mesh objects are made out of triangles, this tool demonstrates how meshes are basically made of. im sure someone might find it useful.

1. create a sphere prim ( scale < 0.15, 0.15, 0.15 >, add alpha, glow, fullbright, bump, shiny how you like ) and add script "Vertex" and "Triangle Detailer" to it. set object name to "Vertex".

2. create a sphere prim ( scale < 0.01, 0.01, 0.01 >, add alpha, glow, fullbright, bump, shiny, texture how you like ) and add script "Triangle" to it. set object name to "Triangle".

3. add the Triangle object to the Vertex object.

4. shift-copy the Vertex object 2 times, so you have 3 of them, move them to form an imaginary Triangle, then touch these 3 one after another, it will create a Triangle between these, shift-copy more Vertex objects and repeat touching them.
