------- Additional comments from [email protected] Tue Sep 29 13:12:19 +0000 2009 ------- AW: Took a closer look at the 3D object. It's a rotation object constructed of a PolyLine (break it open in draw) with 194 points, divided into multiple shapes, none of them closed and all with a LineWidth of 0,5 cm and 85% transparency. This indeed WILL expand to a VERY expensive 3D geometry; each fat line is extended to 2D geometry and then rotated; all that painted in transparency mode in 3D. I can not reproduce how that shape may have been constructed; as said, the partial polygons are not closed, but look as if they should be. The lines have an unknown type of LineEnds, too (circles?), which seem to be defined as beziers and also have a radius of 0.5. All that creates a massive 3D geometry and there is no way to change that. The only way to get such a monster of 3D geometry painted faster is a HW-accelerated 3D renderer. Even that renderer would need the geometry construction, which will be a good part of the time used. Also helpful will be to parallelize the 3D software renderer, but the best thing would be not to define such geometries. Extremely complex geometries like this one WILL get slow whatever system running on or whatever rendering hardware will be used. AW: Also checked with DEV300 m29 (last version without primitives): The 3.0 is also pretty slow with this, but faster. I guess the difference is that 3D is now AAed, too. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
