 Posted: Sat Mar 12, 2005 7:10 pm Post subject: 2 .dmf format questions |
 |
|
I saw the other thread about this and it didn't answer my questions, so rather then interuppting that conversation, i'll start a new one.
Question 1:
Is there any way to take a level in DeleD with lots of seperate objects and convert it into 1 very large object. For now my parser is just doing 1 object and I figure that will make everything simpler.
Question 2:
When u get to the lines with the Polygon information: # of vertices,materialID,vertice index values,uv values. What order are the UV values? Like: u1, v1, u2, v2, u3,v3? or something else?
Thanks! |

1.) The "merge" function, select all objects and press merge.
2.) As far as i can remember, it is like this, u1, v1, u2, v2 etc.

| What language are you writing your parser in? Turning your whole map into one object won't be doing the program any favours for a few reason... is it c++? I can share my parser code with you if you want? |

Yes, its in c++, I just wanted to turn it into 1 object to test my progress and make sure it can handle a large object with a lot of polygons. It will be able to handle multiple objects and ill probably have a system where a certain object prefix on the name will make it a certain entity. Thanks for the offer though,  but I'de rather poke through it myself, might be a good learning experiance.
btw, what file IO library did u use, I used stdio only because I know it best and its worked pretty good so far, I've loaded the vertex and index information into the buffers and rendered the object in wireframe, I'm currently working on getting the textures on. But, if you know of a better file IO system, ill check it out. |

| I used fstream, stringstream and a char array. It's not done, but it's really easy to switch things up. Since I wasn't making an fps, it doesn't handle the lights, or materials with mulitple layers or stuff, but it's really easy to modify. I'll post it for you. |

You woulc have to play with this abit.. but I think it's easy to remove my stuff, and just plug in your own classes and arrays, it's commented what every line does. basically I grab a line of the file at a time, and I strtok() what I need outof it.
| Code: |
//DMF Loader
int c_map::LoadDMF(char *cFileName)
{
fstream fMap;
stringstream ss;
char ca[256];
char cMsg[256];
fMap.open(cFileName);
if (!fMap.is_open())
{
RichTextAppend("\nERROR: File not found.");
return false;
}
ss << fMap.rdbuf(); fMap.close();
//make sure this is a Deled map file
ss.getline(ca,256);
if (strstr(ca,"DeleD Map File") == NULL)
{
RichTextAppend("\nERROR: File not valid.");
return false;
}
//make sure this a 1.1 file
ss.getline(ca,256);
if (strstr(ca,"Version 1.1") == NULL)
{
RichTextAppend("\nERROR: Unsupported file version.");
return false;
}
//grab the map title, the ambient colour and the shadow opacity
ss.getline(ca,256);
strcpy(m_Name,strtok(ca,";"));
MakeAmbientFromHex(strtok(NULL,";"));
m_ShadowOpacity = atof(strtok(NULL,";")) /100;
//output the room name, ambient color and shadow opacity
sprintf(cMsg,"\nRoom Name: %s",m_Name);
RichTextAppend(cMsg);

I'de just like to let you guys know my parser is FINALLY complete. After taking a break for a while, I dedicated some hours from yesterday and today to get it done. It supports multiple objects, textures, lightmaps, you name it, it can probably do it. So thanks to all of you guys for answering my questions. There really is a great community here. I also have the source (poorly annotated and highly inefficient) but it works. 
Heres one question I have:
In Direct3D, as far as I know you have to put UV information inside of the Vertex structure that you use. So if 2 faces share a vertex and that vertex needs different UV information for each face, how would you do that?
I took the easy way out I guess and made each triangle its own Vertex Buffer and filled in the UV information. I KNOW that is not efficient at all, but it was the easyest way out.
Screen Shots:
As you can tell, I'm using DeleD LITE to make the lightmaps so the quality ... isn't quite what I expected, but what can you do. There are no other free lightmapping programs out there.
There wouldn't possibly be a way to get rid of the jaggedy edges w/o getting Pro with higher resoltion light maps would there? |

Glad to see you got things working, screenshots are cool!
To answer your questions:
- You need to duplicate your vertices in order to get multiple UV's for one vertice working. I'm guessing this is already what you're doing.
- Indeed, PRO solves the jagged edges for lighting, feel free to buy it!  |

I agree the screenshots are pretty cool, good job!
About the jagged edges: PRO doesn't neccesary render higher resolution lightmaps, as much as filtered lightmaps with smart (adaptive) individual per-face size. Giving you better lightmaps with a smaller total size.
Lite lighting really only is preview-functionality, in my opinion it is in no way suitable for any release, not only because of the jagged edges, but also because with any decent-size map the total lightmap size becomes huge pretty fast.
However, (and I am sharing some tricks of the trade here ), you might want to try setting the shadow opacity (scene properties) a lot lower, leaving you with barely any shadows at all and only subtle lighting, but no more jaggy edges. |
