Guys, I'm trying to texture the triangle faces of a rhombus with this code:


public Object3D buildMarker(){
Object3D mrkr = new Object3D(8);
mrkr.setCulling(false);
float offset = MARKER_SIZE/2;

mrkr.addTriangle(new SimpleVector(-offset, 0,-offset), 0, 1,
new SimpleVector( offset, 0,-offset), 1, 1,
new SimpleVector( 0,-MARKER_SIZE, 0), 0.5f, 0);
mrkr.addTriangle(new SimpleVector( offset, 0,-offset), 0, 1,
new SimpleVector( offset, 0, offset), 1, 1,
new SimpleVector( 0,-MARKER_SIZE, 0), 0.5f, 0);
mrkr.addTriangle(new SimpleVector( offset, 0, offset), 0, 1,
new SimpleVector(-offset, 0, offset), 1, 1,
new SimpleVector( 0,-MARKER_SIZE, 0), 0.5f, 0);
mrkr.addTriangle(new SimpleVector(-offset, 0, offset), 0, 1,
new SimpleVector(-offset, 0,-offset), 1, 1,
new SimpleVector( 0,-MARKER_SIZE, 0), 0.5f, 0);

mrkr.addTriangle(new SimpleVector( offset, 0,-offset), 0, 1,
new SimpleVector(-offset, 0,-offset), 1, 1,
new SimpleVector( 0,MARKER_SIZE, 0), 0.5f, 0);
mrkr.addTriangle(new SimpleVector( offset, 0, offset), 0, 1,
new SimpleVector( offset, 0,-offset), 1, 1,
new SimpleVector( 0,MARKER_SIZE, 0), 0.5f, 0);
mrkr.addTriangle(new SimpleVector(-offset, 0, offset), 0, 1,
new SimpleVector( offset, 0, offset), 1, 1,
new SimpleVector( 0,MARKER_SIZE, 0), 0.5f, 0);
mrkr.addTriangle(new SimpleVector(-offset, 0,-offset), 0, 1,
new SimpleVector(-offset, 0, offset), 1, 1,
new SimpleVector( 0,MARKER_SIZE, 0), 0.5f, 0);
return mrkr;
}


The Object3D structure is fine, but I'm positive my U/V-coordinates are wrong because it is not showing it how I expected.
The texture is a 128x128 black png with a transparent triangle with its base running along the base of the picture and its top touching the middle of the picture's top border (sorry, I can't upload it right now). I wanna make a red, wireframed rhombus.
This is how I'm adding the textures I use to the TextureManager tm:


tm.addTexture("frame", new Texture("markerFrame.png"));
tm.addTexture("red", new Texture(8,8,java.awt.Color.RED));


And this is how I Multi-texture them:


tInfo = new TextureInfo(tm.getTextureID("frame"));
tInfo.add(tm.getTextureID("red"), TextureInfo.MODE_ADD);


Help, please!

And the result is... ??? You have to choose the texture coordinates in a way that in texture space (i.e. when projecting the triangle onto the texture), the coordinates actually do make sense.  Just draw it on paper. It's shouldn't be too hard to figure it out that way.

(Sorry for reviving this, but I have been very busy and could not come back until now)

What is the (0,0) point in a texture image? The upper-left corner? Or the bottom-left one?

I don't know from the top of my head. Just try it.

I did! Tried all four corners as origin and nothing worked.
So you say my code seems ok, but I still can't texture it right.
I'm lost...

...what the result you are getting? Can you post a screen shot?

Correction: Here is the screenshot.

Ok...and the texture looks like?

I don't know if you'll be able to see it.
http://imageupload.org/en/file/229807/c-documents-and-settingsf142247desktoppen-driveprojetosjpctdogfightcomdogfightresmarkerframe2.png.html (http://imageupload.org/en/file/229807/c-documents-and-settingsf142247desktoppen-driveprojetosjpctdogfightcomdogfightresmarkerframe2.png.html)

It's a black image with a transparent triangle.
This is the external texture. The red in the first picture is a solid texture I made with tm.addTexture("red", new Texture(8,8,java.awt.Color.RED));

I tried your code and your texture and everything is fine:

Maybe you've left some calcTextureWrapping-methods in?

WTF!!!

No, I did not use calcTextureWrapping-methods (at least not that I know of).

The declaration of the Red texture is in the main class, but there is no calcTextureWrapping there either.
I can post it here but I don't think that the problem is there.

You are not calling build() as far as i can see. Replace marker.calcNormals(); with marker.build(); to see if that helps.

Didn't work. Anything else? Want me to post the main class?

...that might help.

Egon? Please?

Sorry, i somehow missed your post. However, i don't see the problem...i hacked the main class to run without the required server stuff and the marker looks just fine IMHO. I've attached the texture that i used (it's a modified version of your texture, but i don't know anymore why i modified it).
