translated(offset) → simvx.core.math.transforms.Transform2D

Return a new transform with position shifted by offset.

rotated(angle: float) → simvx.core.math.transforms.Transform2D

Return a new transform with additional rotation (radians).

scaled(factor) → simvx.core.math.transforms.Transform2D

Return a new transform with scale multiplied by factor.

transform_point(point) → numpy.ndarray

Transform a 2D point through this transform.

inverse() → simvx.core.math.transforms.Transform2D

Return the inverse transform.
