Shader Type Syntax

Syntax

ShaderType vs = compile vs_2_0 psmain();

ShaderType ShaderName [= asm { ShaderAssemblyInstructions }];

where:

ShaderType	Can be either vertexshader or pixelshader.
ShaderName	An ASCII string that uniquely identifies the name of a variable within a shader.
ShaderAssemblyInstructions	Optional. Any set of assembly instructions. For vertex shader and pixel shader assembly instructions, see Asm Shader Reference.

Remarks

Vertex Shader

A vertexshader object represents a vertex shader object. While no operation within a shader function directly accepts vertex shaders, a vertex shader can be set to the device from within a technique.

Literal vertexshader values can be expressed as an assembly block in one line,

vertexshader vs = asm { vs.2.0 mov oC0, c0 };

or across several lines,

vertexshader vs = 
  asm 
  { 
    vs_2_0 
    mov oC0, c0 
  };

or as a compile call.

vertexshader vs = compile vs_2_0 psmain();

Pixel Shader

A pixelshader object represents a pixel shader object. While no operation within a shader function directly accepts pixel shaders, a pixel shader can be set to the device from within a technique.

Literal pixelshader values can be expressed as an assembly block in one line,

pixelshader ps = asm { ps.2.0 mov oC0, c0 };

or across several lines,

pixelshader ps = 
  asm 
  { 
    ps_2_0 
    mov oC0, c0 
  };

or as a compile call.

pixelshader ps = compile ps_2_0 psmain();
