News

06/23/2017 Bombshell 1.1.970 has been released. It fixes behavior of Objects of zero size, TextureView, TextureManager, Toon Shader color setters, custom shaders and more... It also adds preprocessor directive support for shader plugins, configurable skybox geometry, and extends our Unit Text Framework.

11/16/2016 Bombshell 1.1.777 has been released. It fixes a small number of bugs and adds a Scan Line post processing effect (thanks @contriteobserver).

9/7/2016 The official release of Bombshell 1.1.610 is out. We will continue to support this release moving forward how ever bug fixes will be minimal. The decision was made that the design of the core engine was inhibiting correcting some of the larger issues. To this end, we have begun development of a 2.0 version - see issue 1755 for details. Development is happening in the v2.0-development branch here

8/29/2016 An initial effort for adding unit testing to Rajawali has been made. This initial focus has been on the core math classes and will ideally expand as bug fixes progress. Pull requests for unit tests are welcome and any "bug fix" PRs which include unit tests or issues which include unit tests to demonstrate a failure will be given the highest priority.

General

Rajawali is a 3D engine for Android based on OpenGL ES 2.0/3.0. It can be used for normal apps as well as live wallpapers.

Made With Rajawali

Numerous apps and live wallpapers have been made with Rajawali. Check them out!

Using Rajawali with mavenCentral()

Using Rajawali is as simple as adding a single line to your gradle dependencies:

implementation 'org.rajawali3d:rajawali:x.x.x@aar where x.x.x is the version number (and the last number is the build number). If you wish to use the master branch snapshot, append -SNAPSHOT. For example, to use release 1.0.325, you would use:

implementation 'org.rajawali3d:rajawali:1.0.325@aar

To use the master branch build 48 snapshot 1.0.48-SNAPSHOT, you would use:

implementation 'org.rajawali3d:rajawali:1.0.48-SNAPSHOT@aar

All commits to master and development branch are deployed as snapshots. All tags will be deployed as releases. To see the latest build number, see the build history and be sure you choose a master branch build.

For the above to work you will need to make sure your repository list includes:

mavenCentral() for releases, and maven { url "https://oss.sonatype.org/content/repositories/snapshots/" } for snapshots.

Alternatively, if you checkout Rajawali via GIT, you can run gradle assembleRelease uploadArchives (or simply add a Gralde launch config to Android Studio for the assembleRelease and uploadArchives tasks). This will deploy to your local maven repository. Consuming apps should have mavenLocal() in their repository list and add implementation 'org.rajawali3d:rajawali:1.0.0-SNAPSHOT@aar to their dependencies.

Using Rajawali with Jitpack

Just add the following lines to your build.gradle Here you see more details https://jitpack.io/#rajawali/rajawali

dependencies {
    implementation "com.github.rajawali:rajawali:$latest_version"
}

To tell Gradle where to find the library, make sure build.gradle also contains this:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

rajawaliexamples's Issues

The RajawaliRipplesActivity is not work

First i download Rajawali and RajawaliExamples code;
Second import two project to eclipse;
Third run RajawaliExamples project in eclipse;
When i enter"Touch Ripples Effect", Touch the screen,there is no Ripples Effect.But when I install RajawaliExamples.apk from download,It is work OK.

onDrawFrame

Hai, i need to add object 3d and texture in runtime. I see a lot of solution in rajawali github's issue, they update texture runtime in onDrawFrame. But i can find override onDrawFrame, how to create object 3d and texture runtime?

Remove Override annotation error

When I run the examples, I get multiple errors mostly saying "Remove @ Override annotation".

For example, getCount in ExamplesAdapter,.java, onAnimationStart in RajawaliExampleActivity, etc.

So the question is how to run the examples. I have not added the libfix-GLES20.so into the project. How to link this.

md5 mesh issue

i am using maya 2014 for rigging and animation, then i export backed animation as FBX format from maya 2014, after that i a m importing this fbx in blender 2.78 after that i am using add on script by name '' io_export_md5-263 '' http://www.katsbits.com/tools/#md5 for exporting md5 mesh and animation,
untill unless i am not using light everything is fair animation working properly, but as i use light mesh getting black spoted, use of light is compulsory for me because i have to use normal map along with diffuse map.(we check md5mesh and md5animation in this viewer http://away3d.com/awaybuilder/ and we see black spots on model)

can any one help me with this issue ?

i want to use this .md5animation and .md5mesh in android studio/eclipse with rajawali framework.

thanks in advance.

