3D Navigation Tips

For complex subsea layouts where you have also have a lot of subsurface data 3D navigation can sometimes be a bit tricky when you try to zoom in on specific details of e.g. topside and subsea assets. If you experience that even with small mouse movements that you zoom by the asset you are probably experiencing difficulty with the system raycasting algorithm. This sends a ray ahead of your viewpoint and try to collide with what is in front of it to decide on the navigation control sensitivity. If there is maybe 1000 meters before it collides with something then the zoom factor will be large. To alleviate this we recommend trying to adjust the following settings:

• Water Opacity - If this is below 0.2 the navigation raycasting will ignore the current water level so if you try to view a topside asset we recommend that this is at least 0.2 or higher. 

• Layer Opacity - If you have e.g. a 3D Surface layer loaded (bathymetry/survey) and the layer opacity is set to less then 0.2 the navigation raycasting will ignore if you try to view subsea or subsurface assets. We recommend that the layer opacity is at least 0.2 or higher.
