Web24 de jan. de 2024 · (This is somewhat of a continuation of my previous post) I’ve been trying for more than a week to add indirect rendering with a compute shader. I can’t find any useful resources. The closest I’ve found was this blog post. However, it’s missing exactly what I’m struggling with. Currently I have 3 shaders, compute, vertex, and fragment. I … WebIndirect rendering is the process of issuing drawing commands to the graphics API, where most of the parameters to those commands come from GPU buffers. It is a part of many modern GPU usage paradigms, and it exists in all contemporary rendering APIs in some form. For example, we can do indirect rendering with OpenGL using the … kirchner law firm

WebCurrently I'm supporting Simple, Indexed, Indirect and Indexed Indirect draw commands. The appropriate draw call is selected using a simple switch, using the glDraw--Instanced or glMultiDraw--commands. What I'm planning to do instead though, is use only the multi draw commands, and implement instancing under the hood using parameter duplication.
