Follow our code style for doxygen sections.
2020-10-23Fix T81942 EEVEE: Reflection Plane glitch with low clip distancesClément Foucault
This was happening because the raytrace was not even being performed due to the tracing line being too small after frustum clipping.
2020-10-22DRW: Fix custom engine not being BGL safeClément Foucault
This was caused by unprotected drawing callbacks. As of 2.91, we require that all python callbacks used for drawing needs to be safeguarded by `GPU_bgl_end()` to end the state tracking override.
2020-10-22Fix T77658 EEVEE: Reflection Plane partially missing reflectionsClément Foucault
The degenerate line workaround was ill defined.
2020-10-21EEVEE: Screen Space Reflection: Improve contact reflectionsClément Foucault
This patch helps the case of intricate reflections where the ray does not travel far before intersecting the geometry. In these cases there could be false negative exclusion of the ray caused by the backface rejection threshold.
2020-10-21EEVEE: Screen Space Raytrace: Fix unreported banding artifactsClément Foucault
The artifact manifested as lines of different values caused by faillure to trace the depth buffer correctly. Adding a ad-hoc value to the step size to mitigate the issue.
2020-10-21DrawManager: Adding Custom Render PassesJeroen Bakker
Currently render passes in the draw manager (eevee) must be predefined in the render result. This patch would ask the render engine for the render passes it needs, and create these as a preparation step during rendering. This allows any draw engine to define more complex render passes setup. Render passes can only be added before the call to `RE_engine_begin_result`. `RE_engine_begin_result` makes a full copy of the render passes. During rendering the render engines renders to the duplicated passes. `RE_engine_end_result` syncs the data back to the original render passes, but only if the passes existed in the original render result. Currently we work-around this issue by registering the passes in `render_result_new`. This is legacy blender internal structure and should be avoided. With upcoming projects (AOV/Cryptomatte) it becomes a bit of a mess as we are extending legacy code to support new features. This patch allows us to let each draw engine register their own render passes at render time (similar to cycles and other render engines). In the future we could get rid of legacy render passes registration in render_result_new. Reviewed By: Clément Foucault Differential Revision: https://developer.blender.org/D9088
2020-10-20EEVEE: Screen Space Reflection: Improve self intersection cases.Clément Foucault
This patch fix most self intersection comming from reflection rays. We regenerate the ray if it goes below the shading normal (should be the geometric normal but we have no access to it here). Also add the same precision based bias we use for contact shadows. This fix T81105 Eevee SSR quality regression in 2.91 alpha
2020-10-20EEVEE: Screen Space Reflection: Fix undefined behavior with invalid LODClément Foucault
Some issues happened because the lod can become negative in some cases. Also avoid sampling LOD with interpolation (floor).
2020-10-20DRW: Disable anisotropic filtering on utility texturesClément Foucault
Anisotropic filter may result in incorrect algorithm. This only affects util textures (not Image datablocks gpu textures).
2020-10-20Volumes: simplify volumes in modifiers or on loadJacques Lucke
This changes how the simplify volumes setting works. Before, it only affeted viewport rendering. This was an issue, because all internal computations would still have to happen on the high resolution volumes. With this patch, the simplify setting already affects file loading and procedural generation of volumes. Rendering does not have to care about the simplify option anymore, it just gets the correct simplified version from the depsgraph.

2020-10-19Fix T81167: Texture Painting with Paint mask enabled, (de)selecting faces ↵Jeroen Bakker
causes a mess with texture slots Issue caused by {9582797d4b50} in b2.90. The surface per material used an index buffer owned by the batch. These index buffers are created at the same time the surface tris index buffer was created. When a material per batch buffer was invalidated it used the surface tris index buffer rendering all materials on all surfaces making the last draw command render succeed. This patch stores the surface tris per material in the cache so they can be reused. There is also no need to use the `saved_elem_ranges` anymore as they are now part of the cache. The ugly bit of the implementation is that in `extract_tris_finish` the MeshBufferCache is retrieved. But as this part was already documented as a hack and it is something that is only used for final meshes. Other solutions would impact performance or made the fix not condensed (passing parameters that shouldn't be used).

2020-10-17Fix T81761: EEVEE enabled AO pass affects render resultDalai Felinto
This was a regression introduced on 68651534c263.
2020-10-16EEVEE: SSR: Fix unreported smoothstep instability when border factor is 0Clément Foucault
From the GLSL documentation: `Results are undefined if edge0 ≥ edge1.` This is the case without this patch.
2020-10-14Fix T81633 Workbench: TAA never resolve when enabling both X-Ray and cavityClément Foucault
This was caused by a wrong flag equality check when in xray mode because the xray mode was masking the effect option flags that are not supported in this mode. This means the never passed and the TAA was reset before every redraw, leading to infinite rendering.

2020-10-07Fix T81254: Incorrect calculation of EEVEE Transmittance VolumetricsJeroen Bakker
Regular rendering uses a custom blend mode, but render passes renders to 2 separate textures. This wasn't configured correctly inside the fragment shaders.

2020-10-07UV/Image Editor: Overlay PopoverJeroen Bakker
The overlay options in the image/uv editor is hidden in side panels and menus. Sometimes this panel is even hidden, while still useful. The goal of this task is to introduce an overlay pop-over just like the overlay-popover of the 3d viewport. Popover has * UV Stretching (only available in the UV mode, when active object mode is a mesh and in OB_EDIT mode) * Display As (only available in the UV mode, when active object mode is a mesh and in OB_EDIT mode) * Show Modified (only available in the UV mode, when active object mode is a mesh and in OB_EDIT mode) * Show UV Edges (including opacity slider; available UV, View, Paint, when active object mode is a mesh and in OB_EDIT mode) * Udim tiles when no image is available. Like the 3d viewport, there will be a editor toggle to enable/disable the overlays For compatibility reasons the RNA properties are added to both the `SpaceImage.uv_editor` amd `SpaceImage.overlay`. On DNA level they are still stored in the SpaceImage. only new properties are added to the SpaceImageOverlay struct. During the next major release we could remove these options from `SpaceImage.uv_editor`. This should be noted in the Python section of release notes.

This was introduced in 6c9ec1c893f9. The overlays can now be drawn when PBVH drawing is not enabled, but the PBVH should still exist in the SculptSession in order to draw them. Before, it was avoiding the crash by checking use_pbvh as BKE_sculptsession_use_pbvh_draw also checks if the PBVH exists.

2020-10-01Volumes: support lower resolution in viewportJacques Lucke
The adds a new option to simplify volumes in the viewport. The setting can be found in the Simplify panel in the render properties. Volume objects use OpenVDB grids, which are sparse. For rendering, we have to convert sparse grids to dense grids (for now). Those require significantly more memory. Therefore, it's often a good idea to reduce the resolution of volumes in the viewport. Reviewers: brecht Differential Revision: https://developer.blender.org/D9040 Ref T73201.

2020-09-22Fix T81026: Image Editor: Alpha (like Bloom) not showing properlyJeroen Bakker
With the new image editor drawing there were was some mutual exclusive functionality. When rendering the alpha was shown correctly or the pure emissive colors were shown correctly, but never both. The cause of this is that the image_gpu did not used the correct alpha mode when generating gpu textures for non-images (render results, compositors viewer) The implementation always checked the alpha_mode. Alpha mode is an attribute for images, but aren't set for non images. This patch adds a more detailed check to ensure that the gpu texture is premultiplied. The issue has been tested using several bug report files and production files. Reviewed By: Brecht van Lommel Differential Revision: https://developer.blender.org/D8978
