Enum Class SoInstanceParameter.PredefinedParameters

java.lang.Object

java.lang.Enum<SoInstanceParameter.PredefinedParameters>

com.openinventor.inventor.nodes.SoInstanceParameter.PredefinedParameters

All Implemented Interfaces:

IntegerValuedEnum, Serializable, Comparable<SoInstanceParameter.PredefinedParameters>, Constable

Enclosing class:

SoInstanceParameter

public static enum SoInstanceParameter.PredefinedParameters
extends Enum<SoInstanceParameter.PredefinedParameters>
implements IntegerValuedEnum

List of predefined per-instance attribute names. The names corresponding to the following enum symbols can be queried by mean of the getPredefinedParameterName() method. They correspond to a set of predefined parameter names that are automatically managed/interpreted:

• OivShapeInstanceTranslation: Handles an array of vec3f translation to apply to vertices of each instance.
  
• OivShapeInstanceScale: Handles an array of vec3f scale factor applied to vertices of each instance.
  
• OivShapeInstanceRotation: Handles an array of vec4f quaternion applied to vertices of each instance.
  
• OivShapeInstanceColor: Handles an array of vec3f color applied to vertices of each instance.
  
• OivShapeInstanceTransparency: Handles an array of float transparency applied to vertices of each instance.
  
• OivShapeInstanceVisibility: Handles an array of int32 visibility flag to apply to each instance.

OivShapeInstanceTranslation, OivShapeInstanceScale and OivShapeInstanceRotation are combined together to create an equivalent matrix available in GLSL shaders with the function

 mat4 OivInstanceMatrix() 

If no parameters are present then an identity matrix is returned.

OivShapeInstanceColor and OivShapeInstanceTransparency affect, respectively, the diffuse color and the transparency of each instance. Note that when one of these parameters is defined, it overrides the diffuse color or the transparency value of a SoMaterial node.

OivShapeInstanceVisibility affects the visibility of each instance (i.e. 0 means hidden and a value greater than zero means visible). This attribute is available in GLSL shaders with the function

 int OivInstanceVisibility() 

.

Method Details

values

public static SoInstanceParameter.PredefinedParameters[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static SoInstanceParameter.PredefinedParameters valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

valueOf

public static SoInstanceParameter.PredefinedParameters valueOf(int val)

Returns the enum constant of this type with the specified integer value

Returns:

the enum constant of this type with the specified integer value.

getValue

public int getValue()

Description copied from interface: IntegerValuedEnum

Returns the integer value of the enum constant.

Specified by:

getValue in interface IntegerValuedEnum

Returns:

the integer value of the enum constant.
