Terrain Sketches Made-up landscapes rendered as maps: hillshade, contours and colour ramps. https://alder.sanriodevgroup.org/ 2024-07-24T12:00:00Z Terrain Sketches Timeouts and budgets for tileshttps://alder.sanriodevgroup.org/notes/timeouts-and-budgets/2024-07-12T16:00:00Z2024-07-24T16:00:00ZLarge renders are cut into tiles with a time budget each. A tile that overruns is rendered at half resolution and marked for a second pass, so a print never waits on one slow corner. Contours at a fixed stephttps://alder.sanriodevgroup.org/maps/contours-every-step/2024-06-21T12:00:00Z2024-06-26T12:00:00ZThin lines where the height crosses a multiple of the step. Colour ramps for elevationhttps://alder.sanriodevgroup.org/maps/colour-ramps-for-elevation/2024-05-11T22:00:00Z2024-05-11T22:00:00ZGreen low, brown high, white on top. Hillshade from a heightmaphttps://alder.sanriodevgroup.org/maps/hillshade-from-a-heightmap/2024-04-20T20:00:00Z2024-05-03T20:00:00ZLight from the north-west, like most printed maps. Erosion, faked cheaplyhttps://alder.sanriodevgroup.org/maps/erosion-faked-cheaply/2024-03-12T18:00:00Z2024-03-12T18:00:00ZBlurring the lowlands a little makes valleys. Tile sizeshttps://alder.sanriodevgroup.org/notes/tile-sizes/2024-02-17T20:00:00Z2024-02-17T20:00:00Z256 pixels is the web map convention; for prints, 1024-pixel tiles waste less time on seams.
