I am working on a CZML code to display some models that represent historical data, but I’ve run into the following situation:
- The models tend to “wander” about their assigned coordinates as I adjust my view instead of the model’s origin being “pinned” to their coordinates. As I rotate the image, the model’s volume appears to continually center itself between my eye and the coordinates.
When using a billboard, we can assign the horizontalOrigin and verticalOrigin, which seems to keep the billboard “pinned.” Other geometries (point, ellipse, etc) don’t display this same behavior.
Is there a way, in CZML, to tame these unruly models? Any other thoughts?
NOTE - You can see this (unfinished) project at www.geo-animate.com/Commonweath-War-Graves. I have in total 120,000 spanning the five years, and I’d like to replace the points that you see with models that have a different behavior. Then I want to move the KML project on www.geo-animate.com/War-of-Movement to Cesium as well, but as this is all new to me I’ll need a bit of time.
