I had big plans to show some cool things this week. Unfortunately, things didn’t go too smoothly for me so I decided to try and see what a post processing effect would look like on the HoloLens. The results on the video look pretty cool, but in person it wasn’t that great.

It is to be expected as the ripple effect I created is only visible in the field of view and in this type of effect it really breaks the flow. So I couldn’t suggest anyone try to do a post processing effect in the HoloLens itself. (Not that I would expect many people to try…)

If time allows, and I have better success than I did today, then I may try to take that effect and have it run against the different planes in the room. So it will look like the walls have the effect.

Enjoy the video!

I brought out the demo I was working with last week and changed the material to use an occlusion material (basically all black) for the spatial mapping object. So when I say “Show” (and when the demo starts) the blue wireframe material is being used. But when I say “Hide”, the material on the spatial mapping object is switched out to the occlusion material.

I added in a smaller ball projectile that I can instantiate / spawn by saying “Shoot”. I have high bouncy effects associated to both the original larger ball and the smaller projectile balls. They all have a rigid body so that physics work correctly between each other and the spatial mapping of the environment.

This took very little code and very little effort, but I’m happy with the results so far. I’ve had a request to create a tutorial around the spatial mapping and how I got working so I’ll work on creating a detailed video and/or post about that soon.

If you like the demo and want to see more please let me know. There are so many things I can spend my time on and I only want to share this stuff if it is actually beneficial to others. So if you like it and want more, let me know in the comments (or by subscribing or leaving a comment on YouTube).

Enjoy!

A few weeks ago I created a simple demo of a bouncing holographic ball. I’ve extended the demo to actually take into account the geometry of the room that the HoloLens provides in the form of spatial mapping.

In the demo video below you will the ball bouncing off of the different objects in my basement. The spatial mapping geometry can be seen since I used a blue wireframe material. While the mesh is visible, the ball is hidden when it is behind an object like a couch. It isn’t hidden from view when I hide the spatial mapping data. Once that is hidden, you can see the ball through the couch. I’ll be tackling that at some point in the near future.

If you have anything you want to see let me know. If you want me to create a tutorial on how to do spatial mapping on the HoloLens leave me a comment and let me know. If there is enough interest, I’ll spend some time creating a step by step tutorial.

Enjoy the video!

I wanted to bring you a quick video this week to show off three new apps in the app store. My favorite of the three is HoloBlocks. The spatial mapping is done really well. Next week, I’ll talk a little bit about spatial mapping with actual tutorials that will follow about how to do your own room scan and how you can utilize the spatial mapping information in your own apps and games.

Enjoy the video!
