The Transform method of the Matrix struct is used to apply a transformation to a given Vector3 using the matrix. This method multiplies the vector by the matrix, effectively transforming the vector according to the matrix's transformation rules, which may include translation, rotation, scaling, or any combination of these.
To use the Transform method, you need an instance of a Matrix and a Vector3 that you wish to transform. Call the method on the matrix instance, passing the vector as a parameter. The method returns a new Vector3 that represents the transformed vector.
// Example of using the Transform method Matrix transformationMatrix = Matrix.CreateRotationX(45.0f); Vector3 originalVector = new Vector3(1, 0, 0); // Transform the vector using the matrix Vector3 transformedVector = transformationMatrix.Transform(originalVector); // transformedVector now contains the result of the transformation
