size
The physical [width, height] size of the canvas in world coordinates. viz.AUTO_COMPUTE can be used with either the width or height to automatically compute the size to maintain aspect ratio with the resolution.
This command will set the canvas to render within the world. You can think of it as a virtual computer monitor. The monitor has the specified pixel
resolution and physical
size dimensions.
This mode can be used to fix the GUI elements within the world, instead of attached to the view, as with
<node3d:canvas>.setRenderWorldOverlay.
The mouse style will most likely need to be changed to
viz.CANVAS_MOUSE_VIRTUAL or
viz.CANVAS_MOUSE_VISIBLE, depending on the input device used. See
<node3d:canvas>.setMouseStyle for more information.
The default render mode of the canvas is world overlay, with the following settings:
canvas.setRenderWorldOverlay([1280,720], fov=50.0, distance=3.0)
