Hi

What Doru wrote pretty much sums it up.

CodeCity under VW was based on JUN, which provided a programmer-friendly API built on top of OpenGL. Since there is no such thing under Pharo, when I later started to work on CodeCity under Pharo, I needed to learn about how to program directly to OpenGL. And the only example I had for that was SourceCity. In the meantime I manage to get a grip on my basic needs and was ready to move forward to implementing CodeCity. Now that does not work anymore in Pharo 3.0 so I am stuck. I could continue to program under Pharo 2.0, but what's the point?

I have already looked at Roassal 3d, but it was not easy to separate the API from the code. And it is something completely different than what I have been using (and SourceCity, too), because Roassal 3d is using the modern OpenGL methodology (with FBOs and stuff). So, I would really appreciate if that API would find its way from Roassal to NBOpenGL and I could use it for CodeCity. Unfortunately I am able to help a lot with that, because I know very little about this and I also don't have enough time (I am doing CodeCity in my spare time). But, if you have concrete things that I can do, I'd be happy to help.

Cheers
Ricky

Hi,

I guess that what Ricky is asking is what changed between NBOpenGL 2.0 and 3.0 such that this does not work anymore on Windows. The fact that he mentioned 64 bits is not relevant for this discussion :).

I also guess he wants to put some effort into understanding this as well but he needs a bit of guidance. Right Ricky?

Cheers,
Doru

you should have a look at ROASSAL 3d because ronie improved the shadder part (no more assembler)
and his code should be split in two and one part should go to NBOpenGL.
Now he is experiencing some problem with NBOpenGL on windows as you.

NativeBoost does not work on 64 bits. Yet but igor is really busy finishing the texteditor (and I can tell you that
he does not have fun there).

So it is important that you help because we are FULL
and sorry about that but really FULL.

Ronie will visit us in January and share an office with igor.
