bug fix: re-entering functions loses if/else state
bug fix: more issues with low-resolution linear-z index lines.
Need to compromise for isosurfaces and nucleic cartoons
-- which became very slow to render with precision Z placement.
The second fix there is in relation to a subtle mistake that Jmol's
renderer makes in calculating the z position of a pixel in perspective
mode. In particular, the calculation across a line in space is *not*
linear -- it is a curve. This is now fixed,
but I needed to make some performance compromises in JavaScript such that
it is not implemented with isosurfaces or nucleic acid bases. This seems
reasonable because those typically involve hundreds or thousands of small
triangles, and this only appears significant with long lines or large
triangles.
The first bug fix is for Rolf -- recursive function calling was losing
if/else references. Just a very simple fix. So now Jmol functions are fully
recursive.
Example:
maxLevel = 3
function recTest(level, indent) {
print indent + level + " entry";
for (var i = level; i < 3; i++) {
print indent + level + " for i=" + i;
if (level < maxLevel) {
print indent + level + " if " + level + " < " + maxLevel + " enter "
+ (level + 1);
recTest(level + 1, indent + " ");
} else {
print indent + level + " else ";
}
print indent + level + " continuing for i=" + i;
}
print indent + level + " returning";
}
recTest(1, "");
1 entry
1 for i=1
1 if 1 < 3 enter 2
2 entry
2 for i=2
2 if 2 < 3 enter 3
3 entry
3 returning
2 continuing for i=2
2 returning
1 continuing for i=1
1 for i=2
1 if 1 < 3 enter 2
2 entry
2 for i=2
2 if 2 < 3 enter 3
3 entry
3 returning
2 continuing for i=2
2 returning
1 continuing for i=2
1 returning
