Confusion with defining Cuboid targets

April 6, 2013 - 2:48am #1

Hi,

When defining a cuboid target, it would be great to better explain which axis are defined

by the width height and length dimensions. I assume the width is the size along the y-axis

height defines the z-axis and length the x-axis, but then again, I could be wrong...

Second, when viewing the resulted multitarget after uploading all the images, it seems

the left and right image are not mapped correctly with the 3D preview, it looks they are rotated

by 90 degrees. I use Safari as my browser.

Any insights ?

hello all,

 

as of june 2015 the bug with the 3d visualization of the cuboid in the target manager page has not been fixed. it will be nice if it gets fixed soon, given that at first causes confusion

Thanks Gideon for your comments!

We will take your suggestion into account for documentation improvement.

Confusion with defining Cuboid targets

Hi Alessandro,

Thanks for the fast reply ! I've read the documentation and was just confused by 

the different wording for the cuboid sizes. The documentation mentions width height and depth,

whereas the Target Manager uses Width, Height and Length . Might I suggest to use  consistent 

names for the various sizes, pref width height and depth in the target manager  (wink) ?

I have successfully made a cuboid which tracks very well.

BTW, am really impressed with the tracking speed and quality, thanks for the great library!

Hi,

the axis orientation are illustrated in this page of the developer guide (scroll down the page a bit and you'll find them):

https://developer.vuforia.com/resources/dev-guide/multi-targets

Concerning the left and right faces having wrong orientation, this is a known issue, we are working to fix it; note however, that when you export the Dataset, the left and right faces will have the correct orientation (so the issue that you observe is just a wrong 3D cuboid preview)
