Claim One:
1. A computer-implemented method for generating a virtual terrain, comprising: receiving one or more assets specifying characteristics of a terrain; adding each of the one or more assets to at least one layer, wherein each layer is configured to store geological features as a displacement field, wherein the virtual terrain is generated using overlapping displacement fields representing geological features from respective layers, and wherein the layers are overlaid on top of each other; receiving one or more edits to the virtual terrain, wherein the one or more edits are made to create peaks, create or trace ridges, synthesize terrain texture, and/or copy and paste geological features; adding each of the one or more edits to a respective layer; and blending the displacement fields representing the geological features stored in the layers using a frequency-aware layer blending technique to generate the virtual terrain, wherein the frequency-aware layer blending technique is a Laplacian blending technique applied to blend the displacement fields representing the geological features stored in the layers based on at least one or more user-specified strengths of frequency band contributions within the layers.
