liteviz: A Lightweight Visualizer for Real-Time 3D Application

liteviz is a lightweight 3D real-time visualization application designed for common 3D vision-related tasks, such as SLAM and 3D real-time reconstruction. It supports visualization of common 3D elements and is both lightweight and extensible, allowing integration into your application with just a few files. Custom shader support provides greater extensibility compared to Pangolin and Open3D. Compatible with C++ projects and easily wrapped for Python applications.

Build Instructions

Prerequisites

C++17 or later

CMake 3.14+

Build & Running

# build the examples/cube
git clone https://github.com/panxkun/liteviz.git
cd liteviz
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release -DBUILD_EXAMPLES=ON && make

./examples/cube/cube-test

Then you will see a cube with mouse interaction.

How to Use in Your Project

Follow the use in examples/cube/main.cpp for a quick start. You only need to include the liteviz folder in your project. Then

#include <liteviz/core/detail.h>

using namespace liteviz;


class YourConfig : public LiteVizConfig {
    // Your code here
};

class YourRenderer : public LiteVizRenderer {
    // Your code here
};

class YourVizApp : public LiteVizApp {
    // Your code here

    // register your renderers here
    bool initResources() override {

        std::shared_ptr<YourConfig> config = std::make_shared<YourConfig>();
        std::shared_ptr<YourRenderer> renderer = std::make_shared<YourRenderer>(config.get());
        this->_registeredRenderers.push_back(renderer);

        return true;
    }
};

Then your can use YourVizApp to start your visualization application.
