Perspective › Examples
Webcam — Raw Stream
Data grid of index and color.
Live webcam luminance sampled into a Perspective table at 20fps (falls back to a placeholder image without a camera).

Data
Live webcam frames streamed into a Perspective table one pixel per row, and rendered back as real-time heatmaps, scatter plots and histograms.
Generated continuously in the browser by a JavaScript simulation streaming into a Perspective Table.
