Analýza síťového modelu

analýza sítě (mesh analysis) je užitečný nástroj pro zobrazení atributů sítě, které mohou mít význam v určitém případě využití. Analýza sítě pracuje v editačním režimu objektu a vyznačuje oblasti pomocí barvy. Červené odpovídají vysokým hodnotám, modré nízkým a šedé oblasti značí hodnoty mimo rozsah.

Currently the different modes target 3d-printing as their primary use.

Overhang

Overhang

Extrusion 3D printers have a physical limit to the overhang that can be printed, this display mode shows the overhang with angle range and axis selection.

Thickness

Thickness

Printers have a limited wall-thickness where very thin areas can't be printed, this test uses ray casting and a distance range to the thickness of the geometry.

Intersections

Intersecting faces

Another common cause of problems for printing are intersections between surfaces, where the inside/outside of a model can't be reliably detected.

Unlike other display modes, intersections have no variance and are either on or off.

Distortion

Distorted Faces

Distorted geometry can cause problems since the triangulation of a distorted ngon is undefined.

Distortion is measured by faces which are not flat, with parts of the face pointing in different directions.

Sharp Edges

Sharp edges

Similar to wall-thickness, sharp edges can form shapes that are too thin to be able to print.

There are some known limitations with mesh analysis
  • Currently only displayed with deform modifiers.
  • For high-poly meshes is slow to use while editing the mesh.
