In spite of their mysterious sounding name glenz vectors are simply 3D objects made of polygons or more precisely triangles. Half of these triangles are white while the other half is coloured and above all transparent. If you think that my words are not clear enough then I hope that the following picture will prove helpful.
Appeared in the early 90s, glenz vectors are quite simple looking shapes. Well to be honest it all depends on coders skills since they first need to think about how to build them (out of triangles remember) before they manage to make them move smoothly all over the screen.
Most of the time glenz vectors are of decent size, rarely big and on very few occasions they will simply amaze you :
- Like the 2 merging glenz vectors seen in the 2003 Illusion demo by Dune. They look great and keep rotating while mixing together.
- This other glenz vector is impressive at it is announced to be made up of 192 polygons while usually most effects like this are « only » made of a dozen triangles. Taken from the amazing 1999 Virtual Escape demo by Equinox.
What I like most with this effect is when a glenz vector starts morphing that is to say changes shapes while still moving on screen. Then a pyramid can become a sort of ball or a stretched out object.
Now let’s have a look at the groovy glenz vectors seen in the If Pigs Could Fly demo :
