Monster Mash

Monster Mash is an experimental, browser-based sketch-to-3D modeling and animation tool that converts simple 2D drawings into animated 3D characters with minimal effort. Users begin by drawing a character or object directly in the sketching plane, then “inflate” the sketch into a volumetric 3D shape without traditional 3D modeling operations such as extruding, sculpting, or mesh editing. The tool automatically infers depth and volume from the outline, creating a lightweight 3D model that remains editable in the original 2D view.

Once a character is created, Monster Mash lets users define a simple skeleton and animate it through intuitive posing and motion controls, again entirely within the sketching plane. The system handles deformation and interpolation, enabling smooth, cartoon-like animations without requiring rigging expertise. Key capabilities include rapid prototyping of character ideas, quick iteration on shape and motion, and export options for use in other pipelines or presentations. Monster Mash is particularly useful for illustrators, educators, researchers, and designers who need to visualize character motion, create interactive demos, or generate concept animations, but who do not have the time or background to work with full-featured 3D modeling and animation software.
