Abstract

fetched live from OpenAlex

Efficient online visualization of three-dimensional (3-D) textured models is essential for a variety of applications including not only games and e-commerce, but also heritage and medicine. To visualize 3-D objects online, it is necessary to quickly adapt both mesh and texture to the available computational or network resources. Earlier research showed that after reaching a minimum required mesh density, high-resolution texture has more impact on human perception than a denser mesh. Given limited bandwidth, an important issue is how to extract features that best represent the original object, and how to allocate resources between mesh and texture data to achieve optimal perceptual quality. In this paper, we propose a textured mesh (TexMesh) model, which applies scale-space analysis and perceptual evaluation to extract 3-D features for textured mesh simplification and transmission. Texture data is divided into fragments to facilitate quality and bandwidth adaptation. Texture quality assignment is based on feature point distribution. Online transmission is based on statistics gathered during preprocessing, which are stored in a priority queue and lookup tables. Quality of service requested by a client site can be met by applying an efficient adaptive algorithm to ensure optimal use of the specified time and available bandwidth, and at the same time preserving satisfactory quality. Our TexMesh framework integrates feature extraction, mesh simplification, texture reduction, bandwidth adaptation, and perceptual evaluation into a multiscale visualization framework.

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.
