Web9 de abr. de 2024 · While multi-draw indirect does in fact allow each draw to have its own instance count and base instance, instancing makes accessing per-object information much more complicated. Each draw index originally only used one piece of per-object information, so every draw command could just directly use its own index. Web24 de abr. de 2024 · I am working on a rendering engine that uses draw indirect and instanced rendering to render scene geometry. Some objects are procedurally generated from instanced base shape such as a cube or a sphere, others are mesh objects that are instanced and used all over the scene.
