dst - vs

  • Článek

Calculates a distance vector.

Syntax

dst dest, src0, src1

 

where

  • dest is the destination register.
  • src0 is a source register.
  • src1 is a source register.

Remarks

Vertex shader versions 1_1 2_0 2_x 2_sw 3_0 3_sw
dst x x x x x x

 

The following code fragment shows the operations performed:

dest.x = 1;
dest.y = src0.y * src1.y;
dest.z = src0.z;
dest.w = src1.w;

The first source operand (src0) is assumed to be the vector (ignored, d*d, d*d, ignored) and the second source operand (src1) is assumed to be the vector (ignored, 1/d, ignored, 1/d). The destination (dest) is the result vector (1, d, d*d, 1/d).
