The wide range of formats and models for 3D applications create interoperability challenges that can make even a headless horseman scream with fright. This webinar will treat you to basic 3D concepts and will teach you how to tackle 3D transformation challenges using FME.
3. ● We are adding more 3D capable
formats
● Existing formats (ie. Geodatabase)
adding 3D
● Most users unfamiliar with geometry
types
● Transforming between geometries
types often required
9. Surface
Face
➢ Basic 3D Unit
➢ Bounded by Polygon
CompositeSurface
➢ Collection of connected Faces
➢ Consistent front/back directions on
Faces
MultiSurface
➢ Collection of Faces and/or
CompositeSurfaces
11. Solid
Box
● 3D solid primitive
● Not really useful
Extrusion
● Base Face and
extrusion
direction/distance
BRepSolid
● Solid defined by
closed
CompositeSurface
boundary
12. Geometry Structure
Multi Level
● Hierarchy Structure reflected in geometry
● Each level can be named
Traits and Attributes
● Attributes only on feature
● Traits are attributes on geometry
Geometry Query
● Operate on desired geometry level without
deconstructing aggregate
