Fields

bufferView

The index of the bufferView. If this is undefined, look in the sparse object for the index and value buffer views.

Declaration

public int bufferView

Field Value

Type	Description
Int32

bufferView

The index of the bufferView. If this is undefined, look in the sparse object for the index and value buffer views.

Declaration

public int bufferView

Field Value

Type	Description
Int32

byteOffset

The offset relative to the start of the bufferView in bytes. This must be a multiple of the size of the component datatype.

Declaration

public int byteOffset

Field Value

Type	Description
Int32

byteOffset

The offset relative to the start of the bufferView in bytes. This must be a multiple of the size of the component datatype.

Declaration

public int byteOffset

Field Value

Type	Description
Int32

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.

Declaration

public GltfComponentType componentType

Field Value

Type	Description
GltfComponentType

Declaration

public GltfComponentType componentType

Field Value

Type	Description
GltfComponentType

count

The number of attributes referenced by this accessor, not to be confused with the number of bytes or number of components. 1

Declaration

public int count

Field Value

Type	Description
Int32

count

The number of attributes referenced by this accessor, not to be confused with the number of bytes or number of components. 1

Declaration

public int count

Field Value

Type	Description
Int32

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. 1 16

Declaration

public float[] max

Field Value

Type	Description
Single[]

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.

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. 1 16

Declaration

public float[] max

Field Value

Type	Description
Single[]

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.

Declaration

public float[] min

Field Value

Type	Description
Single[]

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.

Declaration

public bool normalized

Field Value

Type	Description
Boolean

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.

Declaration

public bool normalized

Field Value

Type	Description
Boolean

sparse

Declaration

public GltfAccessorSparse sparse
