Ok, here's another newbie question... Can I draw 2D objects within my 3D-based scene? I'd like to draw cartesian coordinates among my objects... and of course those grid lines aren't really 3D objects but rather drawing artifacts within a 3D scene... Still I'd like the grid to obey (at the very

Just my 2 cents to that: Build your cylinder so that the axes is along the negtive z axis with the center of the bottom base at (0,0,0) and the center of the top base at (0,0,-length). Then use the inverse transformation generated by the lookAt method with the 2 points which define the position

Have attached modified code... (look for // MOD GF for changes.) Main change, your angle calc was the difference between the two point vectors. This needed to change to be the angle between the cylinder axis and the new axis, (see the second attachment) and subsequently the orthagonalAxis change

Man... I can't believe I wrote that slop. If you run the test program I just posted, you will see a cylinder object rooted at the origin of the scene and a sphere. All well and good, but the cylinder ends out in free space someplace. It should connect to the blue sphere, but its pointing off in

All, I'm trying to connect the dots with cylinder objects but can't quite get it right. The endpoints of the cylinder should connect to two of the spheres, but clearly this isn't happening. The meat of the issue is in the method "makeConnector". My suspician is that since I do the rotation tr
