Re: 3D drawing back textuers come through front textures

ok i fixed it :D

changed
projectionMatrix = Matrix.CreatePerspectiveFieldOfView(MathHelper.PiOver4,
                                                                    aspectRatio,
                                                                    0.0001f, 1000);

to

projectionMatrix = Matrix.CreatePerspectiveFieldOfView(MathHelper.PiOver4,
                                                                    aspectRatio,
                                                                    1, 1000);

i guess nearplaneDistance was to small
thnx everyone for help

but i can tell one thing that its not the model
the model itself works fine in original game from a friend of mine.

Yeah i tried it with alphablend off but thats not helping and i also need it because the shadow shapes have transparent textures.
Ok i tried creating a cube model, but im really noob @ blender. i tried a tutorial with blender and xna but that gives me a huge cube and the textures of that cube are even more messed up

Yes it certainly does look like z-fighting.

Maybe the model has two cubes in it of the same size or has corrupted indices.

I would also turn off AlphaBlendEnable and AlphaTestEnable just to be sure its not doing anything weird.

BlackWolve — Thu, 09 Jul 2009 08:33:52 GMT

it already happens with 1 model i just found out.
Could it be the model it self?
i'll try to make my own model and see if it works.

well i searched and checked but im not drawing anything twice.
I will try now to draw 1 block and then 2 etc.

Do those strange grey bits flicker around if you move the camera or objects? If so, I'm even more sure it's Z-fighting. It looks like your textured cubes are fighting with some non-textured cubes. Maybe your Draw() is actually being called multiple times with the same Vector2 position in a single frame? Try drawing only a single brick and debug step though to confirm this isn't the case.

no its still the same
as http://filedump.sargeman.nl/gooddrawing.JPG
will post some more info tonight. im @ work now

Have you fixed this yet? If not can you post your draw code so we can try spot something?

Re: 3D drawing back textuers come through front textures

No only 1.

Re: 3D drawing back textuers come through front textures

Roonda — Thu, 02 Jul 2009 18:41:02 GMT

That looks a little bit like Z-fighting. Do you render two cubes in each location perchance?

Re: 3D drawing back textuers come through front textures

BlackWolve — Thu, 02 Jul 2009 14:01:25 GMT

yeah i know ;)
the text is not correct positioned also atm.
but i want to fix the thingies on the bottom of the cubes.

You might want to put your 2D drawing code after your 3D drawing code, as currently all the messages are behind the 3D objects.;)

BlackWolve — Thu, 02 Jul 2009 13:33:18 GMT

Thnx for the quick reply
it worked perfectly.
See below
Better drawing

as you can see @ the bottom of the cubes there is sometimes some small parts missing
as i zoom in these things get smaller .
Any ideas on that?

1	public void Draw(GameplayScreen Game, Vector2 position, Boolean shadow)
2	{
3	float x = -6 + (Game.GameField.Width - 1 - position.X / 25);
4	float y = -13 + (Game.GameField.Height - position.Y / 25);
5	float z = 0;
6
7	Matrix crateTransform = Matrix.CreateTranslation(new Vector3(x-0.5f,y-1.0f,z-0.5f));
8
9	Matrix crateRotation = Matrix.CreateRotationX(0);
10	Model model = CrateModel;
11
12	DrawModel(Game, CrateModel, crateTransform * crateRotation, CrateTransforms, shadow);
13	}
14
15	private void DrawModel(GameplayScreen Game, Model model, Matrix modelTransform, Matrix[] absoluteBoneTransforms, Boolean shadow)
16	{
17
18	Game.ScreenManager.GraphicsDevice.RenderState.CullMode = CullMode.None;
19
20	Game.ScreenManager.GraphicsDevice.RenderState.DepthBufferEnable = true;
21	Game.ScreenManager.GraphicsDevice.RenderState.AlphaBlendEnable = true;
22	Game.ScreenManager.GraphicsDevice.RenderState.AlphaTestEnable = true;
23
24	//Draw the model, a model can have multiple meshes, so loop
25	foreach (ModelMesh mesh in model.Meshes)
26	{
27
28	//This is where the mesh orientation is set
29	foreach (BasicEffect effect in mesh.Effects)
30	{
31	effect.EnableDefaultLighting();
32	effect.Texture = SuperBrick ?
33	shadow ?
34	ShadowSuperCrateTexture : SuperCrateTexture
35	: ExplosiveBrick ?
36	shadow ?
37	ShadowExplosiveCrateTexture : ExplosiveCrateTexture
38	: shadow ? ShadowCrateTexture : CrateTexture;
39	effect.World = absoluteBoneTransforms[mesh.ParentBone.Index] * modelTransform;
40	}
41	//Draw the mesh, will use the effects set above.
42	mesh.Draw();
43	}
44	}
