I am looking to implement a dynamic cropping feature, that has 3 main requirements
- The user is able to dynamically draw an area within the point cloud to crop (a rectangular selection)
- Only render/display the points within the bounds of the selected horizontal plane
- Calculate the number of points that are contained within the selected area.
From looking at the available cesium features and sandcastle examples, I figure a combination of using ClippingPlanes and BoundingSphere (or BoundingRectangle) elements
would be most suited to implementing these features.
Does this sound feasible or are there other features of Cesium that would be better suited to implementing these requirements?
