point_cloud_demo — 3D Point Cloud Visualization

Demonstrates how to visualize dynamic data structures in the CANape 3D scene window. Simulates a 3D point cloud with simple physics — bouncing points inside a boundary box — and measures the entire array of point structs as an XCP measurement variable.

What it demonstrates

Feature How it is demonstrated
Array-of-struct measurement std::array<PointT, N> measured as a typed array
Calibration parameters ParametersT — max points, boundary size, velocity, radius tunable at runtime
3D scene visualization CANape 3D scene window displays the live point cloud
C++ API CalSeg<ParametersT>, DaqCreateEvent, DaqRegisterMember

Files

File Purpose
src/main.cpp Point cloud simulation — physics, XCP server setup, event loop
CANape/ CANape project with 3D scene window pre-configured

Building

./build.sh examples
./build/point_cloud_demo

Or with CMake directly:

cmake -B build -S . -DXCPLITE_BUILD_EXAMPLES=ON -DCMAKE_BUILD_TYPE=Debug
cmake --build build --target point_cloud_demo
./build/point_cloud_demo

CANape

Open CANape/CANape.ini in CANape. The project is pre-configured for XCP on TCP, port 5555, with automatic A2L upload and a 3D scene window for the point cloud visualization.

If CANape cannot connect, verify the IP address in Device Configuration / Devices / XCP / Protocol / Transport Layer.
