Mario Meissner SOCIS 2017 Logs
10-8
Moving task over to rtexample. Including Voronoi tesselation. 0 and 1 points working, including user input (no hardcoded points).
11-8
Continued working on n-point Voronoi. Todays code doesn't compile yet.
12-8 & 13-8
Break.
14-8
Continue working on n-point Voronoi.
15-8
Finished initial Voronoi point implementation.
Will now continue working on implementing vectors.
16-8
Break.
17-8
Working on read_density_points to support vector input.
18-8
Finished read_density_points vector update and will now give support to transitions (vectors) with arbitrary 'rate' inside segment_density calculations.
Moved old logs to a separate page (http://brlcad.org/wiki/User:Mariomeissner/logs/old) to keep this one clean.
30-8
Left the code in a more stable shape. Fixed some bugs, projections are now skipping.
5-9
Finally set myself up in Germany. New objective: test out code and fix any more bugs. Took my time to set up dev environment, but couldnt work because of compilation issues.
6-9
Testing and fixing code. Found major flaw in projection skipping.
7-9
Worked on a new model to properly skip projections.
8-9
Implemented the new projection skipping model and re-ran the tests. Everything seems to work correctly for now.
9&10-9
Break
11-9
Cleaning code and moving over to rtweight. Once I moved I will run rtweight tests to see if mass is correctly computed for simple shapes.
12-9
Found some more mistakes in the code.
13-9
Preparing the move to rtweight.
14-9
Moving code to rtweight. It's harder than expected and things don't work yet. I tried cleaning out most of the code that was used to read densities from the file, and rely only on my own function call (so that I can avoid the stupid segmentation fault I can't get rid of).
15-9
Break.
16-9
Mass returns as NaN so something is wrong somewhere. Debugging.
17-9
Had several compilation problems. I can now compile on VS again. Density file loads. Mass now returns 0.
18-9
Break.
19-9
Investigating cause of negative densities that end up causing the final mass to be 0.
20-9 & 21-9
Because of course registration and orientation events, busy. Break.
21-9
Fixing code in rtweight.
22-9
Fixed several issues, mass now computes, but wrongly.
Trying to learn to use the VS debugger.
Starting to get a feel on why things don't work. I'm finding and polishing several issues. I also noticed that I am not correctly handling two edge cases for segment density:
-First point should be a skip (for now I had assumed first point would never be one, without really thinking about it).
-First bunch of points or last bunch of points' projections lay outside the segment. They should receive special consideration.
23-9
From today I will try to approach the final step of my code in a slightly different way, in order to correctly handle projections outside the segment, but who's boundaries actually lay inside. I will use intersections to compute a list of boundaries, and then just loop through them once to calculate avg density. I will not use the projection point in this stage (I will still use it to predict a skip).
24-9
