3d Viewer renderer

I want to have an application created like this "http://www.quick3d.org/" The one that I am interested in is the viewer. I do not need everyhting this one has nor does it do everything I want my app to do. Please message and I will try to explain. It would be helpful if you have experience writing rendering software. Examples help me to decide. Give me a quote in pm i am sure that it can not be done for 100
