I'm getting white (blank) textures on everything when running on the
Droid and Galaxy S devices.
My textures are all power-of-two PNGs and they're in the /res/drawable-
nodpi folder.
Here's my code:
public GLTextures(GL10 gl, Context context) {
if(gl==null)return;
this.gl = gl;
this.context = context;
this.textureMap = new java.util.HashMap<Integer, Integer>();
sBitmapOptions.inPreferredConfig = Bitmap.Config.RGB_565;
}
public void freeTexs(){
gl.glDeleteTextures(textures.length, textures,0);
textureFiles = null;
}
public void loadTextures() {
if(gl==null)return;
int[] tmp_tex = new int[textureFiles.length];
gl.glGenTextures(textureFiles.length, tmp_tex, 0);
textures = tmp_tex;
for (int i = 0; i < textureFiles.length; i++) {
this.textureMap.put(new Integer(textureFiles[i]), new
Integer(i));
int tex = tmp_tex[i];
gl.glBindTexture(GL10.GL_TEXTURE_2D, tex);
gl.glTexParameterf(GL10.GL_TEXTURE_2D,
GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR);
gl.glTexParameterf(GL10.GL_TEXTURE_2D,
GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR_MIPMAP_NEAREST);
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);
gl.glTexEnvf(GL10.GL_TEXTURE_ENV,
GL10.GL_TEXTURE_ENV_MODE, GL10.GL_MODULATE);
InputStream is =
context.getResources().openRawResource(textureFiles[i]);
Bitmap bitmap;
try {
bitmap = BitmapFactory.decodeStream(is, null,
sBitmapOptions);
} finally {
try {
is.close();
} catch (IOException e) {
// Ignore.
}
}
buildMipmap(gl, bitmap, tex);
bitmap.recycle();
}
}
private void buildMipmap(GL10 gl, Bitmap bmp, int tex) {
//
int level = 0;
//
int height = bmp.getHeight();
int width = bmp.getWidth();
while (height >= 1 || width >= 1) {
GLUtils.texImage2D(GL10.GL_TEXTURE_2D, level, bmp, 0);
if (height == 1 || width == 1) {
break;
}
// Increase the mipmap level
level++;
//
height /= 2;
width /= 2;
Bitmap bitmap2 = Bitmap.createScaledBitmap(bmp, width,
height,
true);
// Clean up
bmp.recycle();
bmp = bitmap2;
}
}
Here's my setup code in my renderer's onSurfaceCreated method:
// Define the lighting
float lightAmbient[] = new float[] { 1f, 1f, 1f, 1 };
float lightDiffuse[] = new float[] { 1, 1, 1, 1 };
float[] lightPos = new float[] { 0, 0, 0, 1};
gl.glEnable(GL10.GL_LIGHTING);
gl.glEnable(GL10.GL_LIGHT0);
gl.glLightfv(GL10.GL_LIGHT0, GL10.GL_AMBIENT, lightAmbient, 0);
gl.glLightfv(GL10.GL_LIGHT0, GL10.GL_DIFFUSE, lightDiffuse, 0);
gl.glLightf(GL10.GL_LIGHT0, GL10.GL_CONSTANT_ATTENUATION, 1.0f);
gl.glLightf(GL10.GL_LIGHT0, GL10.GL_LINEAR_ATTENUATION, 0.01f);
gl.glLightf(GL10.GL_LIGHT0, GL10.GL_QUADRATIC_ATTENUATION, .1f);
gl.glLightfv(GL10.GL_LIGHT0, GL10.GL_POSITION, lightPos, 0);
// Define the materials
float matAmbient[] = new float[] {1, 1, 1, 1 };
float matDiffuse[] = new float[] {1, 1, 1, 1 };
gl.glMaterialfv(GL10.GL_FRONT_AND_BACK, GL10.GL_AMBIENT,
matAmbient,
0);
gl.glMaterialfv(GL10.GL_FRONT_AND_BACK, GL10.GL_DIFFUSE,
matDiffuse,
0);
gl.glDisable(GL10.GL_DEPTH_TEST);
gl.glEnable(GL10.GL_BLEND);
gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE);
gl.glDepthFunc(GL10.GL_LEQUAL);
gl.glEnableClientState(GL10.GL_VERTEX_ARRAY);
gl.glDisable(GL10.GL_DITHER);
//Enable textures
gl.glHint(GL10.GL_PERSPECTIVE_CORRECTION_HINT,GL10.GL_NICEST);
gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY);
gl.glEnable(GL10.GL_TEXTURE_2D);
Any help is appreciated.
