These correspond to levels 2 through 6 respectively. If base is 3 and max is 5, then only mipmap levels 8x4x2, 4x2x1 and 2x1x1 are loaded. However, if max is 7 then an error is returned and nothing is loaded since max is larger than the highest mipmap level which is, in this case, 6. See the glTexImage1D subroutine for a description of the acceptable values for format parameter. See the glDrawPixels subroutine for a description of the acceptable values for type parameter.
Parameters target Specifies the target texture.
These should be a power of 2. These should be a power of 2. depth Specifies the depth, in pixels, of the texture image.
