Dear Sir.
I've finished very similar job yesterday.
You can see a project "Create Vision 3D on Macbook" on my work history.
I used OpenGL library for this job.
Your job is very easy for me.
I can finish it in a day. If they have no experience in OpenGL, they will face many issue.
Because OpenGL is just cross-platform library, it involves many issues.
But I have rich experience in developing 3D application by using OpenGL library.
Please give me a chance to work with you.
Thanks
