Hi

Hope I am posting in the correct thread -

I am trying to include an image that will displayed constantly in the same location for the entire period of use of the applet. On setup the title displays, once the applet enters the draw routine, I can no longer see the title. Because of the background() (which I need). Further more, when I disable the background(), my title has been traslated and scaled to another area of the display and is affected by the what is done in drawTitleImg.drawC();

thanks in advance for any assistance

Hi JohnG

I quickly re-coded up the processing project, the panels and graphic are being displayed semi-correctly although they are still being effected from the translation which occurs in the next instructions. I have changed it around and am still getting a translation occurung where it should not happen.

thanks for you input (one issue down and one to go)...I am stumped here, I would assume that what I am attempting is quite simple? oh, I am using 0119

thanks
angelo

thanks for your help on this - I must be doing something really wrong here. I dd what you suggested and it does the same thing....

I removed the following lines from DrawHeader
   float cameraY = height/2.0;
 float fov = PI/2;
 float cameraZ = cameraY / tan(fov / 2.0);
 float aspect = float(width)/float(height);
 perspective(fov, aspect, cameraZ/10.0, cameraZ*10.0);

and placed them in the draw(){} following the background();

still no cookie...I will trying starting from scratch, maybe there is a problem specifically here on my side.

thanks JohnG - Out of desparation, I just tried that very suggestion.  Just came back to thank you for your help...

So. Thank you-
