Hello Triangle

This displays a spinning cube with different images on each side. This is intended to demonstrate OpenGL ES rendering. OpenGL is an open-source programming library for working with 3D graphics.

Enter the following commands to navigate to the hello_triangle folder and list its contents:

cd ..
cd hello_triangle
ls

You’ll see again that one of the files is green; this is the executable file as before. This demo doesn’t need any video input files like the previous one, so you can just go ahead and run the .bin file:

./hello_triangle.bin

The demo will run forever until you decide to quit. To exit the demo press Ctrl + C.
