Algorithm animation using shape analysis

Dierk Johannes, Raimund Seidel, Reinhard Wilhelm
2005 Proceedings of the 2005 ACM symposium on Software visualization - SoftVis '05  
We visualise the abstract execution of an algorithm instead of animating the algorithm for executions on concrete input data. Algorithms under consideration are imperative pointer-based algorithms.  ...  The most powerful method to accomplish this task automatically is shape analysis. However, the output of a shape analysis can get confusingly large and complex, and it may contain redundancy as well.  ...  Shape Analysis We want to visualise the abstract execution of an algorithm. Therefore, we need to compute invariants. The currently most powerful means to accomplish this task is shape analysis.  ...

Understanding the Role of Alternatives in Data Analysis Practices

Jiali Liu, Nadia Boukhelifa, James R. Eagan
2019 IEEE Transactions on Visualization and Computer Graphics  
Data workers are people who perform data analysis activities as a part of their daily work but do not formally identify as data scientists.  ...  Drawing upon these analyses and findings, we present a framework based on participants' 1) degree of attention, 2) abstraction level, and 3) analytic processes.  ...  Others used layering (P3, P5-6, P9) and animation (P2, P6). Some alternatives exist for the sole purpose of comparison.  ...

Modeling & Analysis

2003 NeuroImage  
Abstract Synopsis: A statistical model is used for the analysis of trial dependencies within auditory event-related fMRI experiments.  ...  This study was carried out not for stringent meta-analysis, but toward a 3D visualisation and data characterisation of their differential brain activations.  ...  Previous hippocampal shape studies often use volumetric representations [2,3]. We feel that surface-based techniques are more appropriate, since the surface of an object actually defines its shape.  ...
