ExplicitPlacement Class Reference

#include "steam/mobject/explicitplacement.hpp"

Description

Special kind of Placement, where the location of the MObject has been nailed down to a fixed position.

The Session maintains a special list of Placements, which actually is a snapshot of all Session contents fixed and reduced to simple positions. This so called Fixture contains only ExplicitPlacement objects and is processed by the Builder to create the render engine node network.

Deprecated:

2025/4 while we need a marker for an explicit placement, implementing this as a subclass is the dog-no-wag-tail anti pattern. Inheritance indicates a contract, but should not be abused to mark properties.
