I gave these files a try. The 3ds version is one of those that stores the diffuse color in a way that i was never able to read correctly. These files store the color in some undocumented way and i couldn't make any sense of it...which is why (at least the desktop version does this, not sure about AE) a message is logged to the console. However, i've exported the file from DeepExploration and that one can be read just fine.
About the OBJ-format: You can't load diffuse colors from that one without the mtl-file, so i couldn't try that.
I'll post the code for the test case for desktop jPCT and the converted file:
import com.threed.jpct.*;
public class HelloRoom {
private World world;
private FrameBuffer buffer;
private Object3D box;
public static void main(String[] args) throws Exception {
Config.glUseVBO=true;
new HelloRoom().loop();
}
public HelloRoom() throws Exception {
world = new World();
world.setAmbientLight(155, 155, 155);
box = Object3D.mergeAll(Loader.load3DS("lab.3ds", 0.05f));
box.rotateX((float)-Math.PI/2f);
box.compile();
box.build();
world.addObject(box);
world.getCamera().setPosition(50, -50, -5);
world.getCamera().lookAt(box.getTransformedCenter());
}
private void loop() throws Exception {
buffer = new FrameBuffer(800, 600, FrameBuffer.SAMPLINGMODE_GL_AA_2X);
buffer.disableRenderer(IRenderer.RENDERER_SOFTWARE);
buffer.enableRenderer(IRenderer.RENDERER_OPENGL);
while (!org.lwjgl.opengl.Display.isCloseRequested()) {
box.rotateY(0.01f);
buffer.clear(java.awt.Color.BLUE);
world.renderScene(buffer);
world.draw(buffer);
buffer.update();
buffer.displayGLOnly();
Thread.sleep(10);
}
buffer.disableRenderer(IRenderer.RENDERER_OPENGL);
buffer.dispose();
System.exit(0);
}
}
