simple question drawing to screen

[Kaminski]

I can't figure out how to draw to screen separately for the LEFT and RIGHT eyes. I just want to make 2-dimensional polygons but have the left and right eyes see completely different views. Heres what I've been trying:


import viz
viz.go(viz.HMD | viz.SEREO)
viz.startlayer(viz.LINE_LOOP)
viz.vertexcolor(viz.BLUE)
viz.linewidth(1)
viz.vertex(0.2,0.2)
viz.vertex(0.2,0.5)
viz.vertex(0.5,0.5)
viz.vertex(0.5,0.2)
line = viz.endlayer(viz.SCREEN,viz.LEFT_EYE)


I know that last line is flat out wrong, but I can't find how to say it.

You can use the viz.RENDER_RIGHT and viz.RENDER_LEFT flags to prevent a node from rendering to a specific eye in stereo. In your example, if you wanted the line to only show up on the left eye, then you would use the following code:import viz
viz.go(viz.HMD | viz.STEREO)

viz.startlayer(viz.LINE_LOOP)
viz.vertexcolor(viz.BLUE)
viz.linewidth(1)
viz.vertex(0.2,0.2)
viz.vertex(0.2,0.5)
viz.vertex(0.5,0.5)
viz.vertex(0.5,0.2)
line = viz.endlayer(viz.SCREEN)
line.disable(viz.RENDER_RIGHT)

Thats it, thanks.
