Triply Use Case 10: Visualization settings for 3D data

Description

When I have a 3D dataset in GeoSPARQL, I want to be able to configure the way in which this dataset is visually presented.

For example:

• I want to be able to set a legend of colors and labels that apply to different types of 3D objects.
• I want to be able to set the transparency of 3D components. This allows me to configure a view of a tall building, where the apartments inside the building can be seen (through a transparent outside wall), and where the floors underneath the ground can be seen (through a transparent background map / 3D base tile).

(This is similar to how HTML has the ability to configure styling in CSS. Similar to HTML/CSS, styling for GeoSPARQL 3D may be positioned in a separate, accompanying standard.)

Actor

• A data scientist who prepares a 3D view for users.
• Users of 3D data, who want to have a nice and intuitively configured view.

Preconditions

• 3D GeoSPARQL data.
• Ideas on how to visualize this to users (e.g. colors, transparency).

Postconditions

• A fully configured view on 3D data, including transparency, colors, and legends with labels.

Steps

1. I load a graph of 3D data into my triply store.
2. I create two separate graphs with 3D styling information. The two different styles highlight different aspects of the 3D data.
3. When users interact with my 3D GeoSPARQL data, they can switch between the two different styles, which allows them to immediately focus on the right details.

@wouterbeek I believe that I covered this subject in https://github.com/opengeospatial/ogc-geosparql/issues/584 Please have a look at CityGML Appearance module, if there is anything missing there: https://docs.ogc.org/is/20-010/20-010.html#toc31
