try to render with cycles and it takes long time.. anyway i found out that it will resume after i close my laptop to put in sleep and open up to use again.

But is there a way to use it to model something, while blender is rendering?

Never tried to model while rendering but you can have more than one blender instance running at the same time.

possible to explain more? does it mean i can 'pull' out another view to model same time? I just want to do sth else in blender while rendering.

I also notice if i press f3 during rendering..i can save as jpg too? so there is option i can save half way? and it will continue rendering?

Unless you have a pretty chunky machine it would be tough - rendering can take a lot of RAM / CPU and modelling is not exactly light either 

i render something with uneven surface..maybe that's why it takes few hours.. so while rendering, i can't play around blender at all..

so are you guys render at other machine? just learn about 3d, didn't know render takes a lot of time.

I don't know if you can model and render at the same time in the same blender instance, sounds dangerous to me. I remember I once did something like this and the result was a corrupt render because changes were applied to final render while I was editing. That's the reason I told you could launch more than one blender instance, meaning you can open blender twice and render in one and do something else in the other.
As has been said you need a powerful machine to do this or multiple computers. If using a single computer you have to share resources between tasks (CPU, GPU, Memory, HD I/O). Cycles uses a lot of CPU or GPU to render, if you use GPU you can use CPU for modeling on another window if you use CPU you have to limit the number of threads used by cycles. And be sure to have a lot of memory.

I usually leave the computer rendering at night all alone or use one of my other smaller computers while rendering. Render is very fast in today's computers, I remember when I started using computers simple renders could take two or three days to complete.

oic..so i can open 2 blenders..i didn't understand what u said at first. thanks!

anyway, i just put the render going on..and it continuous render when i just sleep my laptop and open again.. i seldom shut down laptop.
