3D Points Projection – SVD/PCA
Drag/zoom in 3D. Use sliders to pick a projection axis (θ, φ) or Reset for the 1st eigencomponent.
Use the Rotation (R) slider to orbit around the projection axis for different camera views.
The yellow ball shows a side view perpendicular to the projection axis (gray line).
The 2D plot at bottom-left displays what this camera sees, with points projected along the axis.
