Render millions of AABBs every frame with an instancing renderer.

Plugins

Two render plugins are provided.

The [InstancingRenderPlugin] does what you might call "canonical" mesh instancing. It does a single instanced draw call per [Cuboids] entity by "pushing" vertices through the shader pipeline. Current limitation: You must spawn your entities with a [CuboidInstancesBundle] for this plugin to work.

The [VertexPullingRenderPlugin] uses the "vertex pulling" technique to render all entities with a [Cuboids] component. In vertex pulling, rather than pushing vertex attributes through the shader pipeline, you only push an index buffer, and the shader "pulls" your instance data from a storage buffer by decoding the vertex_index input.

The [VertexPullingRenderPlugin] can be significantly faster, but it also depends on your platform. Benchmark for yourself.
