WorldViz User Forum - Is it possible to have make my shapes have black borders?

Here is a sample script showing how to draw a black line over the wireframe of a model:

Code:

import viz

import vizact

viz.go()



viz.clearcolor(viz.GRAY)



frag_black = """

        void main()

        {

        gl_FragColor = vec4(0,0,0,1);

        }

        """

shader_black = viz.addShader(frag=frag_black)



def addWireOutline(node):

        node.wire = model.clone(parent=node)

        node.wire.polyMode(viz.POLY_WIRE,op=viz.OP_OVERRIDE|viz.OP_ROOT)

        node.wire.zoffset(op=viz.OP_OVERRIDE|viz.OP_ROOT)

        node.wire.apply(shader_black,op=viz.OP_OVERRIDE|viz.OP_ROOT)



model = viz.addChild('ball.wrl',pos=(0,1.8,2))



addWireOutline(model)



model.addAction(vizact.spin(0,1,0,90))



vizact.onkeydown(' ',model.wire.visible,viz.TOGGLE)

Let me know if I misunderstood what you were asking for, or if anything is unclear.
