Abstract
We describe an auto-calibrated 3D perspective-corrected spherical display that uses multiple rear projected pico-projectors. The display system is auto-calibrated via 3D reconstruction of each projected pixel on the display using a single inexpensive camera. With the automatic calibration, the multiple-projector system supports a seamless blended imagery on the spherical screen. Furthermore, we incorporate head tracking with the display to present 3D content with motion parallax by rendering perspective-corrected images based on the viewpoint. To show the effectiveness of this design, we implemented a view-dependent application that allows walk-around visualization from all angles for a single head-tracked user. We also implemented a view-independent application that supports a wall-papered rendering for multi-user viewing. Thus, both view-dependent 3D VR content and spherical 2D content, such as a globe, can be easily experienced with this display.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
