Time to plug-in a graphics card? Almost any nvidia model would do.I have a pair of Nvidia 9800 GT cards in my box, and yet the plain X Lesstif HID still blows everything else away. The cards alone are only part of the pipeline.
Do you have an explanation for this?I thought that X is pure 2D and thus only primitive operations have to be computed for each span of a shape. On the other hand, a full GL-engine will do the 2D/3D transformations and span computations in hardware, so all the CPU has to supply is untransformed
vertices. What may slow down the GL version is transparency.One big factor may be the R-tree acceleration built into the X implementation. This will be difficult to emulate, if one wants to use display lists in GL. Otoh
a sensible GL implementation will do frustum culling - so why? _______________________________________________ geda-user mailing list geda-user@xxxxxxxxxxxxxx http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
