Properties details ​

Name ​

The name of the AttributeTessellation object. (Inherited from Object)

// Setter
void SetName( const char * name ) const;

// Getter
spString GetName() const;

// Setter
void SetName(string name);

// Getter
string GetName();

# Setter
None SetName(name: str)

# Getter
str GetName()

Methods details ​

AddObserver ​

Adds a user-defined observer object to the interface, that will receive events from the interface. (Inherited from Object)

rid AddObserver( const spObserver & observer ) const;

int AddObserver(spObserver observer);

int AddObserver(observer: spObserver)

FilterOpacityOnDisplacementEdges ​

Filter opacity based on displacement curvature, to separate out islands of different heights. Basically clears opacity values on all triangles where the absolute slope of displacement is above a set threshold. Note that the scene geometries must have both Opacity and Displacement as tessellated attributes.

bool FilterOpacityOnDisplacementEdges( const spScene & scene , real slopeThreshold ) const;

bool FilterOpacityOnDisplacementEdges(spScene scene, float slopeThreshold);

bool FilterOpacityOnDisplacementEdges(scene: spScene, slopeThreshold: float)

GetClass ​

Get the name of the AttributeTessellation class. (Inherited from Object)

spString GetClass() const;

string GetClass();

str GetClass()

InjectDisplacementDataIntoScene ​

Fetch displacement data from the supplied material table and texture table, and inject into the displacement data tessellated attribute. Allowed attribute formats are U16 or F32vec3.

bool InjectDisplacementDataIntoScene( const spScene & scene , const spAttributeTessellationSamplingSettings & settings , const spMaterialTable & materials , const spTextureTable & textures ) const;

bool InjectDisplacementDataIntoScene(spScene scene, spAttributeTessellationSamplingSettings settings, spMaterialTable materials, spTextureTable textures);

bool InjectDisplacementDataIntoScene(scene: spScene, settings: spAttributeTessellationSamplingSettings, materials: spMaterialTable, textures: spTextureTable)

InjectOpacityDataIntoScene ​

Fetch opacity data from the supplied material table and texture table, and inject into the opacity data tessellated attribute. Attribute format will always be U8.

bool InjectOpacityDataIntoScene( const spScene & scene , const spAttributeTessellationSamplingSettings & settings , const spMaterialTable & materials , const spTextureTable & textures ) const;

bool InjectOpacityDataIntoScene(spScene scene, spAttributeTessellationSamplingSettings settings, spMaterialTable materials, spTextureTable textures);

bool InjectOpacityDataIntoScene(scene: spScene, settings: spAttributeTessellationSamplingSettings, materials: spMaterialTable, textures: spTextureTable)

IsSameObjectAs ​

Returns true if the AttributeTessellation object is valid. (Inherited from Object)

bool IsSameObjectAs( const spObject & object ) const;

bool IsSameObjectAs(spObject object);

bool IsSameObjectAs(object: spObject)

NewTessellatedGeometry ​

Generates a new tessellated geometry with tessellated attributes applied.

spGeometryData NewTessellatedGeometry( const spGeometryData & sourceGeometry ) const;

spGeometryData NewTessellatedGeometry(spGeometryData sourceGeometry);

spGeometryData NewTessellatedGeometry(sourceGeometry: spGeometryData)

bool NonNull()

PrintInfo ​

Prints the content/info of the AttributeTessellation object to the log. (Inherited from Object)

void PrintInfo() const;

void PrintInfo();

None PrintInfo()

RemoveObserver ​

Removes a previously added observer object. (Inherited from Object)

void RemoveObserver( rid observerId ) const;

void RemoveObserver(int observerId);

None RemoveObserver(observerId: int)

SetupAttributeTessellationOnGeometry ​

Sets up attribute tessellation setup and primitive tessellation on a single geometry.

bool SetupAttributeTessellationOnGeometry( const spGeometryData & geometry , const spAttributeTessellationSettings & settings ) const;

bool SetupAttributeTessellationOnGeometry(spGeometryData geometry, spAttributeTessellationSettings settings);

bool SetupAttributeTessellationOnGeometry(geometry: spGeometryData, settings: spAttributeTessellationSettings)

Static methods details ​

IsClassA ​

Returns true if the class is a or is a descendant of the class named as the type parameter. (Inherited from Object)

static bool IsClassA( const char * type ) const;

static bool IsClassA(string type);

@staticmethod
bool IsClassA(type: str)

SafeCast ​

SafeCast makes sure the input object is of a class that can be cast into spAttributeTessellation, and if this is the case, returns the object cast into spAttributeTessellation. (Inherited from Object)
