    Full VP & FP

    Hi,

    I'm looking for a VP and a FP that make the lighting calculation as there was no programs.
    Is somebody have this for me ?

    Thanks

    Eeasy school project???

    You can find a cg shader at developer.nvidia.com called smthn like implementing fixed function pipeline in cg, should be easy to port to GLSL if you're familiar with syntax, parameter passing.

    You can't do the full lighting with a single VP+FP
    You need a whole set of them for each light type and also for the the number of lights.

    My web site has VP examples in ARBvp + NVvp1 +NVvp2 that does some of this.

    float matrix[16], inverse_matrix[16];
    glhLoadIdentityf2(matrix);
    glhTranslatef2(matrix, 0.0, 0.0, 5.0);
    glhRotateAboutXf2(matrix, angleInRadians);
    glhScalef2(matrix, 1.0, 1.0, -1.0);
    glhQuickInvertMatrixf2(matrix, inverse_matrix);
    glUniformMatrix4fv(uniformLocation1, 1, FALSE, matrix);
    glUniformMatrix4fv(uniformLocation2, 1, FALSE, inverse_matrix);

    See my profile.

    It's in the new demoes section, it's called VeryBasic VP
    It's also a GLUT program (WGL used, but can be easily changed for GLX)
