Maya Reduce Poly Plugin


  


    A simple plugin for visualizing mesh reduction in Maya

    


    Full Demo

  



## About The Project

The algorithm is based on a paper from 1998: [A Simple, Fast, and Effective Polygon Reduction Algorithm](http://pds26.egloos.com/pds/201402/12/11/gdmag.pdf)

which collapses vertices with the lowest cost one by one. 

This gives a great visualization of the poly reduction process. 

The limits are that it takes a lot of time to process high poly mesh, and it only works for triangular meshes. 

A possible optimization is to compute to desire poly-count, store the vertex order and then re-construct the mesh all at once, 

but that would lose the slowly-reduced visualization.



  



## Getting Started

> The Plugin is compiled for Maya 2018

1. [Download](https://github.com/leixingyu/reduce-poly/releases/tag/v0.1.0) the latest plugin release

2. Load the `reduceCommand.mll` in Maya through Plug-in Manager

## Usage

The plugin is a custom command plugin, once the plugin has loaded, 

you should be able to run it with `maya.cmds`. 

I strongly suggest

using a mesh under 3000 vert-count as the algorithm is not optimized yet.

The plugin also only supports triangle meshes.

1. Select the mesh you want to reduce in the scene

2. Execute using `reduceCmd()` of desired reduce rate using `percentage` flag.

The `percentage` is how much vertices you want the mesh to remain compared to 

the original. (example: A mesh with 1000 verts will be reduced to

200 verts after running with`percentage=20`)

    ```python

    import maya.cmds as cmds

    cmds.reduceCmd(percentage=50)

    ```
