Server Example: Ray Casting

Overview

Casts a ray from a fixed origin and visualizes the hit point with a polyline and a sphere. Use it as the simplest reference for ray casting; see Ray Test.

Target

CMake target: ray_casting.

Run

Run the build-tree executable:

./build-examples/examples/ray_casting

On Windows, run ray_casting.exe instead. This example uses RaisimServer. Start rayrai_tcp_viewer and connect to port 8080.

Details

  • Casts a single ray from a fixed origin every step; the ray direction sweeps around the vertical so the hit point traces a spiral.

  • Visualizes the hit point with a polyline and marker sphere.

  • Uses World::rayTest against terrain and primitives.
