MD (Mesh Deformation) is a collection of mesh manipulation tools for the Unity Engine, suitable for both beginners and advanced users. The package includes a simple & primitive vertex editor (PC, VR, Mobile), a collection of various well-known modifiers, physically-based procedural tools, spline-based tool for object instancing, geometry primitives, and more. The MD package comes with numerous examples, detailed explanations, source code and real-time support on Discord with unlimited updates.

The development of this package began in 2013 by me, Matej Vanco. It all started with basic features such as generating generic points for meshes and basic controls for Skinned Mesh bones. The package was officially published on November 12, 2015. At that time, ‘mesh deformation’ was not very common in Unity and this package was one of the very first assets focused on mesh manipulation in Unity Engine.

It’s a comprehensive collection of mesh deformation techniques in Unity, based on well-known modifiers and mesh features that have been tested in many commercial projects by numerous users over the years.

This documentation focuses on the Application Programming Interface (APi) to introduce the entire library to a programmer.
Please read the APi documentation carefully, as some implementations and setups require special attention.
