bool openvdb_houdini::GEOvdbApply ( GEO_PrimVDB &  vdb,
OpT &  op,
bool  makeUnique = true 
)
inline

If the given primitive's grid resolves to one of the listed grid types, invoke the functor op on the resolved grid.

Returns
true if the functor was invoked, false otherwise

If makeUnique is true, deep copy the grid's tree before invoking the functor if the tree is shared with other grids.

OPENVDB_HOUDINI_API bool openvdb_houdini::isLogForwarding ( OP_OpTypeId  )

Return true if OpenVDB messages logged by operators of the given type are forwarded to the Houdini error manager.

OPENVDB_HOUDINI_API openvdb::CoordBBox openvdb_houdini::makeCoordBBox ( const UT_BoundingBox &  ,
const openvdb::math::Transform &   
)

Construct an index-space CoordBBox from a UT_BoundingBox.

OPENVDB_HOUDINI_API void openvdb_houdini::pointDataGridSpecificInfoText ( std::ostream &  ,
const openvdb::GridBase  
)

If the given grid is a PointDataGrid, add node specific info text to the stream provided. This is used to populate the MMB window in Houdini versions 15 and earlier, as well as the Operator Information Window.

OPENVDB_HOUDINI_API bool openvdb_houdini::pointInPrimGroup ( GA_Offset  ptnOffset,
GU_Detail &  ,
const GA_PrimitiveGroup &   
)

Return true if the point at the given offset is referenced by primitives from a certain primitive group.

OPENVDB_HOUDINI_API void openvdb_houdini::populateMetadataFromHoudini ( openvdb::points::PointDataGrid &  grid,
const GU_Detail &  detail,
const WarnFunc warnings = [](const std::string &){} 
)

Populate VDB Points grid metadata from Houdini detail attributes.

Parameters
gridgrid to be populated with metadata
detailGU_Detail to extract the detail attributes from
warningslist of warnings to be added to the SOP
OPENVDB_HOUDINI_API GU_PrimVDB* openvdb_houdini::replaceVdbPrimitive ( GU_Detail &  gdp,
GridPtr  grid,
GEO_PrimVDB &  src,
const bool  copyAttrs = true,
const char *  name = nullptr 
)

Replace an existing VDB primitive with a new primitive that contains the given grid.

Returns
the newly-created VDB primitive.
Parameters
gdpthe detail to which to add the primitive
gridthe VDB grid to be added
srcreplace this primitive with the newly-created primitive
copyAttrsif true, copy attributes and group membership from the src primitive
nameif non-null, set the new primitive's name attribute to this string; otherwise, if copyAttrs is true, copy the name from src
Note
This operation clears the input grid's metadata.
OPENVDB_HOUDINI_API void openvdb_houdini::startLogForwarding ( OP_OpTypeId  )

Start forwarding OpenVDB log messages to the Houdini error manager for all operators of the given type.

Typically, log forwarding is enabled for specific operator types during initialization of the openvdb_houdini library, and there's no need for client code to call this function.

This function has no effect unless OpenVDB was built with log4cplus.

Note
OpenVDB messages are typically logged to the console as well. This function has no effect on console logging.

OPENVDB_HOUDINI_API void openvdb_houdini::stopLogForwarding ( OP_OpTypeId  )

Stop forwarding OpenVDB log messages to the Houdini error manager for all operators of the given type.

Typically, log forwarding is enabled for specific operator types during initialization of the openvdb_houdini library, and there's no need for client code to disable it.

This function has no effect unless OpenVDB was built with log4cplus.

Note
OpenVDB messages are typically logged to the console as well. This function has no effect on console logging.
