Hi,

how to insert JPEG on each side of the cube using OpenGL in C language..
i have a program for cube..

guide me ,,,
any answer will valuable..

Please read the The UNIX and Linux Forums - FAQ

and do not multiple/cross post.
how to insert JPEG on each side of the cube using openGl

What have you tried so far...where is it failing. Posting code is more likely to get you an answer than an open question.

Hi,

The below code is working and it generate a cube which is rotating...

i need to insert JPEG on each side of the rotating cube...

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.
