Do some intersection tests on the CPU so that the silhouette render
passes only have to draw models/patches that might actually contribute
to silhouettes, saving the CPU and GPU cost of rendering more objects
than necessary.
This was SVN commit r15483.
this snowballed into a massive search+destroy of the hodgepodge of
mostly equivalent types we had in use (int, uint, unsigned, unsigned
int, i32, u32, ulong, uintN).
it is more efficient to use 64-bit types in 64-bit mode, so the
preferred default is size_t (for anything remotely resembling a size or
index). tile coordinates are ssize_t to allow more efficient conversion
to/from floating point. flags are int because we almost never need more
than 15 distinct bits, bit test/set is not slower and int is fastest to
type. finally, some data that is pretty much directly passed to OpenGL
is now typed accordingly.
after several hours, the code now requires fewer casts and less
guesswork.
other changes:
- unit and player IDs now have an "invalid id" constant in the
respective class to avoid casting and -1
- fix some endian/64-bit bugs in the map (un)packing. added a
convenience function to write/read a size_t.
- ia32: change CPUID interface to allow passing in ecx (required for
cache topology detection, which I need at work). remove some unneeded
functions from asm, replace with intrinsics where possible.
This was SVN commit r5942.
- remove headers always included from PCH
- nommgr.h is only included ifdef REDEFINED_NEW (allows leaving out the
mmgr stuff)
- in lib/*.cpp, moved the corresponding include file to right behind the
PCH (catches headers that aren't compilable by themselves)
- byte_order no longer depends on SDL
- add debug_level (another means of filtering debug output; needed for
thesis)
- split posix stuff up into subdirs (lib/posix and sysdep/win/wposix).
makes including only some of the modules (e.g. sockets, time) much
easier.
This was SVN commit r4728.
- g_Terrain and g_Camera totally eradicated as globals, is now m_Terrain
of CWorld and m_Camera of CGameView
- terrainMain.cpp is almost completely empty with functionality moved
into the relevant core classes
- Miscellaneous global functions moved into Core Classes (mostly
GameView)
This was SVN commit r865.
