jump to expanded postOpenGL question: is there some way to share the storage between a renderbuffer and a texture, or directly convert a renderbuffer to a texture? note: I know I can construct a framebuffer and use it to copy a renderbuffer to a texture, Iโm just wondering if I can skip that step
if I have to use functions from the platform API (i.e. not just gl* stuff) then the answer may as well be โnoโ though
hey wait what if I made a pixelbuffer and used glReadPixels and then glTexImage2D

hikari no, thatโs just asking for terrible performance, just use framebuffer blitting at that pointโฆ
@hikari dare I ask, why do you want to avoid using a framebuffer?
@aeva itโs not that I want to avoid using a framebuffer, Iโm just forced by, uh, the specific legacy code I am dealing with, to render everything to a renderbuffer, and it just frustrates me that I have to copy it to another thing (a texture) before I can do anything useful with it
@hikari oh no D:
