Текстуры Android «white box» OpenGL ES 1.0 на некоторых устройствах

Question

У меня есть следующая проблема. Я пишу какое-нибудь приложение для Android, которое использует opengl es 1.0 Я использую GLSurfaceView и пользовательский Renderer. Вот методы моего пользовательского визуализатора onDrawFrame, onSurfaceChanged, onSurfaceChanged:

@Override 
public void onDrawFrame(GL10 gl) { 

    gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); 
    gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY); 

    // clear Screen and Depth Buffer 
    gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT); 

    // Reset the Modelview Matrix 
    gl.glLoadIdentity(); 

    // Drawing 
    gl.glTranslatef(0f, 0f, -3.0f);  // move 5 units INTO the screen 
              // is the same as moving the camera 5 units away 
    //  gl.glScalef(0.5f, 0.5f, 0.5f);   // scale the square to 50% 
              // otherwise it will be too large 
    square.draw(gl, mScrollable.getIndexA(), mScrollable.getIndexB(), mScrollable.getAlphaValue());   // Draw the triangle 
} 

@Override 
public void onSurfaceChanged(GL10 gl, int width, int height) { 
    if(height == 0) {      //Prevent A Divide By Zero By 
     height = 1;       //Making Height Equal One 
    } 

    gl.glViewport(0, 0, mWidth, mHeight); //Reset The Current Viewport 
    gl.glMatrixMode(GL10.GL_PROJECTION); //Select The Projection Matrix 
    gl.glLoadIdentity();     //Reset The Projection Matrix 

    //Calculate The Aspect Ratio Of The Window 
    GLU.gluPerspective(gl, 45.0f, (float) width/(float) height, 0.1f, 100.0f); 

    gl.glMatrixMode(GL10.GL_MODELVIEW);  //Select The Modelview Matrix 
    gl.glLoadIdentity();     //Reset The Modelview Matrix 
} 


@Override 
public void onSurfaceCreated(GL10 gl, EGLConfig config) { 
    // Load the texture for the square 
    square.loadGLTexture(gl, this.context); 

    gl.glEnable(GL10.GL_BLEND); 
    gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA); 
    gl.glEnable(GL10.GL_TEXTURE_2D);   //Enable Texture Mapping (NEW) 
    gl.glShadeModel(GL10.GL_SMOOTH);   //Enable Smooth Shading 
    gl.glClearColor(0.0f, 0.0f, 0.0f, 0.5f); //Black Background 
    gl.glClearDepthf(1.0f);      //Depth Buffer Setup 
    gl.glEnable(GL10.GL_DEPTH_TEST);   //Enables Depth Testing 
    gl.glDepthFunc(GL10.GL_LEQUAL);    //The Type Of Depth Testing To Do 

    //Really Nice Perspective Calculations 
    gl.glHint(GL10.GL_PERSPECTIVE_CORRECTION_HINT, GL10.GL_NICEST); 

} 

И мой площади класс для визуализации текстур:

private int[] textures; 
private GL10 mGl; 
private FloatBuffer vertexBuffer; // buffer holding the vertices 
private float vertices[] = { 
     -1.0f, -1.8f, 0.0f,  // V1 - bottom left 
     -1.0f, 1.3f, 0.0f,  // V2 - top left 
     1.0f, -1.8f, 0.0f,  // V3 - bottom right 
     1.0f, 1.3f, 0.0f   // V4 - top right 
}; 

private FloatBuffer textureBuffer; // buffer holding the texture coordinates 
private float texture[] = {   
     // Mapping coordinates for the vertices 
     0.0f, 1.0f,  // top left  (V2) 
     0.0f, 0.0f,  // bottom left (V1) 
     1.0f, 1.0f,  // top right (V4) 
     1.0f, 0.0f  // bottom right (V3) 
}; 
private GlAnimationCache cacheHelper; 

public void loadGLTexture(GL10 gl, Context context) { 
    // loading texture 
    mGl = gl; 
    gl.glGenTextures(mImageEntityList.size(), textures, 0); 

