Description: ROAM Simplistic Implementation
By Bryan Turner
brturn@bellsouth.net
January, 2000
Project file for MS Visual C++ 6.0.
Requires GLUT DLL (www.opengl.org)
Adjust program constants in Landscape.h and Utility.cpp.
MAPS:
Default map is read from HeghtXXX.raw where XXX is the MAP_SIZE
(as defined in Landscape.h). If this map is not found, the program
attempts to open \"Map.ved\", a Tread Marks map file. Tread Marks maps
will only work for MAP_SIZE == 1024. Also, the MULT_SCALE to view
Tread Marks maps correctly is \"0.25f\". (www.TreadMarks.com)
CONTROLS:
MOUSE - Hold Left Mouse Button to Rotate View Angle
Q - Change Rendering Mode (Wireframe, Lit, Fill, Texture)
O - Change View Mode (Observe, Follow, Drive, Fly)
W/S - Move forward/back
A/D - Rotate left/right (in Observe Mode only)
F - Stop Animation
R - Toggle Frustum Drawing
0/9 - More/Less Triangles per frame
1/2 - Adjust FOV
