3D Model safety in Reader

-

if secure pdf, 3d models contained therein still vulnerable
ogle or 3d printscreen, yes? can software rendering forced prevent?

also, didn't see reference spotty support of acceleration on many platforms,
at least reader 7. powerpc mac minis have 16mb ati 9200 acceleration opengl 1.3,
and wasn't able old ati 7000 mobility system accelerate, despite
passing directx 9.0c 7/8/9 tumbling cube test. "pixel shader 1" in
knowledgebase article mean opengl 1.5 (or whatever equivalent
for directx) required? models i'm viewing small, typically ~100k (hundreds
or low thousands of polygons).

arduino bug sur secteur, batterie, mais pas en usb?

-
bonjour, je travaille sur un premier projet de barrière infrarouge pour photographier les oiseaux, https://www.youtube.com/watch?v=8xzqd9iefgy&feature=youtu.be quand je suis alimenter en usb tout va bien, mais lorsque je passe par une alimentation extérieur (9v 12v secteur 12v) plus rien ne marche, la led clignote, les relais basculent n'importe comment. il me semble que se sont les capteurs qui bugs...(pas assez de courant?) 2 capteur ir = 2x100ma 2 relais = 2x40ma 1 diode, 1 push buttom la carte elle même... on est environ à 400ma. je ne comprends pas pourquoi ça coince!   le régulateur de la carte est prévu pour alimenter la carte et quelques petits accessoires pas trop gourments en courant. si on lui en demande trop il chauffe et la tension délivrée s'effondre. l'usb est, elle, prévue pour délivrer jusqu'à 500 ma. avec tous les ma consommés il faut une alim 5v supplémentaire. alim 5v +/- 5%, avec le 0v relié à celui de la carte...
