VD3D: Taming Large Video Diffusion Transformers for 3D Camera Control

International Conference on Learning Representations
Modern text-to-video synthesis models demonstrate coherent, photorealistic generation of complex videos from a text description. However, most existing models lack fine-grained control over camera movement, which is critical for downstream applications ...

V3D: Video Diffusion Models are Effective 3D Generators

arXiv.org
Automatic 3D generation has recently attracted widespread attention. Recent methods have greatly accelerated the generation speed, but usually produce less-detailed objects due to limited model capacity or 3D data.

3D-color video camera

2009 IEEE 12th International Conference on Computer Vision Workshops, ICCV Workshops, 2009
We introduce a design of a coded light-based 3D color video camera optimized for build up cost as well as accuracy in depth reconstruction and acquisition speed. The components of the system include a monochromatic camera and an off-the-shelf LED projector synchronized by a miniature circuit.

AC3D: Analyzing and Improving 3D Camera Control in Video Diffusion Transformers

Computer Vision and Pattern Recognition
Numerous works have recently integrated 3D camera control into foundational text-to-video models, but the resulting camera control is often imprecise, and video generation quality suffers.
