Hi, I'm new in writing cg shaders. I'm wondering what parameters are available inside a cg shader. I want to write a wireframe shader, so I need to get access to the vertices of the triangle being rendered. Is this possible? thanks for your answers

For the parameters, check the Cg Toolkit PDF (user manual) file that's installed along with Cg, since it'll tell you more than you need to know. As for the whole wireframe thing, if you're using D3D, I can't help, but if you're using OpenGL, you can use this:


glPolygonMode(GL_FRONT_AND_BACK,GL_LINE);
//draw wireframe things here
glPolygonMode(GL_FRONT_AND_BACK,GL_FILL);
