چکیده
In the real world, light sources emit photons which normally travel in straight lines until they interact with a surface or a volume. When a photon encounters a surface, it may either be absorbed, reflected or transmitted. Some of these photons may hit the retina of an observer where they are converted into a signal which is then processed by the brain, thus forming an image. Similarly, photons may be caught by the sensor of a camera. In either case, the image is a 2D representation of the environment.

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 کاملSpatial Relationship between Mandibular Third Molars and Inferior Alveolar Nerve using a Volume Rendering Software
Precise localization of the third molars in relation to the inferior alveolar nerve canal is critical from a clinical point of view and strongly affects the surgical treatment outcome. Recently, by using three-dimensional modeling software, the relationship of third molar root apices and inferior alveolar nerve canal can be better understood. In this study, the spatial relationship of two surgi...

متن کاملA Generic Rendering System
We describe the software architecture of a rendering system that follows a pragmatic approach to integrating and bundling the power of different lowlevel rendering systems within an object-oriented framework. The generic rendering system provides higher-level abstractions to existing rendering systems and serves as a framework for developing new rendering techniques. It wraps the functionality ...
