Not dead...

Correct Lighting! Huzzah!

Posted by , 23 January 2005 - - - - - - · 146 views

About a month ago I got distracted by something and decided that working out how to display Doom3 MD5Mesh models, complete with diffuse, normal and specular maps.

After a few issues with my maths being a tad tits up (and mucho thnaks again to joanusdmentia for helpping me sort out my stupidness) I finally got model loading and displaying with a diffuse map up and going towards the end of last month.

Since then I fiddled with the normal mapping, and I thought for a while I had it right but it always bugged me that something wasnt quite right and finally today I worked it out, stupid light position wasnt in the same space as the EyeDir, so the LightDirection vector wasnt remotely sane, so while lighting mostly worked it was a tad flakey.

Before I worked that out I added the specular parts to it as well, closely matching the Doom3 system (it currently lack light fall off values, chances are I'll use maths to work that out however).

Next on my list, animations, first in software then in a vertex shader (however, this could depend on ATI fixing their GLSL compiler as atm it has issues when you try to make a skinning shader).

So images for you...

Model ad texutres from Doom3 ofcourse.
The white thing is the light position.
the blue, green and red lines are the normal, tangent and bi-tangent at each vertex.

Pet hates....

I'm an angry person.
Most of the time I'm pretty close to the edge of just abusing people, hell most of the time in real life I cross that line and lay into people to expose their own moronic habits.
It amuses me.
I'm probably going to hell.

However, in forums I can often refrain, normally just using cutting sarcasm to get my point across, but my tolerance level for arsehats has just run out.

So, today I bring you the first in what might or might become a series of me ranting about morons, either on here or in the real world, and frankly given my view that 99% of the world are infact morons who shouldnt be allowed to reproduce material shouldnt be short.

First up; People who cant write a remotely descriptive forum message title.
Seriously, wtf is up with that? OK, you want to learn to program, ok you are new so wont know everything but is it too much to ask for that you put some thought into your title!
I've infact taken to looking at them, coming up with an answer and just not posting it, I get some sort of glow knowing that I have the answer but I dont feel the need to help a moron who cant even think of a title beyond 'help', 'it doesnt work' or 'why'..

Secondly; People who post the same answer as you.
Now, ok, forums arent real time and sometimes you'll get a couple of post appear in a few mins coz people are writing a large post but every so often you get some one who, for god knows what reason, decideds to post an answer and then GIVE LESS INFOMATION than the post before them.
I'm not talking by minutes either, the last time this happened to me it was 2 fricken hours!!! between my post and the person who posted basically the same thing but with LESS infomation than I had given!
Seriously, wtf were they thinking? How is that remotely logical?? Did they think that they would be loved for repeating and duplicating the infomation but leaving out huge chunks?? seriously, I cant understand it.
Heck, I've posted the same thing by a few seconds before now and deleted it because the other post contained more info, but that was by 2 fricken hours!!
I dispair at times.

And finally, another amazing thing happened.
Someone asks a question, I answer it, at which point 4 or 5 people start debating how todo it, apprently ignoring my answer and a page later arrive at the same conclusion I got to in the first reply.
That the kinda thing which firstly makes me think "hell yeah, I'm great, I can out think these people by 2 pages" and I feel good until I realise that i've apprently out thought morons by 2pages and its not such a great thing.

Ah well, time for dinner and then another night of being sarcastic at people and mocking their lack of logical thought processes... mine is a hard life...

Time for a break?

Ah, ratings.
Love 'em or hate 'em it seems you cant escape them.

Before I continue I'm fully aware that what I'm about to put here could well make what I'm about to talk about worse, infact I'd think it more than likely but never mind [smile]

I like to help people, those of you hang around the OpenGL forum will probably have noticed my prolific posting in that forum, helpping out where I can and even giving alternative infomation. Heck I dont even mind that the posts I make both there and in other forums often seem to go all but ignored.

However, all that said, its nice to know you are appricated, with either a thanks or, these days, a little rating boost. It makes me feel good inside when I log in and happen to notice that I've gained a few points, be it 1, 2 or more and it helps me want to help even on the days I feel a bit off.

