Hi! I'm trying to build a molecular viewer with pyglet and I'm currently
hitting performance problems but I can't figure out how to solve them.
My test case contain 7 cylinders (100 triangles each) and 6 spheres (200
triangles each). For each shape (13), I generate triangle vertices and
normals and store those in numpy arrays. At the moment of rendering I use a
call like this:
draw(n, pyglet.gl.GL_TRIANGLES,
("v3f", self.tri_vertices),
("n3f", self.tri_normals),
("c3B", self.tri_color))
I run a little test that simply rotates the camera, FPS are ~2. From the
profiler output, sorting by time (time spent in the function, without
subcalls):
ncalls tottime percall cumtime percall filename:lineno(function)
7605 56.375 0.007 56.529 0.007

/usr/lib/pymodules/python2.7/pyglet/gl/lib.py:85(errcheck)
It seems that most of the time is spent in the set_region function but I'm
not sure how to solve this problem. What do you think it's going on?
