3D View
Interactive 3D surface view of a DATA_FIELD. Use the mesh input for geometry and optionally a second map input for coloring. Drag to rotate, middle-drag to pan, and right-drag or scroll to zoom.

Description |
| colormap |
dropdown |
auto |
Colormap preset applied to the surface; hidden when colormap_map is connected |
| z_scale |
FLOAT |
1.0 |
Height exaggeration factor (range 0.1–10.0) |
| resolution |
INT |
128 |
Downsampling resolution for mesh generation (32–512) |
| make_solid |
BOOLEAN |
False |
When enabled adds a flat base and side walls to close the mesh |
Limitations
- Resolution is applied by uniform subsampling; fine features smaller than one mesh step may be lost.
- Non-square pixels emit a warning and the 3D surface represents physical scan area, not pixel grid.
- Very high resolution values (close to 512) with large fields may be slow to render.
