@ -400,6 +400,25 @@ See README.materials for details on configuring the random building parameters.
The referenced <filename> (in the example buildings.txt) contains lines of the form
X Y Z R B W D H P S O F T
Where:
- X,Y,Z are the cartesian coordinates of the center of the front face. +X is East, +Y is North
- R is the building rotation in degrees centered on the middle of the front face.
- B is the building type [0, 1, 2] for SMALL, MEDIUM, LARGE
- W is the building width in meters
- D is the building depth in meters
- H is the building height in meters, excluding any pitched roof
- P is the pitch height in meters. 0 for a flat roof
- S is the roof shape (currently unused - all roofs are flat or gabled depending on pitch height) :
0=flat 1=skillion 2=gabled 3=half-hipped 4=hipped 5=pyramidal 6=gambled
7=mansard 8=dome 9=onion 10=round 11=saltbox
- O is the roof ridge orientation (currently unused, all roofs are assumed orthogonal) :
0 = parallel to the front face of the building
1 = orthogonal to the front face of the building
- F is the number of floors (integer)
- T is the texture index to use (integer). Buildings with the same T value will have the same texture assigned. There are 6 small, 6 medium and 4 large textures.
