| This demonstrates the animation and image painting abilities of VRML. The climber is made of very simple geometric
units (a sphere, a cone, and some cylinders), but the use of appropriate colours, painted or photographic images,
and textures can give a surprising degree of reality. This unit is used for a vertical axis in the orientation axes as it unequivocally demonstrates the effect of gravity in contrast to static alternatives which I decided were open to misinterpretation - a plumb bob would indicate down, but it could be mistaken for a balloon, which would indicate up. The North arrow is wholly conventional; the East cross is a reintroduction of a motif common in 18th century maps. |
