PRIORITIES FOR SECOND CONTRACT

Priorities are in the range [0,5] with 5 being the highest and 0 the lowest.


ACCEPTED:


COMPLETED:

- Wireframe toggle for water surface only, 'w' key [4]
- Ability to compile from arbitrary location (e.g. using environment variables) [4]
- Correct scaling and origin for datasets not centered at (0,0)? [3]
- Reference horizon (possibly sky) as visual aid to orient scene [5]
- Compilation under Mac [1]
- Culling of triangles [5]
- Use per-vertex normals for reflection of light [4]
- Ability to automatically produce distro (win32) [4]
- Texture mapped water surface [2]
- Texture mapped topography [4]


UNDER DEVELOPMENT:

- Output coordinates defining camera position [5]
- Interactive positioning of light(s) [4]
- use of geotiff in sww file [?]
- Optional height-dependent colour coding of water surface [4]


BUG LIST

- cairns dataset reveals popping triangles (zbuffer?)
- steepcull dataset reveals steep angle cull problem
- nonuniform scaling into unit cube should be uniform


BUGS FIXED:

- onscreen text no longer obscured by zoomed model
- removed lighting from onscreen text, now constant colour
- memory leak occurring when loading subsequent stages fixed by use 
  of ref_ptrs in SWWReader
