[x3d-public] [x3dom-users] PointProperties in X_ITE

[Don Brutzman]

Thanks for looking at this example, which was one of three that needed a
little updating.

   - X3D Example Archives: Basic, Points
   - This directory demonstrates point-based rendering using PointSet and
   PointProperties. Such techniques are an important option for rendering
   scans and point clouds.
   - https://www.web3d.org/x3d/content/examples/Basic/Points/

It is not clear that PointProperties is well supported by many browsers.

Nevertheless PointProperties does have excellent support, as the following
composite-screenshot image showing 9 separate players demonstrates.

   - X3D Example Archives: Basic, Points, Archimedes Point Properties
   - PointSet rendering of 3D scan with color applied per vertex,
   renderable with PointProperties settings
   -

   - ArchimedesPointProperties X3d Players Comparison
   -

Author Vince Marchetti also provided the following interesting example,
which emulates a spherical shape for points as sprites, using a 2D image
showing a simple rendered sphere.  Cool hack!

   - X3D Example Archives: Basic, Points, Basic Point Sprites
   - PointProperties test case emulating spherical point sprites by
   displaying colored images of spheres. This model is suitable for X3Dv4
   implementation comparisons and conformance.

It is easy to think of a few more examples that might be added...
especially perhaps showing PointProperties effect present versus
missing, side by side.  Contributions welcome.

all the best, Don
