- 12-bit per channel color RGBA (96-bit double-buffered)
-
- How will this work with current color and frame buffer routines?
-
- I know getgdesc will return the number of bits/channel so I assume
- we, the graphics programmer, will have to specify values between
- 0-4095 for the c*s and c*i routines. c*f values would be properly
- mapped by the GL library. What about cpack? Will it modify the
- 8 most significant bits? What about lrectread? Will it handle
- 48 bit/pixel data? (current man page says max is 32 bits/pixel)
-
- New texture mapping modes, including bicubic interpolation and
- 3D textures
-
- How is this done? By stacking up a bunch of 2-D textures or can
- we provide a pointer to a function that, given u, v and w, returns
- a color?
