Rendering graphics on the TI-Nspire in C/C++ with Ndless as never be so easy!
hoffa’s SDL port nSDL and totorigolo’s nRGBlib were already available.
Now Levak brings nGC to the Ndless SDK. The “TI-Nspire Graphic Context” is a standard TI-Nspire API inspired by Java’s Graphics2D and based on Nucleus GRAFIX functions. If you have already developed Lua programs for the TI-Nspire the API will look very familiar to you.
Get Ndless and Ndless SDK >= r903, #include <ngc.h>, have a look at the API documentation, run the sample program in _samples/ngc/ and start to write your own colorful native programs now!

Great! This will make it easier for Lua programmers to create native programs.
