Hierarchical operations about three-bvh-csg HOT 3 CLOSED

Open Question

• Should operations be added to each brush?
• Or should we require a separate "OperationBrush" that takes an operation, as well?
• Or a separate "wrapper" parent that describes the operation of the children to apply to the parent?

from three-bvh-csg.

API Considerations:

• Needs ability to insert a child before or after a specific brush for the sake of rearranging operation order.

Possible names:

• OperationBrush or HierarchicalBrush
• Group or PassthroughGroup

const rootBrush = new OperationBrush( box, material, ADD );

const childBrush = new OperationBrush( box, material, SUBTRACT );
childBrush.position.y = 0.5;
childBrush.scale.setScalar( 0.5 );
rootBrush.add( childBrush );

const result = evaluator.evaluateHierarchy( rootBrush ); // brush

// add "Group" or "PassthroughGroup" to enable operations passthrough and group transforms together
