   Realtime rendering vs non realtime
  Hi, I just watched 2 really cool opengl clips from gametutorials.com, 7th heaven and pctc. They were only 70k each zipped so i thought because of their size they wouldnt be any good, i was wrong  They were amazing,it got me thinking if you can do stuff like that with code and render in realtime and have a 70k file the same thing would take hour if not days to render in max or lightwave, although the quality would be better they would be like over 100 mb avi''s. So in the future when hardware is better will there be a need to render avi''s in max and stuff, sorry i dont know what that way of rendering is called, i''m guessing non realtimeAnother thing i noticed, the pctc exe was about 80k b4 i watched it and after i watched it the pctc file was nearly 4mb, how is that possible? it did say something about save textures b4 i played it so i guess it just saved them but i thought the textures would of have to have been there in the first place to be used, do their formats change when you complile the final exe? and that goes for sound to?Please excuse my noobishness 
  Resources, such as models and textures, can be compressed.The particular demos you mentioned decompress the resources they need prior to using them.zlib is most common lossless compression scheme, as far as i know.
