Image_3D: Bug 17008 [Open] Bad layers detection

Image_3D Bug
Reported by waterwall
2010-01-18T07:24:02+00:00
PHP: 5.2.4 OS: Ubuntu Package Version: 0.4.1
Description:
------------
Image_3d renders it in wrong way. I guess the problem is to check which object is in front (or back).
Test script:
---------------
$world = new Image_3D ();
$world -> setColor (new Image_3D_Color (240, 240, 240));
$light1 = $world->createLight('Light', array(0, 0, 300));
$light1->setColor(new Image_3D_Color(255, 255, 255));
$cube = $world -> createObject ('cube', array (210, 70, 30));
$cube -> setColor(new Image_3D_Color (0, 0, 255, 0));
for ($x = 0; $x < 6; $x++){
for ($z = 0; $z < 2; $z++){
$cube = $world -> createObject ('cube', array (210 / 6 - 2, 70 / 17 - 2, 30 / 2 - 2));
$cube -> setColor (new Image_3D_Color (255, 0, 0));
$cube -> transform ($world -> createMatrix ('Move', array (($x + 0.5) * 210 / 6 - 210 / 2, -35 - 70 / 17, $z * 30 / 2 - 30 / 4)));
}
}
$world -> transform ($world->createMatrix ('Rotation', array (45, 0, 0)));
$world -> transform ($world->createMatrix ('Scale', array (3, 3, 3)));
$world -> setOption (Image_3D::IMAGE_3D_OPTION_BF_CULLING, false);
$world -> setOption (Image_3D::IMAGE_3D_OPTION_FILLED, false);
$world -> createRenderer('perspectively');
$world -> createDriver ('SVG');
$world -> render (1024, 768, 'phptemp/budynek.svg');
Expected result:
----------------
I try to create 3d image. There should be the big blue cube and some small, red cubes on that big one.
Actual result:
--------------
