HTC Vive Setup

Author:
Please note that this is a BETA version of the document. All information presented is correct but we are working on improving the details.

Note that this documentation only provides a help for performing your own experiments with HTC Vive. Aximmetry does not officially support using HTC Vive as a camera tracking system. We strive to create the means for your experiments in Aximmetry, but we cannot provide any support for these and we cannot guarantee any result.

This documentation assumes that you are already familiar with how to add and handle Unreal scenes to your Aximmetry compound. If not please see these: Getting started with The Unreal Engine based DE edition and How to install and work with the Unreal Engine base DE edition.

Setting up Vive with SteamVR

First, install SteamVR with Steam store.

Once SteamVR is running and has the hardware turned on and paired, then paired hardware should be visible as blue items.

Tracker:   Base station:  Head Mounted Device (HMD):

Next, the area of the room has to be defined and the devices calibrated. Access the Room Setup option by clicking on the button at the top left corner.

Depending on the setup, Standing Only option can be enough.

Once devices are paired and calibrated with SteamVR, Aximmetry does not need a running SteamVR to get the tracking data.
However, the Head Mounter Device (HDM) has to be physically connected all the time even if it is not used.

Base Station version 1.0 and Base Station version 2.0 can not be used together.

Setting up the compound, camera input, and keying

If using Unreal for Aximmetry follow this (DE) Camera Tracking documentation to set up the compound. And then follow this (SE) documentation to set up input, keying, and studio.

If using Aximmetry, just follow this (SE) documentation to set up input, keying, and studio.

Adding HTC Vive tracking

Switch to Studio mode in order to easily see any camera movements.

At this point, you already have some tracking. If you move your Vive tracker the virtual camera will move according to it.

Please make sure that your Vive system is properly calibrated so that the origin is on the floor.

Calibrating tracker and lens

Please follow this documentation.
