I had to close that post before I could mention where all that discussion was going. Briefly, I have been trying from the start to design BrickDraw3D's C++ classes to separate geometry and graphics from the application framework (in this case (...) (23 years ago, 11-Feb-02, to lugnet.cad.dev.mac)

I haven't commented substantially on LCD, so maybe I should. I am contemplating an algorithm that will find all of the possible stud-insertion points on a part. The obvious way to do this is to recognize the tube or enclosing box with their (...) (23 years ago, 11-Feb-02, to lugnet.cad.dev.lcd)

(...) I think it probably is. The situations I'm thinking about are: 1. axles in technic bricks, which fit your "no friction" model; 2. the light grey low-friction pins, which could also fit the "no friction" model (with regard rotation); 3. the (...)

(...) Well again BFC is only useful for culling surfaces that face away from you. It doesn't really do anything for faces that face you but are blocked by other faces. When I talked about top, left, right, etc, I was envisioning some system by which (...) (23 years ago, 11-Feb-02, to lugnet.cad.dev)

My classification into 5 possibilities was only meant to be an overview of what had been suggested so far, so that people could say what they were interested in. Personally I think there should be several programs, with separate code bases, and this (...) (23 years ago, 11-Feb-02, to lugnet.cad.dev.mac)

(...) Welcome in my brain, Barney: I was writing about gravity and inertia in this very hour. The approach you describe may be usable, but as for myself, I'm talking in the LMPL proposal about a tensile strength instead. I see some difference. (...) (23 years ago, 11-Feb-02, to lugnet.cad.dev.lcd)

I was thinking of friction as a simple on/off property: connections with friction only move during construction, whereas connections without are free to move under gravity or inertia or other forces during animation of the final model. Is this too (...) (23 years ago, 11-Feb-02, to lugnet.cad.dev.lcd)
