+### Added new geometry loader to Cornerstone3D
+
+Aiming towards polySeg representations require support for loading a geometry. As part of this task a geometry loader were added to the cornerstone3D which can support loading and caching two geometries:
+
+- ContourSet: A set of 3D contours (list of contours each with a list of points)
+- Surface: A 3D surface (points and polygons)
+

+
+### Implemented the contour segmentation representation in Cornerstone3D
+
+The contour representation is the simplest representation of a polySEG segmentation. It is a set of 3D contours (list of contours each with a list of points). The representation
+utilizes the geometry loader to load the contours and render them in the cornerstone3D viewport using the vtkActors

+
+### Implemented the surface segmentation in Cornerstone3D
+
+The surface representation is a 3D surface (points and polygons). The representation utilizes the geometry loader to load the surface and render them in the cornerstone3D viewport using the vtkActors

+
+### Debugged the build for the WASM file to make it smaller
+
+The WASM file was too big to be used in the browser. The build was debugged to make it smaller. Tried the following with no success:
+
+- Making the biuld optimize for size instead of speed
+
+## Next Steps
+
+- Implement the OHIF side of the polySeg representation
+- Make the WASM file smaller to be used in the browser
 
 # Background and References
 
+[ICRPolySeg-WASM](https://bitbucket.org/icrimaginginformatics/polyseg-wasm/src/master/), a wrapper package that implements PolySeg for the Web written by ICR team. This work is sponsored by NCITA, a flagship multi-institutional collaboration between leading UK universities, funded by Cancer Research UK - ncita.org.uk. The functionality has now been integrated into the XNAT OHIF Viewer v3.5.0-RC1.
