Loading a 3ds file from Blender
Loading a 3ds file from Blender is fairly straight forward. Below is a quick model which I made and did a simple texture on. If the image texture window is used during texturing the coordinates and name will be exported. The name needs to be 8 characters with three for the extension or some characters will be cut off and it will be harder to load into Jpct. It's a good idea to select all the vertices and hit cntrl-t after making your model in order to export triangles. I have exported quads and they have worked so far, however. I switch to object mode before I export. Then Hit File->export->3ds. I named this character bman and texture is called bman.jpg.
Now we can load it into a modified version of the Hello World program. Notice that the texture is loaded first. Also notice the loadmodel function which does a bunch of things, which are pretty much standard I guess, except for the rotations which are used to orient the blender model in the same way it was in Blender.
