abs (macro)

ps 2.0

This macro computes the absolute value of the input register on an element by element basis.

---

One arithmetic instruction slot.

2.0				x	x	x	x	x

Computes the absolute value of each element of Source0 and places the result in Dest0.

abs r4, r4

this macro is equivalent to the following code.

cmp Dest0, Source0, Source0, -Source0

add	ps 1.0 – 2.0

Adds two source colors and places the sum into a third register.

---

One arithmetic instruction slot.

1.4 Phase 2

This instruction takes two source registers, applies the 2x2 bump-map matrix to Source1, adds in Source0 and places the result in the destination register. This instruction only operates on the .rg components. The matrix values are set prior to the pixel shader through a SetTextureStage call setting the four D3DTSS_BUMPENVMATnn matrix elements. The destination register number determines the texture stage number. There are no restrictions on modifiers on the source registers. There are restrictions on using the bem instruction;

• Only one bem instruction can appear in a shader.
• The bem instruction must be in phase 1.
• The source registers can be a temporary or constant registers.
• The destination must be a temporary register.
• The destination mask must be .rg (or .xy)
• The instruction cannot be co-issued.

Note: This instruction works only in PS 1.4.

bem r3.rg, r0, c2 // bump texture 3 * c2, add in r0

bem r4.xy c2, r0 // bump texture 4 * r0, add in c2

cmp	ps 1.2 - 2.0

Compare: Performs a conditional assignment based upon a comparison of the values in the source registers.
