Constructor & Destructor Documentation

GU_MotionClipRO::GU_MotionClipRO ( const GU_Detail gdp,
UT_WorkBuffer err_msg,
bool  can_evaluate = true,
GU_MotionClipInfo clipinfo = nullptr 

clipinfo will override the gdp's clipinfo detail attribute

Member Function Documentation

void GU_MotionClipRO::computeLocalTransforms ( fpreal  time,
UT_Array< GU_AgentXformD > &  result 

This computes the local transforms of each joint at the given time. The ith element defines represents the ith joint in the topology detail. getJointIndex can be used to check this

Definition at line 80 of file GU_MotionClip.h.

void GU_MotionClipRO::evaluate ( fpreal  time,
GU_Detail result,
const GA_PointGroup result_pts = nullptr,
const GA_PointGroup topology_pts = nullptr,
const GA_AttributeFilter extra_attribs_to_unpack = nullptr,
GU_MotionClipEndBehavior  left_end_behavior = GU_MotionClipEndBehavior::Clamp,
GU_MotionClipEndBehavior  right_end_behavior = GU_MotionClipEndBehavior::Clamp 

This will compute the frame at the given time, and then copy the P+transform attributes of the ith point in topologyPts into the ith point in resultPts.

It will also include whatever extra attribs you request as long as there is no current active GU_MotionClipBuilder

resultPts and topologyPts must correspond to the same points in their respective geometries, in the same order.

Definition at line 63 of file GU_MotionClip.h.

const GA_PointGroup* GU_MotionClipRO::getJointGroup ( GOP_Manager gop,
const UT_StringHolder pattern 
) const

Returns a point group of the topology detail based on the given pattern

exint GU_MotionClipRO::getJointIndex ( const UT_StringHolder joint_name) const

Returns the index of the given joint name within the topology detail

Definition at line 89 of file GU_MotionClip.h.

const GU_Detail* GU_MotionClipRO::getSample ( fpreal  time) const

returns the sample at time, or nullptr if not found

const UT_Array<fpreal>& GU_MotionClipRO::getSampleTimes ( )

Definition at line 117 of file GU_MotionClip.h.

void GU_MotionClipRO::getTopology ( fpreal time,
GU_Detail dest,
const GA_AttributeFilter skip = nullptr 

Appends the unpacked toplogy geometry to dest

bool GU_MotionClipRO::hasTopology ( ) const

Definition at line 51 of file GU_MotionClip.h.

bool GU_MotionClipRO::isInitialised ( ) const

returns false if there was an error during initialization