Camera rotation around object

I have tried the following methods for rotating the camera around a given point or object. The only method that actually changed anything was using the ChaseCamera, but I want to be able to deliberately rotate around an object or point.

mCamera.setLookAt(0, .5f, 0);
float[] matArray = new float[16];
Matrix4 cameraMat = new Matrix4((float)Math.cos(Math.toRadians(90d)), 0, (float)Math.sin(Math.toRadians(90d)), 0, 0, 1, 0, 0, -(float)Math.sin(Math.toRadians(90d)), 0, (float)Math.cos(Math.toRadians(90d)), 0, 0, 0, 0, 1);
cameraMat.toFloatArray(matArray);
mCamera.setRotationMatrix(matArray);

mCamera.setLookAt(0, .5f, 0);
mCamera.setRotY(90f);

mCamera = new ChaseCamera(new Number3D(0, .5f, 2), .1f);
((ChaseCamera)mCamera).setObjectToChase(object5);

If I create my own camera object with

mCamera = new Camera();

and assign it to the superclass's (RajawaliRenderer) mCamera property, nothing at all is displayed. How can I set the origin of the camera and rotate around it? Is this a bug or am I doing something incredibly wrong here?

problem when I try to import textures from model obj

Hi,

I'm trying to make an aplication that loads an 3d object.

when i load this object (http://rgcouto.net/alexandre/COKE/fineObj/), all works fine.
screenshot: http://rgcouto.net/alexandre/COKE/Screenshot_2013-01-10-15-04-42.png

But when i try load my object (http://rgcouto.net/alexandre/COKE/myObj/), exported from blender, the texture doesn't appear and the object is dark..
screenshot: http://rgcouto.net/alexandre/COKE/Screenshot_2013-01-10-15-02-27.png

What did I do wrong?
What i have to do, to make my object appear with texture?

My Blend file: http://rgcouto.net/alexandre/COKE/blend/
My renderer: http://rgcouto.net/alexandre/COKE/ObjRenderer.java

ArrayIndexOutOfBoundsException for large models

I get an exception when trying to import a very large model with your library. It works fine if I split the model up into smaller portions ("export selection" in blender), but if I try to import the complete model I get an the following exception:

java.lang.ArrayIndexOutOfBoundsException: index=-24919 length=88258

with the following stack trace:

Navigation Drawer broken on Amazon FireTV

The navigation drawer loses focus after first fragment selection making it impossible to browse the entire application without lots of un-fun force closes.

svgpath grammar question?

path id="batman-path22" center="22.395,127.223" height="4" style="fill:rgb(0,0,0)" d="M22.395-127.223c-4.492,11.344-4.688,33.75,0,44.883c-11.328-4.492-33.656-4.579-44.789,0.109c4.491-11.354,4.688-33.75,0-44.892C-11.066-122.63,11.262-122.536,22.395-127.223Z"

This path is right. But I don't understand its grammar.
(I point it out I have much experience in svg) .I can understandpath = "M550.1 163.4 L576.5 170.5 L579.4 174.8 L606 169.6 L641.3 181.3 L669 220.2 L593.7 236.1 L584.9 222.6 L595.2 220.5 L586.2 206.7 L539.8 216.1 L524.8 239.1 L471.9 250.1 L461.4 231.3 L471.1 229.4 L464.8 218.1 L455.1 220.1 L435.6 185.1 Z";

Now back to question." M22.395-127.223c-4.492,11.344-4.688,33.75,0,44.883c......."
Herer “- ” stands for space character ? But I replace all and at last I find it is error.
So I Put it out and I want to know "M22.395-127.223c-4.492,11.344-4.688,33.75,0,44.883c"
M - c C what means?

Non touch devices are unable to see navigation selection.

When using the navigation drawer it is impossible to determine the current selection when navigating with a directional pad.

How to stretch one svg path ?

I can use sample way to make 2d svg picuture.
But I need 3d path.

final String path = "M22.395-127.223c-4.492,11.344-4.688,33.75,0,44.883"
+ "c-11.328-4.492-33.656-4.579-44.789,0.109c4.491-11.354,4.688-33.75,0-44.892"
+ "C-11.066-122.63,11.262-122.536,22.395-127.223z";

My requirement is to add one height value(z=50) in all svg path points.
Thus (22.395,127.223) ==========> (22.395,127.223,50).
Other points are likes above.

But I find it doesn't work in SVGPathFragment.java.
1 for (int j = 0; j <= subdiv; j++) {
Vector3 point = new Vector3();
subPath.calculatePoint(point, (float) j / (float) subdiv);
point.z=50; // I add it
points.add(point);
}
2 I don't know how to stretch it to polygon whose height is 100. (please stretch it)

3d model load

can I use this lib to load 3d model objects to my Android project
the problem I have is I want to load a car object this car object has some car components like a seat, mirror,engine, etc

-need to access these objects and change their color or change visibility

1- so what is a 3d object extension to use and where can I find a sample like this
2- can I use this lib for that

Errors

public void onSurfaceCreated(GL10 gl, EGLConfig config) {
((RajawaliExampleActivity) mContext).showLoader();
super.onSurfaceCreated(gl, config);
((RajawaliExampleActivity) mContext).hideLoader();
}
there is a error in line 2 and 4 how to remove it

        }

and got an error like this.
I want to pick and drag object smoothly, but it immediately jumps to the touched position.

