Iso Extrude

Overview

An advanced low-level node that extrudes a footprint into an isometric solid (IsoItem). Use it only when you need a free-form shape that the standard workflow (iso_item_builder or block primitives) cannot create.

Usage tips

• Consider the standard routes first: iso_item_builder for map-like assets and block primitives for basic shapes. This node is a supplemental free-form route.
• The output is an IsoItem. Place it into an IsoWorld with iso_place. To combine several items into one asset, use iso_assemble before placement.
• The input path is normalized to the item's local origin. Its original 2D position is not retained; set the world position with iso_place.
• The current implementation is a solid-color proof of concept and may change in the future.

• iso_place — places the IsoItem into an IsoWorld

• iso_assemble — combines several IsoItems into one asset

• iso_world_compose — combines already placed IsoWorlds

Notes

• In the long-term design, this is a free-form route that supplements semantic primitives such as IsoBlock, not the primary workflow.
• Visible faces are generated with simple face tests.
• Materials currently support only solid colors.
• The current v1 is a polygon-extrusion proof of concept intended to be replaced by a footprint -> occupancy grid -> exposed faces pipeline.
• Reference shapes such as ClassicCube are expected to use a dedicated primitive and raster style instead of being built here.
