thank you all of you. i try myself to finish my homework now. my teacher only gave some guides to do. i am begin to solve another home work. beside , i am a math student , not computer programming student.

. . . Can you line the dots? That's one polygon (a.k.a. Triangle) Regards. -------- M.D.V. ;) If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you Rating helpfull answers is nice, but saying thanks can be even nicer.

Do you still have the box your computer came in? :doh: You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists.

In your project settings, add the file Glaux.lib to your "import" box of the link section. Hope this helps. Happy programming!

Not higher than 1.1. Another standards body they should have not let Microsoft join. :mad: You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists.

I guess you probably mean convert; take a look at sprintf[^] and its variants.

This looks good, did you have a question about it?

Why don't you look it up by yourself ? Anyway, you could have a look at tutorial 6 (texture mapping) on this website[^] (you will probably need to have a look at the previous tutorials first). Cédric Moonen Software developer Charting control [v2.0] OpenGL game tutorial in C++

Then you can use DevIL or FreeImage (I think even GLUT is able to load bmp files but I'm not sure at all, I never used it). Did you look at these libraries ? If you are interested, you can also look at my second tutorial about OpenGL: it discusses resource management but it is probably it bit more higher level than what you are looking for.

You can check out the book by Carl DeBoor: "A Practical Guide to Splines". The programs in that book are in FORTRAN but can be easily rewritten in C++. I read that book in 1986 and learned a lot. Hope that can help you, too.

They are linker errors. See here. "One man's wage rise is another man's price increase." - Harold Wilson "Fireproof doesn't mean the fire will never come. It means when the fire comes that you will be able to withstand it." - Michael Simmons

You didn't say how you're writing your application but if you're using OpenCV's builtin GUI from HighGUI, Sareth is correct in how to handle it. Be advised though that the GUI interface that HighGUI supports is quite limited. To have any "reasonable" application other than small test cases, you probably want to explore other alternatives. You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists.
