Disk

public Disk()

Disk

public Disk(String name,
 int shellSamples,
 int radialSamples,
 double radius)

Creates a flat disk (circle) at the origin flat along the Z. Usually, a higher sample number creates a better looking cylinder, but at the cost of more vertex information.

Parameters:

name - The name of the disk.

shellSamples - The number of shell samples.

radialSamples - The number of radial samples.

radius - The radius of the disk.

Disk

public Disk(String name,
 int shellSamples,
 int radialSamples,
 double radius,
 double innerRadius)

Creates a flat disk (circle) at the origin flat along the Z. Usually, a higher sample number creates a better looking cylinder, but at the cost of more vertex information.

Parameters:

name - The name of the disk.

shellSamples - The number of shell samples.

radialSamples - The number of radial samples.

radius - The radius of the disk.

innerRadius - The inner radius of the disk. If greater than 0, the center of the disk has a hole of this size.
