GFA visualizer, GPU-accelerated using Vulkan

gfaestus - Vulkan-accelerated GFA visualization

Demo: https://youtu.be/TOJZeeCqatk

gfaestus is a tool for visualizing and interacting with genome graphs in the GFA format.

It can display GFA graphs using a provided 2D layout (produced with odgi's layout command), and is intended to deliver an interactive visual interface for exploring genome graphs that is fast, powerful, and easy to use.

In addition to the 2D layout, a handlegraph representation of the GFA is created, which will enable visualizations and interactivity that take advantage of the graph topology, paths, and more.

gfaestus uses Vulkan for hardware-acceleration, via the ash crate.

Requirements

Compiling gfaestus requires the Vulkan SDK, available here: https://vulkan.lunarg.com/sdk/home

To run gfaestus, you must have a GPU with drivers that support

Vulkan. If you're on Windows or Linux, and have an AMD, Nvidia, or integrated Intel GPU, you should be good to go.

If you're on Mac, you'll need to install MoltenVK.
