Geometry — surface parameterization

SurfaceParamerterizer lives in its own page so Breathe does not emit duplicate CGAL typedef declarations that also appear in primitives.h.

class SurfaceParamerterizer

#include <surface_paramerterizer.h>

Public Functions

glm::vec3 get_point_on_mesh()

inline bool is_valid() const: Check if parameterization was successful.

glm::vec3 lift_point(glm::vec2 uv_point)

Lifts a point from normalized UV space [0,1]^2 to 3D space on the surface.

Parameters:: uv_point – The normalized UV point to lift (coordinates in [0,1])
Returns:: The lifted 3D point on the surface, or glm::vec3(0,0,0) if outside

glm::vec2 project_point(glm::vec3 xyz_point)

SurfaceParamerterizer(std::string surface_mesh_path)
