一个基于openVR的开源项目

openvr_survivor

About

This is an open source project based on steamVR development driver, used in the windows platform, can provide you with the following functions:

If you’re a regular gamer, you can experience all the SteamVR games on the keyboard as long as you have a set of PC and use compiled files.

If you’re a hardware driver developer, you can customize your HMD, handle controllers, and other peripherals based on this, so that they can be used on the steam platform, and you can refer to the already tuned virtual device, driver.

If you’re an application developer, you can debug your application based on analog devices and troubleshoot hardware devices.

If you’re already an experienced developer and passionate about VR, we want to be able to work together on some of the more interesting things, such as distortion, ATW, TW, tracking, prediction, and so forth. Join us.

SteamVR game example:

How to use

Use CMake to build visual studio project, and then open the “openvr_survivor.sln”, compiled the driver file package openvr_survivor, and then copy it to the “Steam\steamapps\common\SteamVR\drivers” directory, and then modify the default.vrsettings:

/**
file under the path:openvr_survivor\resources\settings
set your monitor resolution.
*/
"windowWidth" : 1920,
"windowHeight" : 1080,
"renderWidth" : 1920,
"renderHeight" : 1080,

Third party dependency Library

glog:log system, in order to better use, in the source code on the basis of some changes made.

glm:used to handle four element transformations.

hidapi:HID data interaction.

openvr:openVR interface.

doxygen:for document.

Development plan

optimization hand controller control.

Fix the handle shake while moving

Protect critical resources,e.g.HMD’s pose and handle controllers’ pose.

Add distortion function.

Added direct rendering support.

Problem fixing and improvement.

This is a preliminary version, relying on personal strength is difficult to perfect, if you have any good suggestions ,you can post in gitter chat room,and if you would like to join us, please contact me, my mailbox:helenhololens@gmail.com.
