Primitive

@Serializable

data class Primitive(var name: String? = null, val attributes: Map<GLTF2.PrimitiveAttribute, Int> = emptyMap(), val indices: Int? = null, val material: Int? = null, val mode: Int = 4, val targets: List<Map<GLTF2.PrimitiveAttribute, Int>> = emptyList(), val extensions: JsonElement? = null, val extras: JsonElement? = null) : GLTFProperty

Constructors

Primitive

constructor(name: String? = null, attributes: Map<GLTF2.PrimitiveAttribute, Int> = emptyMap(), indices: Int? = null, material: Int? = null, mode: Int = 4, targets: List<Map<GLTF2.PrimitiveAttribute, Int>> = emptyList(), extensions: JsonElement? = null, extras: JsonElement? = null)

Properties

attributes

val attributes: Map<GLTF2.PrimitiveAttribute, Int>

A plain JSON object, where each key corresponds to a mesh attribute semantic and each value is the index of the accessor containing attribute's data.

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.

indices

val indices: Int? = null

The index of the accessor that contains the vertex indices. When this is undefined, the primitive defines non-indexed geometry. When defined, the accessor MUST have SCALAR type and an unsigned integer component type.

material

val material: Int? = null

The index of the material to apply to this primitive when rendering.

mode

val mode: Int = 4

The topology type of primitives to render.

name

open override var name: String?

targets

val targets: List<Map<GLTF2.PrimitiveAttribute, Int>>

An array of morph targets. Morph targets: one per morphing weight. Typically, 4 as max for standard. A plain JSON object specifying attributes displacements in a morph target, where each key corresponds to one of the three supported attribute semantic (POSITION, NORMAL, or TANGENT) and each value is the index of the accessor containing the attribute displacements' data.
