The CloudWorx module in 3DReshaper allows the user to open and use extremely large data sets in the form of Leica Cyclone and JetStream databases. The ability to open such large files without the exporting and importing step saves time and increases productivity. Learn to use the tools in the CloudWorx module by opening a Leica Cyclone ModelSpace view and evaluate an area of a bridge to see how it has changed over time.
Tunnel point clouds are usually hard to clean. Many noisy or aberrant points (vent pipes, cable, light...) need to be removed from the inside of the tubular shape. This process is necessary if you want to make an accurate inspection of the tunnel. 3DReshaper brings a solution to ease the filtering step.
In 3DReshaper, you can create light models of buildings without filtering the scan. In this exercise, we will create a light model of a complex building, and compute a 2D plan form the simplified model).
In 3DReshaper, you can automatically remove the extraneous points like vegetation to keep only the ground. In this exercise, we will automatically generate the mesh of the ground and use this mesh to extract contour lines and breaking lines such as curbsides.
In 3DReshaper, you can compute cubatures. In this exercise, we are working on the analysis of a stockpile of ore and we will compute cubatures on meshes with different level of details in order to find the volume of ore extracted in the mine.
- 3D Meshing and Texturing (refinement from the point cloud and with interpolated new points - heritage)
Depending on the quality of the original point cloud (noisy and aberrant points, missing parts, ...), it is often useful to mesh first with a big noise reduction parameter and then refine the rough mesh one or several times. In this exercise, we will see how to get a nice and accurate mesh using different meshing steps (rough mesh and refined meshes), to apply a picture and to decimate the number of triangles while keeping the realistic rendering.
In 3DReshaper, you can process a tunnel inspection thanks to several dedicated functions. In this exercise, we will see how to compute a neutral axis, create cross sections along this axis, compare cross sections, print in a specific template and create a video animation.
In 3DReshaper several meshing commands are available. In this exercise, we will see how to mesh a noisy cloud using two mesh refinements (existing + interpolated or new points) + smoothing + sharp edge reconstruction.
In 3DReshaper, you can calculate volumes in different situations: closed surfaces, at a certain level of liquid, embankment and excavation for two superimposed surfaces. In this exercise, you will compute volumes and cubatures on a lake and on a tank.
Because of reverse-engineering needs, you need to generate from a digitization a CAD model (such as IGES or STEP), usable in Computer-Aided Design, Manufacturing or Engineering software. In this exercise, we will see how to how to convert a meshed model into a CAD model.
In 3DReshaper, you can apply a texture on a mesh by clicking several reference points or by entering camera parameters. In this exercise, you will map a texture on a mesh thanks to reference points and you will see how to adjust textures when several pictures are applied.
Comparing two shapes or two contours to know the gap or distance between them is required when you want to inspect a imported theoretical geometry with the corresponding measured model or when you want to compare two objects measured at different times (a DTM for instance). In this exercise, we will see how to how to align and place two objects in the same coordinate system in order to make a 3D comparison.
In 3DReshaper several meshing commands are available depending on the model and the application. In this exercise, we will see which meshing strategies can be applied (regular mesh + local improvement and mesh refinement using the points from the cloud).
Sometimes, it is necessary in a point cloud to cut apart the points that are not relevant or must be separately processed in your application (e.g. monuments and trees on a DTM). In 3DReshaper, there are several ways of processing the point clouds (bad points removing or selecting, etc.). In this exercise, we will see how to split or explode a point cloud in different parts manually or according to a distance parameter. The 3D meshing while keeping all points will also be presented.
