CPP Samples

The CPP Samples demo showcases the use of engine features for various use cases via the C++ API.

The Landscape Terrain sample set demonstrates various Landscape Terrain features and use cases:

  • Combined Landscape Modification sample — combination of nondestructive (using multiple Landscape Layer Maps) and destructive (using Landscape::asyncTextureDraw) Landscape Terrain modification techniques.
  • Landscape Creation sample — dynamic creation of a Landscape Layer Map with albedo, height, and two mask textures using LandscapeMapFileCreator and LandscapeMapFileSettings.
  • Details sample demonstrates how to add Details to a Landscape Terrain using ObjectLandscapeTerrain::getDetailMask and ObjectLandscapeTerrain::addDetail methods.
  • Excavation sample demonstrates how to perform destructive Landscape Terrain modification at run time using the tractor grader. This modification is by changing the underlying textures of Landscape Layer Map.
  • Fetch sample shows how to get terrain information (height, albedo, masks) for an arbitrary point.
  • Landscape Mesh sample demonstrates the generation of a mesh (ObjectMeshDynamic) representing a certain region of the Landscape Terrain based on fetched Landscape data (LandscapeFetch).
  • Paint sample demonstrates destructive run-time Landscape Terrain modification by changing the underlying textures of the Landscape Layer Map using Landscape::asyncTextureDraw with the help of the custom base materials.
  • Tracker sample demonstrates how to animate objects (change their position, rotation, and scale) via tracks created in the Tracker tool. Tracks in code are referred to via names and IDs. The TrackPlayback component uses a C++ wrapper for Tracker functionality implemented in the Tracker component.
  • Tracks sample demonstrates non-destructive runtime Landscape Terrain modification by spawning multiple Landscape Layer Maps under the objects to create tracks.
  • Water Global samples demonstrate how to control Global Water via API:

    • Buoyancy sample shows how to control the current state of Global Water via changing Beaufort levels (the Beaufort slider). It also demonstrates the use of fetching of the water level at a certain point for simplified simulation of buoyancy without engaging Physics.
    • CustomWave sample shows how to control the wave spectrum of Global Water in Manual mode via API by changing the number of octaves, number of waves per octave, and various other parameters for random waves generation, such as wave length, amplitude, phase offset, and steepness (can be used, for example, to process Weather Control packets from IOS in a simulator application).
    • Boat sample demonstrates how to simulate ship wake foam via Orthographic Decals and Particle Systems, that are spawned behind the boat and project foam onto the water surface. You can control sea state via the Beaufort slider (from 0 - calm to 8 - huge waves).
