What do expressions look like?

This is a scratch pad for the types of expressions we want to support.

Reduction expressions (triggers and filter parameters)

An expression that reduces to a single variable. Example types:

• bool (integer)
• integer
• double
• vec3

Example syntax:

• bool: max("pressure") > 10.0
• integer: 1 + 1
• double: pow(1.0,0.5), magnitude(vec3(1.0, 2.0, 3.0) - coordinate(max("pressure")))
• vec3: coordinate(max("pressure"))

Variable expressions (computing a new field on the mesh)
