Hmm, sounds as if Mark's getting to grips with shaders now. Does that mean the basic 3d module is complete?
What do you mean by "the basic 3D module"?Mark is not getting to grips with shaders. He is getting to grips with presenting the complex and not very accessible world of shaders in an abstract model that normal people can understand.
Writing the engine is the easy part, presenting it in an intuitive, conciece and accessable fashion is the hard bit.
I think the demos he's released so far, pretty much illustrate that the rendering side (if that's what you mean by basic) is pretty much nailed.
And by the way Toby, no it isn't funny anymore (if it ever was). You should add another code entry ASAP. :o>
