Instance based random buildings
Replace random buildings with one using proper instancing. Also implement more control over rendering of random buildings. see README.scenery for details.

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.
