Detailed Description

IGeometryTangentCalculator calculates tangent vectors for geometry data objects. One corner field of texture coordinates must exist, as well as normals. The Tangents are placed into two corner fields called "Tangents" and "Bitangents". If any of these fields already exists, it is replaced by the new field.

Member Function Documentation

CalculateTangents() [1/2]

virtual void SimplygonSDK::ITangentCalculator::CalculateTangents ( IGeometryData *  geom )

pure virtual

Calculates the tangents of a geometry data object.

Parameters

geom	the geometry object receives new fields, as described in the class description.

CalculateTangents() [2/2]

virtual void SimplygonSDK::ITangentCalculator::CalculateTangents ( ISceneNode *  node )

pure virtual

Calculates the tangents of a tree of scene nodes (only the geometry nodes of course).

Parameters

node	is the scene node that will have itselfs and its childrens tangents calculated

GetClass()

virtual const char* SimplygonSDK::ITangentCalculator::GetClass ( )

virtual

GetClass returns the name of the class of the object.

Returns

the name of the actual class of the object, as a const char string

Reimplemented from SimplygonSDK::IObject.

GetTangentCalculatorType()

virtual rid SimplygonSDK::ITangentCalculator::GetTangentCalculatorType ( )

pure virtual

Gets the tangent calculator type, types listed in SimplygonSDK::TangentSpaceMethod

Returns

the current tangent calculator type

IsA()

virtual bool SimplygonSDK::ITangentCalculator::IsA ( const char *  type ) const

virtual

The IsA function returns true if the object is a or is a descendant of the class named as the type parameter

Parameters

type	is the name of the class to check if the object is, or is a descendant of

Returns

true if the object is of the specified class, false if not

Reimplemented from SimplygonSDK::IObject.

IsClassA()

static bool SimplygonSDK::ITangentCalculator::IsClassA ( const char *  type )

inlinestatic

The IsClassA function returns true if ITangentCalculator is a or is a descendant of the class named as the type parameter

Parameters

type	is the name of the class to check if the class is, or is a descendant of

Returns

true if the class is of the specified class, false if not

Definition at line 10642 of file SimplygonSDK.h.

SafeCast()

static ITangentCalculator* SimplygonSDK::ITangentCalculator::SafeCast ( IObject *  ptr )

inlinestatic

SafeCast makes sure the pointer is of a class that can be cast into a ITangentCalculator pointer, and if this is possible, returns the cast pointer.

Parameters

ptr	is the pointer to be cast into a ITangentCalculator pointer

Returns

a pointer to the ITangentCalculator object, if the cast can be made, and a NULL pointer otherwise

Definition at line 10655 of file SimplygonSDK.h.

SetTangentCalculatorType()

virtual void SimplygonSDK::ITangentCalculator::SetTangentCalculatorType ( rid  type )

pure virtual

Sets the tangent calculator type, types listed in SimplygonSDK::TangentSpaceMethod

Parameters

type	the desired tangent calculator type Value cannot be less than SG_TANGENTSPACEMETHOD_ORTHONORMAL. Value cannot be greater than SG_TANGENTSPACEMETHOD_ORTHONORMAL_LEFTHANDED.

SetTexCoordsSetId()

virtual void SimplygonSDK::ITangentCalculator::SetTexCoordsSetId ( rid  value )

pure virtual

The TexCoords field id to use for the tangent calculation. If set to -1, all texture coordinates will get corresponding tangent fields.

Parameters

value

the TexCoords set id
