The details from high-poly can be baked into texture maps. You convert high-poly to low-poly through retopology, or decimation.You convert low-poly to high-poly through sculpting, or Catmull-Clark subdivision.That's why you see so much about low-poly - with knowledge about low-poly topology the high-poly comes along. The problem with low-poly is topology, which has to follow some rules, so the shading looks right, the subdivision surfaces are right or the sculpts will be right.

low-polygon proxy geometries of high-poly ones - for rigging and animating.generated by some simulation, 3D scanning, etc.through control low-poly cages (subdivision surfaces).The problem is how you control such an enormous amount of vertices:

Highpoly is important to achieve superb surface detail.
