View Full Version : Edge Detection???

I performed the hidden line removal.

Now...I want to know how to extract the coordinate values of starting point and

end point of the visible edge.

Maybe...I have to read the frame buffer and

depth buffer...

I knew how to read these buffers...

My problem is following..

Whether the read pixel is ending point of

visible edge????

Please give me the algorithm

about the edge detection.

Maybe you could use the feedback mode to get the 3D coordinates.
