Terrain Add Contour

Where can I find this command?

This command adds a new elevation data to an existing terrain. This input data can be 3D curves, contour lines and point clouds.

Add Contour

Steps:

  1. Pick a terrain. Press Enter or right-click when done.
  2. Select the new terrain Elevaton Data (3D curves, contour lines or points) to add to the terrain.
  3. The selected input will be added to the existing terrain data, and the terrain will be recalculated with the new information.

Control points

The control points for Elevation data are the same as those of the curves or points used in this operation. Additionally, a move control arrow is provided to reposition each of these inputs.

These control points are integrated with the terrain and are visible when the terrain's control points are enabled.

Control points can be disabled in the Elevation data tab,in the Properties area of the Edit panel, after selecting the Elevation data from the selection list.

Options and Parameters

The Elevation data parameters can be edited from the Elevation data tab in the Properties area of the Edit panel, once selected under the Elevation data list.
For the Elevation data to appear in the selection list, the terrain must first be selected from the viewport.

Elevation data
Elevation data tab in Properties area.
  • Name
    Rename the input.
  • Show grip points
    Enable or disable the control points for the input data.
  • Sampling
    Controls how data points are selected or extracted from the inputs to define the terrain. It influences the accuracy and spacing of the points used in the triangulation process but doesn't directly affect the overall detail of the resulting mesh.
    • Max sample interval
      Define the maximum distance between sampled points along the input curve. A smaller interval increases accuracy but may create a more complex terrain mesh.
    • Max deviation
      Specifies the maximum allowed deviation between the input curve and the simplified version used for terrain generation. Lower values preserve more detail, while higher values allow more simplification.
Note

The parameters can be edited for each input that defines the terrain. If you select the Elevation Data node from the selection list instead of a specific Input, the modified parameter will be overwritten for all inputs.

Edit options

These are the available edit options for each of the input listed, accessible in the Edit area of the Edit panel:
