Hey insanity , and don''t forget we where supposed to look dark vertex in action b4 a few months . However , if ur on a redesign phase just keep up , it''s looking cool .

Joe, thanks again. I'll have a "still in progress" version in the next two weeks, I promise.

Bas, I just implemented grids again, and I still couldn't find a better system than the crappy one I was using before. All I'm doing is checking the window's state, deciding whether to create a grid in the x = 0, y = 0 or z = 0 plane, then just creating a grid around the user's current position. I do a little math to ensure that the grid doesn't move just with the user, then I just render it. I'm still doing it every frame. If you've thought up a better system, I'd love to hear it...

By the way, Bas, if it isn't too much trouble, could you email me those MFC/OpenGL documents? The programming world is moving away from C (which has been my primary language since I learnt it about three or four years ago), and towards C++ and MFC. I'm going to have to learn those two sometime, so I might as well start now . I'm going looking for some C++ and MFC books this week or next, any suggestions?

get
Programming Windows with MFC Second Edition
from Jeff Prosise

the best mfc book i could find i use it as a references

www.codeproject.com
www.codeguru.com

those sites have fantastic code samples to look at


ill send you the files later i need to go now cause we get OIL before bush invades iraq *G*


maybe you want to have a look at the creating 3d tools tut on gamedev thats what i have used to get started with mfc

as long as you use the class wizzard you shouldn t have a problem with control handling


about the grid

i fucking hate the grid what i am doing is get the scroll pos 0-<2^16/2
doesn t work for high values somehow

then i get the width/2 of the view
subtract it from the scroll possitions and then check the result

16 is grid space
d=min.x/16-(int)(min.x/16);
nx=(int)(min.x/16);
if(d>=0.5)
nx++;

once you have got that for Y as well you get the distance between screen center of the view and nx / ny
now check whether it is greater than >0 and < screenwidth/screenheight

and now render

you can use this procedure to perform this snap to grid feature as well but you need to take care of the zoom modi

1,2,4,8,16,32,64,128,256,512,1024,2048,

if there s mistake in my theory please point it out i thought about this the entire day
til now i have fixed all the problems mfc caused when using opengl
slow progress but there s nothing worse than a bug right at the beginning that ruins all the effort you put into your app

by the way , insanity and basior . In your editors , is zooming smooooth or there are 8 zoom modes for example ?

Well, in DarkVertex, there are five zoom modes, which you switch between using a window menu (I''d use the mouse wheel, but there''s just no support for it).

if you use progressiv zoom you will get trouble with your grid it looks ugly
download worldcraft and test it hehe

What do you mean ? I thought worldcraft did not perform smooth zooming . I think there is a limited number of zoom modes available . (unless i am missing an option wich i could enable or disable) .

@ Basiror, thanks for the offer, let me work on it a bit so im not one of THOSE people, hehe.

I have WorldCraft, and it uses the mouse wheel to smooth-zoom. It''s a good system, but I can''t use it, because VB doesn''t support the mouse wheel. Anyway, I designed the grid so it wouldn''t look too bad zoomed...
