Detailed Description

Caches data from the agent's rig, etc which is required for evaluating the ML skin deformer for a specific agent shape, and provides methods for evaluating the blend shape weights for a batch of agents.

bool GU_AgentMLSkinDeformerShapeCache::evaluate ( const UT_Array< UT_Span< const GU_Agent::Matrix4Type >> &  agent_world_poses,
UT_Array< GU_Agent::FloatType > &  agent_blend_shape_weights,
UT_StringHolder &  error_msg 
) const

Run the model for a batch of agents given their world space transforms. Outputs a flat list of the blend shape weights for each agent, in the order of the blendshape inputs for this agent shape (e.g. length is num_agent * numBlendShapes()).

bool GU_AgentMLSkinDeformerShapeCache::init ( const GU_AgentShapeLib::Shape &  agent_shape,
const GU_AgentDefinition &  agent_defn,
UT_StringHolder &  error_msg 
)

Pre-compute the required info for running the ML skin deformer on the given shape.

exint GU_AgentMLSkinDeformerShapeCache::numBlendShapes ( ) const

Returns the number of blendshape inputs for the shape.

void GU_AgentMLSkinDeformerShapeCache::setRigChannelValues ( UT_Span< GU_Agent::FloatType >  rig_channel_values,
const UT_Span< const GU_Agent::FloatType > &  blend_shape_weights 
) const

Marshal the blendshape weights into the rig's channel order, for a single agent.
