Constructor & Destructor Documentation

GEO_PrimChannel::GEO_PrimChannel ( GEO_Detail d,
GA_Offset  offset = GA_INVALID_OFFSET 

NOTE: The constructor should only be called from subclass constructors.

GEO_PrimChannel::~GEO_PrimChannel ( )

NOTE: The destructor should only be called from subclass destructors.

Definition at line 34 of file GEO_PrimChannel.h.

Member Function Documentation

GA_Size GEO_PrimChannel::appendVertex ( GA_Offset  ptoff)

Append a vertex. For the channel primitive, Vertices are used to refer to a point which uses the underlying channel.

SYS_FORCE_INLINE void GEO_PrimChannel::assignNewDataId ( )

Definition at line 79 of file GEO_PrimChannel.h.

UT_Vector3 GEO_PrimChannel::baryCenter ( ) const

Return the center of the primitive. This defaults to the center of the bounding box. A better approximation might be the average value of the vertex positions (which could be different).

Reimplemented from GEO_Primitive.

static GEO_PrimChannel* GEO_PrimChannel::build ( GA_Detail gdp,
fpreal  value,
const UT_SharedPtr< CL_SimpleChannel > &  channel 
static GA_PrimitiveFamilyMask GEO_PrimChannel::buildFamilyMask ( )

Register intrinsic attributes.

Definition at line 112 of file GEO_PrimChannel.h.

SYS_FORCE_INLINE void GEO_PrimChannel::bumpDataId ( )

Definition at line 82 of file GEO_PrimChannel.h.

UT_Vector3 GEO_PrimChannel::computeNormal ( ) const

Return a normal vector for the primitive.

Implements GEO_Primitive.

UT_Vector3D GEO_PrimChannel::computeNormalD ( ) const

Implements GEO_Primitive.

GEO_Primitive* GEO_PrimChannel::copy ( int  preserve_shared_pts = 0) const

Though not strictly required (i.e. not pure virtual), these methods should be implemented for proper behaviour.

Reimplemented from GEO_Primitive.

void GEO_PrimChannel::copyPrimitive ( const GEO_Primitive src)

Implements GEO_Primitive.

void GEO_PrimChannel::copySubclassData ( const GA_Primitive source)

Copy all subclass data from source to this.

The vertex lists of source and this must already be equivalent in some manner, though possibly referring to different vertices.

If some subclass data is dependent on the vertex list contents, (such as GEO_PrimPolySoup::myPolygonVertexList), it should be mapped based on the correspondence between the two. GEO_PrimPolySoup is currently the only primitive type with this sort of dependence, so it's probably best not to add more.

NOTE: This must be safe to call on different primitives in parallel at the same time.

Reimplemented from GA_Primitive.

GA_DereferenceStatus GEO_PrimChannel::dereferencePoint ( GA_Offset  point,
bool  dry_run = false 

Before a point is deleted, all primitives using the point will be notified. The method should return "false" if it's impossible to delete the point. Otherwise, the vertices should be removed.

Implements GA_Primitive.

GA_DereferenceStatus GEO_PrimChannel::dereferencePoints ( const GA_RangeMemberQuery pt_q,
bool  dry_run = false 

Implements GA_Primitive.

int GEO_PrimChannel::detachPoints ( GA_PointGroup grp)

Implements GEO_Primitive.

bool GEO_PrimChannel::evaluatePointRefMap ( GA_Offset  result_vtx,
GA_AttributeRefMap hlist,
fpreal  u_unit,
fpreal  ,
uint  du,
) const

Implements GEO_Primitive.

int GEO_PrimChannel::evaluatePointV4 ( UT_Vector4 pos,
float  u,
float  v = 0,
unsigned  du = 0,
unsigned  dv = 0 
) const

Evaluate the position for the given parametric coordinates (with the given derivatives). Return 0 if successful, or -1 if failure. The default implementation returns {0,0,0,0};

Reimplemented from GEO_Primitive.

bool GEO_PrimChannel::getBBox ( UT_BoundingBox bbox) const

Compute the bounding box of the primitive. Return 0 if unable to compute bounds (1 on successful computation). This function should always initialize bbox, even if returning false, in which case, the bbox->isValid() may be false, representing an empty bounding box. This function should also not use any initial value of bbox, so it does not need to be initialized beforehand.

Implements GEO_Primitive.

UT_SharedPtr<CL_SimpleChannel> GEO_PrimChannel::getChannel ( )
UT_SharedPtr<const CL_SimpleChannel> GEO_PrimChannel::getConstChannel ( ) const
SYS_FORCE_INLINE int64 GEO_PrimChannel::getDataId ( ) const

Definition at line 76 of file GEO_PrimChannel.h.

const GA_PrimitiveJSON* GEO_PrimChannel::getJSON ( ) const

This method returns the JSON interface for saving/loading the primitive If the method returns a NULL pointer, then the primitive will not be saved to geometry files (and thus cannot be loaded).

Implements GA_Primitive.

bool GEO_PrimChannel::isDegenerate ( ) const

Is the primitive degenerate.

Implements GA_Primitive.

bool GEO_PrimChannel::loadChannel ( UT_JSONParser p,
const GA_LoadMap map 

Save/Load properties to a JSON stream

bool GEO_PrimChannel::loadVertexArray ( UT_JSONParser p,
const GA_LoadMap map 

Save/Load properties to a JSON stream

void GEO_PrimChannel::normal ( NormalComp output) const

Implements GEO_Primitive.

Reimplemented in GU_PrimChannel.

void GEO_PrimChannel::normal ( NormalCompD output) const

Implements GEO_Primitive.

Reimplemented in GU_PrimChannel.

void GEO_PrimChannel::reverse ( )

Reverse the order of vertices.

Implements GEO_Primitive.

bool GEO_PrimChannel::saveChannel ( UT_JSONWriter w,
const GA_SaveMap map 
) const

Save/Load properties to a JSON stream

bool GEO_PrimChannel::saveChannelProperties ( UT_JSONWriter w) const
bool GEO_PrimChannel::saveVertexArray ( UT_JSONWriter w,
const GA_SaveMap map 
) const

Save/Load properties to a JSON stream

void GEO_PrimChannel::stashed ( bool  beingstashed,
GA_Offset  offset = GA_INVALID_OFFSET 

Stash (deactivate) or unstash (reactivate) the primitive.

Stashing a primitive will set its offset to that specified, typically GA_INVALID_OFFSET. Primitives are only stashed as part of clearing a detail, so there is no need to explicitly deallocate vertices. It is safe to delete a stashed primitive.

Unstashing a primitive will re-register that primitive with its parent detail at the specified offset (or a new offset if GA_INVALID_OFFSET).

Reimplemented from GA_Primitive.
