Splat Surface Rendering

You can use this material to represent point clouds as closed surfaces.

How to Assign Material

  • Create a Splat Surface Rendering material
  • Select a point cloud
  • Go to the Rendering Options group in the Object Inspector
  • Select the created material from the Material drop-down menu
TIP: Details on creating new materials can be found here.

Material Settings

You can edit settings either in the Material Editor or the Rendering Options group of the Object Inspector.

  • Enable Object color to display a point cloud in one color. Use the color dialog on the right side to choose a color.
  • The size parameter controls the “closeness” of the surface. Make the Size so big that the surface is just closed, not bigger.
  • Turn on Has normals to activate normal vectors.
  • Back-face culling and Averaging are reserved for future use.
  • Enable Smoothing to improve visual quality, but this may decrease performance.
TIP: We recommend to start with a small smoothness value, and marginally increase it until the desired smoothness is achieved. An overly large smoothness value will blend colors with the background.

How to Show a Model Shaded

Similar to Point Cloud Rendering, you can display models shaded as follows:

  1. Select the point cloud of interest.
  2. Make sure that normals have been computed.
  3. Assign a Splat Surface Rendering material to your point cloud.
  4. Turn on lighting on the Viewbar.
  5. Enable Object color and Has normals in the material settings. Has normals will be highlighted in red if normal vectors are not available.
  6. Lastly, select the default Flashlight in the Object List, and increase its range and spot angle in the Object Inspector.
