sorry , I have another question , when i set
gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR);
gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR);
the texture shows ok , but when I set
gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER,GL10.GL_LINEAR_MIPMAP_LINEAR);
gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER,GL10.GL_LINEAR);
gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL11.GL_GENERATE_MIPMAP, GL10.GL_TRUE);
the texture become white , How can i do mipmap ? thank you !
