glass type bending problem, refraction i think
if u look at this the plastic bottle just lets light stright through it, i tryed refraction but is their neway to make the background kinda bend in the plastic?
im tryin to get it like this but it wornt >,< Last edited by Sharp; 20-08-2003 at 07:54 PM. |

did you turn on 'ray trace refraction' in the render options menu?

Air doesn't has refraction. Fill it with water and give that fluid refraction. Just compare it with the real world, you have it right in front of your eyes .

true sod, air doesnt have refraction.. but the bottle isnt made of air and plastic have refraction.. not as much as glass though.
PS. seems like italy is winning that game I was hoping for germany.

actually.. air does have refraction too its only 1.00029 though.. vacuum has no refraction

Air does have refraction, air's refeaction index is 1.0003
http://art-design.smsu.edu/yarberry/...ion/index.html Bookmark this page its a good resourse.

For realistic glass Lightwave needs two surfaces to correctly calculate the bending of the light (Air, and Glass or plastic or whatever) as it passes through the object.
You can find a good tutroial here, just change the refraction index of the glass to 1.0003 and your set. http://www.geocities.com/CollegePark/9315/lw/tip4.htm

Hi, Im doing a print job based on a bottled drink here in the UK, I've had horrible times rendering and texturing. I started off with << FIRST OFF TEST RENDER >> but the customer did not like it so I changed it to look a bit like a smirnoff ice bottle. Its still real hard to render the refraction at a big size (print needs to be to scale at 300dpi or 300 pixels per inch) so, is there a way to render faster? I've tried turning off reflections and then pshoping them in last. Here is my latest. << LATEST >> its a bit more evil. The customer likes it but wants it more evil....
Any ideas give me a bell.

Lighting is the key for a evil looking drink bottle. Try sharpining the spikes and cast some lights from a low angle.

The spikes need to be blunted - Were die cutting around the image so the spikes would become an eye removing device. Most likely used widely over here in the national summer riots.
