For viewing in OpenGL, you will need to create a surface material with that image on it.
Make the image large enough so you don't notice the repeating pattern.
For rendered images (Cinerender) you will need to create the same surface there using the same image.
I know it is possible to create random coloured tiles (bricks) in Cinerender without using an image - but I have only seen that done with rectangular pattern - not triangular.
If you want more control over the pattern of the tiles themselves you would have to create a GDL object (you will need to know how to script GDL), or you could use the curtain wall tool to create a pattern like this.
I think you best bet is a large enough sample image that you add to a surface.
