Segmentation Assisted Object Distinction for Direct Volume Rendering
Ray Casting is a direct volume rendering technique for visualizing 3D arrays of sampled data. It has vital applications in medical and biological imaging. Nevertheless, it is inherently open to cluttered classification results. It suffers from overlapping transfer function values and lacks a sufficiently powerful voxel parsing mechanism for object distinction. In this work, we are proposing an ...
متن کاملCombining Rasterization and Ray Tracing Techniques to Approximate Global Illumination in Real-Time
This paper introduces a 3D rendering engine that combines rasterization and ray tracing techniques to approximate global illumination in real-time. Namely, direct and indirect diffuse illumination are generated with state of the art illumination techniques processed on the GPU, including a new sky lighting technique that we propose to simulate realistic ambient lighting for outdoor environments...
متن کاملOut-of-core Data Management for Path Tracing on Hybrid Resources
We present a software system that enables path-traced rendering of complex scenes. The system consists of two primary components: an application layer that implements the basic rendering algorithm, and an out-of-core scheduling and data-management layer designed to assist the application layer in exploiting hybrid computational resources (e.g., CPUs and GPUs) simultaneously. We describe the bas...
متن کاملHybrid ray tracing - ray tracing using gpu-accelerated image-space methods
In recent years, interactive ray tracing has become a reality, although mainly by using clustered workstations and sophisticated acceleration structures. On non-clustered computer architectures this is still not an easy task, especially when rendering animated scenes, even though the computation power of modern workstations is increasing rapidly. In this paper we propose known image-space rende...
متن کاملRendering Mixtures of Geometric and Volumetric Data
Many scientific problems require sampled functions and analytically defined objects to appear together in a single visualization. Volune rendering is a relatively new technique for visualizing sampled scalar functions of three spatial dimensions by computing 2D projections of a colored semi-transparent gel. This paper addresses the problem of extending volume rendering to handle polygonal objec...
