Is there a way to disable sizeAttenuation for an Object3D in THREE.js?
I'm working on rendering a trajectory at a massive scale using arrow helpers to show the motion direction. I want the arrow heads to maintain their orientation without changing size when zooming the camera (unlike with sprite points in a pointcloud). Are there any alternative approaches that can achieve the same effect, such as using point clouds or lines?
Adjusting the sizeAttenuation of a sprite can create an illusion of virtual size by rescaling its position in relation to the camera. This is particularly useful when dealing with Object3D's that have an inherent scale based on perspective.
If switching to an Orthographic Camera isn't feasible for your project, consider these alternatives:
