Detailed Description

External tooling.

The programs in this directory are external tools used to inspect and interact with the main engine process. They share some code with it, but are executed as separate processes and communicate via pipes and the engine's Lua socket.

See the screenshots page for some examples:

Most tools have corresponding directories under src/lua and src/lua/lib. Both are libraries used to launch the tool from within the engine, the former offers a more convenient interface which performs common tasks for interactive sessions.

Tools can be divided into input and output. Input tools are:

• launcher is a small window with several buttons that can be used to quickly start other tools with preset configurations. It can persist across engine invocations.
• configure: a generic configuration dialog with support for boolean, integer, floating-point, and text values.
• camera_server: a web server which receives orientation data from a (possibly external) device (optionally via Javascript using its simple web interface) and translates it into camera orientation commands. See https://bbguimaraes.com/nngn/screenshots/engine.html#videos.

Output tools are:

• inspect is a simple text field which can display textual data, such as the text dump of the texture cache.
• plot displays conventional line graphs, such as memory usage and camera parameters.
• timeline displays line graphs as segments of a fixed time period, used to display various types of profiling information.
