A fast and simple voxel traversal algorithm through a 3D space partition is introduced. Going from one voxel to its neighbour requires only two floating point comparisons and one floating point addition. Also, multiple ray intersections with objects that are in more than one voxel are eliminated. Introduction In recent years, ray tracing has become the algorithm of choice for generating high fidelity images. Its simplicity and elegance allows one to easily model reflection, refraction and…

Fast Ray-Tracing of Rectilinear Volume Data Using Distance Transforms

The paper discusses and experimentally compares distance based acceleration algorithms for ray tracing of volumetric data with an emphasis on the Chessboard Distance (CD) voxel traversal, which enables fast search of intersections between rays and the interpolated surface, further improving speed of the process.

Directed Safe Zones and the Dual Extent Algorithms for Efficient Grid Traversal during Ray Tracing

This paper presents two further improve ments to the proximity clouds method called the Directed Safe Zones DSZ and the Dual Extents DEs and shows that DSZs and DEs surpass the performance of both the proxim ity clouds and SEADS implementations.

GPU Ray Tracing using Irregular Grids

A spatial index structure to accelerate ray tracing on GPUs is presented, a flat, non‐hierarchical spatial subdivision of the scene into axis aligned cells of varying size that adapts the structure to complex primitive distributions, solving the "teapot in a stadium” problem.

Fast ray-tracing of rectilinear volume data

An algorithm for direct ray tracing of rectilinear grids is presented, which enables the implementation of surface rendering with subvoxel surface detection based on local interpolation, as well as different volume rendering techniques (color compositing, re-projection, maximum intensity projection).

Higher Performance Traversal and Construction of Tree-Based Raytracing Acceleration Structures

A fully SAM-based clustering heuristic is proposed which on average produces better performing BVHs compared to original agglomerative clustering and has subquadratic computational complexity in the number of primitives, which renders it usable in practical applications.

An Efficient Parametric Algorithm for Octree Traversal

This paper introduces a new top-down parametric method for octrees related to descent, that is, the selection of a child sub-voxel from the current one based on the parameter of the ray and comprises simple comparisons.

Ray tracing optimization utilizing projective methods

Results given for the regular grid- and quadtree-based techniques illustrate that even on single-processor machines it becomes viable to ray trace complex scenes in an affordable time, and are tested with scenes containing up to one million primitives.

This paper presents a high quality beam tracer that provides a robust and general antialiasing for polyhedral scenes and is entirely compatible with the usual improvements of classical ray tracing (spatial subdivisions or hierarchical bounding volumes).

Ray Tracing Optimization Utilizing Projective

New techniques for speeding up the ray tracing algorithm are presented, utilizing bounding rectangular extents around the primitives constituting the scene, which can be beneficial for many diferent types of primitives to be ray traced.
