I recently get my hand on an HTC Vive headset, and I spend some
time exploring various solutions to display a model in this
headset.

The HTC Vive headset

There are a handful of solutions, like the Revit
Live
from Autodesk or Enscape, but I choose to focus on
a VR-only solution build by IrisVR, Prospect.

Installing Prospect is pretty straightforward, and you end up
with the Prospect application along with the Revit plugin.

I run the Revit plugin, select a 3D view, and export my model
to the Prospect application.


Export your Revit model to a VR scene

The resulting virtual visit is saved in my Prospect library. I
can also save this scene as an external file, to open it in
another computer running Prospect and a Vive headset.

The visit itself is divided in two, a scale model overview and
a walkthrough.

In the scale model mode, you can see a small-scale view of the
model that you are able to manipulate like any 3D view in your
favorite design tool. You can also add sections and move them
around. The feeling is close to manipulating an actual physical
mockup, as we move it, turn it around and “grab” it to have a
closer look.

This scale model mode also works as the entry point to the
virtual visit itself, as it allows you to teleport yourself in
the building.

Teleport in the model

In the second mode, the visit itself, you can actually walk
into the building and look around. The navigation tool is well
designed, and you quickly end up teleporting yourself
everywhere in the building, walking around like you own the
place.

Along with the walkthrough, Prospect provide a few tools for
design review, like screenshots and markups. You can draw a few
notes in mid-air and take a picture of your annotations for
later review.

There is also a nice daylighting simulation tools which helps
us feel the light inside the future building.

To enjoy all these features, you will need a Pro subscription,
but you can start with the free tiers, which include the
ability to create a VR scene from Revit, Rhino and Sketchup.

The overall experience is really…
