Related to my other question, I think the more central question would be, how you render a QImage with OpenGL? I think the code has to look something like this, but I'm not sure what else I need, ...

What is the difference between glBindImageTexture and glBindTexture? And also what is the difference between the following declarations in a shader: layout (binding = 0, rgba32f) uniform image2D i...

I'm trying to upload a texture with unsigned shorts in a shader but it's not working. I have tried the following: glActiveTexture(GL_TEXTURE1); glBindTexture(GL_TEXTURE_2D, vbt[1]); glTexImage2D(...

Are glTexImage2D and glTexSubImage2D the only ways to pass a buffer of pixels to a texture? At the moment I use in a setup function glTexImage2D passing null as the buffer, and then on the render ...

If for example I create an array of pixels, like so: int *getPixels() { int *pixels = new int[10]; pixels[0] = 1; pixels[1] = 0; pixels[1] = 1; // etc... } glTexImage2D(..., getPixels()); ...

What is the difference between the two functions? Any performance difference? Thanks..

What is the border value of glTexImage2D? It's either 0 or 1. Does it decide whether this texture will have a border or not? Where is the border values set?
