2 Pt Perspective

2 Point Perspective refers to a view where vertical lines remain vertical. (See SketchUp Sage Article)

SketchUp provides a special mode for two-point perspective. When this is selected, the view is changed so that vertical lines remain vertical (no vanishing point), and when panning or zooming the view, the target is moved as required so that the perspective of the image does not change. (Normally when you pan an image, the camera target is moved to the new center of the image, which causes the perspective to change.)

The latest beta of IRender nXt supports this properly, so that the rendered view matches the SketchUp view - even in panned 2D perspectives.
