+## Component roadmap
+From the 3/5/2024 meeting, the architecture of the different grasshopper components was discussed as following:
+- [ ] PLY loader point cloud: @eleni: loads the pointcloud ply files and converts it into rg.PointCloud (+ cvt submodule)
+- [ ] PLY loader mesh: @eleni: loads the mesh ply files and converts it into rg.Mesh (+ cvt submodule)
+- [ ] Global registration: @andrea: to align the scan to the reference model
+- [ ] Refined registration: @andrea: to refine the alignement
+- [ ] Semantic segmentation additive: to identify the pieces or joints in the point cloud
+- [ ] Semantic segmentation subtractive: to identify the pieces or joints in the point cloud
+- [ ] Per-joint refinement to refine the global registration to each joints (only in the "substractive" case)
+- [ ] Error estimation to evaluate the error for each piece or joint
+- [ ] Error visualisation to visualise the error, only converts the data from error estimation, no calculation.
+The brep element in the graph is only here to visualize the fact that we need the breps as data, but it is not a diffCheck component.
