AttributeSpec

AttributeSpec

Describes data structure of a single data attribute, such as a scalar, or a vector This structure is designed to map well to GPU shader formats and is intended for larger datasets, such as meshes or particle clouds

Kind: global class

• AttributeSpec
  • instance
    • .name : string

attributeSpec.name : string

Typically unique within a given set, used to identify the attribute

Kind: instance property of AttributeSpec

attributeSpec.type : BinaryDataType

How the attribute is stored in memory and interpreted

Kind: instance property of AttributeSpec

attributeSpec.itemSize : number

How many elements the attribute uses. This is cardinality of a vector. 1 means the attribute is a scalar must be greater or equal to 1

Kind: instance property of AttributeSpec

attributeSpec.normalized : boolean

Normalized values will be automatically converted to float32 in the shader This gives good optimization opportunities for things like normal vectors Applies to integer types only

Kind: instance property of AttributeSpec

attributeSpec.isAttributeSpec : boolean

Kind: instance property of AttributeSpec
Read only: true

attributeSpec.equals(other) ⇒ boolean

Kind: instance method of AttributeSpec

Param	Type
other	AttributeSpec

attributeSpec.copy(other)

Kind: instance method of AttributeSpec

Param	Type
other	AttributeSpec

attributeSpec.getByteSize() ⇒ number

How much space a single attribute value takes up

Kind: instance method of AttributeSpec
Returns: number - in bytes

AttributeSpec.byName(a, b) ⇒ number

Sorting comparator

Kind: static method of AttributeSpec

Param	Type
a	AttributeSpec
b	AttributeSpec
