Hi,

With OpenGL you can do asynchronous texture transfer using a PBO, as described here: http://www.opengl.org/registry/specs...fer_object.txt

Code :
glGenBuffers(1, &texBuffer);
glBindBuffer(GL_PIXEL_UNPACK_BUFFER_ARB, texBuffer);
glBufferData(GL_PIXEL_UNPACK_BUFFER_ARB, texSize, NULL, GL_STREAM_DRAW);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA8, texWidth, texHeight, 0, GL_BGRA, GL_UNSIGNED_BYTE, NULL);

However there is no such thing as "GL_PIXEL_UNPACK_BUFFER_ARB" on OpenGL ES. Is it possible to use PBO for texture transfer on OpenGL ES ? I can only find example with VBO.
