The problem is when i want to convert coordinates like (x,y,z) to 3d environment. IS there any relational tool or something like that that take as values 3 dimensions and turns into a 3d shape (cube something) ?????????? Thanx anyway....

Cannot modify header information - headers already sent by This is the message when i enter the below easy and small source code FOR CREATING A FILLED RECTANGLE : <?php header("Content-Type: image/gif"); $im = ImageCreate(100, 100); // colors... $black = ImageColorAllocate($im, 0, 0, 0); $white = ImageColorAllocate($im, 255, 255, 255); // draw rectangle ImageFilledRectangle($im, 25, 25, 75, 75, $white); // Print and destroy the image ImageGIF($im); ImageDestroy($im); ?> After that message i get a lot of unrecognizable string characters ... What is wrong ????? Anyone?

Does anyone know how can i use some values (x,y,z) so to draw a cube ? I have the values written in a plain text . Are there any useful tools for this ? I want to draw 3dimensional object having these values (including laso height of x , height of y , height of z) . Any help appreciated...
