ps (Pixel Shader)

This instruction specifies the shader version number and works on all shader versions.

Syntax

ps_mainVer_subVer

Input Arguments

Input arguments contain a single main version number with a single sub version number. The allowable combinations are listed in the table below.

Remarks

Pixel shader versions	1_1	1_2	1_3	1_4	2_0	2_x	2_sw	3_0	3_sw
ps	x	x	x	x	x	x	x	x	x

This instruction must be the first non-comment instruction in a pixel shader.

Hardware accelerated versions of the software (versions without _sw in the version number), can process vertices with hardware accelearation or use software vertex processing. Software versions (versions with _sw in the version number) process vertices only with software.

Examples

This partial example declares a version 1_1 pixel shader.

ps_1_1

This partial example declares a version 1_4 pixel shader.

ps_1_4
