2020-12-04Cycles: Add support for shader raytracing in OptiXPatrick Mours
Support for the AO and bevel shader nodes requires calling "optixTrace" from within the shading VM, which is only allowed from inlined functions to the raygen program or callables. This patch therefore converts the shading VM to use direct callables to make it work. To prevent performance regressions a separate kernel module is compiled and used for this purpose.

2020-11-04Cycles API: encapsulate Node socket membersKévin Dietrich
This encapsulates Node socket members behind a set of specific methods; as such it is no longer possible to directly access Node class members from exporters and parts of Cycles. The methods are defined via the NODE_SOCKET_API macros in `graph/ node.h`, and are for getting or setting a specific socket's value, as well as querying or modifying the state of its update flag. The setters will check whether the value has changed and tag the socket as modified appropriately. This will let us know how a Node has changed and what to update, which is the first concrete step toward a more granular scene update system. Since the setters will tag the Node sockets as modified when passed different data, this patch also removes the various modified methods on Nodes in favor of Node::is_modified which checks the sockets' update flags status.

2020-11-03Cycles: add support for BVH refit in OptiXKévin Dietrich
This avoids recomputing the BVH for geometries that do not have changes in topology but whose vertices are modified (like a simple character animation), and gives up to 40% speedup for BVH building. This is only available for viewport renders at the moment. Reviewed By: pmoursnv, brecht Differential Revision: https://developer.blender.org/D9353
2020-10-31Cycles: Implement tile stealing to improve CPU+GPU rendering performanceLukas Stockner
While Cycles already supports using both CPU and GPU at the same time, there currently is a large problem with it: Since the CPU grabs one tile per thread, at the end of the render the GPU runs out of new work but the CPU still needs quite some time to finish its current times. Having smaller tiles helps somewhat, but especially OpenCL rendering tends to lose performance with smaller tiles. Therefore, this commit adds support for tile stealing: When a GPU device runs out of new tiles, it can signal the CPU to release one of its tiles. This way, at the end of the render, the GPU quickly finishes the remaining tiles instead of having to wait for the CPU. Thanks to AMD for sponsoring this work!

2020-10-29Cycles: abort rendering when --cycles-device not foundBrecht Van Lommel
Rather than just printing a message and falling back to the CPU. For render farms it's better to avoid a potentially slow render on the CPU if the intent was to render on the GPU. Ref T82193, D9086

2020-10-05Cycles: Add NanoVDB support for rendering volumesPatrick Mours
NanoVDB is a platform-independent sparse volume data structure that makes it possible to use OpenVDB volumes on the GPU. This patch uses it for volume rendering in Cycles, replacing the previous usage of dense 3D textures. Since it has a big impact on memory usage and performance and changes the OpenVDB branch used for the rest of Blender as well, this is not enabled by default yet, which will happen only after 2.82 was branched off. To enable it, build both dependencies and Blender itself with the "WITH_NANOVDB" CMake option. Reviewed By: brecht Differential Revision: https://developer.blender.org/D8794

2020-09-15Fix T80477: Crash when rendering with Embree but denoising with OptiXPatrick Mours
Commit 009971ba7adc9603b90e9bf99b6b6d53eeae6c3a changed it so Cycles creates a separate Embree device for each Cycles device, but missed the multi-device case. A multi-device with Embree BVH can occur when CPU rendering is used with OptiX denoising and BVH creation then failed to get a valid pointer to the Embree device, which crashed. This fixes that by providing the correct device pointer in the multi-device case as well.

2020-08-19Cycles : add a Volume Geometry NodeKévin Dietrich
This splits the volume related data (properties for rendering and attributes) of the Mesh node into a new `Volume` node type. This `Volume` node derives from the `Mesh` class since we generate a mesh for the bounds of the volume, as such we can safely work on `Volumes` as if they were `Meshes`, e.g. for BVH creation. However such code should still check for the geometry type of the object to be `MESH` or `VOLUME` which may be bug prone if this is forgotten. This is part of T79131.

one is found This patch changes the discovery of pre-compiled kernels, to look for any PTX, even if it does not match the current architecture version exactly. It works because the driver can JIT-compile PTX generated for architectures less than or equal to the current one. This e.g. makes it possible to render on a new GPU architecture even if no pre-compiled binary kernel was distributed for it as part of the Blender installation.

