Class Acts::Polyhedron¶
-
class Polyhedron¶
Struct which contains a cartesian approximation for any surface type.
It contains a list of cartesian vertices in the global frame, and additionally a list of lists of indices which indicate which vertices form a face. Each entry in
faces
is a face, which is in turn a list of vertices that need to be connected to form a face. This allows theobjString
method to produce a ready-to-go obj output.Public Types

using FaceType = std::vector<size_t>¶
Public Functions
-
Polyhedron() = default¶
Default constructor.
-
inline Polyhedron(const std::vector<Vector3> &verticesIn, const std::vector<FaceType> &facesIn, const std::vector<FaceType> &triangularMeshIn, bool isExact = true)¶
Default constructor from a vector of vertices and a vector of faces.
Note
This creates copies of the input vectors
- Parameters
verticesIn – The 3D global vertices that make up the object
facesIn – List of lists of indices for faces.
triangularMeshIn – List of lists of indices for a triangular mesh
isExact – A dedicated flag if this is exact or not
-
Extent extent(const Transform3 &transform = Transform3::Identity()) const¶
Maximum extent of the polyhedron in space.
- Parameters
transform – An (optional) transform to apply to the vertices for estimation the extent with respect to a given coordinate frame
- Returns
ranges that describe the space taken by this surface
-
void merge(const Polyhedron &other)¶
Merge another Polyhedron into this one.
- Parameters
other – is the source representation
-
void move(const Transform3 &transform)¶
Move the polyhedron with a Transfrom3D.
- Parameters
transform – The additional transform applied
Public Members
-
bool exact = true¶
Is this an exact representation (approximating curved spaces)
-
std::vector<FaceType> faces¶
List of faces connecting the vertices.
each face is a list of vertices v corresponding to the vertex vector above
-
using FaceType = std::vector<size_t>¶
