Sorry, got nerd sniped: Isn't it usually the y coordinate that stands for the vertical axis? At least that's how I know 3D coordinate systems, with the z axis either increasing towards or away from the center, left handed vs right handed coordinate systems.
- jgilias 1y agoTowards or away from the center is the height, no? As in, you’re the bird at height Z observing the x-y plane under you, and the Z axis goes into you. Or away from you if you happen to be a mole under ground.
- arnsholt 1y agoIn GIS parlance, elevation is typically z coordinate. Which of x and y correspond to east-west and north-south varies from coordinate system to coordinate system, and is a bountiful source of stupid bugs (at least for me). But yeah, in 3D graphics z is usually distance from the camera I think.
- bmacho 1y agoProbably z pointing upwards is more common. https://en.wikipedia.org/wiki/Three-dimensional_space https://en.wikipedia.org/wiki/Three-dimensional_space https://en.wikipedia.org/wiki/Cartesian_coordinate_system#Three_dimensions https://en.wikipedia.org/wiki/Cartesian_coordinate_system#Th... https://www.google.com/search?udm=2&q=3d+coordinate+system https://www.google.com/search?udm=2&q=3d+coordinate+system
- fhd2 1y agoI see, fascinatingly inconsistent :D I somehow have the urge to popularise a coordinate system where the x axis represents elevation now.
