java.lang.Enum<Viewer.RotationMode>

maspack.render.Viewer.RotationMode

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Viewer.RotationMode>

Enclosing interface:

Viewer

public static enum Viewer.RotationMode
extends java.lang.Enum<Viewer.RotationMode>

Controls how the viewer responds to rotation control inputs specified as horizontal and vertical angular displacements in the viewing plane.

Enum Constant Summary

Enum Constants

Enum Constant and Description
CONTINUOUS The horizontal and vertical displacements describe instantaneous angular velocity components of the eye-to-world rotation.
FIXED_VERTICAL The horizontal displacement describes a rotation about the vertical (``up'') direction (as returned by Viewer.getUpVector()), while the vertical displacement controls the elevation of the eye position.
OFF Viewer rotation is disabled.

Method Summary

Modifier and Type	Method and Description
static Viewer.RotationMode	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.
static Viewer.RotationMode[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

FIXED_VERTICAL

public static final Viewer.RotationMode FIXED_VERTICAL

The horizontal displacement describes a rotation about the vertical (``up'') direction (as returned by Viewer.getUpVector()), while the vertical displacement controls the elevation of the eye position. This mode has the advantage that the ``up'' direction always remains parallel to the vertical direction of the viewer plane. However, because of this, the eye-to-world rotation cannot be adjusted to an arbitrary value.

CONTINUOUS

public static final Viewer.RotationMode CONTINUOUS

The horizontal and vertical displacements describe instantaneous angular velocity components of the eye-to-world rotation. This allows the eye-to-world rotation to be adjusted to arbitrary values, but the ``up'' direction will generally not remain parallel to the vertical direction of the viewer plane.

OFF

public static final Viewer.RotationMode OFF

Viewer rotation is disabled.

Method Detail

values

public static Viewer.RotationMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Viewer.RotationMode c : Viewer.RotationMode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Viewer.RotationMode valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
