I would also think that the relevant docs for that is the OpenGL standard documents or the extension specification documents. both from kronos.
> Do we have a minimum OpenGL version requirement? 1.3 vs 1.4 vs 2.0? No, we don't. And the current code should be able to render well on pretty old versions. Even if some shaders dont' work, the old fixed function stuff should still give fine pictures. At least if the extension requirements are correct in the effect files. So, not sure if there is something we can do to make the 3d textures work on apple. Could you also double check if the osg extension check works correctly on your install? May be by just stepping into that with the debuger? That could also explain the error message you postet. That one looks to me like the texture is not found by the linker. May be because of some part of the code not setting the texture state for this texture?! Greetings Mathias ------------------------------------------------------------------------------ Write once.
