Digg  swf_lookat
Define a viewing transformation
(PHP 4)
Code Examples / Notes » swf_lookathotkey
You can really do stunning 3D effects using swf_lookat() [and swf_ortho, of course]. Here is a little example of doing a simple 3D-rotation around a text. The Text is split up into 2 parts, because Flash does not (yet?) support perspective-skewing, only rotation, 2D-skew and scaling. But if you split your 3D-object up into several parts, each part is transformed seperately and you can trick around that loss of perspective-skew. Have a lot of fun experimenting with that piece of code! regards HotKey ^ http://www.SPR.AT - - - - - - >8 - cut here - - - - - <?php Header("Content-type: application/x-shockwave-flash"); swf_openfile("php://stdout", 320, 200, 25, 1, 1, 1); swf_ortho (-100, 100, -100, 100, -100, 100); #create 3D coordinates swf_definefont (0, "Pix3"); swf_addcolor (0, 0, 0, 1); swf_fontsize (10); swf_fonttracking(0.2); for ($i=0; $i<628; $i+=8) { $j = $i / 100; swf_pushmatrix (); swf_translate(0,0,0); swf_perspective(100,1,0,10); swf_lookat(sin($j)*60,50,cos($j)*60, 0,00,0, 0); swf_definetext (1, "HotKey@", 0); swf_translate(-50,0,0); swf_placeobject(1,10); swf_definetext (2, "hehe.com", 0); swf_translate (55,0,0); swf_placeobject(2,11); swf_showframe(); swf_removeobject (10); swf_removeobject (11); swf_popmatrix(); } swf_closefile (); ?> - - - - - - - - 8< - - - - - - - - *EOF* |
