More Tips To Generate Better PS_1_x Code Through Good HLSL Use • Complement (1 – x) 1 – value generates 1 – rX modifier on the source register, where rX is the source register. • Saturate ( _sat ) – Use either saturate() or clamp() intrinsics – _sat can be combined with other modifiers • Negate ( - X ) – Simplest to use: generates • Bias (_bias) value * 0.5f return –Color; mov r0, -c0 generates _bias modifier on the source register – Note that _bias cannot be used in ps_1_1/2/3 unless the source is in [0,1] range Game Developer Conference, San Jose, CA, March 7 th 2003
Summary • Use HLSL for your shader development – All the usual advantages of High Level Languages • Faster, easier development • Code re-use • Optimization – Current HLSL compiler is very good and getting better every day – Industry standard which will run on any DirectX® shader chip • Use RenderMonkey for your shader prototyping and development – Powerful tool with intuitive interface – Prototype your shaders and then fully explore them like never before until you find the look you like Game Developer Conference, San Jose, CA, March 7 th 2003
