Web27 de jul. de 2024 · Image Load/Store is not intended to replace framebuffers. It's a feature that allows (relatively) arbitrary reading and writing to memory. So you would use images when you need to arbitrarily read and write to memory. You would use framebuffers when you're rasterizing primitives for rendering purposes. WebYes, you can bind a FBO and then render to it and then read with with a call to glReadPixels. It doesn't matter if what you have attached to the FBO is a RenderBuffer or a texture, glReadPixels will still read it and it will return the results. five percent of two million https://plumsebastian.com
