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. Web30 de dez. de 2024 · This work is intended to provide a fast rendering of large point clouds in OpenGL using compute shaders. It is built over an interface based on ImGui for easing the opening and visualization of large point clouds with a high rate of frames per second (FPS). This work is implemented from the research of Markus Schütz.
