Support / ELLIPSOID_ALIGNED vs ELLIPSOID_TRANSFORMED
« on: June 05, 2015, 09:37:50 am »
Can some explain what the difference between this options? Because the documentation is not clear how the ellipse will be transformed when performing collision detection with ELLIPSOID_TRANSFORMED options.

« on: May 22, 2015, 05:36:00 pm »
Hi all. I have some problem with displaying obj model.
Here code of my renderer class:
Code: [Select]
package com.amulet_it.openglexample;

import javax.microedition.khronos.egl.EGLConfig;
import javax.microedition.khronos.opengles.GL10;

import android.content.Context;
import android.graphics.Color;
import android.graphics.PointF;
import android.opengl.GLES20;
import android.opengl.GLSurfaceView;
import android.widget.Toast;

import com.threed.jpct.Camera;
import com.threed.jpct.FrameBuffer;
import com.threed.jpct.Interact2D;
import com.threed.jpct.Light;
import com.threed.jpct.Loader;
import com.threed.jpct.Matrix;
import com.threed.jpct.Object3D;
import com.threed.jpct.Primitives;
import com.threed.jpct.SimpleVector;
import com.threed.jpct.Texture;
import com.threed.jpct.TextureManager;
import com.threed.jpct.World;

import java.io.InputStream;
import java.util.HashMap;

public class MyRenderer implements GLSurfaceView.Renderer {

    private Context mContext = null;

    private FrameBuffer fb = null;
    private World world = null;
    private Camera cam = null;

    public MyRenderer(Context context) {
        mContext = context;
    }

    @Override
    public void onSurfaceCreated(GL10 unused, EGLConfig config) {

    }

    @Override
    public void onSurfaceChanged(GL10 unused, int width, int height) {

        if ( fb != null ) {
            fb.dispose();
        }

        fb = new FrameBuffer(width, height);

        world = new World();
        cam = world.getCamera();

        InputStream objStream = mContext.getResources().openRawResource(R.raw.test_obj);
        Object3D[] loadRes = Loader.loadOBJ(objStream, null, 3);

        Object3D cube = loadRes[0];
        cube.setCollisionMode(Object3D.COLLISION_CHECK_OTHERS | Object3D.COLLISION_CHECK_SELF);
        cube.build();

        world.addObject(cube);

        Light light = new Light(world);
        light.setPosition(new SimpleVector(0, -80, 0));
        light.setIntensity(140, 120, 120);
        light.setAttenuation(-1);

        world.setAmbientLight(20, 20, 20);

        cam.moveCamera(Camera.CAMERA_MOVEOUT, 200);
        cam.moveCamera(Camera.CAMERA_MOVEUP, 200);
        cam.lookAt(cube.getTransformedCenter());

    }

    @Override
    public void onDrawFrame(GL10 unused) {

        fb.clear(Color.RED);
        world.renderScene(fb);
        world.draw(fb);
        fb.display();

   }
}
Obj file in attachment as test.txt.
The main problem i'm don't see loaded object on the scene.
Can some help me please?
