O.K. - part of a simple app is provided here (http://pastebin.com/m5d4f562). It's the FLTK CubeView demo and with lighting added. This file has most of the OpenGL code for this app. It runs fine as listed (with stenciling turned off). It displays a solid, shaded, cube, which I can translate, rotate, scale, etc. Seems to me that if I use line 102 instead of 103, and line 139 instead of 140, the program should work exactly the same way. I'm simply trying to make the window capable of doing stencil operations. I'm not actually trying to do any stencil operations (yet). But - I get a blank window. BTW, it doesn't help if I explicitly disable the stencil test somewhere in the draw routine. Am I missing something basic here, or is there something wrong with FLTK 1.0.11's implementation of the stencil buffer? Thank you. _______________________________________________ fltk-opengl mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk-opengl
