« on: March 07, 2011, 06:35:48 pm »

hey where can i find the right GLM(the one that loads .obj files to, opengl?)

getting lost trying to find the right one xD

EDIT: Im on Windows Vista(home)/windows 7(school)

General / Bad rendering?

« on: February 28, 2011, 07:56:59 pm »

ok i loaded a smaller model, and i noticed this

http://img27.imageshack.us/i/glitchrealized.png/


if you notice, it shows only one triangle on the mesh(the big triangle that is supposed to be a square.

also it has jagged edges on it, thats not supposed to be there.


im thinking that maybe theres a glitch with the face loading but im not sure

anyone?

And if you comment out these lines?

Code: [Select]

glEnable(GL_POLYGON_STIPPLE);

same problem

General / Bad rendering?

hm...its a bit hard to explain


basically when i go to run my game, the model looks badly rendered..


thats supposed to be a model, but it looks like its graphically bugged..


heres some code that i used that involves that model:

Code: [Select]

#import ".\WorldMap3Dv1.h"
glEnableClientState(GL_VERTEX_ARRAY);
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
glVertexPointer(3, GL_FLOAT, 0, WorldMap3Dv1Verts);
glTexCoordPointer(2, GL_FLOAT, 0, WorldMap3Dv1TexCoords);
glDrawArrays(GL_TRIANGLES, 0, WorldMap3Dv1NumVerts);


at first i thought it was the graphics card not liking it, but when i used this on my main computer it did the same thing..

any ideas now?


Theres spaces between the model, and alot ._.

Extra details: I used an obj2opengl.perl to load the obj file into a header file(.h)

its probably something wrong with that..

General / Parsing an OBJ

« on: February 19, 2011, 06:44:28 am »

hey im using Perl to convert my obj files so thats not a problem.


BUT

when loading the model, i cant see it ._.


these are what i have used for this

// set input data to arrays
glVertexPointer(3, GL_FLOAT, 0, WorldMap3Dv1Verts);
glTexCoordPointer(2, GL_FLOAT, 0, WorldMap3Dv1TexCoords);

// draw data
glDrawArrays(GL_TRIANGLES, 0, WorldMap3Dv1NumVerts);


also
glEnable(GL_VERTEX_ARRAY);

is there something else im missing?

also i know that its loading because it slows everything down once i enabled

General / Parsing an OBJ

« on: February 18, 2011, 02:37:28 am »

i have tried these before(for 2 hrs straight) and everything i tried ended in an undefined error...

i like this one though(http://kixor.net/dev/objloader/)


what should i be linking in this? ._.


also i want it where i dont have these files in my directory...

is that even possible?

if not then ill *sigh* deal with it


EDIT: tried putting in the directory, didnt work >_<


this works: objLoader *World = new objLoader();
then i get undefined for: World->load("test.obj");

the error says: |undefined reference to `objLoader::load(char*)'|

im not delaying my project for another day........

hey ive been looking around for a while(3 days) and i cant seem to fined a good way to load my .obj mesh into my c++ game....


does anyone know how to parse an obj file or know any tutorials that can help me?


that would be very nice


what im looking for is maybe a way to get started at least(like an outline of some sort)

thanks in advance

Hiura, im having a hard time figuring what you said out...


this is what i got so far..

Code: [Select]

GLuint _texture[2];
    sf::Image ictexture[2];
    sf::Image itexture[2];
    itexture[0].LoadFromFile("Block.png");
    itexture[1].LoadFromFile("Cursor.png");
    ictexture[1].Copy(itexture[1],10,10,sf::IntRect(0,0,10,10),true);
    ictexture[1].SaveToFile("Graphics/Texture/texture1.png");
    _texture[0] = LoadTexture(itexture[0]);
    _texture[1] = LoadTexture(ictexture[1]);

when doing this i get Console errors saying:

Failed to write PNG image. Reason: image width or height is zero in IHDR
Trying to access the pixels of an empty image<<<i think this is from opengl..

nevermind that, forgot image.create()

scratch that other question if it doesnt make sense ._.

how bout a way to use only PART of an image that is loaded for a texture?(width 50 height 50) and using only(25x25) of the image


is THIS possible?

hey ive been wondering something..

is it possible to load a sprite as a texture(i got it to work as an image before)

what im trying to do is use a subrect of that image(say its 30x15 and i wanna use ponly 15x15 of it)

heres what i got so far:

Code: [Select]

GLuint LoadTexture(sf::Sprite image)
{
    GLuint Texture;
    glGenTextures(1, &Texture);
    glBindTexture(GL_TEXTURE_2D, Texture);
    gluBuild2DMipmaps(GL_TEXTURE_2D, GL_RGBA, 17, 22, GL_RGBA, GL_UNSIGNED_BYTE,image.GetImage().GetPixelsPtr());
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR_MIPMAP_LINEAR);
    return Texture;
}

and in main...

Code: [Select]

GLuint _texture[2];
    sf::Image itexture[2];
    sf::Sprite stexture[2];
    itexture[0].LoadFromFile("Awesome.png");
    itexture[1].LoadFromFile("Graphics/Player Sprite.png");
    stexture[1].SetImage(itexture[1]);
    stexture[1].SetSubRect(sf::IntRect(0,0,17,22));
    //_texture[0] = LoadTexture(itexture[0]);
    _texture[1] = LoadTexture(stexture[1]);

hopefully the code can give you some vision of what will happen

ok what you said is very vague to me(might just be me ._.)
and when you say that PNGs work the same, in the tutorial im using, it doesnt let me load other than BMP

also is there seriously no way to use a SFML sprite/image instead?


just something to fill this in:

Code: [Select]

glTexImage2D(GL_TEXTURE_2D,0,GL_RGB,image->width(THIS),image->height(THIS),0,GL_RGB,GL_UNSIGNED_BYTE,image->pixels(AND THIS));

hey im at a point where im using textures.


is there a way to use a SFML image/sprite for the texture?

if not then what is a way to laod a PNG? (i like PNGs xD)

the tut i found is only BMP
