So, I've been thinking about how to start a PVS implementation, and it essentially amounts to something like this:
For each base octree node/spatial grid cube . . .
For each of 6 camera view frustum directions . . .
Render each individual triangle wrapped in an occlusion query . . .
If the triangle passes, then add it to the list of "visible triangles" in that 1/6 frustum section for that octree node/spatial grid cube
Then. . . during runtime, determine which octree node/spatial grid cube the camera is in... intersect the camera frustum with the 6 view directional frustums to get (i guess) at most which 3 frustums are potentially visible, then render all triangles in the "visible triangles" lists of the frustums which are intersected . . .
Feedback appreciated, please especially post any good PVS implementation related material you may have.
