Re: More wireframe renderer

[Stefan H. <st...@to...>]

The behaviour between renderers and (fill) styles is not consistent.

Quesa Interactive renderer supports TQ3FillStyle:: kQ3FillStyleEdges 
in combination with TQ3BackfacingStyle:: kQ3BackfacingStyleRemove. 
That is what you have probably seen in Geom Test.

Quesa Wireframe renderer does not support the above combination. 
Actually Quesa Wireframe should ignore TQ3FillStyle (at least 
kQ3FillStyleFilled). Quesa Wireframe + kQ3BackfacingStyleRemove 
(ignoring kQ3FillStyleFilled ) should have (more or less) the same 
(redundant) effect as Quesa Interactive + kQ3FillStyleEdges + 
kQ3BackfacingStyleRemove.

Under QD3D there was a slight difference. QD3D Interactive + 
kQ3FillStyleEdges + kQ3BackfacingStyleRemove showed triangle edges 
(exception: high level geometries like cube). QD3D Wireframe showed 
surface edges.

By the way, Quesa OpenGL renderer does not support kQ3FillStyleEdges 
in combination with kQ3BackfacingStyleRemove.
