Hello,

In our 3D chart, there could be some orbitary number of layers. These layers could be continuous in x direction, overlapping ( inner & outer meshes)  or resting one top of another mesh etc..

compared to other surface serieses like TriangulatedSurfaceSeries & MeshSurfaceSeries, we found the NGridSurfaceSeries suits better for our requirement . 

With Triangulated / Mesh  serieses: When there are some points which are not connected to the ground, they will be rendered as they are present,  and in some cases, it is seen as the layers hanging in the air, which is not correct/ expected behaviour. We need to connect those hanging points to ground.

With GridSurfaceSeries: When the complete data points are present within the given grid dimensions, the mesh is closed from all the sides. Basically all the points which are hanging in the air are connected to the ground,  even through there are no explicit data points on the ground.  This is some what related to our requirement, but not completely.

The problem is when the data points exists, out the given grid dimesions, the mesh is not closed. It shows a hallow region. Inner contents are visible from the hallow region. Also in case of layers which rest on top on another, if we connect the respective points of each layer to the ground, that is also not the correct behavior.

We need support on the following questions.

1) Which surface series suits to our requirement? Is the GridSurfaceSeries the best one? or is there something else which we can look for?

2) Is there any way to keep the GridSurfaceMesh always closed. For a given data points, within in the given Grid dimesion, can we have a closed mesh?

( Refer the attachments Closed Mesh.png & HallowMesh.png)

3) Can we control the closure of the Grid surface mesh on a given custom point? instead of always connecting to the Ground?

Thanks a lot in advance.

 

Best regards

Hello,

In general, none of the surface series is connected with the chart floor (or ground as you call it), unless you explicitly specify data points for this purpose. This behavior is by design and in this sense - it is correct.

It is possible to use one or several additional mesh surface series in order to draw vertical surfaces that connect the "hanging" data points with the chart floor. This approach is straight-forward for grid and mesh, since it is easy to determine the outer contour of such surfaces. For triangulated surfaces this approach can be applied too, but you need to know the convex hull of the set of points that form the surface.
