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
