game engine: nodetree/frustum technique and simple fog

not the best algorithm or implementation on the code but somehow it works for me. as for fog, clearly i'm suck at playing with the settings. anyway here is the screenshot.



i'm using octree optimization. i'm planning to try ray tracing / object selection using mouse coordinates but i need to use more time on nodetree technique until i'm comfortable with it.

if you're curious what guide am i using on creating this engine... jim adam's programming rpg game 2nd ed! try this one if you're a total newb on directx like me. this book actually got some bad reviews on non-working codes? i feel bad for them... for crying out loud *it's in the book, not in the source!*.

cheers =D
