Fabrication-Aware Design with Performative Criteria

Yuliy Gennadievich Schwartzburg

Artists and architects often need to handle multiple constraints during design of physical constructions. We define a performative constraint as any constraint on design that is tied to the performance of the model--either during fabrication, construction, ...

High-contrast Computational Caustic Design

Mark Pauly, Andrea Tagliasacchi, Yuliy Gennadievich Schwartzburg, Romain Pierre Testuz

We present a new algorithm for computational caustic design. Our algorithm solves for the shape of a transparent object such that the refracted light paints a desired caustic image on a receiver screen. We introduce an optimal transport formulation to esta ...

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 ...

Architectural Caustics — Controlling Light with Geometry

Mark Pauly

Caustics are captivating light patterns created by materials bundling or diverting light by refraction or reflection. We know caustics as random side effects, appearing, for example, at the bottom of a swimming pool. In this paper we show that it is possib ...

Caustic Art

Mark Pauly

The computation of caustics created by reflection or refraction of light is a well-studied problem in computer graphics. This paper investigates the inverse problem: Given a greyscale intensity image, find the shape of a surface that will cast a caustic th ...

Goal-Based Caustics

Wenzel Alban Jakob, Marios Papas

We propose a novel system for designing and manufacturing surfaces that produce desired caustic images when illuminated by a light source. Our system is based on a nonnegative image decomposition using a set of possibly overlapping anisotropic Gaussian ker ...

Online loop closure for real-time interactive 3D scanning

We present a real-time interactive 3D scanning system that allows users to scan complete object geometry by turning the object around in front of a real-time 3D range scanner. The incoming 3D surface patches are registered and integrated into an online 3D ...

Ray tracing study for non-imaging daylight collectors

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Friedrich Linhart, Stephen Wittkopf, Raphaël Compagnon, Lars Oliver Grobe

This paper presents a novel method to study how well non-imaging daylight collectors pipe diffuse daylight into long horizontal funnels for illuminating deep buildings. Forward ray tracing is used to derive luminous intensity distributions curves (LIDC) of ...

Experimental and simulation-based approaches to assess bidirectional properties of complex fenestration systems

Marilyne Andersen

A serious effort has been made in developing accurate and efficient bidirectional goniophotometric devices for detailed studies of Complex Fenestration Systems, capable of measuring BTDFs and/or BRDFs in an appropriate way. The existing instruments are alm ...

Splines and wavelets for image warping and projection

Stefan Horbelt

This thesis investigates advanced signal processing concepts and their application to geometric processing and transformations of images and volumes. In the first part, we discuss the class of transformations that project volume data onto a plane using par ...
