Wikitude Support
Hi there,
Unfortunately I do not understand what your issue exactly is. Could you please provide more details regarding your use case and what is your problem?
Thanks,
Eva
Hi,
in cms panel or in wikitude studio i put the value for x and y like 20 or 7 or 16 but in sdk I have this value:
var overlayTwo = new AR.ImageDrawable(imgTwo, 0.5, {
offsetX: 0.12,
offsetY: -0.01
});
so I don't know to calculating the value offsetX and offsetY
up
Looks like there are different measuring units in Wikitude Studio and Wikitude SDK.
Wikitude SDK uses SDU units, and Wikitude Studio uses smth. else.
To be honest I don't know how to convert one to another.
Maybe Wikitude support office knows.
thanks I hope that Wikitude support office will answer me...

Hello,
Every content inside the AR View is specified in SDUs which relates to
the size of an object in the real world. Since objects further away
would be extremely small compared to near objects, objects are scaled
up. If you don't like the rate at which objects loose size with distance
from the user you can change the default settings with
AR.context.scene.* (see api reference for more details).
The
viewport of an HtmlDrawable is basically the size in pixel the html
content has available to be rendered. See this link and this article for more
details. Hope this helps.
If the goal is to have a physical size that is similar across all
screens, you can set the AR.scene.globalScale property to -1 which
enables auto scaling. There is no easy way to calculate how many pixel an object with a
certain size in SDUs will use. This depends on the viewing angle of the
camera, the distance of the object, screen resolution, ....
Thanks

ah ok I have understand but for convert to pixel in SDUs there is a formule?

Hi,
As stated above, there is no easy way to calculate how many pixel an object with a certain size in SDUs will use as this depends on many factors.
Thanks
