Fields

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
public Attributes attributes
Field Value
Type Description
Attributes

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
public int indices
Field Value
Type Description
int

material

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

Declaration
public int material
Field Value
Type Description
int

mode

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

Declaration
public DrawMode mode
Field Value
Type Description
DrawMode

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
public MorphTarget[] targets
Field Value
Type Description
MorphTarget[]

Properties

Extensions

Mesh primitive extensions

Declaration
public abstract MeshPrimitiveExtensions Extensions { get; }
Property Value
Type Description
MeshPrimitiveExtensions

IsDracoCompressed

Declaration
public bool IsDracoCompressed { get; }
Property Value
Type Description
bool

Methods

Clone()

Clones the object

Declaration
public object Clone()
Returns
Type Description
object

Member-wise clone

Equals(object)

Primitives are considered equal if their attributes and morph targets (if existing) are equal. This is practical when clustering primitives of a mesh together, that end up in a single Unity Mesh.

Declaration
public override bool Equals(object obj)
Parameters
Type Name Description
object obj

Object to compare against
Returns
Type Description
bool

True if attributes and morph targets are equal, false otherwise
Overrides

GetHashCode()

Default hash function.

Declaration
public override int GetHashCode()
Returns
Type Description
int

A hash code for the current object.
