Hi All,

I get good progress on the engine.
I've added several features.
Of course they are not final and may change with the evolution of the engine but they still work :)

I have added :
- Multi camera support ( Up to 8 cameras )
- OpenGL lights (need to fix light 0 issue)
- Objects instancies (share mesh and texture)
- Load/save 3D objects.
- Compatibility with object/camera position/rotation & command set.

Here is a small shot of the actual demo :
Resized Image

EDIT:
Voici le code source de cette d?mo :


float XAngle = 0.0;



void DarkLoop( void ){

  DESetDisplayMode( 640, 480, 32 );

  DECls();



  DELoadImage( "Images/x4.png", 1 );

  DEMakeObjectBox( 1, 5.0, 5.0, 5.0 );

  DELoadObject( "cube.deo", 1 );

@freddix

Congratulations with your progress.

My one suggestion would be to make functions such as DERotateObject() cumulative. Right now, it looks like you're resetting the orientation each time and then rotating it by a new angle (unless you've got the box rotation speeds increasing every frame). When you write a game or world simulation, you generally want to move (including rotation) objects from where they are to a new position based on their speed. This is much easier to do if you can just call DERotateObject(4, deltaTheta, deltaSigma, deltaPhi), or something similar, where "delta" means the change in angle, rather than the new angle. You could always have a DEResetPosition() method if someone wishes to track the angles externally to the object.

Just popping in

@Freddix
Happy to see that your project is progressing well, congratulations!

@Hans
Maybe Freddix can add a flag at the end of the command to set the relative or absolute movement, something like:

DERotateObject(4, x, y, z [, relative])

<relative> could be true by default

@Allanon & Hans:
Hi and thank for your comments.

In fact, I will only use direction rotation values.
But there will be these commands:


ROTATE OBJECT : ROTATE OBJECT Object Number, XAngle, YAngle, ZAngle

MOVE OBJECT : MOVE OBJECT Object Number, Speed

POINT OBJECT : POINT OBJECT Object Number, X, Y, Z

MOVE OBJECT DOWN : MOVE OBJECT DOWN Object Number, Value

MOVE OBJECT LEFT : MOVE OBJECT LEFT Object Number, Value

MOVE OBJECT RIGHT : MOVE OBJECT RIGHT Object Number, Value

MOVE OBJECT UP : MOVE OBJECT UP Object Number, Value

XROTATE OBJECT : XROTATE OBJECT Object Number, XAngle

YROTATE OBJECT : YROTATE OBJECT Object Number, YAngle

ZROTATE OBJECT : ZROTATE OBJECT Object Number, ZAngle

TURN OBJECT LEFT : TURN OBJECT LEFT Object Number, Value

TURN OBJECT RIGHT : TURN OBJECT RIGHT Object Number, Value

PITCH OBJECT UP : PITCH OBJECT UP Object Number, Value

PITCH OBJECT DOWN : PITCH OBJECT DOWN Object Number, Value

ROLL OBJECT LEFT : ROLL OBJECT LEFT Object Number, Value

ROLL OBJECT RIGHT : ROLL OBJECT RIGHT Object Number, Value

so it will be possible to rotate direction object with angle or by altering the actual angle.

Fred

@All

Hi All,

I've made a custom convertion tool on PC with DarkBASIC Professional
and I've converted my 1 st 3D Object from PC to Amiga.

I had done some sort of "import" functions.
Of course, once the object is loaded in the engine, it can be saved with :
DESaveObject( char * FileName, int ObjectID );
So the object is exported to the AmiDARK Engine 3D Object format :)

Here is the snapshot link :
http://www.odyssey-creators.com/AmiDE_Imported3D_1.jpg

I've put it as a link because it is large [ 1280x1024 pixels ]

Regards,
Fred

Very nice.

Keep up with the good work.

It is possible to implement filters? Bilinear filtering, antialiasing and os on...?

thank you

@freddix
Sorry, at moment i know nothink about that Engine, can you explain a bit more about that project ? It's 3d engine which will allow other coders make their 3d prods by easy way ? (like some kind of Demo-machine ?) Or it's somethink different ? And maybe any beta-alpha binary are possible to test ?:)

@AmigaBlitter :
Yes it is planed.

@kas1e:
AmiDARK Engine is similar to DarkGDK from thegamecreators : http://gdk.thegamecreators.com/
It is a SDK to help develop video game easily using OpenGL/AHI,etc ... It should cover many commands set like the ones available in DarkGDK. I should advice you to get alook at the link given upper. It should give you an overview of what kind of Product AmiDARK Engine will be.

Concerning Alpha/Beta binaries to test, it is also planed. I will release soonly a small 3D demo showing the various AmiDARK Engine commands actually working.

Concerning Beta testing it is also planed but it will only start when the project will be more advanced. Beta tester will have to sign an NDA (Non Disclosure Agreement) if they want to be ~.

I hope I've answered every one.

I'll keep you informed

There are much more commands to be coded and that are not yet available (AmiDARK Engine is in Alpha state currectly).

I hope these informations give more on the overview of the project.

All we have to decide is what to do with the time that is given to us.

Yeah, thanks for good answer. That all what i need to know :) Indeed, that project looks very good, and i read that topic becouse just saw the first "nice" image and when i see these "easy commands", which remind me some kind of demo-machines.

If you will be in interest about any beta-tests / finding bugs, etc, so just let me know , i with my peg2 will help you with all that NDA and so on :)

List of fucntions looks pretty clear and understanable ! That cool. Imho that engine can be also used not only for games, but also for making scene-demos (like Karate by m4nkind for 68k/ppc amigas) ?

Have you plans to add support of some "music" formats ? Like mp3, ogg, tracker modules maybe (like mod, s3m, xm, etc) ?

Technically you can create demo with AmiDARK Engine.
Actually, it is only compatible with Amiga OS 4.1 (not classic)

Support for various music file format is planed. I don't know exactly which formats will be supported but theorically file format like : MP3, MOD, WAV should be supported.

I will not add all support but if sources are available to add it, I will check and maybe it'll be added in final AmiDARK Engine :)

Just popping in

@freddix

Looks like SDL_Mixer is a winner (mp3, ogg, mod and wav) and is easy to use too.

Quite a regular

Some news on the project.
I've added some new commands to the SDK :
- Object scaling
- Object ghost
- Object alphamapping (using blending in fact :p)

Fog handler

Here is a small shot with a ghosted object and fog enabled :

EDIT:
I've also added commands for drawind priorities :
DEDrawAtFront : Trace 3D then 2D
DEDrawAtBack : Trace 2D then 3D.
I had to put 2D drawing in an extensible list for display.
