// Title: Forsaken v0.926 Hi-Quality PC-Demo
// Author: Zigrath / Heed
// Mail: zigrath@online.no
//
// Desc: My first demo ever, to be contributed at The Gathering 2003.
//		 Kaktusen provides music, gfx and ideas.
//
// Linked libraries: 
//	* d3dx8.lib d3dxof.lib d3d8.lib dxguid.lib winmm.lib fmodvc.lib comctl32.lib 
//
// Bugs: 
//	* Heap block modified past requested size of 46020. Scene04/05? Might still exist.
//	* Set3DPlaneVBRect() is NOT foolproof with the different vertex formats. Only one flag after XYZ and NORMAL can work 100%.
//       
//
// Compatibility checklist:
//	* timebased random generating (i.e. feed the chicken vibration)
//	* memory allocations (textures above 1024x1024?)
//	* test product on a slow computer and a really fast one
//
// Todos:
//	* ShowBlurTexture() or alternative blurring
//	* sort bloodparticles in scene05
//  * metaballs:  bruk en sum av vektorenE fra ballenes sentrum ganger verdien fra metafunksjonene dems
//	* Fog on water in scene01?
//	* Scene04. Metaball and marching cubes. Improve melting.
//	* DX SDK has some nice textures. Might find a replacement for flies.
//	* Point sprites?
//	* World-transformation correction for fireflies, we want sprites to look 2D
//
// Effect ideas:
//	* Scroll-in transparency and blur effect on introtext
//	* Animated inverse-color rectangle from 4 cross-screen lines
//	* Rotate the three manga-heads transparently on top of eachother
//
//
//
// Memos to self:
// 28.11.02: Spank me. The intro is finally getting somewhere..
// 06.12.02: Bugs aren't all that bad, it is fixing them that really sucks.
// 20.02.03: Intro is nearly done, and I'm sort of pleased with it - but not overjoyous, mark you.
// 20.02.03: So much to do, so little time. So hungry.
// 09.03.03: Intro has been improved a lot, the flies in particular. I'm currently working on the
//				tunnel effect, and I'm quite pleased with it. I even got most of the plasma effect
//				in place already.
// 10.03.03: Skipping sleep is good for demos, but that's just about it. 
//			 I and kaktus have produced a number of concrete ideas that's going to be part of the demo.

// 11.03.03: The soundtrack is finished, thanks to a great job by Kaktus, and it is awesome!
//			 He has also set up a pretty concrete plan for where and how to apply the different
//			 scenes and effects we have discussed. This plan is based on the music, and should
//			 give a very thorough experience if we succeed to follow it.
//			 Splashscreen 1 is nearly done, and I found a better looking way of creating the
//			 plasma effect for the tunnel. This demo is gonna be great! :D

// 28.03.03: Lots have been done. The water effect in the intro has been improved a heck of a lot,
//			 and it's now looking sweet!
//			 I have also finished most of the textscene in musicpause1, and next up will be the
//			 metaball. I'm really excited about that one.
//			 The rest of the scenes are more or less finished on plan level, and they should
//			 be far faster to create than the scenes so far.
//			 The deadline is two and a half week from now, and we have finished about 2 minutes out of 5.
//			 But I think we'll have enough time to come up with a pretty decent demo.

// 30.03.03: I finished off the blue tunnel scene. It's not perfect, but it'll do. We're short on time already,
//			 and I have that pesky metaball to figure out shortly. The big scenes that remain are.. still many.

// 12.03.03: Time is running out and I'm so busy I can't even take a piss. And when I occasionally do,
//			 it smells like honney corn.
//			 A lot has happened since last post however. I have come far with the metaballs (they are still too slow and
//			 don't look too good because of resolution on grid). The mean tunnel at scene5 is nearly done. The particles
//			 are basically finished, it's just some camera stuff to set up and flash-effects. Shouldn't take long.
//			 The nature splashscroller and credits are also basically in place, just missing some textures and finish.
//
//			 Finally, I have made a temporary 3d-object for use in scene8 and threw in some rotation. I'm thinking of
//			 adding more objects and some particles, and that should pretty much do it.
//			 I do have accomplished a lot the past 12 days, and I'm finally seeing an end to this demo. About 30 seconds
//			 remain that I haven't put any work to yet, and they should only take a day or two to implement.
//			 Who knows, we might actually finish this demo in time!

// 14.03.03: Two days to dust off. These holidays have been very useful, and I have been able
//			 to put down quite a share of work. The major accomplishment is a pretty much done
//			 scene8 and I am thinking of using much of it in scene9 as well. And that narrows
//			 it down to a 15 second lastscene that I intend to put a lot of work into, as to
//			 give a good last impression of the demo.
//			 The camera movement in scene2 and 5 has been improved a lot, scene5 in particular.
//			 The particles in scene5 are also moving a bit random now to look more alive,
//			 and it works pretty decent. I'm still thinking of experimenting with the textures a
//			 bit though, but there's plenty of time for such at the party.
//			 I also added introtext for the poem in the soundtrack. The textures are rather
//			 temporary but most of the work there is done. And I'm thinking of adding some blur and
//			 "scroll-in transparency" effects on the textlines.

// 19.03.03: It is Saturday morning, and less than 4 hours to deadline. I think we have managed to scrap together
//			 a rather decent demo, at least for a first attempt. We had to cut the soundtrack about 20 seconds at 
//			 the end, since we couldn't get enough time to fill it all. Kaktus did a good job, and the soundtrack
//			 now fits the demo pretty well (and vice versa).
//			 We have put a lot of work in refining the textures and adding quite a deal of fill-effects.
//			 Of course I wish I'd have more time, but then again I'll be happy to wrap up this product.
//			 I've spent an enormous time and effort making it.. and as long as it shows up ok on the bigscreen
//			 I will be quite satisfied with this demo.
//			 My fingers are crossed.
//			 There is a major bug in the demo however. It seems ATI cards mess up the fade-sequences, so it is
//			 currently not playable on those. I'll try and fix it before deadline.
//			 Except for that, all scenes are in place more or less. The metaballs look like crap, but I just don't
//			 have time to fix it.
//			 I'm quite excited how this compo will turn out.
//			 
// 
// Disclaimer: Be aware of the bugs, they bite.
