Hi Usman,
Can you try the following example:
R3Example new edgeExample2
There are many many edges displayed and it moves smoothly. On Windows the example goes well. On my machine (MacBookAir), I have an error that appears times to time. If this is the case for you, simply modify the method with:
-=-=-=-=-=-=-=-=-=-=-=-=
R3Morph>>visibleObjectInScreenX: screenX y: screenY
| id |
stateTracker ifNil: [ ^nil ].
^ view
-=-=-=-=-=-=-=-=-=-=-=-=
Here is a screenshot:

Cheers,

The edge is created but not at the correct position, it might be due to the fact that I need to set the position of the edge shape or mismatch between position in Roassal and OpenGL. Can you please have a look?
