Abstract

fetched live from OpenAlex

Point-based scanning is commonly used for 3D data acquisition. Applications can simply adopt a point cloud representation avoiding the computational complexity of connectivity construction. Despite many state-of-the-art algorithms discussing point cloud representation and rendering, research on dynamic point cloud visualization and interaction still lacks sufficient attention. We propose a time series hierarchy for interactive rendering of dynamic point-based 3D models. The synchronization of spatio-temporal attributes in the hierarchy makes this structure novel. A balanced hierarchy together with a compact quantization encoding scheme, results in higher precision, efficient memory usage and responsive user interaction. This representation provides smooth visualization of dense dynamic point-based models, in long sequences of 3D frames, at interactive frame rates and quality rendering, which can be displayed on regular desktops or mobile devices in either single-view or multi-view mode. A prototype system is implemented to validate the feasibility of our approach.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
