javascript - ways to simulate lighting in html canvas

Question

I have been coding a 3D viewer for the past few days, and for some reasons, I can't use webgl, I would like to know if there are ways to simulate surface shading in html5 canvas.

Basically, I'll be fetching face data from .obj files and constructing face by making polygons out of them, ie connecting four lines and filling them. I don't know if there are any interpolation functions that would let me treat each point like a vertex?
