Module Description

The Modelmaker is used to create 3D surface models from segmented image data, called label maps. Label maps can be the result of automated segmentation or interactive editing. References give more details on the algorithm.

Use Cases

Most frequently used for these scenarios:

• General Usage: Select an input volume from the label map volumes that are present in the scene. Create a new model hierarchy node. Pick a label, range of labels, or all, from which to generate a surface model. Press Apply.
• Use Case 1: After using the Editor module to segment a volume, use this module to generate a 3D surface of one segment.
• Use Case 2: When creating models from an image in which the label of interest touches the boundaries of the image, the resulting model has no vertices defined for the surfaces that touch image boundaries. Use the CropVolume module and extend the ROI beyond the image boundary. CropVolume will initialize voxels outside the image with 0s, essentially creating a padding around the volume.
• Use Case 3: After segmenting a whole region of the body, you can generate all the surface models at once by selecting the Generate All Models option.
