Why We are Making this Project
This is a project used to demonstrate and learn how to use spatial computing in everyday applications. This project contains an evolving collection of objects that can be observed, extracted and placed using the Magic Leap One. makeSEA is the premier content management and delivery platform for Magic Leap. To learn more and become a beta user please Contact Us.

Topics Covered
This project focuses on content designed for delivery via the Helio browser using Prismatic scripting and markup.
Inputs
- ML Remote
- World Sensing
- Wold Mesh with Occlusion
Design Practices
- Headpose-based Object Placement
- Near Clip Plane Exploitation*
Presentation
- Helio Browser
- Casting
*considered a spatial computing no-no and reality-breaker but, useful for certain technical applications

try OOTB build first, if errors:
in order for this to build on mac with unity env the scripts with names including Test need to be moved under directory named "Editor":
move /Assets/Resources/*Test* /Assets/Editor
move /Assets/Unity/Scripts/Tests/*Test* /Assets/Unity/Scripts/Tests/Editor (dir should already exist()
notes:
(older; may be better options; was used for CAD from mfg I think)
dwg -> fusion360 import -> fxb -> gtlf

for STL:
(works but requires human):
STL->OBJ (meshconv) -> Unity -> light/textrure -> glTF -> glb (gltf-pipeline)
working (experimental):
use obj2gtlf to get direct from obj to glb with light/texture embedded (as .mtl); we are having issues getting good result on MLOne
alt attempt: try getting to fbx instead using Blender and command line w/script, ref:

Stove Appliance Notes
- Works well with photos even if the photos are a little bit blurry.
- Once the sparse point cloud is created, the next best thing to do is to change the bounding box to just your subject. In this case a stove. That way it will be able to still use the background noise to help create the dense point cloud, but all of the points outside of the bounding box will n
- 3DF Zephyr takes a long time to extract photos from the video.
- At 1 frame per second capture rate, the program was able to obtain 87 photos from the video that is 01:23 minutes long.
- Out of those 87 photos only BLANK were able to be used.
- I was able to increase this number to 70 by changing the sparse cloud from default to deep.
- Sparse point cloud and the dense point cloud created from just taking photos are a lot more detailed with less holes when creating the mesh
