        New texture environment function COMBINE4_NV allows programmable
 
10
        texture combiner operations, including

12
            ADD                     Arg0 * Arg1 + Arg2 * Arg3
 
13
            ADD_SIGNED_EXT          Arg0 * Arg1 + Arg2 * Arg3 - 0.5
 
14
        
 
15
        where Arg0, Arg1, Arg2 and Arg3 are derived from
 
16
        
 
17
            ZERO                    the value 0
 
18
            PRIMARY_COLOR_EXT       primary color of incoming fragment
 
19
            TEXTURE                 texture color of corresponding texture unit
 
20
            CONSTANT_EXT            texture environment constant color
 
21
            PREVIOUS_EXT            result of previous texture environment; on
 
22
                                    texture unit 0, this maps to PRIMARY_COLOR_EXT
 
23
            TEXTURE<n>_ARB          texture color of the <n>th texture unit
 
24
        
 
25
        In addition, the result may be scaled by 1.0, 2.0 or 4.0.
