2020-10-23Cleanup: remove redundant assignment in previous bugfixBrecht Van Lommel
2020-10-23Fix use of uninitialized line/polygon smooth variables in GPU stateBrecht Van Lommel
Found by valgrind, unclear if this caused an actual bug.
2020-10-23Fix T73793 Walk navigation crosshair gets hidden behind objectsClément Foucault
This was reintroduced by the wide line emulation workaround.
2020-10-22EEVEE: Principle BSDF: Use multi-scatter switch for the glass variantClément Foucault
This avoid strange discrepency between the general purpose variant and the specialized glass variant which did not have a way to turn multi-scatter off.
2020-10-20EEVEE: ShaderToRGB alpha inversedJeroen Bakker
The alpha out socket output the average transmittance, not the alpha. This patch will convert the transmittance to alpha. Found during research of T80919; Issue introduced when `Closure.opacity` was migrated to `Closure.transmittance`.

2020-10-09GPU: Add more safeguard for BGL callsClément Foucault
This makes sure no BGL call before window drawing locks the GPUState.
2020-10-09BGL: fix issues with addons using BGL at startupClément Foucault
This was an issue for Cycles. This also makes the `GPU_bgl*` functions less fragile by checking for null pointers.

2020-10-09GPU: Fix NOT ~ operator for eGPUSamplerStateAnkit Meel
The real maximum was `GPU_SAMPLER_ICON`, not `GPU_SAMPLER_REPEAT`, my bad. {rBa31a87f8943aa40} Move `GPU_SAMPLER_MAX` out of the enum since it's used as an `int` at many places. Also, the macro `ENUM_OPERATORS` needs a maximum, and this enumerator cannot be used as the argument of that macro. It creates wrong values in the `~` NOT operator. Thanks @deadpin for catching this.

2020-10-08Fix T80974 GPU: Wide Line emulation shader does not always worksClément Foucault
This was caused by points well behind the near clip making the computation of the width wrong. The fix is to clip the line to the near clip plane.
2020-10-08T81340: UBSan: load of value .. not valid for GPU enum typeAnkit Meel
The underlying type of the enum cannot be fixed here due to its usage in C code. All the values possible in the width of the underlying type are not valid for an enum. Only 0 to (2*max - 1) if all enumerators are unsigned. So the macro asks for the biggest value among the //listed// ones. If any enumerator C is set to say `A|B`, then C would be the maximum. (2*max-1) is used as the mask. The warnings (for each enum modified in this commit): GPU_vertex_buffer.h:43:1: runtime error: load of value 4294967291 which is not a valid value for type 'GPUVertBufStatus' https://github.com/llvm/llvm-project/commit/1c2c9867 Ref T81340 Reviewed By: fclem Differential Revision: https://developer.blender.org/D9067
2020-10-08Revert "BGL: Workaround broken bgl usage caused by GPU refactor"Clément Foucault
This reverts commit f12b0373f322b710b9fa5cebb67bdf363ff90e9f.
2020-10-08BGL: Workaround broken bgl usage caused by GPU refactorClément Foucault
This directly adress the issues caused by rB536c2e0ec916. Since the state tracking is done at a lower level, using the bgl functions needs to be safegarded by the state manager. The current workaround is to bypass `apply_state` when inside a callback that used a `bgl` function. Related to T80730. This fix T81003. Also this fix the default blend equation for callbacks. Fixes T80169 T81289.
2020-10-07GPU: Fix assert when using gpu workaround and SSS + light renderpassClément Foucault
This path makes use of more framebuffers when using the gpu workarounds. Increase the MAX FBO attachments per texture. Maybe we could use a growing vector in the future.
2020-10-07GPU: Avoid blit operation modifying the wrong framebuffer during restoreClément Foucault
At the end of `GPU_framebuffer_blit` when `prev_fb->bind(true);` is called, the `context_->active_fb` was not in sync and lead to the wrong framebuffer being modified by bind function. This fix T81055 SSS light is missing from the diffuse light render pass

2020-09-25Fix T80998: DDS Image files are not displayed correctlyJeroen Bakker
Blender 2.91 only. Due to recent refactoring the compressed texture formats missed the conversion to its GL counterpart.
2020-09-22Fix T81002: Images drawn with the Python gpu module no longer draw on top in ↵Jeroen Bakker
the Image Editor Since {D8234} the image editor is drawn using a depth buffer. When using `draw_texture_2d` the image is drawn using the 2D_IMAGE shader. inside the vertex buffer the image was pushed to the background. This was introduced by {648924333234} what seems to be out dated as we have done several overhauls in this area. (workbench refactor, overlay engine refactor, color management pipeline). This patch removes the pushing of the image to the background.

2020-09-19EEVEE: Fix Missing GGX multi-scattering on Glass BSDFClément Foucault
Oversight that should have been in rB6f3c279d9e70
2020-09-19EEVEE: Add support for GGX Multi-scatterClément Foucault
Based on http://jcgt.org/published/0008/01/03/ This is a simple trick that does *not* have a huge performance impact but does work pretty well. It just modifies the Fresnel term to account for the multibounce energy loss (coloration). However this makes the shader variations count double. To avoid this we use a uniform and pass the multiscatter use flag inside the sign of f90. This is a bit hacky but avoids many code duplication. This uses the simplification proposed by McAuley in A Journey Through Implementing Multiscattering BRDFs and Area Lights This does not handle area light differently than the IBL case but that's already an issue in current implementation. This is related to T68460. Reviewed By: brecht Differential Revision: https://developer.blender.org/D8912

2020-09-18GPUShader: Fix wide line emulation with flat color interpolation.Clément Foucault
This was causing flashing colors in the node editor grid. This is because in some cases the flat color is only set on the provoking vertex which is the last of the primitive by default.
2020-09-18GPUImmediate: Add system wide workaround for wide lineClément Foucault
This makes wide line supported on MacOS and other implementation that does not support wide line by default. This workaround works for all Line types but only if using one of the 5 default shaders. The workaround is completely isolated and invisible to the outside. It has no side effect. Note: This does not affect the GPUBatch drawing.
