Class TransformationMatrix


  • public final class TransformationMatrix
    extends java.lang.Object
    Represents a more precise way to represent Camera properties than using just heading, pitch and roll. The quaternion is used to describe the camera angles and the translation vector is used to describe the camera position.

      • createIdentityMatrix

        public static TransformationMatrix createIdentityMatrix()
        Creates a TransformationMatrix object with an identity transform. Subtracting another TransformationMatrix from an identity matrix is useful for getting the inverse of that TransformationMatrix, i.e., identity matrix - other matrix = inverse(other matrix)
        Returns:
        an identity TransformationMatrix
