Vec2Attribute (object)

Specialized GeometryAttribute containing one Vec2 per element. Values can be accessed with the Vec2Attribute.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
Vec2[]	values	Values array container

Methods in detail

Vec2Attribute ( in Vec2Attribute other )

copy constructor

---

Vec2Attribute ()

default constructor

---

Boolean Vec2Attribute.checkConsistency? ()

バージョン 2.4.0 で追加.

Checks the attribute data consistency.

---

Vec2Attribute Vec2Attribute.clone? ()

clone method

---

Vec2Attribute.cloneMembersTo? ( io Vec2Attribute that )

---

Vec2Attribute.convertToCPU! ()

---

Vec2Attribute.convertToGPU! ()

---

Vec2Attribute.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.

---

Vec2Attribute.copyValue! ( in Size sourceIndex, in Size targetIndex )

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

---

Data Vec2Attribute.data? ()

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

---

Boolean Vec2Attribute.equalValues? ( in Size index1, in Size index2 )

Return true if two values are logically equal.

---

UInt32 Vec2Attribute.getElementsMemType? ()

---

Vec2 Vec2Attribute.getLinearCombination? ( in LocalL16UInt32Array sourceIndices, in LocalL16ScalarArray sourceWeights )

Returns a linear combination of source values.

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 Vec2Attribute.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

---

Vec2Attribute.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.

---

Vec2Attribute.resize! ( in Size count )

Resizes the attribute array.

---

Vec2Attribute.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 Vec2Attribute.truncateDecimalsPrint? ( in Size index, in UInt32 n )

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

---

String Vec2Attribute.unitTestPrint? ( in Size index )

Returns a numerically stable description of the value

---

String Vec2Attribute.valueDesc? ( in Size index )

Returns a description of the value
