Mobius: Constraints Theory

Generative Modelling, Part 3: Constraints Theory
Constraints specify conditions that need to be satisfied.
Two categories of constraints:
* Dimensional constraints: focus on spatial dimensions. They include things like distances,
angles, and areas.
* Geometric constraints: focus on relationships between entities. They include things like
collinearity, perpendicularity, and parallelity.
The three approaches for solving constraints are:
* Analytical - uses mathematics to satisfy simple constraints.
* Procedural - defines a sequence of steps that lead to a solution that satisfies the constraint.
* Numerical - uses a solver to search for solutions to more complex constraints.
Constrains can have parameters.
* For example, there may be a height-limit constraint. The limit can be specified as a script
parameter.
