I have a Performer 2.0 application that visualises a database.
The applications runs on a Onyx RE2 and a MaxImpact.
On the MaxImpact there is an error visible when there are 2 textured
polygons that have a texture with transparency and they
both share a region of the screen. The error is when the calculated transparency
value of the pixel is between 0.0 and 1.0. Then the Z-buffer value
is changed to the value of the polygon that is first drawn.
The effect you get is an edge of the background color drawn
over an opague part of the polygon that is further away.
I have the same effect if I load the database in perfly.ogl.
On the RE2 it looks the way it should be.
The graphics info of the MaxImpact is:
Graphics board 0 is "IMPACT" graphics.
Managed (":0.0") 1280x1024
2 GEs, 2 REs, 4 TRAMs,
HQ rev A, GE11 rev B, RE4 rev A, PP1 rev A, TE1 rev A
MGRAS revision 3, RA revision 5, RB revision 4
VC3 rev A, Cmap rev D, MC rev C
Can anybody tell me if this because of the graphics hardware in the MaxImpact
or due to Performer 2.0?
