The proposed volumetric representation can be extended to handle more complex 3D shapes by incorporating advanced techniques for capturing intricate topologies and fine-grained details. One approach could involve increasing the spatial resolution and channel capacity of the feature volumes to accommodate more detailed information. By enhancing the resolution, the representation can capture finer details in the geometry and texture of objects. Additionally, incorporating hierarchical structures or adaptive grids can help in representing complex shapes with varying levels of detail. Utilizing multi-scale features and incorporating attention mechanisms can also improve the representation of intricate shapes by focusing on specific regions of interest. Furthermore, integrating shape priors or constraints based on the object category or shape characteristics can enhance the model's ability to handle diverse and complex 3D shapes effectively.
