Ray Tracing for Curves Primitive
نویسندگان
چکیده
The Curves primitive defined in RenderMan is useful for modelling and rendering ribbonlike objects. This paper gives a simple framework for ray-curve intersection tests in ray tracing, and provides concrete details for one form of the primitive. The form is especially important for fine objects such as hair and fur.

Ray-Box Culling for Tree Structures
Ray-primitive intersection tests are the most important operations in ray tracing. The ray-box culling algorithm was presented to accelerate these intersection tests on grid structures, but this algorithm has not been widely used due to the poor ray traversal performance of the grid structures themselves. In this paper, we demonstrate how to apply this algorithm to tree structures and investiga...
متن کاملFast Ray Sorting and Breadth-First Packet Traversal for GPU Ray Tracing
We present a novel approach to ray tracing execution on commodity graphics hardware using CUDA. We decompose a standard ray tracing algorithm into several data-parallel stages that are mapped efficiently to the massively parallel architecture of modern GPUs. These stages include: ray sorting into coherent packets, creation of frustums for packets, breadth-first frustum traversal through a bound...
متن کاملStack Implementation on Programmable Graphics Hardware
We present a technique that allows the implementation of a stack on programmable graphics hardware, using textures and fragment shaders. This development enables a whole new class of GPU algorithms, including recursive functions on complex data structures. Kd-tree traversal for ray tracing is demonstrated as an application. The traversal core was integrated into a purely GPU based photorealisti...
متن کاملX-ray tracing using Geant4
We describe an extension to the Geant4 software package that allows it to be used as a general purpose X-ray tracing package. We demonstrate its use by building a model of the X-ray optics of the XMM-Newton, calculating its effective area, and comparing the results with the published calibration curves.
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...
