HairPrimitive Class Reference

Detailed Description

This class represents the primitive of an X3DObject used for simulating hair in Softimage and can be accessed with X3DObject::GetActivePrimitive.

HairPrimitive provides access to the CRenderHairAccessor object which allows you to extract the render hair data from the primitive.

Member Function Documentation

bool IsA ( siClassID  in_ClassID ) const [virtual]

Returns true if a given class type is compatible with this API class.

in_ClassID class type.
true if the class is compatible, false otherwise.

Reimplemented from Primitive.

siClassID GetClassID ( ) const [virtual]

Returns the type of the API class.

The class type.

Reimplemented from Primitive.

HairPrimitive& operator= ( const HairPrimitive in_obj )

Creates an object from another object. The newly created object is set to empty if the input object is not compatible.

in_obj constant class object.
The new HairPrimitive object.
HairPrimitive& operator= ( const CRef in_ref )

Creates an object from a reference object. The newly created object is set to empty if the input reference object is not compatible.

in_ref constant class object.
The new HairPrimitive object.

Reimplemented from Primitive.

CRenderHairAccessor GetRenderHairAccessor ( LONG  in_nRequestedHairCount,
LONG  in_nChunksize = 10000,
double  in_time = DBL_MAX 
) const

Returns a render hair accessor for this primitive. The render hair accessor generates a renderable representation of a groomed hair primitive. The render hair is iterated over in chunks, rather than all at once, to avoid problems with excessive memory consumption.

in_nRequestedHairCount Maximum number of hairs desired. The actual number can be less depending on cut and density map settings.
in_nChunksize Number of hairs to generate on each iteration. By default the chunk size is set to 10000.
in_time Time (in frames) at which to get the accessor. The default value is DBL_MAX which means the current time in frames.
The new CRenderHairAccessor object.
Invalid if in_nRequestedHairCount is 0 or in_nChunksize is larger than in_nRequestedHairCount.
