Projecting textures

This plug-in allows you to add a light or shadow texture that is projected onto surfaces, and moves in relation to an object.

Procedure

This example shows how to use vizprojector to add an object, its projected textures, and surfaces on which to project.

import viz
import projector
viz.go()

viz.MainView.setPosition([0,1,-1])

#Add objects for the shadow to be cast upon
ground = viz.add('tut_ground.wrl')

#Sphere to have the shadow cast upon
ball = viz.add('white_ball.wrl')
ball.setScale([10,10,10])
ball.setPosition([0,0,4])

#Create projector group object
eyeBalls = projector.add(viz.add('eyeshadow.jpg'))

#Point shadow down
eyeBalls.setEuler([0,90,0])

#State the geometry that can have the shadow cast upon them
eyeBalls.affect(ground)
eyeBalls.affect(ball)

#Use a orthographic projection matrix instead of the default perspective projection matrix
eyeBalls.ortho(0.25,0.15)

#Add child geometry that follows shadow around
eyeGeometry = eyeBalls.add('eyeballs.osg')
eyeGeometry.setEuler([0,90,0])
eyeBalls.setPosition([0,1,3])
eyeBalls.addAction( vizact.spin(0,0,1,90))

Function	Takes	Description
fov	vertical, ratio	sets the field of view for the projection
ortho	width, height	sets the width and height of the projected texture
border	r,g,b	sets the color of the periphery
image	texture
affect	node	sets a node for projection
unaffect	node	removes a node from projection
