Object Info, Mesh Info and Points Info on the Inspect tab show technical data about the selected object. Object Info sums up the whole object, for example the number of holes and components before you print a model. Mesh Info shows single triangles, edges and vertices of a mesh, and Points Info analyzes the neighborhood of a single point of a point cloud.
| Tool | Shows | Use it to |
|---|---|---|
| Object Info | Counts, holes, components, area, volume, box and memory of the selected object | Check a model before printing or repair |
| Mesh Info | One triangle, edge or vertex of a mesh, picked by its ID | Find a defect by its ID, walk along the border of a hole |
| Points Info | The neighbors of one point of a point cloud and a plane or a surface fitted to them | Check the density and noise of a scan |
The most common numbers are always visible without these tools: the Information panel under the Scene Tree shows the box size, triangles, vertices, edges, volume, area, average edge length and components of a selected mesh.
Object Info
Select an object and click Inspect › Object Info. The panel starts with Selected object and lists what applies to the object type. For a mesh it shows, among others:
- class (for example Mesh), mem and GL mem (memory used);
- components, holes, vertices, triangles and edges (with the selected number, if any);
- area, volume and avg edge len;
- box min, box max, box center and box size.
For a model you want to print, check that holes is 0 and components is 1. If not, see Fill Holes and the Mesh Healer. With no object selected, the panel says No object selected.
Mesh Info
Mesh Info shows the data of one element of the selected mesh. It is a tool for detailed checks, for example when a report or a script gives you the ID of a bad triangle.
- Select a mesh and click Inspect › Mesh Info.
- Choose the mode and type the ID of the element, or step with − and +.
Tri., Edge and Vert modes
| Mode | Field | What the panel shows |
|---|---|---|
| Tri. Mode | Tri. Id | Edge and neighbor triangle IDs, the three vertices with coordinates, Normal, Area, Circum-Radius, Aspect Ratio |
| Edge Mode | Edge Id | The edge vertices and triangles, Length, Dihedral angle, Cotan weight |
| Vert Mode | Vertex Id | The vertex coordinates, its edges and triangles |
In Edge Mode, Next Origin Edge, Prev. Origin Edge and Sym. Edge move to the neighbor edges. On the border of a hole, Next Boundary Edge and Prev. Boundary Edge walk along the border.
Show Selected Item (on by default) highlights the current element on the model. Show Triangle Labels, Show Edge Labels, Show Vert Labels and Show Neighbor Labels write the IDs on the model.
Points Info
Points Info analyzes a point cloud around one point. Use it to see how dense and how noisy a scan is.
- Select a point cloud and click Inspect › Points Info.
- Pick the point: type its Point Id or step with − and +. XYZ shows its coordinates, and Normal its normal if the cloud has normals.
- In Neighborhood, choose Radius (all points within this distance; Points in Ball shows how many) or Number of Points (the given number of closest points; then Num. Points sets it).
The neighbor points become selected, and the Information panel shows their number. Draw sphere shows the neighborhood as a sphere; with Center in a point on, the sphere is centered in the picked point.
Under Approximation, Draw plane and Draw quadric fit a plane or a curved surface to the neighbors; Draw plane center, Draw quadric center and Draw basis add their centers and axes. Reverse Z direction and Normal-based weights (available only for clouds with normals) change how the surface is fitted. Resolution sets how detailed the drawn surface is, and Transparency how opaque.
