Class AccessorBase

An accessor defines a method for retrieving data as typed arrays from within a buffer view. See . accessor in the glTF 2.0 specification.

Fields

Name	Description
bufferView	The index of the bufferView. If this is undefined, look in the sparse object for the index and value buffer views.
byteOffset	The offset relative to the start of the bufferView in bytes. This must be a multiple of the size of the component datatype.
componentType	The datatype of components in the attribute. All valid values correspond to WebGL enums. The corresponding typed arrays are: Int8Array, Uint8Array, Int16Array, Uint16Array, Uint32Array, and Float32Array, respectively. 5125 (UNSIGNED_INT) is only allowed when the accessor contains indices i.e., the accessor is only referenced by primitive.indices.
count	The number of attributes referenced by this accessor, not to be confused with the number of bytes or number of components.
max	Maximum value of each component in this attribute. Both min and max arrays have the same length. The length is determined by the value of the type property; it can be 1, 2, 3, 4, 9, or 16. When componentType is 5126 (FLOAT) each array value must be stored as double-precision JSON number with numerical value which is equal to buffer-stored single-precision value to avoid extra runtime conversions. normalized property has no effect on array values: they always correspond to the actual values stored in the buffer. When accessor is sparse, this property must contain max values of accessor data with sparse substitution applied.
min	Minimum value of each component in this attribute. Both min and max arrays have the same length. The length is determined by the value of the type property; it can be 1, 2, 3, 4, 9, or 16. When componentType is 5126 (FLOAT) each array value must be stored as double-precision JSON number with numerical value which is equal to buffer-stored single-precision value to avoid extra runtime conversions. normalized property has no effect on array values: they always correspond to the actual values stored in the buffer. When accessor is sparse, this property must contain min values of accessor data with sparse substitution applied.
normalized	Specifies whether integer data values should be normalized (true) to [0, 1] (for unsigned types) or [-1, 1] (for signed types), or converted directly (false) when they are accessed. Must be false when accessor is used for animation data.
type	Specifies if the attribute is a scalar, vector, or matrix, and the number of elements in the vector or matrix.

Properties

Name	Description
ByteSize	Overall, byte size. Ignores interleaved or sparse accessors
ElementByteSize	Byte size of one element
IsSparse	True if the accessor is sparse
Sparse	Sparse storage of attributes that deviate from their initialization value.

Methods

Name	Description
GetAccessorAttributeType(int)	Get one-dimensional glTF attribute type by number of components per elements. Note that this does not support matrix types.
GetAccessorAttributeTypeLength(GltfAccessorAttributeType)	Get number of components of glTF attribute type.
GetAttributeType()	GltfAccessorAttributeType typed/cached getter from the type string.
GetComponentType(VertexAttributeFormat)	Converts Unity vertex attribute format to glTF component type.
GetComponentTypeSize(GltfComponentType)	Provides size of components by type
SetAttributeType(GltfAccessorAttributeType)	GltfAccessorAttributeType typed setter for the type string.
TryGetBounds()	For 3D positional data, returns accessor's bounding box. Applies coordinate system transform (glTF to Unity)
