I created some code to parse .OBJ files and I have all the vertex, face, and UV data stored in arrays.
Not I would like to display a mesh with OpenGL. But when searching for info, most people point to www.xojo3d.com .
However, that site is not working. Is there any other place where I could get information about OpenGL in Xojo?
That page directs me to the Red Book page. However, that page has all the code expressed in C (or C++).
I know I can easily translate most of the code to Xojo, but most of the examples are generic.
For example, I do have all the necessary vertex, face, uv information available. But I can’t seem to be able to draw any polygons. It only shows me a black rectangle.
I was hopping to be able to see actual Xojo examples, that is why I was eager to see what was on the “deceased” Xojo3D.com site.
i made something with opengl a few years ago, maybe you get examples from there.

i remember this xojo opengl was very very out of date … (not for deploy an 3d app with)

Thank you, MarkusR.
I requested access to the project. I hope I can see how it draws 3D surfaces 
ups
now this xojo project download should be public for all without need for an account.
Thank you very much
WOW!!! Very nice. I have a lot to dissect, but I will love to do it.
This seems like it will help me a lot. Once again, thank you.

There is also a book that has explanations and examples.

I believe there is Xojo API 1 code in this book.
GREAT!!! Thank you so much!!
