Heightmap
A Heightmap is a 2D asset that can generate 3D voxel data from image-based layers.
It provides a different workflow from direct voxel modeling by letting you design shapes in 2D and convert them into voxel-based forms.
How It Works
A Heightmap stores pixel data with height information. When used in Foxel, this data can be turned into 3D voxel geometry.
This makes Heightmaps useful for forms that are easier to draw as an image first and then build into depth.
Key Features
2D-based workflow: Heightmaps are edited as image-like data rather than as voxel objects.
Height-driven voxel generation: Pixel values are used to produce 3D voxel shapes.
3D preview and use: Heightmaps can be used as source data inside voxel workflows.
Alternative content creation method: They offer a fast way to generate structured voxel forms from 2D input.
Typical Uses
Heightmaps are commonly used for:
- terrain and landscape-like shapes
- walls, reliefs, and surface details
- designs that are easier to sketch in 2D first
- quickly generating voxel forms from image-based data
Heightmaps are useful when a shape is easier to describe through height and silhouette than by modeling it voxel by voxel.
