Leeson (PMJ sampling pattern) * Alaska (various fixes and tweaks) * Thomas Dinges (various fixes) For the full commit history, see the cycles-x branch. This squashes together all the changes since intermediate changes would often fail building or tests. Ref T87839, T87837, T87836 Fixes T90734, T89353, T80267, T80267, T77185, T69800

2021-09-11Geometry Nodes: Support modifier on curve objectsHans Goudey
With this commit, curve objects support the geometry nodes modifier. Curves objects now evaluate to `CurveEval` unless there was a previous implicit conversion (tessellating modifiers, mesh modifiers, or the settings in the curve "Geometry" panel). In the new code, curves are only considered to be the wire edges-- any generated surface is a mesh instead, stored in the evaluated geometry set. The consolidation of concepts mentioned above allows remove a lot of code that had to do with maintaining the `DispList` type temporarily for modifiers and rendering. Instead, render engines see a separate object for the mesh from the mesh geometry component, and when the curve object evaluates to a curve, the `CurveEval` is always used for drawing wire edges. However, currently the `DispList` type is still maintained and used as an intermediate step in implicit mesh conversion. In the future, more uses of it could be changed to use `CurveEval` and `Mesh` instead. This is mostly not changed behavior, it is just a formalization of existing logic after recent fixes for 2.8 versions last year and two years ago. Also, in the future more functionality can be converted to nodes, removing cases of implicit conversions. For more discussion on that topic, see T89676. The `use_fill_deform` option is removed. It has not worked properly since 2.62, and the choice for filling a curve before or after deformation will work much better and be clearer with a node system. Applying the geometry nodes modifier to generate a curve is not implemented with this commit, so applying the modifier won't work at all. This is a separate technical challenge, and should be solved in a separate step. Differential Revision: https://developer.blender.org/D11597
2021-09-08Asset: Dropping Material assets on material slot under mouse cursor.Jeroen Bakker
This patch allows dropping material assets from material slot under the mouse cursor. Before this change the material slot had to be hand-picked from the properties panel. For consistency it is chosen to do this in any shading mode as the tooltip shows what is exactly going to happen during release. The feature also works for other object types than Meshes as it uses the drawn surface on the GPU to detect the material slots. Performance of this patch has been tested with AMD GCN3.0 cards and are very responsive. Reviewed By: fclem, Severin Differential Revision: https://developer.blender.org/D12190
2021-09-06Geometry Nodes: support for geometry instancingJacques Lucke
Previously, the Point Instance node in geometry nodes could only instance existing objects or collections. The reason was that large parts of Blender worked under the assumption that objects are the main unit of instancing. Now we also want to instance geometry within an object, so a slightly larger refactor was necessary. This should not affect files that do not use the new kind of instances. The main change is a redefinition of what "instanced data" is. Now, an instances is a cow-object + object-data (the geometry). This can be nicely seen in `struct DupliObject`. This allows the same object to generate multiple geometries of different types which can be instanced individually. A nice side effect of this refactor is that having multiple geometry components is not a special case in the depsgraph object iterator anymore, because those components are integrated with the `DupliObject` system. Unfortunately, different systems that work with instances in Blender (e.g. render engines and exporters) often work under the assumption that objects are the main unit of instancing. So those have to be updated as well to be able to handle the new instances. This patch updates Cycles, EEVEE and other viewport engines. Exporters have not been updated yet. Some minimal (not master-ready) changes to update the obj and alembic exporters can be found in P2336 and P2335. Different file formats may want to handle these new instances in different ways. For users, the only thing that changed is that the Point Instance node now has a geometry mode. This also fixes T88454. Differential Revision: https://developer.blender.org/D11841

2021-08-23Cleanup: Move 'tris_per_mat' member out of 'MeshBufferCache'Germano Cavalcante
`MeshBufferCache` is a struct representing a list of buffers. As such, `GPUIndexBuf **tris_per_mat` is out of place as it does not represent one of the buffers in the list. In fact this member should be close to `GPUBatch **surface_per_mat` as they are related. The code for dependencies between buffer and batch had to be reworked as it relies on the member's position.

2021-07-21Draw Cache: extract tris in parallel rangesGermano Cavalcante
The `ibo.tris` extraction in multithread is currently only done if the mesh has only 1 material. Now we cache a map indicating the index of each polygon after sort and thus allow the extraction of tris with materials in multithreaded. As caching is a heavy operation and was already being performed in multi-thread for triangle offsets, no significant improvements are expected. The benefit will be much greater when we can skip updating the cache while transforming a geometry. **Profiling:** ||master:|PATCH: |---|---|---| |large_mesh_editing_materials:|Average: 13.855380 FPS|Average: 15.525684 FPS ||rdata 9ms iter 36ms (frame 71ms)|rdata 9ms iter 29ms (frame 64ms) |subdiv_mesh_final_only_materials:|Average: 28.113742 FPS|Average: 28.633599 FPS ||rdata 0ms iter 1ms (frame 36ms)|rdata 0ms iter 1ms (frame 35ms) 1.1x overall speedup Differential Revision: https://developer.blender.org/D11445
