I’ve been testing things, and been experiencing both success and oddness. I am running into a few issues, and I wonder if I could get some clarification to help me design …
** How does World Tracking stick your assets to the ground and keep track of where you are in relation to it?
-Does it take a picture of the ground and use that as a reference?
-Does it use GPS to determine where you are?
-Does it use the accelerometer to determine where you are based on speed and direction of your movement relative to where it thinks you place the assets?
**What’s the best practice for placing an object on the ground?
-Is a gridded surface most likely to give the best result, like a tiled floor?
-If you are in the park and the grass is a little bumpy, is this going to create a problem with world tracking and keeping your assets stable and in place?
-Should I be looking for instances of floor meeting walls at right angles - does that help determine what is flat?
**I’m reading about “anchors” in the documentation. It seems to suggest that we can place custom anchors to help keep a world tracking experience more stable. Is there more information about this that I missed? There was no link from that article to info about creating custom anchors, and a search of the documentation didn’t bring it up.
Here’s a bit of Info about my tests. Some things I’ve done so far…
I made an easy plane based chalk drawing of the Chartres Cathedral’s floor labyrinth pattern, and sized it quite large … perhaps 20m x 20m. I took it to the park and walked through it on the grass. It seemed fairly stable, though I didn’t walk it’s full path.
I tweaked the hallway maze I had made earlier when World tracking was dangled temptingly in front of us before it was implemented. And it seemed to work nicely with world tracking in my home. It’s difficiult to test things this large inside, and I tried in my driveway with some success. I couldn’t tell if it was moving oddly as I moved, but there were times when I suspected it wasn’t exactly where it should have been.
I put together a set of gothic hall pieces to make something quite large and mazey. So far, I have a hall that turns, and decided to test it outside tonight. It’s a bit late, and dark out there. I thought I might be able to get some streelight illumination on my street or in the park to get started to lay down the assets to the ground properly. But I ran into problems with the model not staying properly in place after it had locked to the ground. At times, it moved away from me as I walked towards it, and I expect this to be because of poor lighting conditions.
