Qt3D: QPolygonMeshWithHole geometry

[ghorwin]

Hi there,

does anybody have a mesh implementation for a polygon mesh (ideally with hole) ready or does anybody know about a project using such a mesh?

If there's nothing like that available, I would create such a mesh myself - in such case I'd appreciate feedback/suggestions on the API. Currently I would favour something like:

// polygons defined 2D plane, n > 2
// with vectors of first and last segment must not be parallel
// inner polygon must not intersect with outer polygon, but may have a joined
// point, but no joined segments
QPolygonF outerPolygon = ...;
QPolygonF innerPolygon = ...;
 
QPolygonMesh * mesh = new QPolygonMesh();
mesh->setPolygon(outerPolygon);
mesh->setInnerPolygon(innerPolygon);
mesh->setMaxSegmentLength(0.1);

// polygons defined 2D plane, n > 2
// with vectors of first and last segment must not be parallel
// inner polygon must not intersect with outer polygon, but may have a joined
// point, but no joined segments
QPolygonF outerPolygon = ...;
QPolygonF innerPolygon = ...;

QPolygonMesh * mesh = new QPolygonMesh();
mesh->setPolygon(outerPolygon);
mesh->setInnerPolygon(innerPolygon);
mesh->setMaxSegmentLength(0.1);

Polygon would be created in x-z plane such, that p0 is the origin (0,0,0) (translating all polygon points accordingly).


What do you think?
