    OpenGL GLUT 3D?

    I've been learning GLUT/OpenGL for the last few days doing simple stuff like 3D cubes and the like... but i was thinking... how do you make complex objects... is there a file format i can use? how is it done?


    thanks

    well first you find the format definition, then the rest should be obvious, just read whats there(this can be very complex)...

    http://www.wotsit.org look for some formats

    read over the format and see how the data relates to points, and polygons, texture ect...

    use the data in the file to draw them like you would normally draw the objects,


    like a polygon, maybe
    depending on how your(the) code orginizes the data for drawing,

    Code:
    for(int i = 0; i < number of polygons;i++)
    {
        glBegin(GL_POLYGON);
            for(int j = 0;j < number of polygon vertices;j++)
                 glVertex3fv(polygon[i].polygonvertice[j]);
        glEnd();
    }
    keep in mind this is just an example.

    im not really sure as to what most popular, .3ds?

    i used .lwo 's since LightWave is what i need to use for my purposes... im still working on the loader for them, fairly close now, it's a pretty complex format. and then theres still the LightWave scene format...

    try asking the guru's at http://www.opengl.org , they might be able to helpm more.

    .md2 and .ms3d are the easiest to code for (.md2 is the Quake II file format and .ms3d is produced by the shareware program Milkshape 3d). If you go to http://nehe.gamedev.net/ you will find tutorials in both of these formats.
