priority() const Returns the render priority of the part.
-
virtual const Mat4d &
transformation() const Returns the current transformation matrix for the part.
-
virtual void
setTransformation(const Mat4d &matrix) Sets the transformation matrix to use for the part.
-
size_t
count() const Returns the number of points in the part.

startPosition(size_t index) const Returns the start position of the arrow with the given index.
-
void
add(const Vec3d &startPosition, const Vec3d &endPosition) Adds an arrow to the part, specified with a startPosition and an endPosition.
The arrow head will be at the endPosition
-
void
add(const std::vector<Vec3d> &startPositions, const std::vector<Vec3d> &endPositions) Adds multiple arrows to the part.
-
void
set(size_t index, const Vec3d &startPosition, const Vec3d &endPosition) Sets the start and end position of the arrow with the given index.
