Render 360 images with OSPRay and display them in VR

module_openvr

A OpenVR module for OSPRay and HTC Vive, currently just a 360 image viewer app. Uses OSPRay to render panoramic 360 images and displays them in VR.

Building

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

cd $OSPRAY/modules
git clone [email protected]:ospray/module_openvr.git

Then cd back to your OSPRay build directory and run CMake with the module enabled via -DOSPRAY_MODULE_OPENVR=ON. The GLM and SDL2 libraries are required to build the module and the OpenVR SDK is required for VR support. 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_OPENVR=ON \
	-DGLM_DIR=<..> -DSDL2_DIR=<..> -DOPENVR_DIR=<..>

If you don't have the OpenVR SDK on your system or don't specify OPENVR_DIR the app will build to just show the desktop mirror view with a fixed viewpoint.

Running

The module currently only contains the osp360 app which will use OSPRay to render a panoramic 360 image of a loaded model and then display this in VR as an environmeny map, allowing you to look around. To run pass the model to be loaded:

./osp360 <path to model>

Note: Currently the camera position is hard-coded for the Crytek Sponza model from the OSPRay demos page.