How to correct it ?
Thank for any help!

Models shift on camera movment

Hi,
I realised that the models of the Example shift towards the direction the camera of the smartphone is moved. The bigger the models the more the effect is visible. What could be the cause for that?

SkyBox mirror problem

Hi,
i am using your framework for panorama photos.
getCurrentScene().setSkybox(R.drawable.posx3, R.drawable.negx3,
R.drawable.posy3, R.drawable.negy3, R.drawable.posz3,
R.drawable.negz3);

but it mirrors the images. i mean all the writings on the buildings (in photos) are reversed.

any help please?

Touch issues

Hi,
I have checked out latest branch around a week ago, but the Interactive examples (object Picking and Touch & Drag) do not seem to work at my end. I hit a breakpoint on the 'onTouch' but not on 'onObjectPicked' .
Any idea what could be wrong?
I have tried it on 3 different devices, same behavior.

Thanks,

how to get Terrain data in TerrainFragment java file

TerrainFragment is rather good in Terrain expression.
I am interested but I can't find the terrain data in program.
It seems it make use of bitmap and not use geocode data(lon ,lat ,height )
Can you help me to explain it?

Animation rewrite broke animation example

Looks like we broke the animation example. Whoops.

G+ Api broken for communities

Google broke the G+ API for listing activities such that it only works for pages and profiles now. Until this is resolved on their end the community stream fragment will not function properly as it receives and empty list as results.

If you would like to help resolve this, please star this issue to bring it to the attention of the Google Engineers.

Can anyone help to solve this issue

Setting the color of .obj file.

Hello,

I am new to the field of 3D modeling in android. I am trying to load an .obj file (in this case, it is a car) and try to rotate it 360 degrees. I have been successfully able to do that. Now, I am trying to change the color of the car using the code below to black color.

`public class ObjectRenderer extends RajawaliRenderer {

private DirectionalLight directionalLight;
private Object3D mObjectGroup;
private Animation3D mCameraAnim, mLightAnim;

public ObjectRenderer(Context context) {
    super(context);
}

@Override
protected void initScene() {
    getCurrentScene().setBackgroundColor(1.0f, 1.0f, 1.0f, 1.0f);
    getCurrentCamera().setZ(16);

    LoaderOBJ objParser = new LoaderOBJ(mContext.getResources(), mTextureManager, R.raw.bmw);
    try {
        objParser.parse();
        mObjectGroup = objParser.getParsedObject();
        mObjectGroup.setScale(0.04f);
        mObjectGroup.setPosition(0.0f, -1.5f, 5.0f);
        //mObjectGroup.setColor(Color.BLACK) // I have tried this as well

        Material simple = new Material();
        simple.setColor(Color.BLACK); //I am setting the color here to black
        mObjectGroup.setMaterial(simple);

        getCurrentScene().addChild(mObjectGroup);

        mCameraAnim = new RotateOnAxisAnimation(Vector3.Axis.Y, 360);
        mCameraAnim.setDurationMilliseconds(8000);
        mCameraAnim.setRepeatMode(Animation.RepeatMode.INFINITE);
        mCameraAnim.setTransformable3D(mObjectGroup);
    } catch (ParsingException e) {
        e.printStackTrace();
    }
    getCurrentScene().registerAnimation(mCameraAnim);
    mCameraAnim.play();
}

@Override
public void onOffsetsChanged(float xOffset, float yOffset, float xOffsetStep, float yOffsetStep, int xPixelOffset, int yPixelOffset) {
}

@Override
public void onTouchEvent(MotionEvent event) {
}

}`

The issue is I cannot see the color change on the object. This is what I see no matter what color I add.

Can please someone tell me if I am missing something.

Currently selected fragment title lost on rotation

The action bar title of the currently selected example is lost on screen rotation defaulting the title back to "Rajawali Examples".

Fragments can not be replaced

The current abstract implementation for the fragments prevents them from being properly replaced due to retaining the surface view. The surface should be released in the onDestroyView and the fragment handling should be reworked to prevent a logical back button flow.

Cloning objects and replacing textures

I have a very simple object (4 point plane) loaded from a obj file which is cloned 6 times. It also has a texture defined in an mtl file.

The six instances of these objects I need to change their textures quickly and efficiently, but the problem I'm having is that adding and removing a texture on the object effects its material which is shared between all 6 objects. So the result is that when the texture is changed, all instances are changed.

There doesn't seem to be a way to clone a material probably due to performance issues. Could you suggest a way of doing this efficiently?

Switch to general-purpose materials

GouraudMaterial and PhongMaterial can now be used in place of some of the older, more specific materials. Switch to the more general-purpose materials where applicable.

Animation Framework Merge

@ToxicBakery Are we just waiting until we decide how to manage the three projects before merging the animation updates in or is it just that no one has done it?
