Hi everyone,

My lab is considering presenting 3D objects (e.g., .obj file with textures) with Psychtoolbox. According to some demos, I know PTB can do it, but I don’t know if there is any tutorial or guide that I can follow to have better control of the presentation. For example, how to move an object in 3D space, control light sources, etc.

If anyone can share any resources, I would really appreciate! 🙂

Thanks!  
Gabriel

Our demos like, e.g., `help MinimalisticOpenGLDemo` explain stuff in detail.

The classic intro into OpenGL is the “Red Book”, first release available online:  
[http://www.glprogramming.com/red/](http://www.glprogramming.com/red/)

Latter releases, covering OpenGL versions later than 1.1 in any good book store.

More tutorials etc. under [Getting Started - OpenGL Wiki](https://www.khronos.org/opengl/wiki/Getting_Started#Tutorials_and_How_To_Guides)
