Gaze-dependent Ray Tracing
نویسندگان
چکیده
In this paper we introduce a method for acceleration of the real time ray tracing by using characteristic traits of visual perception. Ray tracing is a demanding rendering technique which is much slower than currently dominating scanline methods. Performance hit especially arise when we use huge amount of samples for anti-aliasing or other sample-based effects. We show how to decreases number of rays by increasing the perceptual size of selected pixels by using combination of eye tracking and the human gazedependent contrast sensitivity. Our study shows that number of processed pixels can be reduced three times without perceptually noticeable quality loss. As a result, we can greatly increase performance of ray tracing.

Utility of Gaze-contingent DOF Blur for Depth Perception
Copyright is held by the author/owner(s). ITS’13 , October 6–9, 2013, St. Andrews, UK. Abstract Depth-of-Field blur is a by-product of optical systems and its recreation can enhance the realism of images and convey information about size and distance. In this paper we present an approach to create a gaze-contingent DOF blur using pre-rendered scenes created with ray-tracing techniques. The appr...
متن کاملGaze Tracing in a Bounded Log-Spherical Space for Artificial Attention Systems
Human gaze is one of the most important cue for social robotics due to its embedded intention information. Discovering the location or the object that an interlocutor is staring at, gives the machine some insight to perform the correct attentional behaviour. This work presents a fast voxel traversal algorithm for estimating the potential locations that a human is gazing. Given a 3D occupancy ma...
متن کاملGaze-mouse coordinated movements and dependency with coordination demands in tracing
Eye movements have been shown to lead hand movements in tracing tasks where subjects have to move their fingers along a predefined trace. The question remained, whether the leading relationship was similar when tracing with a pointing device, such as a mouse; more importantly, whether tasks that required more or less gaze-mouse coordination would introduce variation in this pattern of behaviour...
متن کاملRay-tracing and Interferometry in Schwarzschild Geometry
Here, we investigate the possible optical anisotropy of vacuum due to gravitational field. In doing this, we provide sufficient evidence from direct coordinate integration of the null-geodesic equations obtained from the Lagrangian method, as well as ray-tracing equations obtained from the Plebanski’s equivalent medium theory. All calculations are done for the Schwarzschild geometry, which resu...
متن کاملVelocity Modeling in a Vertical Transversely Isotropic Medium Using Zelt Method
In the present paper, the Zelt algorithm has been extended for ray tracing through an anisotropic model. In anisotropic media, the direction of the propagated energy generally differs from that of the plane-wave propagation. This makes velocity values to be varied in different directions. Therefore, velocity modeling in such media is completely different from that in an isotropic media. The vel...
