'Can I use an integer texture as if it was normalized?
I have a texture that has the format GL_RED_INTEGER. This texture has been generated with a compute shader.
I have another shader that I use for debugging that just displays the texture. Since it's an integer texture, I have to declare it in the shader as usampler2D. And also I have to divide it by 255.0, in order to normalize it.
However, I would like to reuse this debugging shader for other non-integer textures.
I though there might be some way to use the integer texture as if it was normalized. Is there?
Solution 1:[1]
I just remembered texture views exist in OpenGL. It's important to make sure that the texture has been allocated with glTexStorage2D as opposed to glTexImage2D; otherwise it's not possible.
