OSPRay + Vive

A sample OBJ viewer for OSPRay using OpenVR SDK to work with the HTC Vive.

Building

First clone the module into OSPRay's modules/ directory.

cd $OSPRAY/modules
git [email protected]:Twinklebear/ospray-vive.git

Then cd back to your OSPRay build directory and run CMake with the module enabled via -DOSPRAY_MODULE_VIVE=ON. SDL2 and the OpenVR SDK are required to build. If these libraries are installed in non-standard locations (or you're on Windows) you can specify the root directories of each library when running CMake. For example:

cmake <other OSPRay params> \
	-DOSPRAY_MODULE_VIVE=ON \
	-DSDL2_DIR=<..> -DOPENVR_DIR=<..>

Vive Module

The Vive module defines additional VR specific types for OSPRay such as the VR Camera and (in the future) other types for foveated or distorted rendering and so on.

Vive Sample App

The ospray-vive app uses the module and the OpenVR SDK to render to the HMD. This app is a simple OBJ viewer which uses tinyobjloader to load OBJ files and renders them using the raycast_Ns renderer to render them. For example:

./ospray-vive <path to model>
