Hehe that was the same problem I had when I started to learn about 3D programming...it took ages before I was sure that Vertices was plural of vertex...:D

matrix - an algebraic datastructure, a grid of columns and rows which is used in solving equation systems in linear algebra. In programming context matrices are mostly used for transformations made on objects in n-d space

vector - an n-tiple (an array of n elements) is a representation of displacement in n-d space

CPU - central processing unit

PCI - Peripheral Component Interconnect

I have added them to the post in the FAQ...thanks...;)

hehe nps, btw why does a vertex have a colour? or normal or texture coordinates? isn't that what polygons have?

No, a vertex is a point with aditional information about the point

Code example:

Code:

---

Struct Vertex{
  D3DVECTOR3 vPosition; //Point
  DWORD dwDiffuse;        //Diffuse vertex color
  D3DVECTOR3 vNormal;  //Vertex normal
  FlLOAT u, v;                  //Texture coordinates of vertex
}

Let me also add a picture to that one....2 seconds...;)

Look at all those nice colors and all of them have an explenation...:D

wait a minute.. does that mean that a vertex cannot be shared between polygons? and why have normals on the vertices, when you can have them in the polygon?

btw nice colours ;)

The face normals are calculated automaticaly by graphics APIs like DX. They are used for flat shading...you know when you can see all the faces of all the triangles.

The vertex normals are used to make gouraud shading. So objects looks round, if an other triangle is attached to that one, you have to claculate the vertex normals again, so they are the average of the vertices for the triangles using the save vertex. So yes a vertex can be shared.

I know, this is the way it is going to be from now on....

ah.. gotya, so with gouraud shading the shade is interpolated across the triangle?

I like it that way ;)

Here we go, got a Script done for Viewing the definitions.
http://www.ElectromanUK.com/Definition.php?word=AGP

So far I have only added the AGP one, I'm just about to add the others though. I still gotta make a editing script but I'm not sure if I should make it so it saves the old version incase someone goes though it making a mess of the definitions.

The page generated could do with some kind of background as well if anyone wants to make one for it or has any ideas?

BTW its case insensitive as well :D.

Here we go, to add a definition use this page: http://www.ElectromanUK.com/AddDefinition.php

I've added all the definitions you have already put in the FAQ BTW ;).

I will put it in the FAQ when I get hope today....nice job.

And I will add:

VS
PS
HLSL

to it too....;)

If you want to view all the definitions abit like how you've done in the FAQ then heres a link:
http://www.ElectromanUK.com/ListDefinitions.php

I just added the FPS definition to your DB, however you're using AddSlashes() which is not necessary in that Form. Well you can see the result...

Thanks for adding it. We have been pretty lazy updating that dictionary. Electroman will probably have a look at his PHP skills when he have the time to it.


Thanks

Don't forget to add some OpenGL stuff there :)
If you guys never found my site by telepathy, here it is:
http://www.crystal-rain.com/libsapng/index.htm

I had that page bookmarked a while back. Before some reformating...:)

And there is some OpenGL links in the FAQ. But we havn't found too much on OpenGL and VB. Most of it is in C++.



PS: Me and Electroman where betting if you where going to post the png lib here or not. And I won..:)


I am adding it the faq.



ØØ

Well, you know me too well, I'm a hipocryte that can't stand but advertising my ill-coded Visual Basic work. Hurrah! :)

We all do that..:)...and now there is your own sub section where you can post code samples and full games here too...;)


BTW, we should probably add to the FAQ that VC++ 6 is no longer compatible with DX. ANd that the new decemper version won't work, so they have to use the summer edition.


Will try to find some links.


ØØ

I think a tutorial on how to *set up* a C++ environment with OpenGL/DirectX/what have you would be a better idea -- many people don't have a clue how to do that, and get turned off when they are unable to compile the sample code.

Here is a start..::)

http://vbforums.com/showthread.php?t=311798



and I am on about making my own DX web site where I have lots of tutorials, and that is the first one about DX. I have all ready written 3 math for DX and am currently writing on my 2-3 first DX tutorials. But I havn't gotten to start on the web site. Electroman said he would help me with that, and a friend of mine said he was going to make a logo similar to the XNA logo. So it is under it's way...:)



ØØ

So, where should I post a tutorial if I have one all made up?

Brad would like you to post it in the Utility - Tutorial section:

http://vbforums.com/forumdisplay.php?f=61

I have often posted my tutorials there, and then linked them from the FAQ. But in my sig, I have the link to the original tutorial that is posted on an other site. But Brad doesn't like it...:(


ØØ

Gah :( Look what I've gone and done, damn. Well, I'll ask for it to get moved when it's actually done -- I'm on linux and it was all from memory anyway :o

Electroman just said on MSN that he was going to PM you and ask if you wanted it to be moved...:)...so I guess we got the answer there. He will do it, and we can put a link in the FAQ.

Heya!

I've seen "Electroman's 2D Engine" in the FAQ section, looks like I did something similar. I'd suggest putting the YDCore in the FAQ, too. It's a Open Source DX8/Winsock/etc. framework/engine with integrated TileMap/Set and Sprites.

Rinnku: http://ydk.yhoko.com/ydcore

Thanks!

I've added it to the list, not had a chance to look at it yet tho. Thanks :)

someone should make a game tutorial using DX. that would be fun

Yhoko's engine link is bad :(

It says that the file is not found on the server

To Electroman: Nice engine, you have done what I have done with the images. My engine stores images and a large vertex buffer inside its-self so that the developer can create objects that with different names but the objects will still render fine as the objects that the developer refers to are just references to vertices

My engine is attached, and incomplete.
