# KNN heat transfer

AN easy implementation of heat transfer for point cloud data with out any need to solve the heat equation or laplacian, just using the KNN algorithm.

This can be used in Data science, computational geometry (e.g. [Vector Heat Method](https://www.cs.cmu.edu/~kmcrane/Projects/VectorHeatMethod/paper.pdf)

 ) and mechanical engineering.

 

 ```python

 ##import your point cloud data

 

plydata = PlyData.read("./bun_zipper_res2.ply")

point = np.vstack((

    plydata['vertex']['x'],

    plydata['vertex']['y'],

    plydata['vertex']['z']

)).T

 

 

## feed point cloud to diffuse function

points = pd.DataFrame(point)

(data,indices) = diffuse(points,1,70,10)
