animation in opengl
-
I am trying to animate my object like below, the object should move back and forth, but with this i can't see the movement. please tell me whats going wrong in this code below. Thanks Sujan [code]
// TODO: Add your command handler code here
CDC* pDC = GetDC();
wglMakeCurrent(pDC->m_hDC, m_hrc);
transObj2[0]=transObj2[0] - 40.0f;
Invalidate();
Sleep(5000);
transObj2[0]=transObj2[0] + 40.0f;
Invalidate();
Sleep(5000);
wglMakeCurrent(NULL,NULL);[/code]
But there's no drawing code! OpenGL maintains the positions of your vertices and polygons for 1 frame. In this sample you never tell GL anything, except the HDC of the window you'd like it to draw in. Even this looks a little suspicious. Generally, one would get the HDC of a static control and throw that to GL. You've not draw the objects at all, hence you'll not see them drawn in different positions. Go lookup Nehe OpenGL tutorials. Or even 'Rotate Triangle openGL'...

YOUR REWARD FOR YELLING IS NOTHING! That's right, I'm going to give you nothing. Bugger off!

Sleep will lock all update/refresh to the display. For example, use glutTimerFunc to update your scene transformations and draw your scene at fixed intervals. Have a look at : 3.050 How can I perform animations with GLUT?[^] for a start.
Watched code never compiles.

You might like to remove the obscenity from the above.

Sleep(5000);That call to
Sleep()prevents your code from responding to the nextWM_PAINTmessage. You need to run in a separate thread, or put this code in your paint handler. -
Not a word or construct used in the above post is not used in (free to air) tv commercials, played at any hour of the day in this country. To which are you referring? (I assume it is the aussie version of sod off)

Well you don't need me to spell it out, but I would also refer you to http://www.codeproject.com/Messages/3117206/HOW-TO-ANSWER-A-QUESTION.aspx[^].

I really can't be bothered with this rubbish. Am I to take it from you that the following are insults?
- Go away
- Nick off
- Sod off
- Bugger off
I'd agree that some may consider it insulting to be told to go away - I consider it insulting to be forced to vote in a democracy. But neither being told to go away or being required to vote is an insult. You may want to turn down the gain on your sensitivity stage.....

I am not in the least bothered by such expressions. I just agree with Chris that this sort of language is not appropriate in the general forums.

I won't bother pointing out the fact that you've changed your complaint when challenged. I will point out that
- I provided information that indicated the problem I had with the offending post
- There was no insult in my reply
- There was no sarcasm in my post
- There was no slap-down handed out
- Each of the words used are entirely 10 y/old sister safe
I've resigned myself to the realization that if you're prepared to agree, the best we can do is to agree to disagree. If that still doesn't suit you, I suggest you follow point 4 of "HOW TO ANSWER A QUESTION" with regards to my post that you deem so awful. Should there be sufficient repetitions of that direction, my post will evaporate. Before that point, I will not be taking a step backwards.

I've changed nothing; you are merely trying to justify your use of offensive language.
-
Indeed. On reflection, I did make a muck of that. I'd erroneously recalled that you first declared it an insult. Clearly, your definition of offensive and mine do not match. However, it is kid-sister safe. So, do we agree to disagree?:java:

Sure, although I'm drinking tea at the moment.

And just for the record, nothing in the foregoing exchange changes my opinion of your technical abilities (which is on the high side).
That's very kind of you to mention your favourable view. I have the same opinion of you. I eagerly anticipate the content of your responses whenever I see your username. (perhaps less so for the preceding conversation, though that's another matter :laugh: ) Gee computing is easy when people and personalities aren't involved! Upwards and onwards... Regards, Simon.
