GraphicsDevice.SetVertexShaderConstant Method (Int32, Vector3 )

  • 项目

Sets the specified vertex shader constant float registers to an array of Vector3 values.

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

Syntax

public void SetVertexShaderConstant (
         int startRegister,
         Vector3[] constantData
)

Parameters

  • startRegister
    Zero-based index of the vertex 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 registers, the constant data will be padded to fill the registers. This means that setting register 0 to to an array of Vector3 values containing (1,2,3) and (4,5,6) will fill register 0 with (1,2,3,0) and register 1 with (4,5,6,0).

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.
