This file does most of the low-level rendering.

// rendergl.cpp: core opengl rendering stuff

Things Implemented HereEdit

Beside many very basic stuff there are some functions especially needed when modding the game graphics: Icons above players' heads

void renderaboveheadicon(playerent *p)
  • Draws those icons appearing above players, like this one

FOV and camera

  • Various functions, including "death cam"

Reflection and refraction

void drawreflection(float hf, int w, int h, float changelod, bool refract)
  • Mostly for water sfx

Minimap

void drawminimap(int w, int h)

Various HUD gun stuff

float zoomfactor(playerent *who)
  • Sets the zoom factor depending on the weapon type

Main rendering function

void gl_drawframe(int w, int h, float changelod, float curfps)
  • Does most of the "magic" (partly by calling functions from above), especially:
    • Underwater effects 
    • Fog
    • Shadows (by calling function from other file)
  • The place to go for most "core" graphics mods
