Assets and Transforms

Assets and Transforms

A recipe's assets — the objects in a scene — are stored as a tree: branch nodes carry position, scale, and rotation; leaf nodes are objects with a material and a shape. Find an asset with piAssetSearch rather than a literal name — see Recipe Workflow for a short example. For the full API — node types, world vs. local coordinates, copying, grafting, and motion — see the iset3d-assets-and-transforms skill in the ISET3D repository.

Tutorials

Start here:

• t_assets.m — the asset tree, piAssetSearch, and basic transforms.

Going deeper:

• t_assetsCopy.m — copy an object to multiple positions using instance nodes.
• t_assetsMotion.m — add a motion transform to one asset and render.
• t_assetsSubtree.m — remove and graft back a subtree of the asset tree.
• t_assetsWorldTrans.m — compute positions and rotations in world coordinates, accounting for parent nodes.

Manual run (marked % SkipFile — excluded from the automated tutorial smoke test as interactive walkthroughs, but still useful):

• t_assetsViewPoint.m — place the camera at one object and look toward another.
• t_assetsWorldRot.m — object- vs. world-coordinate rotation walkthrough.
