Using bounding box boolean to create a random 'subtraction' effect. Applied to a pretty standard octree scene management system.
What's happening is basically the program is 'cutting' into the objects in the scene and generating new replacement parts (new bounding boxes)
The goal of this test is to just make sure the logic is sound.. not very efficient.
I came across this little snippet of code* to find the next power of 2 and found it quite helpful – from what I understand it's also very efficient compared to other methods.
public int NextPowerOfTwo(int inInt)
inInt = ( inInt >> 1 ) | inInt;
inInt = ( inInt >> 2 ) | inInt;
inInt = ( inInt >> 4 ) | inInt;
inInt = ( inInt >> 8 ) | inInt;
inInt = ( inInt >> 16 ) | inInt;
inInt++; // Val is now the next highest power of 2.
