// a very simple example: render a triangle in S3 using HyperRogue engine

// compile with: mymake rogueviz/sample.cpp

// run HyperRogue with: ./hyper -geo 120c -canvas 0 -noplayer
// press End to move forward (initially the camera is in the center of the triangle so you don't see it)

// (120c sets spherical geometry (120-cell) and -canvas 0 makes the world empty)
