Welcome to Sluice.

Sluice is for inspecting Gendl models while you're developing them. You can see your model structure in the tree at the upper left.

The display list of this viewport is empty. Click a node in the tree to apply the ADD-LEAVES operation.

The rendering mode is Wireframe (this viewport's View menu). Wireframe is a pannable, zoomable SVG; the shaded modes are navigable X3D scenes, in either of two X3D browsers. The X_ITE scene offers a headset button where WebXR is available.
