Doom3 maps are in text format rather than a compiled format like in previous id games. a .map format from gtkradient looks like follows:

Code:
  1.  
  2. // entity 0
  3. {
  4. "classname" "worldspawn"
  5. // brush 0
  6. {
  7. ( -200 216 264 ) ( -200 208 264 ) ( -200 208 256 ) chateau/wood_c06 -48 144 0 0.500000 0.500000 0 0 0
  8. ( 8 224 264 ) ( -200 224 264 ) ( -200 224 256 ) chateau/wood_c06 16 144 0 0.500000 0.500000 0 0 0
  9. ( 136 88 264 ) ( 136 96 264 ) ( 136 96 256 ) chateau/wood_c06 -48 144 0 0.500000 0.500000 0 0 0
  10. ( -88 -104 264 ) ( 120 -104 264 ) ( 120 -104 256 ) chateau/wood_c06 16 144 0 0.500000 0.500000 0 0 0
  11. ( -200 208 264 ) ( -200 216 264 ) ( 8 216 264 ) chateau/wood_c06 16 48 0 0.500000 0.500000 0 0 0
  12. ( 8 216 256 ) ( -200 216 256 ) ( -200 208 256 ) chateau/wood_c06 16 48 0 0.500000 0.500000 0 0 0
  13. }
  14. // brush 1
  15. {
  16. ( -704 384 -8 ) ( -824 384 -8 ) ( -824 256 -8 ) chateau/marblefloor_c04 -16 128 0 0.500000 0.500000 0 0 0
  17. ( -824 256 0 ) ( -824 384 0 ) ( -704 384 0 ) chateau/marblefloor_c04 -16 128 0 0.500000 0.500000 0 0 0
  18. ( -392 64 0 ) ( -272 64 0 ) ( -272 64 -8 ) chateau/marblefloor_c04 -16 0 0 0.500000 0.500000 0 0 0
  19. ( -192 72 0 ) ( -192 200 0 ) ( -192 200 -8 ) chateau/marblefloor_c04 -128 0 0 0.500000 0.500000 0 0 0
  20. ( -704 384 0 ) ( -824 384 0 ) ( -824 384 -8 ) chateau/marblefloor_c04 -16 0 0 0.500000 0.500000 0 0 0
  21. ( -824 384 0 ) ( -824 256 0 ) ( -824 256 -8 ) chateau/marblefloor_c04 -128 0 0 0.500000 0.500000 0 0 0
  22. }
  23. // brush 2
  24. {
  25. ( -824 64 0 ) ( -824 -64 0 ) ( -824 -64 -8 ) chateau/marblefloor_c04 0 0 0 0.500000 0.500000 0 0 0
  26. ( -704 64 0 ) ( -824 64 0 ) ( -824 64 -8 ) chateau/marblefloor_c04 -16 0 0 0.500000 0.500000 0 0 0
  27. ( -192 -248 0 ) ( -192 -120 0 ) ( -192 -120 -8 ) chateau/marblefloor_c04 0 0 0 0.500000 0.500000 0 0 0
  28. ( -392 -256 0 ) ( -272 -256 0 ) ( -272 -256 -8 ) chateau/marblefloor_c04 -16 0 0 0.500000 0.500000 0 0 0
  29. ( -824 -64 0 ) ( -824 64 0 ) ( -704 64 0 ) chateau/marblefloor_c04 -16 0 0 0.500000 0.500000 0 0 0
  30. ( -704 64 -8 ) ( -824 64 -8 ) ( -824 -64 -8 ) chateau/marblefloor_c04 -16 0 0 0.500000 0.500000 0 0 0
  31. }
  32.  
  33. Etc....
  34.  


Each line holds the information for 1 tryangle, it also tells the program the texture cordinates, scale and rotation. But a doom 3 map looks like follows:

Code:
  1.  
  2. Version 2
  3. // entity 0
  4. {
  5. "classname" "worldspawn"
  6. "call" "map_marscity2::main"
  7. // primitive 0
  8. {
  9.  brushDef3
  10.  {
  11.   ( 0 0 -1 184 ) ( ( 0.03125 0 0 ) ( 0 0.03125 0 ) ) "textures/common/player_clip" 0 0 0
  12.   ( 0 0 1 -344 ) ( ( 0.03125 0 0 ) ( 0 0.03125 0 ) ) "textures/common/player_clip" 0 0 0
  13.   ( 0 -1 0 -2944 ) ( ( 0.03125 0 0 ) ( 0 0.03125 0 ) ) "textures/common/player_clip" 0 0 0
  14.   ( 1 0 0 2928 ) ( ( 0.03125 0 0 ) ( 0 0.03125 0 ) ) "textures/common/player_clip" 0 0 0
  15.   ( 0 1 0 2908 ) ( ( 0.03125 0 0 ) ( 0 0.03125 0 ) ) "textures/common/player_clip" 0 0 0
  16.   ( -1 0 0 -2970 ) ( ( 0.03125 0 0 ) ( 0 0.03125 0 ) ) "textures/common/player_clip" 0 0 0
  17.  }
  18. }
  19. // primitive 1
  20. {
  21.  brushDef3
  22.  {
  23.   ( 0 0.7739573121 -0.6332377791 1451.9439697266 ) ( ( 0.03125 0 0 ) ( 0 0.03125 0 ) ) "textures/common/player_clip" 0 0 0

  30.  }
  31. }
  32.  
  33. Etc....
  34.  


which at fist glance looks pritty similer, but the first line has 4 numbers. The first 3 might be normals? and the last number looks like it is added to the next 2 sets of 3 to gave them a position. Looking at it it looks like each line contains 2 vertex positions. But if each holds 2 vertex's wouldn't there not be enough information?

Im guessing when the map is loading u would also have to work out map clustors and which can see what.

Thoughts?

EDIT: looks like the AAS4B holds the info needed for working out what is visible, planes, nodes, clusters, etc. Its in text format too...

The three points in the q3 map file describe a plane and not a triangle. In the doom3 map the four values are from the plane equation. The first three numbers define the normal and the last is the distance from the origin.

do u know how to work out the vertex cordinates for each "primitive" ? (doom 3)
