    Monster Mash

    Monster Mash

    New Sketch-Based Modeling and Animation Tool

    Monster Mash is a playful, research-grade 2D-to-3D modeling and animation tool that turns quick pen strokes into lively, deformable characters in seconds. You sketch a silhouette and interior strokes to hint at limbs or structure, then “inflate” the drawing into a volumetric, puppet-like mesh that preserves the feel of the original art. The interface favors immediacy: draw, inflate, pose, and record motion directly in the canvas, without manual rigging, weight painting, or complicated asset pipelines. Under the hood it builds a lightweight surface and auto-assigns handles so you can grab and move parts intuitively, with smooth deformations propagating across the body. ...

    ...We don't need to write D3 code any more. C3 gives some classes to each element when generating, so you can define a custom style by the class and it's possible to extend the structure directly by D3. C3 provides a variety of APIs and callbacks to access the state of the chart. By using them, you can update the chart even after it's rendered. C3 enables deeper integration of charts into your application. Because of the dependence on D3, C3 supports only modern browsers D3 supports. For IE9 and IE10, polyfill is required because c3 uses MutationObserver, which is not supported in those versions. ...
