The following shader performs a one-matrix transform with constant color. The input vertex register v0 is the position, which is assumed to be homogeneous. The transform matrix is in the constant registers (c[0] through c[3]). Diffuse color is loaded into c[4].
dp4 r0.x, v0, c[0] dp4 r0.y, v0, c[1] dp4 r0.z, v0, c[2] dp4 r0.w, v0, c[3] mov oD0, c[4] ; The constant color. mov oPos, r0 ; Emit the output.
This shader executes in six clock cycles.
