Don't include the lazy precompiled.h everywhere, only what's required for the compilation unit. platform.h needs to be included instead to provide all essential defines and types. All includes use the relative path to the neo or the game specific root. Move all idlib related includes from idlib/Lib.h to precompiled.h. precompiled.h still exists for the MFC stuff in tools/. Add some missing header guards.

Trace model vs. polygonal model collision detection.
|
|
|
|
Short translations are the least expensive. Retrieving contact points is
|
|
about as cheap as a short translation. Position tests are more expensive
|
|
and rotations are most expensive.
|
|
|
|
There is no position test at the start of a translation or rotation. In other
|
|
words if a translation with start != end or a rotation with angle != 0 starts
|
|
in solid, this goes unnoticed and the collision result is undefined.
|
|
|
|
A translation with start == end or a rotation with angle == 0 performs
|
|
a position test and fills in the trace_t structure accordingly.
