## JJJ.7 Using Colored Vertices Instead of Texture

Use-case: A single surface record of a patient is made, for example teeth, nose, or breast. If third party software does the post-processing only the point cloud needs to be stored. Gray or color values can be assigned to each point in the point cloud.

The point cloud is stored in a Surface Scan Point Cloud instance. A study with a single series is created. One or both of the attributes Surface Point Presentation Value Data (0080,0006), or Surface Point Color CIELab Value Data (0080,0007) may be used to assign gray or color values to each point in the point cloud.
