Properties

AdditionalProperties

Additional properties on glTF JSON objects. Those properties may have been added by a new, unsupported version of the glTF specification. For extending glTF, please use extensions or extras instead.

Declaration

[JsonIgnore]
public ReadOnlyProperties AdditionalProperties { get; }

Property Value

Type	Description
ReadOnlyProperties

Attributes

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

Declaration

[JsonPropertyName("attributes")]
public Attributes Attributes { get; set; }

Property Value

Type	Description
Attributes

Extensions

Mesh primitive extensions

Declaration

[JsonPropertyName("extensions")]
public MeshPrimitiveExtensions Extensions { get; set; }

Property Value

Type	Description
MeshPrimitiveExtensions

Extras

Application-specific data.

Declaration

[JsonPropertyName("extras")]
[JsonConverter(typeof(ExtrasConverter))]
public ExtrasContainer Extras { get; set; }

Property Value

Type	Description
ExtrasContainer

Indices

The index of the accessor that contains mesh indices. When this is not defined, the primitives should be rendered without indices using drawArrays(). When defined, the accessor must contain indices: the bufferView referenced by the accessor must have a target equal to 34963 (ELEMENT_ARRAY_BUFFER); a byteStride that is tightly packed, i.e., 0 or the byte size of componentType in bytes; componentType must be 5121 (UNSIGNED_BYTE), 5123 (UNSIGNED_SHORT) or 5125 (UNSIGNED_INT), the latter is only allowed when OES_element_index_uint extension is used; type must be \"SCALAR\".

Declaration

[JsonPropertyName("indices")]
public int? Indices { get; set; }

Property Value

Type	Description
int?

IsDracoCompressed

Declaration

[JsonIgnore]
public bool IsDracoCompressed { get; }

Property Value

Type	Description
bool

Material

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

Declaration

[JsonPropertyName("material")]
public int? Material { get; set; }

Property Value

Type	Description
int?

Mode

The type of primitives to render. All valid values correspond to WebGL enums.

Declaration

[JsonIgnore]
public PrimitiveMode Mode { get; set; }

Property Value

Type	Description
PrimitiveMode

Targets

An array of Morph Targets, each Morph Target is a dictionary mapping attributes to their deviations in the Morph Target (index of the accessor containing the attribute displacements' data).

Declaration

[JsonPropertyName("targets")]
public List<MorphTarget> Targets { get; set; }

Property Value

Type	Description
List<MorphTarget>

Methods

Clone()

Clones the object

Declaration

public object Clone()

Returns

Type	Description
object	Member-wise clone

GetMaterialIndex(int)

Provides the glTF material index, given a materials variant index. If variantIndex is invalid (e.g. negative) or the slot does not have a material override for the given variantIndex, it returns the default material index.

Declaration

public int? GetMaterialIndex(int variantIndex)

Parameters

Type	Name	Description
int	variantIndex	Materials variant index.

Returns

Type	Description
int?	Corresponding glTF material index, or null when no material is assigned.
