By routing text-to-geometry interactions across matched abstraction scales rather than flattening everything into one representation, you can build faster, more accurate 3D models that understand both coarse structure and fine details.
ELSA3D is a unified 3D foundation model that improves how language and 3D geometry interact by using 'anchor tokens' to match text concepts with the right level of geometric detail. Instead of treating all information equally, it routes language features to specific scales of 3D structure, making the model both more efficient and more accurate for generating and understanding 3D objects.
