Yes, 3D model importing will work in the future versions.
It is just that this took a while because of the many vectors I had to deal with to make it such a simple function, or ogldrawcube, which works by the first 4 arguments being the sizes of the four sides of the cube.
Then, you can change the rotation, or angle argument, of the cube. The last argument is the color of the cube.
Now, I just have to make it so that you can import 3D models into DS App Studio and draw them in the application.
Right now, I am looking for a developer who would like to create a 3D modeler program that makes models, and then exports them as .bin.
Otherwise, I would recommend Blender as the program to use.
Here is the engine I am working on for DS App Studio. There will be a function called ogldrawmodel(name of the model in quotes)
Edit: I don't think the Nintendo DS uses any other renderer, but I was thinking about making the renderer something more advanced then OpenGL. The only limitation that would prevent advancement is the graphics of the Nintendo DS is very "poor" compared to other systems. Once I get DS App Studio homebrew compatible for the Nintendo DSi, the graphics will be better.
Besides graphics, I may be adding WIFI functions that will allow people to view webpages on the Nintendo DS using the wfiloadURL(address of URL);
The thing is, the Nintendo DS may need a Nintendo DS WIFI service in order to do this.
