Using Arrow keys in OpenGL

OpenGL OpenGL: Basic Coding
1

Hello, i’m relatively new to opengl but am taking a graphics class to learn more.

anyway, right now the program i’m working on displays a picture, then allows the user to pan left, right, up, and down, and also zoom in and out using letters on the keyboard.

i would like to use the arrow keys instead of letters.

perhaps there is an ascii value i do not know?

i spose this relates to all c++ programming. but if you have any insight let me know.

Arrow keys are not part of ascii.

Arrow keys are even not part of OpenGL :wink:
If you happen to use GLUT, have a look here for the constants defined for left/right keys etc:

Else, well go see the doc of the API you use for testing keyboard key presses (and not ASCII values).

Thanks. i got it to work using GLUT as you suggested.
