Interactive Boundary Detection for Automatic Definition of 2D Opacity Transfer Function
In computer assisted diagnostics nowadays, high-value 3-D visualization intake a supporting role to the traditional 2-D slice wise visualization. 3-D visualization may create intui...

Sample Based Visibility for Soft Shadows using Alias-free Shadow Maps
This paper introduces an accurate real-time soft shadow algorithm that uses sample based visibility. Initially, we present a GPU-based alias-free hard shadow map algorithm that ty...

Soft irregular shadow mapping: fast, high-quality, and robust soft shadows
We introduce a straightforward, robust, and efficient algorithm for rendering high-quality soft shadows in dynamic scenes. Each frame, points in the scene visible from the eye ar...

Automatic Detection and Segmentation of Ground Glass Opacity Nodules
Ground Glass Opacity (GGO) is defined as hazy increased attenuation within a lung that is not associated with obscured underlying vessels. Since pure (nonsolid) or mixed (partially...

Shadow maps and projective texturing in X3D
We propose a number of X3D extensions to enable shadows in the virtual worlds. Our higher-level extensions are an easy way to request shadows independently of their implementation...
