Thanks to much help from David Fanning and Beau Leeger at RSI I am making progress on an object graphics program. I can now create a polygonal mesh with SHADE_VOLUME and then display it with object graphics. I need to triangulate (tesselate) the polygonal mesh, which is what IDLgrTesselator is supposed to do. When I try to create a tesselator object, however, I get: IDL> tri = OBJ_NEW('IDLgrTesselator') % Attempt to call undefined procedure/function: 'IDLGRTESSELATOR__DEFINE'. % Structure type not defined: IDLGRTESSELATOR. and when I do HELP, /OBJECT there are no tesselator-related objects defined, although there are definitions for a lot of other objects that I have not used. This is IDL Version 5.0.2. Any ideas? E-mail replies appreciated. Change the AT to @ in my e-mail address. Thanks, Ken Bowman bowmanATcsrp.tamu.edu
