FixedWidthViewSizer

Page Summary

• FixedWidthViewSizer controls the size of a ViewRenderable in a Scene by setting a fixed width in meters, automatically adjusting the height to maintain aspect ratio.

• It provides methods to calculate the size of the view in the Scene and to retrieve the defined width.

• The constructor takes a float value representing the desired width in meters.

• getSize() method calculates and returns a Vector3 representing the view's size in the Scene.

• getWidth() method returns the fixed width value set during the FixedWidthViewSizer's construction.

public class FixedWidthViewSizer

Controls the size of a ViewRenderable in a Scene by defining how wide it should be in meters. The height will change to match the aspect ratio of the view.
