2020-07-30EEVEE: GLSL refactor/cleanupClément Foucault
- add the use of DRWShaderLibrary to EEVEE's glsl codebase to reduce code complexity and duplication. - split bsdf_common_lib.glsl into multiple sub library which are now shared with other engines. - the surface shader code is now more organised and have its own files. - change default world to use a material nodetree and make lookdev shader more clear.

2020-06-24Fix T78215 EEVEE: incorrect Render Passes results when using motion blurClément Foucault
This was caused by a missing DRWPass initialization. Now we create the passes for every timestep but avoid clearing the buffer after the first sample.
2020-06-02EEVEE: Refactor of eevee_material.cClément Foucault
These are the modifications: -With DRW modification we reduce the number of passes we need to populate. -Rename passes for consistent naming. -Reduce complexity in code compilation -Cleanup how renderpass accumulation passes are setup, using pass instances. -Make sculpt mode compatible with shadows -Make hair passes compatible with SSS -Error shader and lookdev materials now use standalone materials. -Support default shader (world and material) using a default nodetree internally. -Change BLEND_CLIP to be emulated by gpu nodetree. Making less shader variations. -Use BLI_memblock for cache memory allocation. -Renderpasses are handled by switching a UBO ref bind. One major hack in this patch is the use of modified pointer as ghash keys. This rely on the assumption that the keys will never overlap because the number of options per key will never be bigger than the pointed struct. The use of one single nodetree to support default material is also a bit hacky since it won't support concurent usage of this nodetree. (see EEVEE_shader_default_surface_nodetree) Another change is that objects with shader errors now appear solid magenta instead of shaded magenta. This is only because of code reuse purpose but could be changed if really needed. Reviewed By: jbakker Differential Revision: https://developer.blender.org/D7642
2020-06-02GPU: Texture: Replace internal sampler state by explicit state objectClément Foucault

2020-03-18Volumes: add render settings for volume datablockBrecht Van Lommel
* Space: volume density and step size in object or world space * Step Size: override automatic step size * Clipping: values below this are ignored for tighter volume bounds The last two are Cycles only currently. Ref T73201
2020-03-18Objects: Eevee and workbench rendering of new Volume, Hair, PointCloudBrecht Van Lommel
Only the volume drawing part is really finished and exposed to the user. Hair plugs into the existing hair rendering code and is fairly straightforward. The pointcloud drawing is a hack using overlays rather than Eevee and workbench. The most tricky part for volume rendering is the case where each volume grid has a different transform, which requires an additional matrix in the shader and non-trivial logic in Eevee volume drawing. In the common case were all the transforms match we don't use the additional per-grid matrix in the shader. Ref T73201, T68981 Differential Revision: https://developer.blender.org/D6955
2020-03-14Fix T73921: Eevee volume render test memory leak in MantaflowSebastián Barschkis
Fixed memory leak that showed up after the original issue (crash) had been fixed in 93ac4709ebe8. The fix ensures that light cache bakes free up GPU smoke textures and the smoke domain list correctly. This commit also removes the workaround (f3a33a92987f) that disabled light cache bakes for fluid objects.
2020-03-11EEVEE: Replace octahedron reflection probe by cubemap arrayClément Foucault
We implement cubemap array support for EEVEE's lightcache reflection probes. This removes stretched texels and bottom hemisphere seams artifacts caused by the octahedral projection previously used. This introduce versioning code for the lightcache which will discard any lightcache version that is not compatible. Differential Revision: https://developer.blender.org/D7066
2020-03-11Eevee: internal support for arbitrary number of volume gridsBrecht Van Lommel
This has no user visible impact yet since smoke volumes only support a fixed set of attributes, but will become important with the new volume object. For GPU shader compilation, volume grids are now handled separately from image textures. They are somewhere between a vertex attribute and an image texture, basically an attribute that is stored as a texture. Differential Revision: https://developer.blender.org/D6952
2020-03-11Smoke: put density/color in separate textures, fixes for workbench shaderBrecht Van Lommel
This is more in line with standard grids and means we don't have to make many special exceptions in the upcoming change for arbitrary number of volume grids support in Eevee. The workbench shader was also changed to fix bugs where squared density was used, and the smoke color would affect the density so that black smoke would be invisible. This can change the look of smoke in workbench significantly. When using the color grid when smoke has a constant color, the color grid will no longer be premultiplied by the density. If the color is constant we want to be able not to store a grid at all. This breaks one test for Cycles and Eevee, but the setup in that test using a color without density does not make sense. It suffers from artifacts since the unpremultiplied color grid by itself will not have smooth boundaries. Differential Revision: https://developer.blender.org/D6951
2020-02-26Cleanup: don't set renderpass_block twice for volumesBrecht Van Lommel
2020-02-21EEVEE: Render PassesJeroen Bakker
This patch adds new render passes to EEVEE. These passes include: * Emission * Diffuse Light * Diffuse Color * Glossy Light * Glossy Color * Environment * Volume Scattering * Volume Transmission * Bloom * Shadow With these passes it will be possible to use EEVEE effectively for compositing. During development we kept a close eye on how to get similar results compared to cycles render passes there are some differences that are related to how EEVEE works. For EEVEE we combined the passes to `Diffuse` and `Specular`. There are no transmittance or sss passes anymore. Cycles will be changed accordingly. Cycles volume transmittance is added to multiple surface col passes. For EEVEE we left the volume transmittance as a separate pass. Known Limitations * All materials that use alpha blending will not be rendered in the render passes. Other transparency modes are supported. * More GPU memory is required to store the render passes. When rendering a HD image with all render passes enabled at max extra 570MB GPU memory is required. Implementation Details An overview of render passes have been described in https://wiki.blender.org/wiki/Source/Render/EEVEE/RenderPasses Future Developments * In this implementation the materials are re-rendered for Diffuse/Glossy and Emission passes. We could use multi target rendering to improve the render speed. * Other passes can be added later * Don't render material based passes when only requesting AO or Shadow. * Add more passes to the system. These could include Cryptomatte, AOV's, Vector, ObjectID, MaterialID, UV. Reviewed By: Clément Foucault Differential Revision: https://developer.blender.org/D6331
