CatRomSphere Processing code of spherical globe and circles of equal altitude. No special libraries needed. Move the vertical slider to adjust the altitude angle, move the horizontal slider to adjust the right ascension/longitude. It uses the processing function thread() to compute the points of the circle seperately from the draw() thread. This is a quick and dirty way of threading with the risk of inconsistent results. In other words, if it draws a mess, its because it uses thread() incorrectly. It now uses thread() correctly which means that if it is drawing then you cant rotate the globe. Rotating the globe does not cause it to redraw anymore. The only way to redraw is to change a slider.

The application.windows64 directory is a standalone export of the application. To use it, you dont need Processing, since the directory includes everything needed to run the program. Download that directory and click on the CatRomSphere.exe file.

IMPORTANT: This repository uses a vertical slider borrowed from a project written by someone smarter than me. I dont have a link but the following was in the header of the processing file:

/*

Kepler Visualization Tool [email protected] Spring, 2011 - released w/ new Data Spring 2012

This is a Processing sketch to visualize data from NASA's Kepler mission.

Obviously, you'll need Processing installed - http://processing.org

Space! Yay!
