/**
|
|
* Demo program rendering a 3D visualization of points distributed using the Hammersley sequence in 3D space.
|
|
*
|
|
* The application is set up at a resolution of 720x720 pixels. Within the visual
|
|
* program, a sphere mesh is created and a set of 1400 points is generated using
|
|
* the Hammersley sequence. Each point is translated and rendered as a small sphere
|
|
* in 3D space. This is achieved by mapping the generated points into a scaled domain.
|
|
*
|
|
* The rendering utilizes the Orbital extension, enabling an interactive 3D camera
|
|
* to navigate the scene. The visualization relies on the draw loop for continuous
|
|
* rendering of the points.
