Mid-Air Drawing of Curves on 3D Surfaces in Virtual Reality

Rahul Arora, Karan Singh

Complex 3D curves can be created by directly drawing mid-air in immersive environments (Augmented and Virtual Realities). Drawing mid-air strokes precisely on the surface of a 3D v…

Thinking Outside the Lab: VR Size & Depth Perception in the Wild

Rahul Arora, Jiannan Li, Gongyi Shi +1

Size and distance perception in Virtual Reality (VR) have been widely studied, albeit in a controlled laboratory setting with a small number of participants. We describe a fully re…

Derandomizing Isolation Lemma for -free and -free Bipartite Graphs

Rahul Arora, Ashu Gupta, Rohit Gurjar +1

The perfect matching problem has a randomized NC algorithm, using the celebrated Isolation Lemma of Mulmuley, Vazirani and Vazirani. The Isolation Lemma states that giving a random…

Constraining Planetary Albedo of JWST Targets in the TESS bandpass, using TESS, HST and Spitzer Eclipse Depth Observations

Rahul Arora, Jayesh Goyal

Albedo is one of the important characteristics of hot Jupiter exoplanets. However, albedo constraints have been obtained for very few exoplanets. In this work, we present the TESS…

Quantifying the differences in transmission and emission spectra for hot irradiated gaseous exoplanet atmospheres: A comparison of 1D and 3D modeling using JWST

Rahul Arora, Liton Majumdar

Modeling the atmospheres of exoplanets is fundamental to understanding their atmospheric physics and chemical processes. While one-dimensional (1D) atmospheric models with 1D radia…

Designing Volumetric Truss Structures

Rahul Arora, Alec Jacobson, Timothy R. Langlois +6

We present the first algorithm for designing volumetric Michell Trusses. Our method uses a parametrization approach to generate trusses made of structural elements aligned with the…
