I’m trying to create a tree model using L-system and OpenGL/C++. What I did was instanciating a series of tapered cylinders in a tree shape. I achieved this through popping and pushing into position matrix. But the final product has unpleasant looking joints. I wanna smooth out the connecting joints and make them look less obtrusive. Any ideas would be greatly appreciated.
If performance is not important, maybe putting spheres at the end of the cylinders might work.
