3D lane
This geometry shape is drawn using the 3D lane tool. It is mainly used to mark road markings. What differentiate it from 3D linesο»Ώ is that you can adjust the line's width, in other words set the left and right boundaries.
We recommend using the Point slicingο»Ώ in tasks where vehicles on the road may obscure the points of interest on the ground.
Set width
- Select a class,
- Click at either the leftmost or rightmost edge of the line,
- A red indication should appear
- Click at the opposite edge
- This should create a lane marking shape
Place points
- Move along the lane markings and place points where you want to have control points.
- The points will be placed at the lowest point in the point cloud at that location.
- Continue placing points until you feel done with the object.
Use the 3D Transformation controlsο»Ώ to adjust the placement of the line point. To change the entire line, press shift before moving the controls. See Node and shape editο»Ώ and Multiple nodes editο»Ώ for more information.
You can extend a lane from the start or end with keyboard shortcuts. Press 0 to extend the line from the end or shift+0 to extend the lane from the beginning. Read more about an alternative way to extend the lane here.
Zoom to selected to quickly review the points along a line by pressing k.
Step between points using alt+nand alt+p.
You can reverse the line direction by clicking on the 3D lane with the right mouse button and selecting "Reverse direction." See Direction indicatorο»Ώ for how to view lane direction indicators.
No automation features are available for 3D lanes.
