"-cam.backBx, -cam.backBy, -cam.backBz",how to get them?

please post me that part (6 lines or so...), may be that can help me

The projection matrix is implicitly created by the engine based on the current fov settings and the far and near clipping plane. There's no way to set it directly from the outside. The model view matrix in OpenGL is a combination of object space->world space and world space->camera space transformations. The matrix itself is set by the engine based on an object's transformation and the camera rotation and position. You can't take some random GL code and just extract the matrices to feed them into jPCT-AE. You have to understand what the code does and rebuild it's behaviour by using the means that the engine offers.

how can I understand what the code does,can you give me some open source code about that?

thank you very much, it seems can't release all texture memory from my system,can you tell me how to clear all memory completely,
use as following code:

TextureManager.getInstance().removeTexture(texturesName);
TextureManager.getInstance().flush();
TextureManager.getInstance().removeAndUnload(textureName,frameBuffer)

right?

you 2 lines code mean the global variable Object3D model is not the same as local variable Object3D model.
I have done that in onDestory(),the code as following:

                @Override
protected void onDestroy() {
                model=null;
                fb=null;
                world=null;
                TextureManager.getInstance().removeTexture(texturesName);
                 Loader.clearCache();               
               }

above is right?

I have two activities.one is first page,it has a start button,when I clike this button,it will load my two md2 models at the same time ,when they load completely,it will skip two my game activity,in my game activity , this time,two models work normally, when I click key Back,it will go back to my first page,but at this time,if I click the start button again,my app will crashed,and there will be some error messages in logcat:

this is out of memorry,I just want to know how to clear entire cache after load md2 models before go back to first page?

yeh,that is file size,oh my mistake,each model about 600kB,and each texture picture about 100kB ,I have use a thread to load them at the same time. but when I load about the third one, my app is crashed,the log error is out of memory.my code as following:

for(int i=0;i<5;i++){
modelList.add(Loader.loadMD2(this.getResources().getAssets().open(modelName[i], AssetManager.ACCESS_UNKNOWN), 3f));
TextureManager.getInstance().addTexture(texturesName[i], 
new Texture(BitmapFactory.decodeResource(this.getResources(), texturePictureId[i])));
}


I know there must be a good way to deal with this situation like my question.can you help me how to do that?   

Hello,I have 5 md2 models,each model is about 2M,I want to load them at the same time,I don't know how to load it correctly, maybe there will be out of memorry? I have no idea,please give me a hint.

I have load md2 successully,but every time I use code finish my Activity,after that I restart my app,it often crashed. the log is as following:

I'm sure some memory is not released when I exist this activity, how to release it use jpct-ae ?

oh,thank you ,I have figure it out. when I draw camera texture,I have disable some key code:
gl.glDisable(GL10.GL_TEXTURE_2D);
gl.glEnable(GL10.GL_DEPTH_TEST);
gl.glDisableClientState(GL10.GL_VERTEX_ARRAY);
gl.glDisableClientState(GL10.GL_TEXTURE_COORD_ARRAY);

so,if use above codes before I draw other texure,it will never show texture on other models.

I found that,if I draw camera Texture without using jpct-ae,and then draw md2 model texture using jpct-ae,it can't show the model texture. if I comment the code about drawing camera Texture, and then draw md2 model texture,it can show the texture.it's so strange!!!
maybe camera Texture effects the model texture.
question: jpct-ae's texture whether can be effected by any other thing or not? how to solve it? please



onDrawFrame(GL10 gl) {

matrixTrans=new Matrix();
matrixTrans.translate(a,b,c)
model.setTranslationMatrix(matrixTrans);

//doAnim(); 
world.renderScene(fb);
world.draw(fb);
fb.display();
}
   
a,b,c is my dynamic value,it can control my model moved by my marker correctly before using jpct-ae. But with jpct, it seems can't be transformed correctly,at least not entirely correct. eg.when my marker is away from my device camera,it can be scaled correctly.but when I move my marker from up to down or from left to right,it can not moved to right place,but the  orientation is right.I don't know it is effected by wold or camra of jpct-ae. please?

Thank you very much

the logcat is the issue of no texture:
