Class CylinderTriangulator

java.lang.Object

agi.foundation.geometry.discrete.CylinderTriangulator

public final class CylinderTriangulator
extends Object

Triangulates a cylinder. It is recommended to visualize the cylinder using a SolidPrimitive. Although, if only the fill is desired for visualization, a TriangleMeshPrimitive with RenderBackThenFrontFaces (get) set to true can be used. Likewise, if only the outline is desired, a PolylinePrimitive can be used.

Method Detail

compute

public static final SolidTriangulatorResult compute(double length,
                                                    double radius)

Computes the triangulation for a cylinder centered at the origin.

Parameters:

length - The length, in meters, of the cylinder along the z axis.

radius - The radius, in meters, of the cylinder.

Returns:

A SolidTriangulatorResult object representing the triangulation.

Throws:

ArgumentOutOfRangeException - length must be greater than or equal to 0.

ArgumentOutOfRangeException - radius must be greater than 0.

                                                    CylinderFill cylinderFill)

Computes the triangulation for a cylinder centered at the origin.

slices determines the detail of the triangulation. More slices results in a precise cylinder but uses more memory.

A wide variety of shapes can be created using bottomRadius, topRadius, and cylinderFill. A lamp shade is created when bottomRadius is different than topRadius. When one radii is zero, a cone is created. When cylinderFill does not include Wall, one or two circles aligned to the xy plane are created.

Parameters:

length - The length, in meters, of the cylinder along the z axis.

bottomRadius - The radius, in meters, of the cylinder's bottom cap.

topRadius - The radius, in meters, of the cylinder's top cap.

slices - The number of slices around the z axis.

cylinderFill - Flags enumeration indicating what cylinder faces should be filled. Values can be logically ored together.

Returns:

A SolidTriangulatorResult object representing the triangulation.

Throws:

ArgumentOutOfRangeException - length must be greater than or equal to 0.

ArgumentOutOfRangeException - bottomRadius and topRadius must be greater than or equal to 0. Both cannot equal 0.

ArgumentOutOfRangeException - slices must be greater than or equal to 3.

UnsupportedCaseException - cylinderFill must be a valid enumeration value in CylinderFill.
