Overview

Vyzn was created to assist people in turning a 3D model, whether it is a building, consumer or industrial product, or any other object, into an augmented reality presentation and experience it with other people without writing a single line of code.

Required Skills

You need basic skills with a 3D editor supporting 3D object hierarchy and FBX export. Maya, 3ds Max, Cinema 4D, Modo, and Blender (which is free) are just some among many.

To use advanced features like timeline and subtitles you need to be slightly familiar with Unity. No coding is required even in this case.

Adding Vyzn Features

To add a view, a spot, a movable object or any other feature listed in the table of contents to the left, open your model in a 3D editor of your choice (it must support 3D object hierarchy and FBX export), then add the "Model" root element and move all 3D objects representing your model there. Then follow documentation to add specific features.

Required Software

Vyzn is a HoloLens app, plus some WEB interfaces and cloud infrastructure. We don't provide a 3D editor to author presentations. Instead, you should use any 3D editor that supports 3D object hierarchy and FBX export. You can use 3ds Max, Maya, Cinema 4D, Modo, Blender (which is free) or any other editor of your choice.

SketchUp doesn't support 3D object hierarchy, so if you want to create a presentation with Vyzn features based on a SketchUp model, then you should export the model and work with it in a different 3D editor. Please check our video tutorial on how to do that.

Vyzn Presentation Preparation Pipeline

  1. Ensure that your presentation is in line with the optimization guidelines.
  2. For all objects having more than one material, bake materials into a single texture atlas and replace all the materials with one that uses the resulting texture, so that no more than one material is used per object (UV maps should be non-overlapping).
  3. Add desired Vyzn features using a 3D editor of your choice (it must support 3D object hierarchy and FBX export).
  4. Export your presentation as an FBX file, ensuring that it is in line with the requirements.
  5. Upload the FBX file into Vyzn to generate a unique address for your presentation.
  6. Press "Start Session".
  7. Launch Vyzn on all HoloLens devices you want to use and look at the code to scan it.

Creating a Presentation from a Revit Model

To see your Revit model in Vyzn, you will need to export its shape to FBX format:

  1. Switch to the 3D view mode.
  2. Adjust viewport to select what part of the model will be exported.
  3. Use Visibility\Graphic menu on the View tab to hide unnecessary components.
  4. Select lowest detail level among coarse, medium, and fine to minimize number of polygons in the scene.
  5. Export your presentation as an FBX file.
  6. Open the FBX file in any 3D editor of your choice supporting 3D hierarchy and FBX export.
  7. In order to avoid issues with native Autodesk materials, bake materials into a single texture atlas and replace all the materials with only one using the resulting texture so that no more than one material is used per object (UV maps should be non-overlapping).
  8. Optimize the scene per the optimization guidelines.
  9. Add desired Vyzn features.
  10. Export your presentation as an FBX file, ensuring that it is in line with the requirements.
  11. Upload the FBX file into Vyzn to generate a unique address for your presentation.
  12. Press "Start Session".
  13. Launch Vyzn on all HoloLens devices you want to use and look at the code to scan it.

If you have a simple model (with low polygon count), you can skip points 5 and 6. The FBX shall be visible inside Vyzn, however it may have some artefacts or low FPS rate.

You can download the demo FBX and use it as a reference.
