Hi
I want to make shadow volumes with OpenGL,
But i don't know how i can receive positions of edge points of a object and How i can understand where do arrive the length of a line with have linear equation.
I read a lot of instruction but i don't understand.
please help me...:icon_rolleyes:

The shadow volume technique creates sharp, per-pixel accurate shadows from point, spot, and directional lights. This is a very complicated subject. Also you don't provide details about "Shadow" issue ?

This is an openGL url: http://www.opengl.org/discussion_boards/ , this url is helpful. :)
