lens effect !!!help!!!

[igova]

hello
There is no ability to realize the lens effect for the glass material.
The refraction effect on edges of object (material) must be different...
Thanks

[stefan]

if you modell the lense correct it makes the effect of course, juts modell alense and use refraction.

cheers
stefan

[igova]

The object can be any/
The material is necessary for this problem

[stefan]

the refraction is dependen of the material shape like in real physics.
t
with a flat object you get not the effect of a lense p.e. it must be curved, like in real world. or do i missundertsand you?

cheers
stefan

[stefan]

or do you mean fresenl effect instaed of lens effect?

that is in and controlled via the IOR.( for realworls glass you must also use reflection and its ior of course)
again like realworld.

cheers
stefan
