- Implemented soft shadows using PCF hardware shadow mapping
The implementation uses sampler2DArrayShadow and PCF which usually
requires Direct3D 10.1 however it is in the OpenGL 3.2 core so it should
be widely supported.
All 3 light types are supported which means parallel lights (sun) use
scene independent cascaded shadow mapping.
The implementation is very fast with single taps (400 fps average per
scene on a GTX 660 ti OC) however I defaulted it to 16 taps so the shadows look
really good which should you give stable 100 fps on todays hardware.
The shadow filtering algorithm is based on Carmack's research which was
released in the original Doom 3 GPL release draw_exp.cpp.
- Changed interaction shaders to use Half-Lambert lighting like in HL2 to
make the game less dark
- Fixed some of the renderer debugging/development tools like r_showTris
D3BFG gets the username from Steam, in the GPL release it just
uses the hostname.
Now it's possible to set a custom name with the ui_name CVAR
(like in classic doom3). If ui_name is empty ("") the hostname
is used.
The window losing focus in MP resulted in the console being spammed
with "changing com_pause not allowed in Multi Player" (or similar)
messages. Added CVAR_NOCHEAT flag to com_pause to get rid of that.
If the window loses focus com_pause is set to 1, when it regains focus
it's set to 0.
The behaviour on Win32 stayed the same (the implementation is less
hacky though) and Linux now matchces that.
