[915] | 26 | * x Convert to Tcl_CmdObj interface. (done) |
---|
[887] | 27 | * o Use Tcl command option parser to reduce size of procedures, remove |
---|
[915] | 28 | * lots of extra error checking code. (almost there) |
---|
[887] | 29 | * o Convert GetVolumeIndices to GetVolumes. Goal is to remove |
---|
[1089] | 30 | * all references of Nanovis::volume[] from this file. Don't |
---|
| 31 | * want to know how volumes are stored. Same for heightmaps. |
---|
| 32 | * o Rationalize volume id scheme. Right now it's the index in |
---|
[887] | 33 | * the vector. 1) Use a list instead of a vector. 2) carry |
---|
| 34 | * an id field that's a number that gets incremented each new volume. |
---|
[1282] | 35 | * x Create R2, matrix, etc. libraries. (done) |
---|
| 36 | * o Add bookkeeping for volumes, heightmaps, flows, etc. to track |
---|
[923] | 37 | * 1) id # 2) simulation # 3) include/exclude. The include/exclude |
---|
| 38 | * is to indicate whether the item should contribute to the overall |
---|
| 39 | * limits of the axes. |
