Computational study demonstrates real-time continuous collision detection between signed distance fields, indicating efficient time-of-impact calculation without mesh conversion.
Key Points
Develop a fast, robust method for direct continuous collision detection between pairs of complex signed distance fields without relying on dense sampling or triangle meshes.
Formulated continuous collision detection as an alternating spatio-temporal optimization problem.
Tracked time-of-impact by driving a sparse set of smartly sampled surface points along signed distance field tangent spaces.
Achieved real-time signed distance field collision queries, frequently executing within 1 ms on a single CPU core.
Maintained robust detection accuracy across highly detailed, non-convex geometric objects undergoing fast spinning motions.
