Syntax

dcl v#.components

where:

• dcl is a register declarator. See dcl.
• v is a vertex register and # is the register number.
• components are the [xyzw] or [rgba].

Remarks

• There are two pixel shader vertex color registers: v0 and v1. They are read-only registers.
• They contain four-component RGBA values iterated from input vertices.
• They have lower precision than most registers, guaranteed to have 8 bits of unsigned data in the range 0, +1.
• There is a maximum of one in a single instruction.
