Enhanced Sphere Tracing
(The Eurographics Association, 2014)
In this paper we present several performance and quality enhancements to classical sphere tracing: First, we propose a safe, over-relaxation-based method for accelerating sphere tracing. Second, a method for dynamically ...
Real-Time Deformation of Subdivision Surfaces from Object Collisions
(The Eurographics Association, 2014)
We present a novel real-time approach for fine-scale surface deformations resulting from collisions. Deformations are represented by a high-resolution displacement function. When two objects collide, these offsets are ...
Real-time Local Displacement using Dynamic GPU Memory Management
(ACM, 2013)
We propose a novel method for local displacement events in large scenes, such as scratches, footsteps, or sculpting operations. Deformations are stored as displacements for vertices generated by hardware tessellation. ...
