I am investigating on the performance of the different screen clear modes
provided by Performer 2.1 on an Infinite Reality (with iR-specific patch 1355
installed). Two questions :
- is z-buffer "tag" clear mode still supported or even relevant on this
platform ? Using perfly, the PFES_TAG option does not appear on the GUI.
- when using pfESky mode PFES_SKY, what is actually being done on the
lower part of the horizon? According to the man pages, nothing. But obviously,
some resetting of the z-buffer is done, since any moving objet within this zone
is acually drawn properly...
In any case, what is _really_ the best performance solution when it comes to
clearing the screen on an iR ?
Thanks for any kind help,
Gilles
