I've been here long enough, about time I post something. Smile

Just some Work in Progress shots of a small, very low poly room.

Embarassed

Well... low poly when I delete all those back faces! I think I need to replace the floor, I think it clashes really bad with everything else.

I like it

,it looks like you hard work is paying off.

Looks very nice indeed, it has a realistich atmosphere. Smile

Do post more! Wink

Did you guys get the mail I sent out to you about this yesterday?

Daaark · Posted: Sun Mar 13, 2005 9:42 am Post subject:

I had a lot of trouble with my face normals yesterday. I finally got them to face the right way by negating all of them. I'm not sure if I'm doing something wrong, or if the vertices are wound in the wrong order in the dmf files.

You need to normalize the normals after doing the cross product. Well, you don't really need to, but it should be normalized for OpenGL-Lighting, etc.

I was normalizing them too. Smile

But then they get messed up again. So I removed my vNorm.Normalize() line, and did it by hand... and still the wrong results... Confused

So I just turn on glEnable(GL_NORMALIZE); and it's working for now. Smile

Something I will solve later.

Cool screenshots! And I think you are right about the floor, at least make it it a little more low-contrast (white less white, black less black) and add some scratches. Other then that, very(!) interesting project! Cool

About the winding, DeleD uses clockwise winding for front facing polygons. If you use OpenGL, glFrontFace(GL_CW) will do the trick. If you prefer to use counter-clockwise winding in your project, simply reverse the winding when loading in the polygons.

Even though the OpenGL default is CCW frontfacing, I wouldn't exactly call CW 'wrong'. That makes just as much sense as calling either LHS or RHS wrong. Very Happy

Daaark · Posted: Sun Mar 13, 2005 11:16 am Post subject:

I didn't mean to imply that it was wrong. Smile

But I figured you would use ccw with Deled since it's done with OpenGL.... is this written anywhere?

How do I make them ccw? Do I just reverse v3, v2 and v1?

I may change the floor to blue carpet.. right now working on bottle textures for the bar shelf.. and something for a fireplace. The floor texture did have some variation in it. It was subtle and Deled's texturing filtering options is smoothing it all out. Smile

Here's today's progress. Smile

After spending some time on google images, I found a nice fireplace to model my own after. I'm still only at 702 polygons, and that's only because I haven't deleted the un-needed faces. I think the back shelf needs work.

Better all the time Very Happy

Nice one

Thanks granada.

I solved the winding problem by storing the indices in reverse as I read them in. Smile

I guess sometimes, some things ARE THAT EASY! Laughing

No more negation. But even through I normalize manually as I create the normals, I still have to enable GL_NORMALIZE for everything to light properly. Crying or Very sad

Paul-Jan · Posted: Sun Mar 13, 2005 3:26 pm Post subject:

Cool, love the new screenshot! (although the lighting really looks like it is rendered by Lite Wink

I would suggest making the shadows a bit less opaque)

Paul-Jan · Posted: Sun Mar 13, 2005 3:36 pm Post subject:

Just noticed how you wrote "I was normalizing them too. But then they get messed up again". That suggests a bug in your normalization code, if you could post/mail it we could have a look.

The normal-generation posted above looks ok, although if you really need to negate the vector you could simply reverse the arguments in the initial 2 edge-vector subtractions instead of negating the whole thing in the end.

Daaark · Posted: Sun Mar 13, 2005 3:49 pm Post subject:

I don't have to negate them now, as I reversed the winding back to CCW by reading the indices in 3,2,1 instead of 1,2,3. Smile

(as posted above^^^)
