Tools for Conceptualizing Form
Okay, a quick post this week. These are a couple of diagrams I sketched out a little while ago that depict the spatial geometry I imagine before rendering form. I will refer back to these diagrams and elaborate on them when I get to various stages of preparing for my next painting. With these basic relationships I can hopefully establish consistent light effects between the many components of the scene and the light source. I can also plot geometrically where all the terminators and cast shadows are and use that as an interpretive tool when I get to modeling from life. These relationships also help in discerning between diffuse reflection and specular reflection. Conceptualizing these relationships, compared to mere value/shape copying, helps me avoid logically inconsistent patterns that emerge in a shifting live model.
