PRIORITIES FOR SECOND CONTRACT

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


ACCEPTED:

- Wireframe toggle for water surface only, 'w' key [4]
- Reference horizon (possibly sky) as visual aid to orient scene [5]
- Use per-vertex normals for reflection of light [4]
- Correct scaling and origin for datasets not centered at (0,0)? [3]
- Texture mapped topography [4]
- Culling of triangles [5]         


ACCEPTED IN PRINCIPLE (STILL NEED TO BE VERIFIED):

- Compilation under Mac [1]
- Ability to automatically produce distro (win32) [4]
- Ability to compile from arbitrary location (e.g. using environment variables) [4]
- Texture mapped water surface [2] (Not the same as the reflection?)


COMPLETED:





UNDER DEVELOPMENT:

- use of geotiff in sww file [5]
- Optional colour coding of water surface based on arbitrary fields 
  (e.g. stage, speed, ..) [4]
- Ability to remove light source (it's in the way sometimes) [2]  
- Output coordinates defining camera position [?]
- Interactive positioning of light(s) [1]



BUG LIST

- cairns dataset reveals popping triangles (zbuffer?)
- steepcull dataset reveals steep angle cull problem
- nonuniform scaling into unit cube should be uniform
- dragging sww onto swollen (all in one directory) does not produce the same results as calling from command line (All jpg's gone and no reflection)
- Problems with Duncan's, Chris' and Stephen Roberts' machines at GA: Swollen won't render semi transparency. Swwiewer works fine.
- Swollen starts up showing first time step, not zeroth (even though clock shows zero). Stepping one forward and one back, bring things into sync.



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




--------------------------------------------------

APPEARANCE:

- Scene augmentation with OSG models [2]        
- Optional contour lines of water surface [1]
- z-scaling to emphasize vertical details [1] 
- Optional height-dependent semi-transparent water surface [0]
- Possibility of replacing graphics for bed-texture [2]
        

FUNCTIONALITY:

- Ability to read from file as it is being produced (like tail -f) [3]
- Ability to output frames in a common image format for making standalone animation [3]
- Input camera position to give desired view [2]
- Return to home view [2]
- Start up with a view sight from above rather than from the side [2]
- Movement restricted to within bounding sphere [1]
- Command line parameters for culling, speed [1]
- Optional colour coding for momentum [0] (Superseded)  
- Ability to show earthquakes [0]
- Concept of 'buildings' and shaking them [0]




OPTIMIZATION:

- Scene optimization via geometry and texture level-of-detail (LOD) [3]
- Ability to handle scenes with a resolution of 500,000+ triangles [3]
- Separate thread for loading a ring buffer of stage data [1]


COMPILATION:

- Ability to automatically produce distro (linux) [4]
- Compilation under Linux [3]
- Ability to compile using gnu gcc/g++ [3]


OTHER:

- Brief documentation of interface [4]
- Revisit use of culling steep epsilon [3]      
- SWW netcdf meta information [0]
