Astrid

A relativistic ray tracing server and end-user application built on Astray.

Requirements

• CMake 3.23+
• Astray 1.0+

Installation

• Run bootstrap.[bat|sh]. This will install all dependencies except Astray, and create the project under the ./build directory.
• Run cmake on the ./build directory and point astray_DIR to the build directory of Astray.
• Configure, generate, build.

Tutorial

• Run astrid.exe.
• Click the File menu and select "Connect to Local". This will create and connect to a local Astrid rendering server.
• In the "Integration Parameters" toolbox, choose the "Schwarzschild" metric.
• Click the "Render" button on the bottom left.
• Adjust the parameters and repeat.

Interactive Rendering

• In the "Observer Parameters" toolbox, untoggle "Look at Origin". This will allow you to rotate using the mouse.
• Toggle the "Auto Render" on the bottom left.
• Use the keyboard (WASD) and the mouse to interactively browse the metric.

Notes

• The screen size has an effect on performance. More the pixels, slower the rendering.
