I am OpenGl beginner. I would like to ask a question. If I have a group of points which describe sth(e.g. human). Do anyone knows some alogrithms can helps to generate the object using those points? Or, using the traditional method, draw many and many triangles to create the human.
Check out Hughes Hoppe's page http://research.microsoft.com/~hoppe/
Scroll down the page a bit to find "Surface reconstruction from unorganized points".
Also, check out all his other papers. Lots of good reading there!
