    texturing, vertex and pixel shaders

    my current opengl 1.1 engine is ready for me to implement texturing. using my trusty quadro fx 500 I'm planning on adding 3d textures as well as, pixel and vertex shaders. it seems natural to implement pixel and vertex shaders alongside 3d texturing for a overall simpler scenegraph.

    ********************************************
    Is it possible for me to implement pixel and vertex shaders on nvidia chipsets without migrating to cg, or dx?
    ******************************************
    is it possible to write assembly pixel and vertex programs to incorperate into my current opengl engine? (I have written plenty of assembly code by the way)
    *********************************************
    sup, I'm a CS undergrad at UAA in anchorage alaska. my main interests is in computer graphics.

    Yes, you can use the GL_ARB_VERTEX_PROGRAM extension for certex shader, and GL_ARB_FRAGMENT_PROGRAM extension for pixel shader !

    Re: texturing, vertex and pixel shaders

    That's right, but for vertex and pixel shaders to work, you will need at least a GeForceFX, Quadro FX or an ATi Radeon9500. If you want your application to run on lower hardware you will have to disable vertex and pixel shaders.
