Re: [JAVA3D] multitexturing and OpenGL Extensions

[Philip Taylor]

most current hardware supports 2-3 texture stages.   geForce3 supports 4. Kyro I and Kyro II support 8.   expecting to use 10-30 textures per primitive is guaranteeing many passes, 10-15 for most hardware, and poor performance. -----Original Message----- From: Michael Nischt [mailto:[EMAIL PROTECTED]] Sent: Wednesday, June 27, 2001 1:54 PM To: [EMAIL PROTECTED] Subject: [JAVA3D] multitexturing and OpenGL Extensions hi all, i have got a few question, hoping that s.o. can answer them:   1. AFAIK is it possible to do multitetexturing in Java3D - and there is a bug, that it is only done BY_REFERENCE (right David ?) - but  that don'T mind me. so my question is in how far performace suffer from multitexturing and how many textures can be aplied to one geometry? is it far slower to use 10-30 textures on one geometry than splittng the geometry apart in 10-30 unique geometries with own textures ?   2. IIRC OpenGL needs an extensions for multitexturing (GL_ARB_multitexture) so Java3D uses extensions... it would be very interesting which extensions are used ?   gruss Michael Nischt ------------------------------ e-mail:          [EMAIL PROTECTED] homepage:    http://zero.atariflys.de ---------------------------------------------------------------
