Set the render limit mode

<node3d>.setRenderLimit(
mode
)

mode

Limit modes
viz.RENDER_LIMIT_NONE	There is no limit to how many times the node will be rendered. This is the default mode.
viz.RENDER_LIMIT_FRAME	The node will be rendered at most once per frame.
viz.RENDER_LIMIT_WINDOW	The node will be rendered at most once per window.
viz.RENDER_LIMIT_EXCLUDE_MAIN_PASS	The node will be excluded from the main render pass.
viz.RENDER_LIMIT_EXCLUDE_RENDER_NODE	The node will be excluded from render node passes.

Remarks

This command can be used to limit how many times a node is rendered per frame. It is mostly used with certain render to texture nodes to prevent unnecessary duplicate rendering per frame. The default mode is viz.RENDER_LIMIT_NONE.

Return Value

None

Example

import viz
viz.go()

viz.add('lab.osgb')

model = viz.add('beachball.osgb',pos=(0,1.8,2))

window1 = viz.addWindow(pos=(0,1),size=(0.25,0.25))
window2 = viz.addWindow(pos=(0.75,1),size=(0.25,0.25))

viz.MainWindow.stereo(viz.STEREO_HORZ)
window1.stereo(viz.STEREO_HORZ)
window2.stereo(viz.STEREO_HORZ)
