Best Practices for Real-Time Rendering

Manage world coordinates

Georeferenced point clouds with large coordinates can easily challenge GPUs and cause precision artifacts. Those point clouds look rasterized or grid-like. When opening a point cloud for the first time, select Origin from the Offset type dropdown menu in the Octree Options dialogue to prevent these issues.

Beware of the quality & performance tradeoff

Increasing the GPU cache and decreasing the Minimum coverage under Edit > Preferences will boost the number of points rendered and thereby improve the render quality. Beware, this might slow down the rendering.

Choose the right material settings

When opening a point cloud, a new Splat Surface material is created and assigned to the point cloud. For a closed appearance, make sure to select the point cloud and adjust the Size parameter under Object Inspector > Material Attributes.

If your point cloud does not contain RGB color information, select a suitable display mode (Object color, Elevation, or Intensity).

To choose the Intensity display mode, verify that your point cloud contains intensity information under Object Inspector > Object Attributes.

For the Shaded option to work, normals must be available. When opening a point cloud for the first time, normal computation is enabled by default. Under Object Inspector > Object Attributes, you can verify the availability of normals.
