I work on a program using OpenGL ES3.0 and I would like to do bit-wise shift on texture data. I can't render anything when I specify my texture as GL_RGB8UI and GL_RGB_INTEGER. But for GL_RGB8 and GL_RGB it works, I render an image but I can't perform a bit-wise shifting because it is not integer's data.
So I am asking if integer texture is supported on this gpu. I saw that an extension exists for this but it is not listed in the imx6 Graphics User Guide.
Thanks for your help.
