REFRACTION branch:
Introduces changes necessary for refraction and extinction effects.
Status: Partial solution, needs help.
Contributor: Georg.Zotti@univie.ac.at
All changes are donated to the Stellarium project for distribution under opensource licenses like GNU.
COMPUTING: core/RefractionExtinction. DONE
STARS: core/modules/ZoneArray::draw
BUG: stars appear to have a problem after magnitude loss.
+SELECT-MARK: StarMgr.cpp::drawPointer(). DONE
CLICK-IDENTIFY: core/StelObjectMgr::cleverFind(core, x, y) DONE
INFOSTRING: core/StelObject.cpp::getPositionInfoString(core, flags) DONE
new core/StelObject.cpp::getSideralPosRefr(core) DONE
DEEPSKY: NebulaMgr::draw(). Influences symbols and labels only.
+DSO TEXTURES: ---TODO. May require a vertex shader program, beyond my knowledge.
+SELECT-MARK: NebulaMgr::drawPointer(). DONE
+MILKY WAY: Should become dimmer in low sky. May require a vertex shader program, beyond my knowledge.
PLANETS: ---TODO. Involves StelPainter, 3D spheres, full matrices.
May require a vertex shader program, beyond my knowledge, sorry.
+SELECT-MARK: SolarSystem::drawPointer. DONE
RA-DEC+GAL.GRIDS: core/GridLinesMgr. TODO OR LEAVE-AS-IS
Requires changes in StelPainter's arc drawing methods.
Currently this seems not viable and will not be changed.
SATELLITES: Not required, practically unobservable on horizon, orbital parameters unsure, etc.
Should be easy, however.
CONSTELLATIONS: Large-scale items. Vertices could be refracted. Extinction would be a nice effect.
Not urgent, later.
METEORS NOT NECESSARY.
OTHER? ???
CHANGES IN LANDSCAPE HANDLING:
1) Moved config.ini:[stars].init_bortle_scale to [landscape] section
2) Added optional settings to landscape.ini files:
landscape.ini:[location].light_pollution (<1: no change; 1..9: Bortle; >9-->9);
landscape.ini:[location].display_fog: -1=no change, 0=off, 1=on
landscape.ini:[location].atmospheric_extinction_coefficient (mag/airmass; -1=no change)
landscape.ini:[location].atmospheric_temperature (C; -1000=no change)
landscape.ini:[location].atmospheric_pressure (mbar; -1=auto, <-1 no change)
LandscapeMgr forwards those settings to the respective recipients.
TODO: make GUI aware of changed values (how?).
GUI changes: ViewDialog.ui
added 3 DoubleSpinBoxes for temperature, pressure, extinction coefficient into atmosphereGroupBox
ViewDialog.cpp: TODO: when switching landscapes, new data only load partially into GUI. No idea why!
CHANGES IN ASTR.COMPUTATIONS
planetsephems/sideral_time.[hc]: added get_mean_ecliptical_obliquity(double JDE),
changed correct ecliptic in nutation computation.
StelUtil::ctRadec2Ecl(): coordinate transformation RA/dec to ecliptical with given ecl. obliquity.
Planet::getInfoString(): added ecliptical positions for planets if observed from earth.
This helped detect A BUG, apparently ecliptical obliquity does not change, currently.
