// Compute color (vertex shader).

    // Compute color.
    // These shaders really use a single color (no ambient/diffuse/specular components).
    // Reference:
  //var_colorAmbientEmissive = gl_FrontLightModelProduct.sceneColor + ambient * gl_FrontMaterial.ambient;
  //gl_FrontColor = var_colorAmbientEmissive + diffuse * gl_FrontMaterial.diffuse;

    var_colorAmbientEmissive = gl_FrontLightModelProduct.sceneColor + gl_FrontMaterial.ambient;
    gl_FrontColor = var_colorAmbientEmissive + gl_FrontMaterial.diffuse;