Now, I dont know what my rating is as you read this, and chances are if a few people read it will indeed take a pluge, but on the 12-Jan-05 I happened to notice it had made it to the dizzy hights of 1424 and I was pretty chuffed. I'm pretty sure its not down to me being popular, its not like I'm one of the loungue 'inner circle' and I dont talk to others off here, I just come on, answer questions and thats pretty much it.

So, imagine my shock when, today, I logged on to find that I'd dropped back to 1411 and then just before this post 1407. I even stopped and did a double take. Now, I've lost points before now, 5 or so a few months back, and I never worked out what it was for but in this case its down to the old 'popularity contest' issue it seems.

You see, I quickly reviewed what threads I'd taken part in, post drop;

- a couple of opengl ones where I was as bit terse with my answer, but it was technically correct
- a thread about WMD in Iraq
- a thread about global warming (where I was infact refered to as 'people like you' by one of the posters because I couldnt see what they was on about)
and post the small drop I did a longish post on how a GPU access data and how the two different formats (CPU friendly and GPU friendly) effect this.

So, lets take a close look at it.
The technical thread,posted after my main drop, that was correct and last I'd checked no one has posted to disagree with that I said.
The OpenGL threads, well as I said, I was a little short but in one case next to no info was given and the other was a simple search, so I wouldnt have expected owt.

So what does that leave us?
Oh, surpise surpise, the politics and science threads, where it seems because I disagreed with someone view point (despite being polite about it and stating my reasons clearly and never attacking the person in quesiton) I've lost the 'popularity contest' and been rated down.

The thing is, because my rating is so high it was either;
a) alot of low ratinged people
b) a couple of higher rated people
c) a mod or staff
I know this because I could only effect a person with 1000 by 12 points when I rated them the other day on the 2nd to highest level and as your rating power changes depending on relative ratings.

So, whats the upshot of this, well its that I'm now wondering is it really worth me posting my arse off to help people when it seems that if you disagree with the popular people, even politely, any apprication you've amassed gets wiped away...

So, right now I'm pretty demoralised and considering a few days/weeks away from the posting side at least.. although, I admit this couldnt have come at a better time, I've got work todo and possibly the beginings of a relationship of sorts, so maybe it will all work out...

either way, as I'm not popular enuff this will be my only comment on it, no large goodbye thread in the lounge or owt like that, just this entry so that if I do it and someone does wonder 'what happened to _the_phantom_?' at least there is a reason and those who rated me down for no more than clearly and politely expressing my views can feel happy at having driven away one of the more helpfull members of this community, as voted for by those I helpped.

Lazyness... terminally?

Posted by , 26 August 2004 - - - - - - · 263 views

Its pretty much a well known fact among those which know me that I'm so lazy I cant even be bothered being lazy. Its got to the point where people fall of chairs shocked when I do some coding, myself included. OK, this hasnt prevented me from getting a rep as a god like coder (though I'm sure some people on here could put me to shame) its something which has started to bother me slightly.

Go back about 8 years, to when I was 16 and all I had was an Atari STe. Back then I'd think nuffin of spending 12 hours a day during the holidays knocking out code and fiddling with things. Heck, I still view my greatest achievement to date as intergrating a 50Khz MOD reply routine into STOS as an extension via alot of assembly hacking, infact nuffin so far in my life has topped the feeling I got the day I first got it to work, I'm sure you could hear the shout of 'yes!!!' across the street, hehe.

Ever since then, its felt like everything has been going down hill, which is really hurting my 'get up and go'. I still enjoy it when I get into a coding vibe but thats happening less and less.

What I'd REALLY like to do is a game of some sort (ofcourse with my own engine [grin]) yet, while I have ideas in my head I cant seem to get them all to line up and make sense... maybe I should start writing them down.

So, meh really, I know I've got stuff I want todo but I just cant get myself going, heck I've got books on C++ I want to read, yet it seems as soon as I open the book I start yawning, never a good sign...

Hmmmm maybe I need a change of scene, go and sit in a cave in Wales or something for a while, see if that helps....

that is all.

I supported GD, what did you do with your time?

Yep, the GDNet+ has landed!
and i've got a warm glow inside from parting with cash to help keep the site alive and kicking.
plus bragging rights of being the 2nd person to sign up [grin]

That is all!