2020-07-10Cycles: support OpenImageDenoise in final rendersBrecht Van Lommel
Performance is not great currently due to the API not seeming to support efficient denoising of multiple tiles at the same time. So in many cases only one or a few threads will actually be denoising at the same time. In renders with many samples this is not a big problem, but for faster renders it's a signficant overhead. We should try to optimize this still, possibly by batching denoising of a bigger neighborhood of multiple tiles at once.

2020-07-07Cycles: Add support for native OptiX curve primitivePatrick Mours
This patch adds support for the curve primitive from OptiX to Cycles. It's currently hidden behind a debug option, since there can be some slight rendering differences still (because no backface culling is performed and something seems off with endcaps). The curve primitive was added with the OptiX 7.1 SDK and requires a r450 driver or newer, so this also updates the codebase to be able to build with the new SDK.

2020-06-24Cycles: add Intel OpenImageDenoise support for viewport denoisingBrecht Van Lommel
Compared to Optix denoise, this is usually slower since there is no GPU acceleration. Some optimizations may still be possible, in avoid copies to the GPU and/or denoising less often. The main thing is that this adds viewport denoising support for computers without an NVIDIA GPU (as long as the CPU supports SSE 4.1, which is nearly all of them). Ref T76259
2020-06-24Cycles: add denoising settings to the render propertiesBrecht Van Lommel
Enabling render and viewport denoising is now both done from the render properties. View layers still can individually be enabled/disabled for denoising and have their own denoising parameters. Note that the denoising engine also affects how denoising data passes are output even if no denoising happens on the render itself, to make the passes compatible with the engine. This includes internal refactoring for how denoising parameters are passed along, trying to avoid code duplication and unclear naming. Ref T76259
2020-06-22Cycles: port curve-ray intersection from Embree for use in Cycles GPUBrecht Van Lommel
This keeps render results compatible for combined CPU + GPU rendering. Peformance and quality primitives is quite different than before. There are now two options: * Rounded Ribbon: render hair as flat ribbon with (fake) rounded normals, for fast rendering. Hair curves are subdivided with a fixed number of user specified subdivisions. This gives relatively good results, especially when used with the Principled Hair BSDF and hair viewed from a typical distance. There are artifacts when viewed closed up, though this was also the case with all previous primitives (but different ones). * 3D Curve: render hair as 3D curve, for accurate results when viewing hair close up. This automatically subdivides the curve until it is smooth. This gives higher quality than any of the previous primitives, but does come at a performance cost and is somewhat slower than our previous Thick curves. The main problem here is performance. For CPU and OpenCL rendering performance seems usually quite close or better for similar quality results. However for CUDA and Optix, performance of 3D curve intersection is problematic, with e.g. 1.45x longer render time in Koro (though there is no equivalent quality and rounded ribbons seem fine for that scene). Any help or ideas to optimize this are welcome. Ref T73778 Depends on D8012 Maniphest Tasks: T73778 Differential Revision: https://developer.blender.org/D8013

2020-06-22Cycles: use TBB for task pools and task schedulerBrecht Van Lommel
No significant performance improvement is expected, but it means we have a single thread pool throughout Blender. And it should make adding more parallellization in the future easier. After previous refactoring commits this is basically a drop-in replacement. One difference is that the task pool had a mechanism for scheduling tasks to the front of the queue to minimize memory usage. TBB has a smarter algorithm to balance depth-first and breadth-first scheduling of tasks and we assume that removes the need to manually provide hints to the scheduler. Fixes T77533
