WEMLevelSetFilter¶

MLModule¶

author	`MeVis Medical Solutions AG`
package	`MeVisLab/Standard`
dll	`MLOpenVDB`
definition	MLOpenVDB.def
inherits from	`WEMLevelSetFilterBase`
keywords	`gauss`, `mean`, `meancurvature`, `laplace`, `median`, `erode`, `dilate`, `close`, `open`

Purpose¶

The WEMLevelSetFilter allows for applying level set filters to a WEM by transforming the mesh into a level set voxel grid, applying a filter, and remeshing the result.

It utilizes the OpenVDB library.

filterChain¶

name: filterChain, type: String¶

Sets the filter chain is used when Mode is set to FilterChain.

It specifies a chain of filters to be applied, one filter per row. The available filters are:

gaussian [iterations]
meancurvature [iterations]
mean [iterations]
median [iterations]
laplacian [iterations]
opening [distance]
closing [distance]
dilate [distance]
erode [distance]

Comment chars are //, so you can comment the filter chains.

The following will perform two Gaussian smoothing iterations and one dilate iteration with offset 3.5:

// first two gaussian iterations
gaussian 2
// then a dilation
dilate 3.5
