Getting things working

There are two things you should consider doing to your system before running libsurvive.

(1) Install the udev rules: cp usefulfiles/81-vive.rules to /etc/udev/rules.d/ and reboot. (2) If you are running on an NVIDIA Card, you will need to AllowHMD to true. Add the following line to your /etc/X11/xorg.conf device section: Option "AllowHMD" "yes"

Introduction

High-performance HTC Vive Library

I say "high-performance" really this project is based tightly off of OSVR-Vive-Libre, but, specifically is an attempt to:

1. Minimize external libraries. Actual reason for starting this: Downloading all of the libraries needed for OSVR-Vive-Libre maxed out my data plan.
2. Put it under an open-source instead of a force-source license. (GPL to MIT/X11)
3. Write it in C.
4. Avoid extra layers where convenient.
5. (long shot) Make the vive vivable for use with Intel Integrated Graphics systems.

Will I we succeed? Probably not.

Definitely going to try!

External dependencies

• libUSB
• pthread
• libX11 (where applicable)
• zlib (may use puff.c if needed)

If I ever get to video output... OpenGL.

Architecture

There is an internal representation and an external representation. These lines may get blurred. Internal representation lives in .h files in the src/ folder. External lives in include/ folder.

It is written in some fairly stout "layers" which are basically just function calls:

I may or may not read data from the Vive regarding configuration. If I do, it would be added to the survive_usb.c
