Using the default 3D engine

OGL was seleceted as the default 3D engine for sparcl, because it is very small and still manages to hide away the specifics of WebGL.

The idea is, that the 3D engine can ‘easily’ be replaced by another one, but still being able to use the default Viewer and XR engine. For this, we will have some kind of API defined, but this is not yet accomplished, unfortunately.

To give you an overview what can be used right now, we added a list with currently available functions. Please be aware that this list is likely to change in the future.

init()

remove(3dObject)

clearScene()

render(time, view)

stop()

addModel(url, position, orientation, scale)

addObject(position, orientation, description)

addPlaceholder(keywords, position, orientation)

addExperiencePlaceholder(position, orientation)

addClickEvent(3dobject, handlerFunction)

setWaiting(3dObject)

getExternalCameraPose(view, matrix)
