I had a go at converting the Python version with cylinders for branches to Lazarus OpenGL but I am not seeing the OpenGL fractal Tree. Only scattered colours. What could be the fault ?
Perhaps the fault has to do with the projection I am using. I Don't Know:
glMatrixMode(GL_PROJECTION);
glLoadIdentity;
gluPerspective(45.0, OpenGLControl1.Width / OpenGLControl1.Height, 0.1, 500.0);
