Description

Details

SurfacesPoints_normalOffset

#define SurfacesPoints_normalOffset 3

The offset to read the normal values in poly_points.


SurfacesPoints_translationOffset

#define SurfacesPoints_translationOffset 6

The offset to read the translation values in poly_points.


SurfacesPoints_userOffset

#define SurfacesPoints_userOffset 9

The offset to read the user values in poly_points.


isosurfacesPointsAllocate ()

void                isosurfacesPointsAllocate           (SurfacesPoints *points,
                                                         int nsurf,
                                                         int npolys,
                                                         int npoints);

Allocate the arrays to store a set of points.

points :

a pointer on a set of points (not allocated) ;

nsurf :

the number of stored surfaces ;

npolys :

the number of stored polygons ;

npoints :

the corresponding number of points ;

isosurfacesPointsCheck ()

void                isosurfacesPointsCheck              (SurfacesPoints *points);

A debug routines to check that all pointers and size are relevant. It should not be used outside a debug area because it can be slow.

points :

a set of points.

isosurfacesPointsFree ()

void                isosurfacesPointsFree               (SurfacesPoints *points);

Free all allocated arrays of the given set of points. The point structure itself is not freed.

points :

a set of points.

isosurfacesPointsInit ()

void                isosurfacesPointsInit               (SurfacesPoints *points,
                                                         int bufferSize);

Initialise a SurfacesPoints structure. It must be done before any use.

points :

a pointer on a set of points (not initialised) ;

bufferSize :

the number of additional data to coordinates and normals.

isosurfacesPointsRemove ()

void                isosurfacesPointsRemove             (SurfacesPoints *points,
                                                         int pos);

Remove the points belonging to surface number pos.

points :

a set of points ;

pos :

an integer between 0 and points->nsurf.

isosurfacesPointsTranslate ()

void                isosurfacesPointsTranslate          (SurfacesPoints *points,
                                                         float xyz[3]);

In devel...

points :

a set of points.

xyz :

a given translation in cartesian coordinates.
