My hall environment is not properly displayed

My previous hall model can no longer be displayed/imported?

With the release of Halocline Layout & Performance in version 2022.4 only hall models in glTF format are supported. We no longer support the previous .assetbundle file format as of this release. An import of a CAD file is still possible.
If you currently have an existing hall model, we have converted it to the new gITF format for you and made it available to you separately. If you have any questions, please contact our support (support@halocline.io).

How do I import a gITF file into Halocline?

You can find instructions here: Import shopfloor environment

The hall model is not displayed correctly in Halocline Layout & Performance?

If the display in Layout & Performance is not as expected after the import, this can have various causes. Provide your contact person with this information Preparation of shopfloor environments.

The dimensions of my hall model are not correct in Layout & Performance. Which scale or unit of measurement do I have to choose for the export as glTF?

1.0 Unit = 1.0 Meter

In the hall model, there are areas that flicker unpleasantly. What is the cause of the flickering and how can I eliminate this problem?

If two surfaces with similar orientation are at almost identical positions, the distance to the camera at the overlapping surface is too similar for both surfaces, so that it is not clear which surface should be displayed first and which one afterwards (see Z-fighting). This can have the following causes:

1. The entire object is duplicated.
   This can occur if an object or structure is described multiple times in the underlying data (possibly by different data types, such as curves, solids, extrusion or polygon mesh) and is converted as glTF per data type during export.
   → Suggested solution: In this case, the objects that are redundant for the visual representation should be removed or deselected before export (see also Preparation of shopfloor environments).
2. Parts of an object overlap with that of another object
   Structures that are already simplified as CAD objects (for example, due to missing recesses in connecting pieces), or elements that are flush with an actually bounding volume, can also lead to Z-axis fighting.
   → Suggested solution: Adjust the overlapping face/edges on the solid or polygon on at least one of the two objects to increase the distance between the problematic faces.
3. The surface of an object behind is oriented in the wrong direction
   When CAD data is converted into polygon models, it may happen that the surfaces triangulated on one side (the normal vector of the polygon) point in the wrong direction. Since the polygons are rendered only from the front side in the real-time rendering engine used by Halocline Layout & Performance, the objects or surfaces with the normal vector pointing in the opposite direction are invisible.

• • Correction of the CAD model before conversion.
    This is especially useful if the problematic CAD object serves as a reference for several objects in the hall model:
    • simplify open curves and convert them into closed curves,
    • convert closed curves into (closed) surfaces,
    • simplify solid object if necessary.
  • Correction of the polygon model after conversion
    If the object already exists as a polygon model, an adjustment can be done as follows:
    • select incorrectly aligned surface and invert normal,
    • manually change the order of the vertices (see Face Culling - OpenGL Wiki),
    • recalculate the whole normal of the mesh (if function is available).

Parts of the hall model are invisible whether the corresponding surfaces are correctly represented in the CAD model.

If CAD data are converted into polygon models, it can happen that the one-sided triangulated surfaces (the normal vector of the polygon) point in the wrong direction. Since the polygons are rendered only from the front side in the real-time rendering engine used by Halocline Layout & Performance, the objects or faces with the normal vector pointing in the opposite direction are invisible. (See Back-face culling).
