I am confused about how to do a simple texture memory calculation.

If I have a 1024 * 1024 texture, that is rgba, and I load it in, how much texture memory does it use?

I would guess 1024*1024*4 = 4 Megabytes.

If it is simply an intensity map, does it take 1 or two megs? I have been told that performer stores the textures internally as 16 bit, so a 8 bit 1024*1024 intensity map really takes 2Meg.

Could somebody please clarify how do do the calculation for monochrome, rgb and rgba?

Thanks.
