getViewTransform method

@override Matrix4 getViewTransform(Size dimensions)

Returns the combined projection-and-view transform for a render target of the given dimensions.

Called once per Scene.render call. Implementations may read dimensions (typically to compute aspect ratio) and any subclass configuration to build the matrix.

Implementation

@override
Matrix4 getViewTransform(ui.Size dimensions) {
  return _matrix4Perspective(
        fovRadiansY,
        dimensions.width / dimensions.height,
        fovNear,
        fovFar,
      ) *
      _matrix4LookAt(position, target, up);
}
