Public Member Functions
int64_t	getSizeBytes () const
	Calculates the size in bytes of this object, including the contents of all collections, pointers, and strings. This will NOT include the size of any extensions attached to the object. Calling this method may be slow as it requires traversing the object's entire structure.

Public Member Functions inherited from CesiumUtility::ExtensibleObject
template<typename T>
bool	hasExtension () const noexcept
	Checks if an extension exists given its static type.

template<typename T>
const T *	getExtension () const noexcept
	Gets an extension given its static type.

template<typename T>
T *	getExtension () noexcept
	Gets an extension given its static type.

const JsonValue *	getGenericExtension (const std::string &extensionName) const noexcept
	Gets a generic extension with the given name as a `CesiumUtility::JsonValue`.

JsonValue *	getGenericExtension (const std::string &extensionName) noexcept
	Gets a generic extension with the given name as a `CesiumUtility::JsonValue`.

template<typename T, typename... ConstructorArgumentTypes>
T &	addExtension (ConstructorArgumentTypes &&... constructorArguments)
	Adds a statically-typed extension to this object.

template<typename T>
void	removeExtension ()
	Removes a statically-typed extension from this object.

int64_t	getSizeBytes () const
	Calculates the size in bytes of this ExtensibleObject, including all of its extras but NOT including its extensions. Calling this method may be slow as it requires traversing the entire object.

Public Attributes
int32_t	visibility = -1
	The index of the accessor encoding the visibility of each triangle edge as a bitfield with two bits per edge.

int32_t	material = -1
	The index of a glTF material with which the edges are to be drawn.

int32_t	silhouetteNormals = -1
	The index of the accessor encoding the pair of outward-facing normals for the two faces sharing each silhouette edge (visibility 1) encoded in `visibility`.

std::vector< CesiumGltf::LineString >	lineStrings
	An array of edges encoded as line strings.

Public Attributes inherited from CesiumUtility::ExtensibleObject
std::unordered_map< std::string, std::any >	extensions
	The extensions attached to this object.

	Application-specific data.

JsonValue::Object	unknownProperties
	Unknown properties that exist on this object but do not have any representation in the statically-typed classes.

Static Public Attributes
static constexpr const char *	TypeName
	The original name of this type.

static constexpr const char *	ExtensionName
	The official name of the extension. This should be the same as its key in the `extensions` object.

Member Function Documentation

◆ getSizeBytes()

int64_t CesiumGltf::ExtensionExtMeshPrimitiveEdgeVisibilitySpec::getSizeBytes ( ) const

inline

Calculates the size in bytes of this object, including the contents of all collections, pointers, and strings. This will NOT include the size of any extensions attached to the object. Calling this method may be slow as it requires traversing the object's entire structure.

Member Data Documentation

◆ ExtensionName

const char* CesiumGltf::ExtensionExtMeshPrimitiveEdgeVisibilitySpec::ExtensionName

staticconstexpr

Initial value:

=

"EXT_mesh_primitive_edge_visibility"

The official name of the extension. This should be the same as its key in the extensions object.

Definition at line 26 of file ExtensionExtMeshPrimitiveEdgeVisibilitySpec.h.

◆ lineStrings

std::vector<CesiumGltf::LineString> CesiumGltf::ExtensionExtMeshPrimitiveEdgeVisibilitySpec::lineStrings

An array of edges encoded as line strings.

Edges encoded as line strings MUST NOT also be encoded by the visibility property.

Definition at line 63 of file ExtensionExtMeshPrimitiveEdgeVisibilitySpec.h.

◆ material

int32_t CesiumGltf::ExtensionExtMeshPrimitiveEdgeVisibilitySpec::material = -1

The index of a glTF material with which the edges are to be drawn.

If omitted, the edges are drawn using the same material as the triangle mesh primitive.

Definition at line 45 of file ExtensionExtMeshPrimitiveEdgeVisibilitySpec.h.

◆ silhouetteNormals

int32_t CesiumGltf::ExtensionExtMeshPrimitiveEdgeVisibilitySpec::silhouetteNormals = -1

The index of the accessor encoding the pair of outward-facing normals for the two faces sharing each silhouette edge (visibility 1) encoded in visibility.

This property MUST be defined if and only if visibility encodes at least one edge with visibility value 1.

Definition at line 55 of file ExtensionExtMeshPrimitiveEdgeVisibilitySpec.h.

◆ TypeName

const char* CesiumGltf::ExtensionExtMeshPrimitiveEdgeVisibilitySpec::TypeName

staticconstexpr

Initial value:

=

"ExtensionExtMeshPrimitiveEdgeVisibility"

The original name of this type.

Definition at line 22 of file ExtensionExtMeshPrimitiveEdgeVisibilitySpec.h.

◆ visibility

int32_t CesiumGltf::ExtensionExtMeshPrimitiveEdgeVisibilitySpec::visibility = -1

The index of the accessor encoding the visibility of each triangle edge as a bitfield with two bits per edge.

An edge visibility of 0 indicates the edge is never drawn; 1 indicates the edge is only drawn in silhouette; 2 indicates a 'hard' (always-drawn) edge; and 3 indicates a repeated occurrence of a 'hard' edge.
