Hello dear JGO!
I am having a bit of a issue with my Gui rendering system. Currently, i bind a texture for every “Gui” i render. However, i want to make it more efficient by using a texture atlas, by specifying different texture coordinates for every texture. However, my problem is that i have the same vbo (It just contains vertex position data for a quad) for all of the Guis, and i just scale that quad in the shaders. However, to get my texture coords to the shaders, i will have to create a separate vbo for every texture.
I thought of maybe using glBufferSubData to change the vbo’s texture coords, but that doesn’t seem vary efficient.
Do you have any ideas? Thanks vary much
