These are a series of glass door/window/lighting panels modeled from the early products available in the International Art Glass Catalog of 1914. This catalog and it's designs are currently in the public domain.
These panels are modeled to the specifications given as options in the original catalog. eighth inch glass pieces welded together with quarter inch beading.
Polygon and Vertex count vary by panel though all are fairly low poly models that render very well. Each MAX file model includes the spline pattern each pane was designed from, flat and/or beveled glass pieces, corresponding welds and a suitable frame rendered in wood. Each panel is comprised of individually modeled pieces of glass.
The frames have been added to illustrate their architectural use and to ease their use as components in your 3D architectural scenes. These panels can also be used as templates for stained glass work, 3D printing, broken glass animations and much more.
