Wireframe VEX node

Implements a wireframe shader and outputs the final, lit color and opacity.

See also: Boxes, Bump Noise, Rings, Rounded Stars

This operator implements a wireframe shader and outputs the final, lit color and opacity.

It uses a Boxes operator to produce the basic wire pattern, then wipes out the filling. Since it is implemented as a subnetwork, this operator allows you to experiment easily with other pattern generators such as Rings and Rounded Stars, different lighting models, and so on.

At its simplest level, with the color and opacity piped into the Outputs operator, this operator is a good visualizer of the surface texture coordinates. However, it can easily evolve into a metal cage cage shader with reflectivity, rust, and dents.

If the Surface Normal (N) or texture coordinate inputs (s and t) are not connected, the global variables by the same names will be used instead. You will not touch “N” unless you want to apply additional displacement to the surface using an operator such as Bump Noise. If you need to access the global variables directly, they are available from the Global Variables operator.
