defi (Vertex Shader)
Defines an integer constant value, which should be loaded anytime a shader is set to a device.
Syntax
| defi dst, integerValue0, integerValue1, integerValue2, integerValue3 |
|---|
- dst is the destination register.
- integerValue# is a constant integer value.

The defi (Vertex Shader) instruction defines an integer shader constant whose value is loaded anytime a shader is set to a device. These are called immediate constants. Immediate constants take precedence over constants set by the application programming interface (API) method SetVertexShaderConstantI.
There are two ways to set an integer constant in a shader.
- Use defi (Vertex Shader) to define the integer constant vector directly inside a shader.
- Use the API methods to set a constant.
