R112: Labels

Star labels added in R112: this is intended to be the last cosmetic fix before a general "refactoring" phase preparing for:
  1. synergic mergers of similar structures according to C object orientation techniques – perusing similarities in struct declarations using a type tag and perhaps a virtual table implementation providing real dynamic method dispatch, such as generally invisible in C++
  2. thereafter program loading and map setup.
I would have liked to sprinkle my star maps to Wikipedia sites (and Citizendium where there are no images at all), but it won't happen before program loading becomes beta and so mkmap becomes alpha.

R111: Delporte 1930 area

Constellation Orion again: darker background for the Delporte 1930 constellation area. This was accomplished in R111 of Mar 5, 2011.

A note on Streaming theory – r87: that theory is dead and buried — mkmap cannot use streams because loaded data is reused again and again, and some loaded data peruses earlier loaded data. No streams, but instead database like queries.

R107 — R110: Constellations and asterisms

The maps that were exhibited in posting "Example maps" were generated from R110 adding Constellation bounds. Revisions from R106:

  • R107 (Feb 8, 2011): ripout of star struct into star.[ch],
  • R108 (Feb 17, 2011): microscopic struct attribute and function renames,
  • R109 (Feb 26, 2011): adding asterism line drawing,
  • R110 (Mar 3, 2011): adding code for loading and drawing constellations' bounds.
The project is as alive as possible, given the current life conditions. I'm doing "practice work" in my church¹), full time, and some voluntary works at that church in the evenings, whenever I'm not applying for jobs that none is going to give me. This blog and the sternons project is designed to be a "job application merit", but it doesn't matter, because I'm 50 years old and nobody in Sweden is going to employ me anyways ²). My real purpose with this blog and the project are the star maps, just the star maps ... and to whatever use one may put star maps ...

¹)Willingly: it's my church, just not the nearest church.
²)Capitalism sucks, truly: any system that refuses to employ a well educated healty computer engineer with full working capacity under a hot boom when there's a shortage of computer engineers, is a sociopathic system (I'm hereby mild and reconsiling).

Example maps

Monoceros, a constellation that formally is overlapping the galactic equator but still pretty devoid of bright stars like the neighboring Orion. Lot's of deep-sky objects, most prominently the Rosette Nebula near the "head", and the sparse but bright open cluster NGC 2244 that have blown up a cavity in this HII bright nebula, which is excited by the hot young stars of that open cluster.

The constellation seems to have been formed from stellae informata by Petrus Plancius near the turn of the 16th to the 17th century.
Orion is the heavenly hunter that boasted that he could kill every possible animal on this planet. Gaia, Mother Nature, then became pretty upset, and sent the Scorpion to kill the blasphemer.

Orion the constellation is in direction of a real star craddle of Milky Way. Young bright stars are numerous. M42 and M43, the Orion nebula is part of one of the most studied star formation areas of the heaven, containing protoplanetary disks and young protostars cocooned in dust and dark hydrogen gas and thence only visible in the IR range of electromagnetic radiation.
