QuatAttribute (object)

Specialized GeometryAttribute containing one Quat per element. Values can be accessed with the QuatAttribute.values array member, but its usage might be restricted by the owner Geometry.

Members

UInt32	version
String	name
UInt32	containerIndex
StatisticsAutoRegisterMember	autoStats
Size	count
Ref<GeometryAttributes>	container
Quat[]	values	Values array container
Boolean	normalize	If true, IntegerAttribute.linearCombine and IntegerAttribute.getLinearCombination will normalize the resulting value.

Methods in detail

QuatAttribute ( in QuatAttribute other )

copy constructor

---

QuatAttribute ()

default constructor

---

Boolean QuatAttribute.checkConsistency? ()

バージョン 2.4.0 で追加.

Checks the attribute data consistency.

---

QuatAttribute QuatAttribute.clone? ()

clone method

---

QuatAttribute.cloneMembersTo? ( io QuatAttribute that )

---

QuatAttribute.convertToCPU! ()

---

QuatAttribute.convertToGPU! ()

---

QuatAttribute.copyValue! ( in Ref<Object> sourceAttr, in Size sourceIndex, in Size targetIndex )

Replaces the value located at targetIndex with source attribute’s value located at sourceIndex. The source attribute will be of the same type.

---

QuatAttribute.copyValue! ( in Size sourceIndex, in Size targetIndex )

Replaces the value located at targetIndex with the value located at sourceIndex

---

Data QuatAttribute.data? ()

Returns a raw pointer to contiguous attribute data, if applicable, and an uninitialized Data otherwise.

---

Boolean QuatAttribute.equalValues? ( in Size index1, in Size index2 )

Return true if two values are logically equal.

---

UInt32 QuatAttribute.getElementsMemType? ()

---

Quat QuatAttribute.getLinearCombination? ( in LocalL16UInt32Array sourceIndices, in LocalL16ScalarArray sourceWeights )

Returns a linear combination of source values. If QuatAttribute.normalize, the resulting value will be normalized.

sourceIndices	The array of source indices
sourceWeights	The array of source weights, which need to correspond to each sourceIndices. Normally the sum of the weights should be 1.0

---

Size QuatAttribute.getScalarValueSize? ()

If all attribute values can be expressed as a constant Scalar array, returns the constant number of elements, 0 otherwise.

参考

GeometryAttribute.setFromScalar

---

QuatAttribute.linearCombine! ( in Ref<Object> sourceAttr, in LocalL16UInt32Array sourceIndices, in LocalL16ScalarArray sourceWeights, in Size targetIndex )

Sets the value located at targetIndex as a linear combination of other values.

source	The attribute for source values
sourceIndices	The array of source indices, relatively to the source attribute.
sourceWeights	The array of source weights, which need to correspond to each sourceIndices. Normally the sum of the weights should be 1.0.
targetIndex	The target value index.

---

QuatAttribute.resize! ( in Size count )

Resizes the attribute array.

---

QuatAttribute.setContainerIndex! ( in Size index )

---

QuatAttribute.setFromScalar! ( in Size index, in LocalL16ScalarArray value )

If applicable, sets an attribute value from an array of Scalars. This array must have a size of GeometryAttribute.getScalarValueSize .

---

String QuatAttribute.truncateDecimalsPrint? ( in Size index, in UInt32 n )

Returns a description of the value, keeping the first n decimals (Float32 or Float64 based values).

---

String QuatAttribute.unitTestPrint? ( in Size index )

Returns a numerically stable description of the value

---

String QuatAttribute.valueDesc? ( in Size index )

Returns a description of the value
