No color, no problem, with point cloud ambient shading!

 

From time to time, you get a point cloud file from a third party that has no color and no greyscale. 3D points are good but not necessarily easy to make sense of when there is no color or intensity depths to it. It may just come as a big flat monotone blob that you can’t comprehend. Luckily, TBC has the right tool for the job!

 

Monochrome point cloud without ambient shading

 

No more, thanks to the [Ambient Shading] rendering option in TBC. This will bring shades of depth to your point cloud, whether or not it is colorized.

 

Go to the [Point Clouds] ribbon tab, and click the little sphere icon dropdown in the [Rendering] group. The [Ambient Shading] will give your point cloud a whole new dimension, turning it from a flat meaningless blob to an actual comprehensible 3D scene. (Check out the teaser of the new look and organization in TBC v5.0!)

'Tis the season for TBC and Autodesk (specifically Civil 3D) interoperability. Join our October TBC Power Hour to learn how the two software packages work together for you. Feature coding, attributes, and drafting will be covered. Sign up here for the live October 31st session. If you can't make it, still sign up, you'll get recording notifications and you'll be able to watch on-demand for free!

Come one, come all! Tip of the Week time is upon us. This weeks Tip is on a little known selection method that is shared with Trimble Realworks, the Freehand (or Lasso) Select!

 

We all know of the Rectangle Select, perhaps also the Polygon Select, they have their own icons in the quick access toolbar and keyboard shortcuts after all. This week’s tip sheds some light on a selection method users have a love/hate relationship with, the Freehand Select!

 

To use the Freehand Select, begin by choosing Polygon Select from the Quick Access Toolbar.

 

Once in Polygon Select mode, the Freehand Select can be started in 3 easy steps:

  1. Click and hold the left mouse button then press and hold the Alt key.
  2. Move the cursor slightly.
  3. Release the left mouse button then release the Alt key.

 

Again, those steps are:

Left click and hold, Press Alt and hold.

 

Move the cursor slightly, release the left mouse button, release the alt key.

And voila! Freehand selection.

 

Now you can move your mouse and draw a line with which to select objects in Plan View or 3D View. When you are done drawing a selection area, double click to make the selection, just like with Polygon Select.

 

Again just like Polygon Select, drawing the selection clockwise will select only objects completely contained in the selection, and drawing counter-clockwise will select all objects which are partially contained in the selection area.

 

By doing this I have easily cropped this tree from the point cloud! I have the point cloud colored by elevation here.
