Accessor

@Serializable

data class Accessor(var name: String? = null, val bufferView: Int = 0, val byteOffset: Int = 0, val componentType: Int = 0, val normalized: Boolean = false, val count: Int = 1, val min: FloatArray = FloatArray(0), val max: FloatArray = FloatArray(0), val type: GLTF2.AccessorType = AccessorType.SCALAR, val sparse: JsonElement? = null, val extensions: JsonElement? = null, val extras: JsonElement? = null) : GLTFProperty

Constructors

Accessor

constructor(name: String? = null, bufferView: Int = 0, byteOffset: Int = 0, componentType: Int = 0, normalized: Boolean = false, count: Int = 1, min: FloatArray = FloatArray(0), max: FloatArray = FloatArray(0), type: GLTF2.AccessorType = AccessorType.SCALAR, sparse: JsonElement? = null, extensions: JsonElement? = null, extras: JsonElement? = null)

Properties

attachDebugName

var attachDebugName: String?

bufferView

val bufferView: Int = 0

The index of the buffer view. When undefined, the accessor MUST be initialized with zeros; sparse property or extensions MAY override zeros with actual values.

byteOffset

val byteOffset: Int = 0

The offset relative to the start of the buffer view in bytes.

bytesPerEntry

val bytesPerEntry: Int

componentTType

val componentTType: VarKind

componentType

val componentType: Int = 0

The datatype of the accessor's components. UNSIGNED_INT type MUST NOT be used for any accessor that is not referenced by mesh.primitive.indices. type parameter of vertexAttribPointer(). The corresponding typed arrays are Int8Array, Uint8Array, Int16Array, Uint16Array, Uint32Array, and Float32Array.

count

val count: Int = 1

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

extensions

open override val extensions: JsonElement? = null

JSON object with extension-specific objects.

extras

open override val extras: JsonElement? = null

Although extras MAY have any type, it is common for applications to store and access custom data as key/value pairs. Therefore, extras SHOULD be a JSON object rather than a primitive value for best portability.

max

val max: FloatArray

Maximum value of each component in this accessor.

min

val min: FloatArray

Minimum value of each component in this accessor.

name

open override var name: String?

ncomponent

val ncomponent: Int

normalized

val normalized: Boolean = false
