Remix of great tool for visualization via TCP. Original Rewind Viewer writen by Vladimir Kiselev (aka kswaldemar) is located here.

Key differences with original rewind viewer:

• Binary protocol - for faster communication and more primitives per frame;
• Slaves client connections - can draw but can't finish frame;
• Camera views;
• More primitives and API methods;
• YAML configuration;
• UI updates;
• Updated 3rd party libs;
• Even more OpenGL optimizations
• Mouse and keyboard events
• Bugfixes.

Original features:

• All figures are drawn using your video adapter, so no more problems with slow drawing
• Rewinding - ability to navigate between game ticks
• In Pause navigation - zoom and navigate in any game state
• Handy mouse navigation

Drawbacks:

• Viewer running as standalone application, it knows nothing about your strategy, so you need manually send all data and you can draw only data visible by your strategy
• In theory, high memory usage, because it needs to store all drawing primitives for rewinding support

There is no binaries for now. You should build rewind-viewer yourself.

Clone repository with submodules:

git clone --recursive https://github.com/mortido/rewind-viewer.git
cd rewind-viewer

Linux:

# Install dependencies
sudo apt-get update && sudo apt-get install -y libglu1-mesa-dev libxrandr-dev libxinerama-dev libxcursor-dev libwayland-dev libxkbcommon-dev libxi-dev libgtk-3-dev

mkdir build
cmake -S . -B build -D CMAKE_BUILD_TYPE=Release
cmake --build build --target rewind-viewer -j

MacOS:

mkdir build
cmake -S . -B build -D CMAKE_BUILD_TYPE=Release
cmake --build build --target rewind-viewer -j

Windows:

mkdir build
cmake -S . -B build
cmake --build build --target rewind-viewer -j --config Release

Note: Compiler with c 17 support needed.

Run Rewind Viewer before starting you code. It will reset itself on new connection, so no restarts required.

See clients for more information regardless specific language usage.

• Generate flatbuffers messages for your language. See Makefile for more info. You will need FlatBuffers compiler (flatc) to be installed.

# Example of message generation for c  
make cpp_client

• Use message protocol and existent clients as guidelines
