2020-10-09Revert "CleanUp: Introduce `eMeshBatchDirtyMode` enum"Jeroen Bakker
This reverts commit 0796807720882731cdb70be144aa182e9b0b9ee5.
2020-10-07CleanUp: Introduce `eMeshBatchDirtyMode` enumJeroen Bakker
It used to be an `int mode`.
2020-09-16Cleanup: use uint8_t for various flags in curvesJacques Lucke
Previously, it was kind of a mess. In different places it was using `char`, `short` and `int`. The changed properties are flags that are operated upon using bit operations. Therefore, the integer type should be unsigned. Since we only use 2 bits of these flags, `uint8_t` is large enough. Especially note the change I had to make in `RNA_define.h` to make this work.

2020-06-19EEEVEE: Object Motion Blur: Initial ImplementationClément Foucault
This adds object motion blur vectors for EEVEE as well as better noise reduction for it. For TAA reprojection we just compute the motion vector on the fly based on camera motion and depth buffer. This makes possible to store another motion vector only for the blurring which is not useful for TAA history fetching. Motion Data is saved per object & per geometry if using deformation blur. We support deformation motion blur by saving previous VBO and modifying the actual GPUBatch for the geometry to include theses VBOs. We store Previous and Next frame motion in the same motion vector buffer (RG for prev and BA for next). This makes non linear motion blur (like rotating objects) less prone to outward/inward blur. We also improve the motion blur post process to expand outside the objects border. We use a tile base approach and the max size of the blur is set via a new render setting. We use a background reconstruction method that needs another setting (Background Separation). Sampling is done using a fixed 8 dithered samples per direction. The final render samples will clear the noise like other stochastic effects. One caveat is that hair particles are not yet supported. Support will come in another patch.

2020-06-15Fix curve handle color ID displayCampbell Barton
Regression in 49f59092e7c8c caused all handles to display using the 'aligned' theme color. Arrange flags to fix this, add assert to avoid this happening again. Also rename flag so it's use is clearer.
2020-05-26Curves: Implement Handles for selected points onlyAntonio Vazquez
When editing a complex curve is very annoying to have all handles at a time. Also, this is a requirement for the current GSoC Edit Grease Pencil using curves. I have seen that this improvement can be used in any other area of blender, so I have decided to publish the option in the overlay panel..

2020-02-05Fix T70121 EEVEE/GPencil: Curves cause crash when using background renderingClément Foucault
This was caused by a faulty initialization of cache->surf_per_mat which should have been empty.

2020-01-30DRW: Add support for tangent on objects using display lists.Clément Foucault
Only Metaballs are left unsupported. However, the implementation does not match 100% with cycles which converts all objects to meshes. Fixes T63424 EEVEE: Normal map node doesn't works with curve objects
2020-01-28Fix T72593 Blender crashes when modifier change the material countClément Foucault
Instead of changing the modifiers behavior, we make sure to always use the data->totcol instead of the ob->totcol. Also we centralize getting this number to avoid future issues. Fix T72593 Blender crashes when separating mesh Fix T72017 Crash on set visibility change

2019-07-02Fix T65468 Nurbs: Broken display when hiding control pointsClément Foucault
2019-05-30GPU: Remove GPU_INDEX_U8Clément Foucault
This type of indices is not natively supported on modern GPU and gives warning on some implementation. The memory savings it provides is also quite minimal and unlikely to be visible on nowadays hardware. This remove some uneeded struct members and makes primitive restart always enabled by default. This can be broken by addons if they are not careful enough but many other states have this problem. Also leverage GL_PRIMITIVE_RESTART_FIXED_INDEX if ARB_ES3_compatibility is supported. This removes all API calls to change restart index depending on indices length.

2019-03-28DrawManager: Add Edge Detection To DisplayListsJeroen Bakker
Objects that internally uses DispList do not cast shadow in the workbench. Their outline is also not visible in object mode. The reason for this is that edge detection was not implemented for Display Lists. This patch will implement the edge detection.

2019-02-05Edit Mesh: Refactor Edit cage drawing to use old style drawingClément Foucault
This is work in progress. Look is not final. This align data VBO data structure used for edti cage drawing to the one use for normal drawing. We no longer use barycentric coords to draw the lines an just rasterize line primitives for edge drawing. This is a bit slower than using the previous fast method but faster than the "correct" (edge artifact free) method. This also make the code way simpler. This also makes it possible to reuse possible and normal vbos used for shading if the edit cage matches the This also touches the UV batch code to share as much render data as possible. The code also prepare for edit cage "modified" drawing cage (with modifier applied) but is not enabled since selection and operators does not work with modified cage yet.
2019-02-03Cleanup: trailing commasCampbell Barton
Needed for clan-format not to wrap onto one line.
2019-02-01Cleanup: remove redundant, invalid info from headersCampbell Barton
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.

2018-12-14Displist: Reuse tesselated pos and nor for wireframesClément Foucault
This lower the memory usage and also fix a bug with metaballs normals/tris winding being reversed.
2018-12-14Curve Batch Cache: Add back support for shaded geometryClément Foucault
This changes a bit the batches data structure. Instead of using one vbo per material we use one for all material and use index buffers for selecting the correct triangles. This is less optimized than before but has potential to become more optimized by merging the wireframe data vbo into the shading one. Also the index buffers are not strictly necessary and could be just ranges inside the buffer. But this needs more adding things inside GPUIndexBuf.
2018-12-14Curve Batch Cache: Rework Implementation to use new batch requestClément Foucault
Shaded triangles are not yet implemented (request from gpumaterials). This also changes the mechanism to draw curve normals to make it not dependant on normal size display. This way different viewport can reuse the same batch.

2018-12-07DRW: Rework wireframe overlay implementationClément Foucault
The shader is way simpler and run way faster on lower end hardware (2x faster on intel HD5000) but did not notice any improvement on AMD Vega. This also adds a few changes to the way the wireframes are drawn: - the slider is more linearly progressive. - optimize display shows all wires and progressively decrease "inner" wires intensity. This is subject to change in the future. - text/surface/metaballs support is pretty rough. More work needs to be done. This remove the optimization introduced in f1975a46390a5bf85bb7012375f9bc1e761fc516. This also removes the GPU side "sharpness" calculation which means that animated meshes with wireframe display will update slower. The CPU sharpness calculation has still room for optimization. Also it is not excluded that GPU calculation can be added back as a separate preprocessing pass (saving the computation result [compute or feedback]). The goal here was to have more speed for static objects and remove the dependency of having buffer textures with triangle count. This is preparation work for multithreading the whole DRW manager.
