Class Acts::IVisualization3D

class IVisualization3D

Partially abstract base class which provides an interface to visualization helper classes.

It provides a number of methods that all the helpers need to conform to.

Subclassed by Acts::ObjVisualization3D< T >, Acts::PlyVisualization3D< T >

Public Types

using FaceType = std::vector<size_t>

Public Functions

virtual void clear() = 0

Remove all contents of this helper.

virtual void face(const std::vector<Vector3> &vtxs, ColorRGB color = {120, 120, 120}) = 0

Draw a face that connects a list of vertices.

Note

Depending on the helper implementation, out of plane vertices might be handled differently.

Parameters
  • vtxs – The vertices that make up the face

  • color – The color of the face

virtual void faces(const std::vector<Vector3> &vtxs, const std::vector<FaceType> &faces, ColorRGB color = {120, 120, 120}) = 0

Draw a faces that connects a list of vertices - expert only.

Note

Depending on the helper implementation, out of plane vertices might be handled differently.

Parameters
  • vtxs – The vertices that make up the faceS

  • faces – The face presectiotions (i.e. connecting vertices)

  • color – The color of the face

virtual void line(const Vector3 &a, const Vector3 &b, ColorRGB color = {120, 120, 120}) = 0

Draw a line from a vertex to another.

Parameters
  • a – The start vertex

  • b – The end vertex

  • color – The color of the line

virtual void vertex(const Vector3 &vtx, ColorRGB color = {120, 120, 120}) = 0

Draw a vertex at a given location and a color.

Parameters
  • vtx – The vertex position

  • color – The color

virtual void write(std::ostream &os) const = 0

Write the content of the helper to an outstream.

Parameters

os – The output stream for file

virtual void write(const std::string &path) const = 0

Write the content of the helper to an outstream.

Note

wil change to std::filesystem::path once gcc9 is standard

Parameters

path – is the file system path for writing the file
