Changes since version 1.2.0¶

New Features¶

Per-frame camera playback in animated HTML export — AnimationRecording now snapshots the scene camera at each frame, and the animated export playback applies it via a shared applyCameraConfig helper, so set_camera() inside an animation loop is reflected in the exported animation.

Default 2D view now uses an orthographic camera — a space_dim=2 scene without an explicit camera kept the initial perspective camera, so flush(fit_camera=True) recentered a perspective camera and made the depth-layered grid and axes misalign. The viewer now switches to a top-down orthographic camera (see py/examples/viz/camera/fit_2d.py).
HTML export now honors the live scene camera — the export bootstrap dropped the 2D camera rectangle (xmin/xmax/ymin/ymax, uniform, border_px) and the 3D up vector, and animated figure exports always rendered in 3D. Exports now apply the full camera config through the shared applyCameraConfig helper.

Reorganized the viz examples — moved py/examples/viz/*.py into topic subfolders (camera/, plotting/, entities/, labels/, animation/, interaction/, scenes/, export/, styling/) and dropped the demo_ filename prefix, with the docs index updated to match.
