Using minecraft screen render

Hello.
Is it possible to use the screen render from minecraft? I mean if I give to some class coords and block types, it would create for me screen (image). The screen render is the program which creates the game - what I see when I play Minecraft. Is this somehow possible?
Thanks.

 

Simple answer, no.

EDIT: maybe spout can do this, not sure.

 

Ok so only way will be to create own screen render... it's propably only way ... thanks for reply.

P.S.: What class in Minecraft jar file creates the screen with players, animals, blocks ... what I see when playing MC?

 

It's not that easy and not just a simple class. Well window rendering is probably in the main minecraft.jar class (called Client.java but I was modding ages ago). Maybe just tell us what you want to achieve? Maybe there is other method ;>
