8 bit _raw limitations.

Postby BuLL » 11-18-2006 08:26 PM

Just an opinion here ,so don`t slag me off;) This is just an opinion from an old git,who in LoA`s words"got a little smarter".lol.He knows what I mean,I`m sure.
I`m of the opinion that,this is probably the best looking terrain,as far as detail goes, with the present jo engine that you are going to see .

(And ffs I`m not bragging here,only an example...).
It`s simply because the current jo engine only handles a cpt generated from an "8 bit_raw file.
This is fine for images, but when we use this for heights we can.more often than not, see ugly steps in our terrain called quantization artifacts. This simply means that the jump from one height level to the next is large enough to be noticeable - we need more than 8bits of data to describe smooth height changes.
Hopefully their next generation engine,terngen ,will see an increase in "bit" technology/performance.(if that makes sense):)
That is of course ,if they stay with the terngen cpt generation method....
Anyway,I`ll shut my gob now......Cheers....ya gits
:D

Hahaha! I love a good bit of English banter!

Another superb job on the terrain in fact it looks like a landscape painting.

Is it possible to get the same detail and softness with a BHD terrain?

Excellent observation and description. I remember quantization, and your comments certainly make sense, but surely any more than 8 bits would compromise speed. So 8 bit may be the max in this ter'gen as you say.

I'll be interesting to see how 64 bit PCs (when instigated) fully utilise these aspects. There seems to be two avenues on the horizon. Dual processor, and 64 bit, architectures. It would be nice if they just skipped the crap and did both of them into the mainstream, so we could have some real nice games.

No doubt BullsEye™~cop~ your efforts are all part of this process, keep us the good work, and I watch your progress with interest.

3d geometry wise yep 8bit relief maps sux
but terrain textures can use true colour which can give alot more quality to the terrain ,but even more things to take into account the envirments also helps alot to

most people use "performance" setting in jo
which can make the even best detailed terrain look like crap

i recommend any elite player to switch to normal settings with antialias and full frame effects your notice game becomes alot better looking and harder to see/spot enemy

I can't see you getting much co-operation on that score (as much as I agree) because it just means you'll be the one getting killed all the time, long before you see anybody.
I can remember getting my new graphics card, and winding the settings up. Lovely looking maps etc (as you said) but the added detail meant I couldn't spot people, as easily as they could spot me. The lack of detail at long distances, makes it easier to spot people.

I soon got fed up getting mull'd, so back down went the settings.

Mind you I suppose thats just because I'm not an 'elite' player :p although I must make a note to turn the settings up for screenies. :cool:

This is why being a sniper in delta force two is useless most of the time. You could run 800m out and still be quite obvious as a little black pixel on a brown hill. Lower graphics, people stick out more.
