GraphicsDevice.SetPixelShaderConstant Method (Int32, Vector3)

  • Článek

Sets the specified pixel shader constant float register to a Vector3 value.

Namespace: Microsoft.Xna.Framework.Graphics
Assembly: Microsoft.Xna.Framework (in microsoft.xna.framework.dll)

Syntax

public void SetPixelShaderConstant (
         int startRegister,
         Vector3 constantData
)

Parameters

  • startRegister
    Zero-based index of the pixel shader constant float register at which to begin setting values.
  • constantData
    The constant data.

Remarks

Because the data in the Vector3 type is not large enough to fill the constant float register, the constant data will be padded to fill the register. This means that setting register 0 to a Vector3 containing (1,2,3) will fill the register with (1,2,3,0).

Exceptions

Exception type Condition
ArgumentOutOfRangeException constantData is outside the allowable range of values as defined by the invoked method.
InvalidOperationException The method call is invalid. For example, a method's parameter may have an invalid value.
