Hello,
I have started learning about jpct-ae.
At first I try to load 3ds model which does not have any texture.
I have modified jpct example code.
But it doesn't work...
My code is follow
package com.threed.jpct.example;
import java.io.*;
import java.lang.reflect.Field;
import javax.microedition.khronos.egl.EGL10;
import javax.microedition.khronos.egl.EGLConfig;

private String thingName = "temp";

private static HelloWorld master = null;

if (master == null) {

world.setAmbientLight(150, 150, 150);

} else {

} catch (Exception e) {

}
}
private Object3D loadModel(String filename, float scale) {
assMan = getResources().getAssets();
is= new InputStream() {
@Override
public int read() throws IOException {
return 0;
}
};
Object3D[] model = Loader.load3DS(is,scale);
Object3D o3d = new Object3D(0);
Object3D temp = null;
for (int i = 0; i < model.length; i++) {
temp = model[i];
temp.setCenter(SimpleVector.ORIGIN);
temp.rotateX((float)( -.5*Math.PI));
temp.rotateMesh();
temp.setRotationMatrix(new Matrix());
o3d = Object3D.mergeObjects(o3d, temp);
o3d.build();
}
return o3d;
}
}
}
Could you tell me that what is my mistake?
Or is there simple load3ds example for android?
Thank you.
