2D Operator Terrain Network

Introduction

The HeightMap operator extracts a 2D heightmap from the terrain flow, converting 3D terrain data into a 2D representation. This is useful for exporting terrain elevations, performing downstream 2D processing, or integrating with external tools and workflows.

Parameters

• Resolution: Sets the output heightmap size (width x height).
• Source: Selects the terrain or network node to sample.
• Format: Specifies the output format (e.g., grayscale, float, image).
• Range: Defines the minimum and maximum elevation values to map.

Usage

Apply the HeightMap operator to generate a 2D elevation map from your terrain network. Adjust resolution and range to match your requirements. Export the resulting heightmap for use in other applications, or use it as input for further 2D operators and texture generation.
