Detailed Description

Walk an Alembic tree to create Houdini geometry.

To convert an Alembic file to Houdini geometry, the code would look something like this:

GU_Detail   gdp;
GABC_GEOWalker      walker(gdp);
walker.setFrame(frame, fps);        // Specify the time sample
// Set any other parameters you might care about
walker.setBuildAbcPrim(true);
// Now, walker the Alembic file
if (!GABC_Util::walker(filename, walker))
    addError();

Push transform during traversal. If the walker is set to include the full transforms, the transform passed in will be combined with the current transform, otherwise the transform passed in will replace the transform state in the walker. The const_xform flag indicates whether the transform node is constant or not. The current state will be stashed in stash_prev and should be passed to popTransform().
