2D AABBTree in CGAL with custom property map

Asked 2021-Mar-01 at 21:55

I am trying to create an AABBTree for checking in which triangle of a 2D mesh some points are. To do that, I am using CGAL, in particular, the Polygon_mesh_processing package and the location functions. However, this feels an impossible task to me.

Since I want to check several points and I care about performance, I want to build an AABB first. To do that, I need the PMP::build_AABB_tree function, which receives a mesh and the AABBTree.

In this particular case, the mesh is of type CGAL::Surface_mesh, with a Simple_cartersian kernel. The query points are also 2D. According to documentation, I need to provide a ReadablePropertyMap which converts my 2D points into 3D points.

I do this with the following:

QUESTION

Is it possible to access spatial graph node id of SpatialSurfaceMesh?

Asked 2020-Nov-17 at 08:42

Microsoft.MixedReality.QR API provides spatial graph node id for detected QR codes. I need to access spatial graph node id of Windows.Perception.Spatial.Surfaces.SpatialSurfaceMesh class (to use with OpenXR XR_MSFT_spatial_graph_bridge extension). Is it possible?

I've tried to use SurfaceMesh.SurfaceInfo.Id property. But it seems that's not the id OpenXR is looking for.

...

ANSWER

Answered 2020-Nov-17 at 08:42

Actually, SpatialSurfaceMesh doesn't expose its underlying spatial graph node like QR codes or SceneUnderstanding, it is difficult to use the SpatialSrfaceMesh's SpatialCoordinateSystem with the OpenXR bridge extension. And in this case, SceneUnderstanding mesh should be better for all purposes except occlusion. So, it is recommended that you supersede SpatialSurfaceMesh with SceneUnderstanding to enable the OpenXR bridge extension.

In addition, the example of this feature has been arranged into our development schedule, please take an eye on our documentation.

How can I create a 3D cubic-bezier curved triangle from 3D points in Three.js?

Asked 2019-Jul-15 at 16:59

Following this topic, I am trying to generate a 3D curved triangle as a NURBS surface, but I don't understand how to set up my 3D points to do that.

Here is the current implementation :

ANSWER

Answered 2019-Feb-21 at 21:14

In your code you use NURBSSurface function from NURBSSurface.js file, that function uses NURBSUtils.calcSurfacePoint function from NURBSUtils.js file. But the calcSurfacePoint calculate point for standard NUBRB surface where where parameter are from rectangle (u,v) wiki.

You will not generate "3D cubic bezier triangle" in this way - to do this you need write your own code which will use bezier-triangle formulas (where the input parameters are triangle points in Barycentric_coordinate_system).

ANSWER

Answered 2019-May-03 at 07:10

You need to use the property maps of your SurfaceMesh. If and only if the OFF file has colors (meaning the first indication is COFF and not OFF on the first line), and there are colors per vertices and not only per face, then your SurfaceMesh will have an internal property map called "v:color". You can access it by calling

QUESTION

Substract closed mesh from surface (CGAL?)

Asked 2019-Jan-23 at 15:56

I have the following problem, best described with the picture below.

I have a surface in 3D, so it can have vertical overlap and is a non-closed mesh. And I have an object which I want to subtract from it. The green+yellow area is the original surface, the red lines outline a sphere (as triangulated mesh, not a primitive). The yellow area is the part of the surface intersecting the sphere that needs to be removed from the original surface. The green area is the result of the subtraction: the surface that is needed.

I am already using the CGAL library, but still new to it, so a solution using CGAL would be the most preferred. However if somebody has a solution without CGAL that would be welcome as well.

The best way I can see would be to give the surface a slight thickness (keeping the current surface as the bottom). And then use Nef_polyhedron_3 to substract the other object, then convert to Polyhedron_3 and only keep the bottom faces. But this seems like a bit of a hack.

EDIT: Using the proposed solution I get very close, but I am unable to clip to the correct side using the reversed normals as proposed, using the following code. I also tried to see if face vertex ordering (clockwise / counter clockwise) has any effect, but it seems not to have any.

ANSWER

Answered 2017-Jul-31 at 06:57

This is a classical mistake: removing elements you are iterating on. In this particular case, you are removing edges while iterating over edges of face. It is unlikely you'll find the initial edge to stop the iteration, thus the infinite loop.
