- Is there a way in Performer to manage pagination of texture like
in GL .
- For managing the pfLayer i read that Perf1.2 uses
DisplacePolygon, but if i well remember displace polygon modify the Z
value of a polygon by a factor calculated by the use of the polygon
orientation, and this factor is 0.0 if the polygon as its normal oriented
direct to the viewer.So for coplanar polygon in front of the viewer it
will no works fine
Is'it right ??? Is there a way to avoid this ???
- Is there a way to store informations on every nodes of the
hierarchy ??
- I heard that Performer sorts the polygons before the drawing to
optimise the graphics (Especially mode transitions).But what kind of
sorting Performer uses .. Is it only to group polygons with the same
textures to avoid Texbind ???
- My last question is not especially for Performer guys, in fact
it seems that the GL call "msmask()" is very slow . Is it right ???
Thanks in advance
