2020-06-24Fix T77672 EEVEE: Reflections with reflection plane broken (regression)Clément Foucault
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

2020-03-11EEVEE: 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
2020-03-09Cleanup: Replace ABS/SQUARE/CUBE with function callsSergey Sharybin
While it might be handy to have type-less functionality which is similar to how C++ math is implemented it can not be easily achieved with just preprocessor in a way which does not have side-effects on wrong usage. There macros where often used on a non-trivial expression, and there was at least one usage where it was causing an actual side effect/bug on Windows (see change around square_f(sh[index++]) in studiolight.c). For such cases it is handy to have a function which is guaranteed to have zero side-effects. The motivation behind actually removing the macros is that there is already a way to do similar calculation. Also, not having such macros is a way to guarantee that its usage is not changed in a way which have side-effects and that it's not used as an inspiration for cases where it should not be used.

2020-02-25EEVEE: Lookdev: Add support for partially blurred backgroundClément Foucault
This is using the GGX probe as background. This has the drawback of having the resolution choosed in the indirect lighting setting. The blurring is not really high-quality. The pros is that it has a simple implementation and is fast to evaluate. This patch also fades the background alpha to make overlay engine draw the default background color in the correct color space. Removing one colorspace hack.

2020-02-25Cleanup: EEVEE: Use log2_floor_uClément Foucault
2020-02-25EEVEE: Fix seams in reflection cubemap on low roughnessClément Foucault
This was caused by the texture size not being power of 2. Thus the padding applied to the base LOD did not match the highest mipmaps.
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

There is no reason to disable the refraction on the first sample like SSR does. This was caussing issues when rendering.

This cleans up a bit of duplicated code and some confusion about what was culled and what wasn't. Now everything is culled based on the given object pointer. If the object pointer is NULL there is no culling performed.

2019-05-14DRW: Refactor: Use DRWCall to accumulate per instance attributesClément Foucault
This is a big change that cleanup a lot of confusing code. - The instancing/batching data buffer distribution in draw_instance_data.c. - The selection & drawing code in draw_manager_exec.c - Prety much every non-meshes object drawing (object_mode.c). Most of the changes are just renaming but there still a chance a typo might have sneek through. The Batching/Instancing Shading groups are replace by DRWCallBuffers. This is cleaner and conceptually more in line with what a DRWShadingGroup should be. There is still some little confusion in draw_common.c where some function takes shgroup as input and some don't.

2019-03-13Fix T60902 Eevee: Environment texture partially visible on transp. renderClément Foucault
This was due to environement not being rendered with alpha blending. So color was still written and contributed to the final render color. Now we multiply by background alpha so that it removes any background pixels intensity. For this reason this made the (incorrect) final premult unecessary.
2019-03-12Eevee: Planar Ref.: Invert view matrix to remove triangle front face flipClément Foucault
This was the cause of some issue with normal mapping. This way is cleaner since it does not modify the state of the drawcalls and other ad-hoc solutions to fix the problems down the road. Unfortunately, it does require to fix every sampling coordinate for this texture. Fix T62215: flipped normals in reflection plane

BF-admins agree to remove header information that isn't useful, to reduce noise. - BEGIN/END license blocks Developers should add non license comments as separate comment blocks. No need for separator text. - Contributors This is often invalid, outdated or misleading especially when splitting files. It's more useful to git-blame to find out who has developed the code. See P901 for script to perform these edits.
