Hi Away3D Community, We're developing an educational simulation based on Away3D for usage with PhET Interactive Simulations <http://phet.colorado.edu/>, and we're running into a rendering problem. The problem is that when a line segment or outline intersects with a surface, there are significant errors in the rendering. We posted an example to demonstrate the problem: http://www.colorado.edu/physics/phet/dev/density-flex/0.01.09/density-flex_en.html
To demonstrate the problem, visit the link above, then go to the second tab titled "Advanced". We are drawing a red line segment at the tip of each force arrow. Notice that when a red Segment intersects another object (the water or ground), there are many rendering artifacts. You can grab the block and move it around so that you can control reproduction of the error. This is built using an earlier version of Away3D, but we also tested against 2.5.0 and 3.5.0 and the same problem exists there. We are using renderer = Renderer.INTERSECTING_OBJECTS, and the problem occurs for addSegment(new Segment(...)) as well as for adding an outline to the arrow geometries. We reproduced the error to varying degrees with other renderers, but INTERSECTION_OBJECTS seems to work best for the rest of the graphics. Thanks, any ideas would be very helpful, Sam Reid/Jon Olson PhET Interactive Simulations