    cacheHelper = new GlAnimationCache(mContext, mImageEntityList, mGlRenderer, mGlSurfaceView); 
    cacheHelper.initCache(); //it init cache in background thread 
} 

public void removeTextureAt(int position){ 
    mGl.glDeleteTextures(1, textures, position); 
} 

public void bindTextureAt(final Bitmap bitmap, int position){ 

    // generate one texture poi, 0); 
    // ...and bind it to our array 
    mGl.glBindTexture(GL10.GL_TEXTURE_2D, textures[position]); 


    mGl.glVertexPointer(2, GL10.GL_FLOAT, 0, vertexBuffer); 
    mGl.glTexCoordPointer(2, GL10.GL_FLOAT, 0, textureBuffer); 

    // create nearest filtered texture 
    mGl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_NEAREST); 
    mGl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); 

    //Different possible texture parameters, e.g. GL10.GL_CLAMP_TO_EDGE 
    //  gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_REPEAT); 
    //  gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_REPEAT); 

    // Use Android GLUtils to specify a two-dimensional texture image from our bitmap 
    GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, GLUtils.getInternalFormat(bitmap), bitmap, GLUtils.getType(bitmap), 0); 
    bitmap.recycle(); 
} 

private int prevIndex = 0; 

/** The draw method for the square with the GL context */ 
public void draw(GL10 gl, int indexA, int indexB, float alpha) { 
    // bind the previously generated texture 

    if(prevIndex != indexA){ 
     cacheHelper.synchronizeCache(indexA); 
     prevIndex = indexA; 
    } 
    // Point to our buffers 
    gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); 
    gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY); 

    gl.glBindTexture(GL10.GL_TEXTURE_2D, textures[indexA]); 

    // Set the face rotation 
    gl.glFrontFace(GL10.GL_CW); 

    // Point to our vertex buffer 
    gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertexBuffer); 
    gl.glTexCoordPointer(2, GL10.GL_FLOAT, 0, textureBuffer); 

    gl.glColor4f(1, 1, 1, 1f); 

    // Draw the vertices as triangle strip 
    gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, 0, vertices.length/3); 

    //Disable the client state before leaving 
    gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); 
    gl.glDisableClientState(GL10.GL_TEXTURE_COORD_ARRAY); 



    gl.glBindTexture(GL10.GL_TEXTURE_2D, textures[indexB]); 

    // Set the face rotation 
    gl.glFrontFace(GL10.GL_CW); 

    // Point to our vertex buffer 
    gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertexBuffer); 
    gl.glTexCoordPointer(2, GL10.GL_FLOAT, 0, textureBuffer); 

    gl.glColor4f(1, 1, 1, Math.abs(alpha)); 

    // Draw the vertices as triangle strip 
    gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, 0, vertices.length/3); 

    //Disable the client state before leaving 
    gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); 
    gl.glDisableClientState(GL10.GL_TEXTURE_COORD_ARRAY); 
} 

Таким образом, проблема заключается в следующем: На Samsung S5, Текстуры Alcatel One Touch 4033D и Motorolla Droid Razr отлично выглядят. Но на Samsung Galaxy Nexus я вижу только «белую коробку».

Я попытался изменить размер текстуры на мощность 2 (512 x 512), но это не поможет.

Answer 1

В Square класса надстройкой функции:

public boolean isNPOTSupported(GL10 gl) { 
     String extensions = gl.glGetString(GL10.GL_EXTENSIONS); 
     return extensions.indexOf("GL_OES_texture_npot") != -1; 
    } 

И когда вы Генерировать текстуры, добавьте это:

 final boolean isNPOTSupported = isNPOTSupported(gl); 
     if(isNPOTSupported) { 
      gl.glGenTextures(mImageEntityList.size(), textures, 0); 
     }else{ 
      for(int i = 0; i < mImageEntityList.size(); i++){ 
       gl.glGenTextures(1, textures, i); 
      } 
     } 

Вместо этого:

gl.glGenTextures(mImageEntityList.size(), textures, 0);
