Properties

SceneInstance

Contains information about the latest instance of a glTF scene

Declaration

public GameObjectSceneInstance SceneInstance { get; protected set; }

Property Value

Type	Description
GameObjectSceneInstance

SceneTransform

Transform representing the scene. Root nodes will get parented to it.

Methods

AddAnimation(AnimationClip[])

Adds animation clips to the current scene. Only available if the built-in Animation module is enabled.

Declaration

public void AddAnimation(AnimationClip[] animationClips)

Parameters

Type	Name	Description
AnimationClip[]	animationClips	Animation clips

AddCamera(uint, uint)

Called when a node has a camera assigned

Declaration

public virtual void AddCamera(uint nodeIndex, uint cameraIndex)

Parameters

Type	Name	Description
uint	nodeIndex	Index of the node
uint	cameraIndex	Index of the assigned camera

AddLightPunctual(uint, uint)

Called when a node has a punctual light assigned (KHR_lights_punctual)

Declaration

public void AddLightPunctual(uint nodeIndex, uint lightIndex)

Parameters

Type	Name	Description
uint	nodeIndex	Index of the node
uint	lightIndex	Index of the punctual light

AddPrimitive(uint, string, MeshResult, uint[], uint?, float[], int)

Called for adding a Primitive/Mesh to a Node.

Declaration

public virtual void AddPrimitive(uint nodeIndex, string meshName, MeshResult meshResult, uint[] joints = null, uint? rootJoint = null, float[] morphTargetWeights = null, int primitiveNumeration = 0)

Parameters

Type	Name	Description
uint	nodeIndex	Index of the node
string	meshName	Mesh's name
MeshResult	meshResult	The converted Mesh
uint[]	joints	If a skin was attached, the joint indices. Null otherwise
uint?	rootJoint	Root joint node index, if present
float[]	morphTargetWeights	Morph target weights, if present
int	primitiveNumeration	Primitives are numerated per Node, starting with 0

AddPrimitiveInstanced(uint, string, MeshResult, uint, NativeArray<Vector3>?, NativeArray<Quaternion>?, NativeArray<Vector3>?, int)

Called for adding a Primitive/Mesh to a Node that uses GPU instancing (EXT_mesh_gpu_instancing) to render the same mesh/material combination many times. Similar to/called instead of AddPrimitive(uint, string, MeshResult, uint[], uint?, float[], int), without joints/skin support.

Declaration

public virtual void AddPrimitiveInstanced(uint nodeIndex, string meshName, MeshResult meshResult, uint instanceCount, NativeArray<Vector3>? positions, NativeArray<Quaternion>? rotations, NativeArray<Vector3>? scales, int primitiveNumeration = 0)

Parameters

Type	Name	Description
uint	nodeIndex	Index of the node
string	meshName	Mesh's name
MeshResult	meshResult	The converted Mesh
uint	instanceCount	Number of instances
NativeArray<Vector3>?	positions	Instance positions
NativeArray<Quaternion>?	rotations	Instance rotations
NativeArray<Vector3>?	scales	Instance scales
int	primitiveNumeration	Primitives are numerated per Node, starting with 0

BeginScene(string, uint[])

Starts creating a scene instance. Has to be called at first and concluded by calling EndScene(uint[]).

Declaration

public virtual void BeginScene(string name, uint[] rootNodeIndices)

Parameters

Type	Name	Description
string	name	Name of the scene
uint[]	rootNodeIndices	Indices of root level nodes in scene

CreateNode(uint, uint?, Vector3, Quaternion, Vector3)

Called for every Node in the glTF file

Declaration

public void CreateNode(uint nodeIndex, uint? parentIndex, Vector3 position, Quaternion rotation, Vector3 scale)

Parameters

Type	Name	Description
uint	nodeIndex	Index of node. Serves as identifier.
uint?	parentIndex	Index of the parent's node. If it's null, the node's a root-level node
Vector3	position	Node's local position in hierarchy
Quaternion	rotation	Node's local rotation in hierarchy
Vector3	scale	Node's local scale in hierarchy

EndScene(uint[])

Is called at last, after all scene content has been created. Immediately afterwards the scene will be rendered, so use it to finally prepare the instance.

Declaration

public virtual void EndScene(uint[] rootNodeIndices)

Parameters

Type	Name	Description
uint[]	rootNodeIndices	Indices of root level nodes in scene

SetNodeName(uint, string)

Sets the name of a node. If a node has no name it falls back to the first valid mesh name. Null otherwise.

Declaration

public virtual void SetNodeName(uint nodeIndex, string name)

Parameters

Type	Name	Description
uint	nodeIndex	Index of the node to be named.
string	name	Valid name or null
