Sets the alpha value to be used when running an alpha test. The material will not be renderered if the opacity is lower than this value. Default is 0.

bitmaptexture String <optional>

URL to the color map, can be a data URI. Default is null. The texture map color is modulated by the material color.

URL to the metalness map, can be a data URI. The blue channel of this texture is used to alter the metalness of the material.

SceneAsset

Scene asset

This definition describes an asset containing geometry and/or material items.

If an asset contains no material items, it may instead link to another asset which does. This makes it possible to replace geometry and materials separately - if a material is replaced, that change is reflected in all the geometry objects which link to it.

All properties can be optional depending on the context.

If the API returns an asset, it usually includes all properties.

For geometry updates using updateAsync one can send only the properties which need to be changed, along with the id of the object to be changed.

See:
Type:
  • Object
Properties:
Name Type Argument Default Description
id String

The unique id of this asset. Ids of existing assets can be retrieved using get. This id should be remembered to reference the asset later, e.g. to update or remove it.

name String <optional>

The human readable name of the asset

group String <optional>

If provided, defines a logical group which this asset belongs to. The group can be used as a filter in calls to get.

material String <optional>

Id of the material asset to be used for the geometry defined by this asset. Can be ommited if this asset contains its own materials (see property content), or if the geometry in this asset has embedded materials. Takes precedence over materials defined in content.

version String <optional>

Unique version id of this asset. If the same asset is provided again later with the same version id, caching might improve performance. A random version id will be created if none is specified.

bbmin Point3dArray <optional>

Minimum coordinates of the axis-aligned bounding box of the geometry in this asset. If not provided, this will be computed. Not used for material assets. Set this to null when updating geometry and you don't know the updated bounding box, which will cause the bounding box to be recomputed in the viewer. If you don't do this, the previous bounding box information will persist.

bbmax Point3dArray <optional>

Maximum coordinates of the axis-aligned bounding box of the geometry in this asset. If not provided, this will be computed. Not used for material assets. Set this to null when updating geometry and you don't know the updated bounding box, which will cause the bounding box to be recomputed in the viewer. If you don't do this, the previous bounding box information will persist.

duration Number <optional>

dragPlaneNormal Point3d | Point3dArray <optional>

Optional normal to the plane which should be used for dragging. If not specified, dragging will happen in a plane normal to the viewing direction. Requires an InteractionGroup to be specified.

addEventListener function <optional>

When the API returns an asset, it adds this function to allow registering to events limited to this specific object (scene path). Refer to the documentation of the global addEventListener function.
