Hello, Cesium followers.
I recently found that Polyline Arrows lay in a plane that is oriented to be orthogonal to a user’s direction of sight.
So when I try to draw it on the ground the look of a arrowhead is a little strange and it rotates with the camera (you can see it at the Geometry/Polylines sample at Sandcastle).
I’d like to make it look something like the right arrow on the following picture (I’m sorry for a poor drawing - tried to show an arrow that lays on the ground and doesn’t rotate with the camera)
I’m ready to make a new version of PolylineArrow material for my project and for the community. Just need a hint which part of the code is responsible for arrow plane orientation in the corresponding shader.
Can anybody help ?
Thank you in advance.
