Abstract

fetched live from OpenAlex

Point sampled geometry has recently gained significant interest due to the tremendous advances in the technology of 3D scanning and the representational simplicity afforded by avoiding any need for explicit connectivity information. Their use in creating high-quality rendered images is however still limited. Till date, most renderings of point sampled surfaces use the Phong illumination model. In this paper we consider the rendering of point sampled surfaces with both diffuse and specular material properties under distant illumination, as specified using an environment map. For this, we have combined two of the earlier works for continuous surfaces, spherical harmonic representations of irradiance environment maps and glossy reflection, and programmed it on the GPU using vertex and fragment shaders. This hardware accelerated implementation has been incorporated into a public domain point based renderer enabling us to efficiently produce high quality images of point sampled geometry

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.
