New in ShapeWorksStudio

Mesh Support

As of ShapeWorks 6.0, we added mesh support to ShapeWorksStudio including loading meshes, optimizing shape models directly on meshes, and visualizing meshes with scalar feature values. Meshes can store values at vertices such as "cortical thickness", or "fibrosis” and ShapeWorksStudio uses them in a similar manner as feature maps/volumes.

We also added a new surface reconstruction method with support for both mesh or image inputs. This method is much faster and is the new default.

Improved Studio Interface

As of ShapeWorks 6.0, we added support for automatic glyph sizing, draging/dropping of images and meshes. Scalar bar color is now opposite of background color (e.g., when background is white, text should be dark) (user request).

Surface Reconstruction

ShapeWorksStudio provides a particle-based surface reconstruction that can reconstruct high quality surface meshes with fewer number of particles. See How to Analyze Your Shape Model? for details about the method.

With particle-based surface reconstruction, there is not need to optimize denser particle systems (i.e., with more particles) to reconstruct surface meshes with subvoxel accuracy Reconstruction error vs number of particles

Dynamic Loading

ShapeWorksStudio support load-on-demand, which makes it more scalable by supporting loading in order of 100s of samples. For instance, an old small project that took 10+ seconds to load now starts instantly in Studio.

Live Particles Movement

ShapeWorksStudio allows for live introspection of the correpsondence placement optimization process and the ability to abort the optimization at any time (e.g., changing algorithmic parameters).

Feature Maps

ShapeWorksStudio has the ability to integrate feature maps. A feature map is a 3d image volume that contains scalar values to be associated with each shape’s surface. For example, this could be raw or processed CT/MRI data. The feature map can be displayed for each surface by choosing the desired feature map in the feature map combobox at the bottom of the screen. After the correspondence is generated, the average feature map can be displayed on the mean shape in the analysis tab.
