* Add a point cloud example that changes the point orientation Note that it is really difficult to see what is going on without a texture, so added a texture to this exmaple as well. * Apply suggestions from code review Co-authored-by: Alexander Bock <alexander.bock@liu.se> * Update example identifier to be unique --------- Co-authored-by: Alexander Bock <alexander.bock@liu.se>

-- Orientation - Face Camera Position
|
|
-- This example creates a point cloud where the planes that make up the points are
|
|
-- oriented to face the camera position, rather than the view direction (which is
|
|
-- default). This means that the point will be layed out in a spherical way around the
|
|
-- camera, which works better for spherical displays compared to the default
|
|
-- orientation.
|
|
--
|
|
-- A texture is added so that we can more easily see how the orientation is altered.
|
|
-- See Textured example for more details.
