Euler Angles and Quaternions Rotations

[OGLB]

Hello,
I hope you’re all doing well.
I’m a new member in this group and I’m also an OpenGL beginner.
I’m trying to create an application with Qt in which I can rotate my cube using Euler Angles and then quaternions but I’m facing a lot of problems.
I could render the cube with its fixed frame and I could rotate it using glRotate but I didn’t know how to use Euler Angles or Quaternions or how to implement them.

Can anyone provide me with some tips or tutorials please ?

This isn’t really an OpenGL question then. Grab a graphics math book or tutorial and read-up. Here are a few random hits:

• Quaternion Powers (by Sobeit Void, Version 1.2, 2/2003)
• Game Math: Quaternion Basics (by Ming-Lun “Allen” Chou, 4/2014)
• The Matrix and Quaternions FAQ (version 1.4, 12/98)
• Mathematics for 3D Game Programming and Computer Graphics, 3rd ed (by Eric Lengyel)
• Quaternion (by Wolfram Mathworld)

The last has a ton of quaternion-related cross-references at the bottom.
