Automatic Generation of Constructable Brick Sculptures

Romain Pierre Testuz, Yuliy Gennadievich Schwartzburg, Mark Pauly

Fabrication of LEGO models in large scale requires careful pre-planning to produce constructable and stable models. We propose a system that, starting with a voxelization of a 3D mesh, merges voxels to form larger bricks, and then analyzes and repairs stru ...

Controlling caustics

Mark Pauly

Caustics are captivating light patterns created by materials focusing or diverting light by refraction or reflection. We know caustics as random side effects, appearing, for example, at the bottom of a swimming pool, or generated by many glass objects, lik ...

Factored Facade Acquisition using Symmetric Line Arrangements

Duygu Ceylan, Mark Pauly, Hao Li

We introduce a novel framework for image-based 3D reconstruction of urban buildings based on symmetry priors. Starting from image-level edges, we generate a sparse and approximate set of consistent 3D lines. These lines are then used to simultaneously dete ...
