question: public void unbindTextures ( ) { int num = mTextureList . size ( ) ; if ( mPlugins != null ) for ( IMaterialPlugin plugin : mPlugins ) plugin . unbindTextures ( ) ; for ( int i = 0 ; i < num ; i ++ ) { ATexture texture = mTextureList . get ( i ) ; GLES20 . glBindTexture ( texture . getGLTextureType ( ) , 0 ) ; } GLES20 . glBindBuffer ( GLES20 . GL_ARRAY_BUFFER , 0 ) ; }
target:  Unbinds the texture from an OpenGL texturing target.
