Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Update Overlay engine to leverage the new capabilities of the new draw manager.
Requires #102177 (Draw: Selection Next)
Complex:
Medium:
Easy:
Added subscriber: @Jeroen-Bakker
Draw: Overlay-Nextto Overlay-NextThe engine design is now complete. Help with the port is welcomed.
Porting requires a bit of work but everything is clearer than the old implementation:
DRWCallBuffer
are replaced byShapeInstanceBuf
with the data type declared inoverlay_shader_shared.hh
.GPUBatch
for each shape (not object geometry) should be ported fromdraw_cache.c
tooverlay_shape.hh
.GPUShader
creation used must be ported tooverlay_shader.cc
tooverlay_shader.hh
.Look
overlay_empty.hh
drawing for a simple example of shape drawing.Look
overlay_prepass.hh
drawing for a simple example of object drawing.I have sorted the list of task by degrees of complexity.
Try to stick to the level of code quality this rewrite is at. Use
float4x4
and the blender vector types instead of blender C vector/matrix API when possible.Note that the Basic engine is going to be merged to the overlay engine for selection purpose. This means the basic engine features (such as conservative raster for selection) need to be ported.
