Alternative modeling and design tools are Oracle JDeveloper and Oracle SQL Developer Data Modeler. It is a constraint-based parametric modeler with simple mechanical simulation capabilities. Rhinoceros is primarily a free form surface modeler that utilizes the NURBS mathematical model. Scicos is a graphical dynamical system modeler and simulator. Particularly, the smaller scope eliminated the need for any type of character modeler or animator. Archimatix is a node-based parametric modeler extension for Unity 3D. SMI is a stochastic programming modeler and solver written in C++. OpenSCAD, another open-source parametric 3D modeler, also uses AppImage as a Linux binary download option. FreeCAD, an open-source parametric 3D modeler, uses AppImage as the primary Linux binary download. Hexagon is a subdivision-type 3D modeler owned by DAZ 3D. One such example is the Pod guitar amplifier modeler. The Games edition includes the Modeler, Compiler, and SDK. In April 1992, Stratasys sold its first product, the 3D Modeler. The tool was later renamed to CA ERwin Data Modeler. Harold "Howie" Weed was computer graphics modeler for the film.
