Raster Reprojection I

Full Screen

You can reproject equirectangular raster tiles onto a Canvas with an orthographic projection. You can also combine the Canvas with SVG raster tiles.

Toggle the checkbox to see what it looks like with and without a clipping mask.

You can achieve significant performance improvements with WebGL. See Raster Reprojection II for a demonstration.
