dst (Vertex Shader)
Calculates a distance vector.
Syntax
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 |

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).
