GLSL Geometry Shader Question? category: code go to page 1 of 1   I'm trying to understand and use geometry shaders for a mesh generation problem with non-rendering purposes. In a setup where the shader receives GL_TRIANGLES and emits GL_TRIANGLE_STRIP, I send all vertices three at a time with glBegin(GL_TRIANGLES). Shader correctly receives primitives three vertices at a time. Can the vertices inside gl_PositionIn be sometimes in different orders than glVertex commands I execute on the host side or are they always FIFO? added on the 2010-08-01 13:45:39 by Optanes   No. It's always in the call order. added on the 2010-08-01 14:56:25 by xernobyl   i have a bug to fix then. thank you. added on the 2010-08-01 19:26:09 by Optanes   go to page 1 of 1
