[Noorez K. <coo...@ho...>]

What is the function that ejects the cd? I tried looking but i couldn't find 
one.

[Dev-C++] MCI

[Noorez K. <coo...@ho...>]

What include files do you need to use the MCI. I tried searching but i 
couldn't find it anywhere.
-I am using the dev-cpp for my programs.

[Dev-C++] Questions

[Noorez K. <coo...@ho...>]

1. Is there anything in C++ that can let you check what drives are valid on 
the computer?

2. How do you make a program automaticly start up when the cd that contains 
it is inserted into the drive?

[Dev-C++] polygonsoup

[<mi...@al...>]

What I do is that: I scan a volume by an octree; to decide if one cube has
to be subdivided I look for the values on the vertices of the cube.
At last level of detail, I have nodes-cubes and I know their configuration,
so with marching cubes I find the triangles that aproximates the surface
intersecting the cube-node, and I store the vertices of these triangles 
in
my list.
So These triangles form a 3D volume, but the only information I reach 
about
a 3D point-sampled is if
this point is inside or outside my volume, so I haven't a scalar value 
that
gives me possibility to interpolate them and so to smooth the volume.
(The good think is that the triangles are almost of the same size.)
Perhaps the better think could be storing topological information while
building the octree.


Unfortunately ... I don't know nothing about 'scanline conversion'.

Thanks for the suggestion about 'winged edge structures', i will look around
for it, 'till now I don't understand how I can know, during my marching 
c.,
if two triangles share one edge

hi,

little prehistory:
worked with wx 2.4.2.(devpack), but an error in in wx forced me to build it

this was kind of amazing
(->

and took me about 3 month, solved it by the linking params:

well, use dev-cpp 4.9.8.10.(gcc version 3.2 (mingw special 20020817-1), GNU

and I can't debugg it anymore, nothing will happen:

with it go's an error wether in wx or my app: 'Can't verify memory struct -

but I can debugg non wx apps, so I guess, the linking might be the problem.

any ideas?

Re: [Dev-C++] DLLWrap - Line Too Long

Run the command manually - or edit the make file - but specify *.o instead

[Dev-C++] DLLWrap - Line Too Long

[<A_B...@gm...>]

HI,
I whant to compile a dll project called Irrlicht.
It contains 111 file which all compiles right to object files.
But if dllwrap tries to link all object files together it stops with an
"Line Too Long" error !!!
My system is "Win2K-sp4", therefor the command line for dllwrap is to long
for the system...
Even if I rename all files to the shortest possible names, the command line
would be to long...

How can I solve this problem ???
Maybe there is a way to increase the length for the command line ???
Or someone has another solution to this ???

CU, Acki

Re: R: Re: [Dev-C++] polygon soup

[Per W. <pw...@ia...>]

Ah, I missed the info about no holes and request for smoothing.

Do you just want to hide the facettes of the flat triangles, or were you
interested in either replacing the triangles with fewer primitives, or
with primitives of higher orders - such as nurbs or bezier patches?

Anyway, a linked list is not a very good way of storing a triangle
geometry without holes in it. It is very, very expensive to locate
triangles sharing vertices or edges. You might look around for winged edge
structures, i.e. where you store edges and for each triangle keep
track of it's tree edges, and for each edge keep a pointer to
the two triangles sharing the edge. Then it is trivial to walk from
triangle to triangle when evaluating bumpines etc. Also, you will then
only need to store coordinate and normal information once for each
vertice, instead of the list which store everything six times on
average. My storing a vertex only once, it is also simpler to perform
"easing" of the geometry by filtering the vertices to reduce
high-frequency noise from a sampling process.

Re: R: Re: [Dev-C++] polygon soup

[Per W. <pw...@ia...>]

In this case you store the triangles in a long list. However, you don't
mention if there are any geometric properties of the loaded trianges. Are
they completely random (in x, in y, in z, in size, in normal directions
etc), or is there some important geometric properties to make use of
when processing them?

What do you expect to get out of your work? A two-dimensional "blanket" of
z-values or are you trying to create the 3-dimensional (convex or
non-conves) of the triangles?

If the triangles are completely random and with not too large size
differences, an easy solution is to just perform ray-tracing - or actually
ray casting - without any perspective transform for the rays, i.e. all
rays parallel. A simple BSP tree - or maybe an octree - would allow quick
intersection tests by reducing number of triangles to test.

Scanline conversion might also be used to process the triangles. However
both scanline conversion and ray-tracing will generate a blanket of fixed
spacing - of course possible to postprocess later.

It is also possible to use space subdivision - such as BSP trees to
directly emit polygonals representing the blanket. If the original "soup"
of triangles have random z coordinates (or maybe "r" coordinates if this
is a problem in polar space) this will require a number of vertical
(radial) polygons to handle steps in the z (r) dimension.

This is the case of what I call 'One Way Linked List'.
For example:
http://www.faqs.org/docs/thinkjava/chap14.htm
this is a Java, but you might get the idea

C++ linked list tutorial

and another one

Geometry itself does not affect that linked list, because every
element is one entity (independent of others).
Rendering it depends on the engine you use.

R: Re: [Dev-C++] polygon soup

[<mi...@al...>]

Hi Per,
I am 'that' Michele that makes some strange questions, unsubscribed for 
a while...
happy to meet again your attention.

The polygons are triangles stored in a structure like this:



struct element{
float vertex[3][3];
float normal[3][3];
element *newElement;
}

in a 'record'.

element *one,*start=NULL;

//If a new triangle comes
one=new element;

one->vertex[0][0]=...
...
one->element=start;
start=one;

There aren't holes in the geometry (for now), but I would like to smooth it.
thanks.

[Dev-C++] read system call

[A.Bhuvaneswaran <bh...@sy...>]

Hi,

I am using win xp home edition.

I am new to windows. I am trying to read data from a binary file using
open, lseek & read system calls. But, read returns 0 bytes at certain
point, even though it has not reached the eof.

For example, if the file size is 400k and if i try to read from 2k to
300k, 1k at a time, read returns 0 (indicating eof, right ?) after
reading 51k.

I have tried the same code on gnu linux and it works perfect.

Could you please let me know what am i doing wrong over here ? Googling
and search in the archive does not help.

TIA.

I will be glad to submit repeatable tiny sample code, if required.
