Remeshing. The calculated 3D model consists of multiple triangles. In gener-
al, the lengths of triangle sides can differ greatly. For some CAD applications,
it is much easier to work with models which consist of identical triangles. For
this purpose, a remeshing procedure is used. Specify the required length of
the triangle side
(Edge Length)
as an additional parameter.
If during the remeshing process the Edge Length parameter greatly ex-
ceeds the resolution of the 3D model, the level of detail of the new model
will decrease. But if the Edge Length value is lower than the 3D model
resolution then the size of the new model and its processing time will in-
crease.
Simplification.
The mesh of the resulting model may not be optimal for
some applications because it contains too many polygons. This can make
its further processing more difficult. In order to optimize a model with mini-
mum degradation of accuracy the simplification algorithm can be used. The
value of
Amount of faces in the simplified mesh
specifies the extent of ge-
ometry simplification. (Example, if the initial model has 1,000,000 polygons,
then reducing it to 20% of the original will yield a model which consists of
200,000 polygons). By checking the Absolute
(Absolute value
) parameter you
can specify the number of polygons in the final model. Resulting model de-
tailing will vary depending on the specified number of polygons. The more
polygons used, the more detailed the 3D model will be, but at the same time,
more time will be required for its processing.
Texture mapping
Calibry scanners are equipped with a color camera which allows you to take
images of three-dimensional surfaces with texture. Texturizing is performed
by projecting separate captured color frames onto a finished 3D model. The
Texture size can be specified manually by choosing one of three provided op-
tions: 1024 × 1024, 2048 × 2048 or 4096 × 4096. The larger the size, the more
exact and sharp the result will be, and, accordingly, the more time required
for 3D model processing.
It is recommended to use simplification prior to texture mapping. Simpli-
fication significantly reduces the time of texture mapping.
