Morphing Terrains

You can modify a terrain locally. The portion of terrain locally modified passes through one or several points or curves.

  1. From the Prepare section of the action bar, click Morph Terrain .
  2. Select one terrain to deform.
  3. Select the Target Elements (points, or curves, or clouds of points).

    Notes:
    • The Target Elements can be one or several points, or curves, or clouds of points through which the output terrain passes.
    • A target cloud of points must contain only a moderate number of points.
    • The Projection Type is Direction, and Z Component).
    • The projection of the target element according to the projection type below must lie completely inside the Limit Element, if any (or its projection on the terrain).

  4. Select a curve or a join of curves as the Limit Element.
  5. Select a type of Constraint Attenuation to control the shape of the terrain morphing.
  6. Optional: Select the Insert Target check box to project the target elements projected on the terrain to deform.

    Note: If you select this option, no color is specified on new points.

    The projected points are inserted in the terrain to deform.
  7. Optional: Select the Insert Limit check box to project the limit element on the terrain to deform.

    Note: If you select this option, no color is specified on new points.

    The projected points are inserted in the mesh to deform.
  8. Optional: Modify the Projection Type.

    Tip: Right-click Direction to create required elements.

  9. Click Apply.
    • The Target Elements (one or several points or a curve) are projected into the terrain to deform according to the specified direction. This projection acts as a handle.
    • Then the terrain is deformed within the limit element as if you were dragging that handle to the target elements.
    • Tangent continuity is ensured between the deformed terrain and the non-deformed terrain lies outside the limit element.

A MeshMorphing.x feature is created.
