I have been trying to figure out how to mask Geos with other Geos but I have hit a big roadblock.
Following the example in gem/openGL I have made 2 objects but it seems that Gem will only
recognize 1 or the other. I have attached an example. If anyone with openGL understanding could
give me a hand I would really appreciate that.
Thanks, Alain

hi nosehair,
In GLBuffer it seems you are sending both geos to the same buffer. GL_STENCIL_TEST. by changing them so they correspond to the GLend statements you can get the cirlce masking out the square circle from the second gemhead
This code seams very foreign to me, I seem to be missing a few of the abstractions, where is there documentation on GEMgl ?
