[Development] WoW Model Lib

[Cromon]

Hello everybody!

At the moment im creating a .NET Interface for everyone of you capable using C#, VB.NET, J# or CLI/C++. It will give you very simple classes und functions to render wow models, change the models (e.g. the vertices) and save the models. Also it will contain a directX renderer that creates very simple context to render into form-controls. The other part is an interface to deal with MPQ-files without big overhead!

Here are some examples:
1. Loading a listfile of a MPQ:

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        WoWRender.MpqHandler m_handler;

        private void button1_Click(object sender, EventArgs e)
        {
            if(m_handler == null)
                m_handler = new WoWRender.MpqHandler();
            listBox1.Items.Clear();
            openFileDialog1.ShowDialog();
            string fName = openFileDialog1.FileName;
            if (fName == "")
                return;
            m_handler.AddArchive(fName, false);
            string[] files = m_handler.GetFileList(fName);
            if (files == null)
                return;
            foreach (string s in files)
            {
                listBox1.Items.Add(s);
            }
        }
    }

2. Modifying a .M2-file:

            MpqHandler handler = new MpqHandler();
            handler.AddArchive("data\\expansion.MPQ", true);
            handler.AddArchive("data\\common.MPQ", true);
            handler.AddArchive("data\\common-2.MPQ", true);
            handler.AddArchive("data\\patch.MPQ", true);
            handler.AddArchive("data\\patch-2.MPQ", true);
            handler.AddArchive("data\\lichking.MPQ", true);

            ModelCreator creator = new ModelCreator(handler, null);
            model = creator.CreateModel(@"World\Expansion02\Doodads\DragonBlight\DragonBlight_Tree01.m2");
            foreach (Vertex v in model.Vertices)
            {
                v.X *= 2.0f;
                v.Y *= 2.0f;
                v.Z *= 2.0f;
            }
            model.Save("C:\\Programme\\Tree.m2");

3. Render and animate a .M2 model:

namespace RenderTest
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        WoWRender.WoWRenderMgr mgr;
        M2Model model;

        private void Form1_Load(object sender, EventArgs e)
        {
            mgr = new WoWRender.WoWRenderMgr(panel1);
            mgr.OnRender += new WoWRender.WoWRenderHandler(OnRender);

            MpqHandler handler = new MpqHandler();
            handler.AddArchive("data\\expansion.MPQ", true);
            handler.AddArchive("data\\common.MPQ", true);
            handler.AddArchive("data\\common-2.MPQ", true);
            handler.AddArchive("data\\patch.MPQ", true);
            handler.AddArchive("data\\patch-2.MPQ", true);
            handler.AddArchive("data\\lichking.MPQ", true);

            ModelCreator creator = new ModelCreator(handler, mgr);
            model = creator.CreateModel(@"World\Expansion02\Doodads\DragonBlight\DragonBlight_Tree01.m2");
            model.Effects.ScaleX *= 0.2f;
            model.Effects.ScaleY *= 0.2f;
            model.Effects.ScaleZ *= 0.2f;
            model.RenderContext = mgr;

            mgr.BeginRender();
        }

        private void OnRender()
        {
            if (model != null)
            {
                model.Effects.ScaleX *= 1.01f;
                model.Effects.ScaleY *= 1.01f;
                model.Effects.ScaleZ *= 1.01f;
                model.Render();
            }
        }

        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
           mgr.EndRender();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            mgr.BackgroundColor = Color.Blue;
        }
    }
}

Before the first release i need to implement some more threadsecurity and some more exceptions need to be thrown.

I hope that there will be more people acting in Modelediting if they get a easy library to modify and display the models!

Of course it will contain also support for ADT files so you will be able to change vertices for maps (no limit for exploitation, as it will allow every ADT in the game to be changed).

Hey, this is awesome, keep it up! 4x +Rep from me

[piller]

looks interesting. cant rep to this thread

[Mitron]

Awsome i maybe start with model editing more serious when this release =3 cant rep tho :/

[Bjarke]

Hmm, you got this working with m2 viewdistance and collision? (For world objects? ) would be awsome (the tools we have now are not working proberly, and to make 1 object with collision and viewdistance we need 4-5 diffrent tools :S)

but +rep for the great work so far

[Cromon]

Collision and viewdistance actually allready work in yiasedit if you spawn an MDX into a tile and it only intersects the spawntile. As im atm calculating the bbox of the models itll be easy to calc the appropriate MCRF for the models.

[schlumpf]

Cromon: We are not talking about the MCRF here.
Once again: Why did you make another lib if there already is one? ._. Yay.

[Cromon]

MCRF -> collision, no MCRF -> no collision. If you mean another collision just tell

Well, why do we make another computergame? There is already one. Why do we make another car? There is already one. Why do we make a new computer, there is already one? Why do we make new mobile phones, there is already one?

[schlumpf]

._. M2.Header.floats

[Cromon]

Ah, kk, thanks, will include that.

[Cromon]

Its not very difficult to make that collision and viewingstuff. If you save the file it automatically checks every boundingbox in the model if there is something to change. So the viewingdistance thing is working correctly, just need to implement a tweek on the collision as colliding with the scaled object atm results in a crit :P

[[Blinded]]

Thanks for posting this, it gave me a little view of rendering.
Tanks alot.

[Cromon]

Ok, made some more things:
1. You can change the boundingvertices on your own. Display a bounding shape out of the triangles as wireframe to see if it fits the modified model. scalar scaling on every vertex is pretty simple. Just scale all vertices and all boundingvertices with the same factor and you have fully working collision on the sized model ingame.

2. Particleemitters:
You can change these emitters. change the rotation of the particles, change the outputlocation of the particles, change the size of the particles, ...

When ive done the M2Models i will release the first betaversion and head up to WMOmodels.

[Demonshade]

sweet!! will this be integrated in yiasedit?

[Cromon]

Of course

Adding some handling for the animationblocks to change animations.
