- use std::vector when buffer can be reserved in advance and cannot be too large,
- else use std::deque
I expect gains in terms of speed and memory fragmentation.
Examples:
- MFC demo can now load bimba_range_images.off (range images of the Bimba con Nastrino scan, 3.8 millions points).
- Poisson reconstruction is 10 seconds shorter on Chinese_dragon_Minolta_point_set_225kpts_with_jet_normals.xyz.
Note that Vector_3 is the concept of a normal vector (always) oriented.
- Point_with_normal_3 is now templated by the normal type.
Types currently available are:
-> Vector_3 (the default)
-> Orientable_normal_3 (used by Point_set_3 for point cloud processing)
-> Lightweight_vector_3 = a normal whose vector is allocated only if not zero (used by Poisson 3D triangulation).
We have now 2 corresponding concepts:
-> PointWithNormal_3 = a point + a normal (always) oriented.
-> PointWithOrientableNormal_3 = a point + a normal oriented or not.
The purpose is to save memory space and to better document the requirements of algorithms processing normals.
Enforced CGAL_NDEBUG rule:
- code under include/CGAL/ and src/ must not use NDEBUG and assert(), but CGAL_NDEBUG and CGAL assertion macros.
- code under demo/, examples/ and test/ must use NDEBUG and assert().
Added _HAS_ITERATOR_DEBUGGING=0 to .vcproj makefiles to speed up VC++ 2005 debugger.
Removed CGAL_SURFACE_RECONSTRUCTION_CHECK_EXPENSIVE from .vcproj makefiles (unused).
- m_points[] array of points + normals.
- the m_poisson_dt 3D triangulation used by the m_poisson_function implicit function.
Only 1 form is visible on screen and editable at a given time. This is controlled by m_edit_mode.
A new class Point_set_3 represents an array of points + normals of type PointWithNormal_3 (in fact Gyroviz_point_3 to support algorithms specific to Gyroviz). It provides accessors (points and normals iterators, property maps), OpenGL rendering and bounding box.
File >> Open fills the point_set.
Algorithms menu is split into:
- Processing menu which modifies a point,
- Reconstruction >> Poisson sub-menu which converts the point set to a triangulation 3 and then solves the Poisson equation over it.
