comment Why did the old 3D games have “jittery” graphics?
To make this to statements about Q2 correct: Quake 2 uses perspective correct txt mapping for level geometry(linear interpolating every 16th correct calculated pixel) and affine textmapping for movable objects

comment unlimited (wraparound) 3d terrain
Aha.. thats interesting approach! I do not like the idea of moving all items through the chunks on moving forward(as this will not scale very good). But It is a first approach(I would like to have a geometrical approach, but thanks anyway!)

I am asking about drawing or better retrieving the list of items to draw(especially when I am near the edges of the wrap around)

comment unlimited (wraparound) 3d terrain
in 2D I render a 2D screen and can easily use modulo to check if I need to draw an item. In 3D I usually need to use frustum culling. I do not know how to wrap the frustrum around the terrains edges

comment 2D animation example in pyglet (python) looping through 2 images/sprites every x seconds
in update_frames(dt). I sum up the time between calls to this function and modulo it by 2 so it counts up to 1.999999 and then starts over on 0. If you want to have a duration of half a second add 2*dt. There is no flickering in my version .. could be an pyglet/driver issue
