(

int

fromFrameBufferId

)

both buffers must have the same dimensions and configurations (textures + depth)

Parameters:

This will read the content of the depth buffer We can only read the buffer if it is enabled, if it isnt set active to true.

Parameters:

activeBuffer

we can only read the buffer

Returns:

float array, one float per pixel only
