blender-core-gpu

Use when drawing custom overlays, viewport visualizations, or offscreen renders in Blender Python. Prevents the critical mistake of using the deprecated bgl module (removed in Blender 5.0) instead of the gpu module. Covers gpu.shader, gpu.batch, gpu.state, SpaceView3D draw handlers, built-in shaders, and BGL-to-gpu migration. Keywords: gpu module, bgl, draw handler, viewport overlay, offscreen rendering, SpaceView3D, shader, UNIFORM_COLOR, Blender Python drawing, draw on viewport, custom overlay, draw lines in 3D view.
