And again I've got alot of question marks :lol:

?????????????????????????????????????????

I am really noob at compiling :P
Deus said I should use Cygwin to start with..
(cygwin is a CMD like window where you do the compiling and testin/exectuting)

And I am using quite a few includes :)

Code: Select all

#include <stdio.h>
#include <math.h>
#include <algorithm>
#include <stdlib.h>
I need those to make it run :)

And what is *nix!!!???

EDIT:
I get the error when I got to many and to big variables...

Now I get to post a bunch of ?????'s too :)


*nix = Linux, Unix

You're using CYGWIN under windows - cygwin is a Linux-like environment for Windows.

It means you are able to use, for example, the bash shell, and gcc (which is what I'm guessing you're using to compile).

As for your problem, I bet you're passing around data using variables - causing the stack overflow. Look into what pointers are, and use them (a pointer passes the *memory address* of the data, rather than the data itself)

Well, with Nick's help and a bit oodmb's I managed to fix my "mem/array" issues that I had..
All is working when ran inside of Cygwin :D

Little rotation animation (.mp4)
(the diffuse material is a rude 'fake' kinda... but it works^^)

But! When I compile this to a .exe file it crashes only moments into
the actual saving of the pixels in the bmp save part.. :?
Which I really cant understand... :(

Oh well. I think I'll be able to fix it some time :lol:

About your crashing issue, maybe you don't have any halt commad after your main loop? If you just have return 0; at the end of your program, then it will close. It doesn't crash, it just closes.

well, I do get the "blah bla Has to be closed.. blah blah" Windows Crash Messenge :)
..removing return 0; does not help..
I don't know any halt commands, but I didn't need that for anything else anyway..

Ehm...

You've come a long way from outputting some lines to a webbrowser.

Hehe, yes^^

And now I have the obj import/parser working! Image
Ofcourse with some help, hehe Image


A render of a squid I made some months ago: Image
The material is a kind of depth shader..

"Logfile"

Code: Select all

W: 800
H: 450

--bulding mesh
  --reading..
  --done..
  --Tris: 82368
  --Verts: 41210
--Drawing mesh pixels

--Saving bmp
  --setting headers
  --setting pixels
--Done saving bmp

OBJ Time: 2.000000e+00
Render Time: 0.000000e+00
Total Time: 2.000000e+00
Still working on the timers.. hehe
Not too accurate


Back to coding and reading Image Image

It's a beautiful thing :D Well done. And you got the perfect test model for it, too.

Thank you, Dave :D

Today I worked on two file parsers,
one for a Config/Ini File and one for the Scene File :)

The config file looks like this:

Code: Select all

#True Ignition Configuration File

#General
-sceneFile 'C:/trueignition/scenes/testfile.ti';
-outPutImage 'C:/trueignition/ti_img01.bmp';

And the scene file format looks like this:

Code: Select all

//Scene made by Arne OOG

globalSettings
    width '800'
    height '450'
;

cameraObject
    position '0.000 0.000 23.000'
    rotation '0.000 0.000 0.000'
    focusDistance '23.000'
;

materialShader
    name 'default'
    color '0.855 0.251 0.172'
;

polygonMesh
    filePath 'C:/trueignition/scenes/squid.obj'
    material 'default'
;

Some stuff in the scene file still don't work, but all file stuff is 8)
Also the parser is abit buggy at the moment :?
...and as you can see, I will call the renderer "True Ignition" :P

I think I actually can make my v0.0.1 release date :lol:

Cheers!

good job
