Intersection of two line segment in 3 dimensions

20 May 2012 - 06:21 AM

Hello to all users,
I have a simple question for more of us.
I am developing a project and I need to calculate if two line segment intersect.
is there any mathematical way to do that?
With more details:
Segment_1 is from point A to point B, where A=(X_a, Y_a, Z_a) and B=(X_b, Y_b, Z_b)
Segment_2 is from point C to point D, where C=(X_c, Y_c, Z_c) and D=(X_d, Y_d, Z_d)
Is there any condition between the points coordinates that determines if the two segments intersect?
Thanks in advance

Intersection of two CONVEX polyhedrons

17 April 2012 - 04:00 AM

Hello to all users,
I need to calculate the intersection of two given CONVEX 3D polyhedrons. How can I do that?
I know the x,y,z, coordinates of each vertex and also the triangles list that I use to draw each polyhedron.
Any help would be very very appreciated.
With regards,
Dimitris

Save a win32 project window as an image

07 April 2012 - 04:24 PM

Hello to all users,
I am using visual studio 2010 and I have a simple win32 project (that reads a polyhedron from a file and shows it).
My problem is that in that project I want to save the opened window (that shows the polyhedron) as an image.
Or to say it more general, how can I save the opened window as an image (for example as jpp, bmp etch)?
Attention, that I use win32 project, NOT windows form application.
Best regards,
Dimitris
