Dynamic Multisample Antialiasing
Multisampling (full-scene dynamic multisample antialiasing) removes the jagged
edges on 3D data. An image is sampled at a higher resolution than the screen,
typically two to eight samples per pixel. This method yields improved images, but at
the price of possibly increased render time.
The Sun XVR-600 graphics accelerator has 64 Mbytes of memory for the frame buffer
so that the image can be multisampled at up to eight samples per pixel in a single
pass, depending on the resolution. The higher number of samples per pixel, the
better the image quality but the longer the rendering time (and the more memory is
consumed). Depending on the video format (
TABLE 1-1 on page 6), the number of
samples per pixel, or sample density, can be increased to improve image quality.
To invoke multisampling, use the fbconfig command’s -multisample and
-samples options. You can enable multisample mode for all Sun OpenGL for
Solaris applications.
fbconfig controls frame buffer memory consumption (at the time the X window
system starts).
