Syntax

public abstract class MeshPrimitiveBase : ICloneable, IMaterialsVariantsSlot
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)
Determines whether two object instances are equal.
Declaration
public override bool Equals(object obj)
Parameters
| Type | Name | Description |
|---|---|---|
| object | obj | The object to compare with the current object. |
Returns
| Type | Description |
|---|---|
| bool | true if the specified object is equal to the current object; otherwise, false. |
Overrides
GetHashCode()
Default hash function.
Declaration
public override int GetHashCode()
Returns
| Type | Description |
|---|---|
| int | A hash code for the current object. |
Overrides
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. |
