Hi, 

your OpenGL code is incorrect;

the main problem is this:

        glDrawArrays(GL_TRIANGLES, 0, foxboxOBJNumVerts);

Awesome . . . . 
Thank You AlessandroB
 

its SDK 2.0??
hei how to add different object in different image target....could you explain step by step??

thx

Gan . . just use my code below n paste to image target sample n dont forget to remove all the glNormal in your object . . .
tell me if there is anythng that goes wrong ...

Yeah thx gan..solved :D

When using my own data set...my model look collision
Image:attach file

The models should appearjust on top of the targets... maybe you are rendering two different models for the same target;

my suggestion is to double-check your OpenGL code in the renderFrame() method of your CPP code, there is probably something wrong there..

-----EDIT-----
Ah...its all about marker

Hi,

I've following all the code

But i still got this :

Any one help me pls.
Thank you

Hi Perucha,

it looks like there is so;ething wrong in your OpenGL code that causes that crash;

for example, you might have some issues with the size of your vertex arrays, or any other data/rendering mismatch;

but you really need to debug / check your code, we cannot help with OpenGL custom rendering issues

Hi,

Here is my problem, .java code :

    /** We want to load specific textures from the APK, which we will later
    use for rendering. */
    private void loadTextures()
    {
        mTextures.add(Texture.loadTextureFromApk("TextureBajuPertama.png",
                getAssets()));
        mTextures.add(Texture.loadTextureFromApk("TextureBajuBlue.png",
                getAssets()));
        mTextures.add(Texture.loadTextureFromApk("TextureBajuBrass.png",
                getAssets()));
        mTextures.add(Texture.loadTextureFromApk("TextureBajuRed.png",
                getAssets()));
        //mTextures.add(Texture.loadTextureFromApk("TextureBajuKedua.png",
                //getAssets()));
    }

When i use that code, i can running my project, but the second object showed without texture

So i Uncomment the TextureBajuKedua, but it becomes an error, "fatal error"

Here code in .cpp :

// Did we find any trackables this frame?
    for(int tIdx = 0; tIdx < state.getNumTrackableResults(); tIdx++)
    {
        // Get the trackable:
        const QCAR::TrackableResult* result = state.getTrackableResult(tIdx);
        const QCAR::Trackable& trackable = result->getTrackable();
        QCAR::Matrix44F modelViewMatrix =
            QCAR::Tool::convertPose2GLMatrix(result->getPose());        

        // Choose the texture based on the target name:
        int textureIndex;
        if (strcmp(trackable.getName(), "chips") == 0)
        {
            textureIndex = 0;
            glVertexAttribPointer(vertexHandle,3, GL_FLOAT, GL_FALSE, 0, bajuPertamaVerts);
            glVertexAttribPointer(textureCoordHandle, 2, GL_FLOAT, GL_FALSE, 0, bajuPertamaTexCoords);
        }
        else if (strcmp(trackable.getName(), "stones") == 0)
        {
            textureIndex = 1;
            glVertexAttribPointer(vertexHandle,3, GL_FLOAT, GL_FALSE, 0, bajuKeduaVerts);
            glVertexAttribPointer(textureCoordHandle, 2, GL_FLOAT, GL_FALSE, 0, bajuKeduaTexCoords);
        }
        else
        {
            textureIndex =2;
        }

Thanks  you

In your code you seem to miss this line:

 glDrawArrays(GL_TRIANGLES, 0, Your_Mesh_NumVerts);

Hi,

I do, here :

But still error

Thank you

OK. So, from the code below, everything seems to be correct on the OpenGL level, or at least I cannot see anyting obviously wrong.

So, my guess is that there could be something wrong with the definitions of those vertex arrays (check their header files .h), or perhaps the arrays are toolarge (for instance, if the number of vertices exceeds 64K you might have problems on some devices).

Have you tried the same code using a different set of meshes ?

Hi,

Each object only have around 10k number of vertices

Which makes me confuse is why when i replace the texture, its becames erros

I've following all the code below

Please take a look from my full code, i think i missing something that i can't find it

Thank you very much

Sorry, but I cannot debug your entire application code for you; at a first glance the code looks correct, but given that, as you said, the probem arises when you change the textures to use your own images, you may want to check the following things:

- check the value of textureCount, and ensure that it is actually 3 or more (as you load many textures in the Java code); this is important because otherwise the textureIndex in your C++ code might exceed the texturecount

- check that all textures in C++ are created sccessfully, without any error logged by the application

- check the size of your textures; it could be that the code is correct, but the images are too large, thus causing the crash

- check that the textures dimensions are power-of-two (e.g. 256 x 256 or 256 x 128, or 512 x 256, etc...), as your device OpenGL driver might not like non-power-of-two textures

Hi,

I've found the error, thank you so much AlessandroB

It's about the dimensions of my texture ..

But i've question, i've try to resize my object like this : (left scale 100.0f and right scale 200.0f)
