void renderScene()
{
float x,y,z;
ifstream fin("c:\\export.txt");
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glBegin(GL_QUADS);
while (fin.good())
{
fin >> x;
fin >> y;
fin >> z;
glVertex3f(x,y,z);
}
glEnd();
glutSwapBuffers();
}
for me it looks ok, but really, some faces aren't rendered, and I don't know why... Here is how it looks (it is supposed to be without these holes, full smooth shape).

opengl my own model format loading

I made something wrong probably... I wrote an exporter for blender which exports vertexes, every face like:
1.0 0.5 0.7
-1.0 -0.2 0.9
0.7 0.5 0.3
and I made a GLUT program to load this model. here's the drawing part
Are you sure blender exports your models to triangles?
It is possible that it exports it as faces , consider the following two quads
// Quad one
a
b
c
d
// Quad two
z
x
y
u
// Quad three
f
..
Can also double to mean
// Triangle 1
a
b
c
// Triangle 2
d
z
x
// Triangle 3
y
u
f
Also make sure backface checking is off!

I was going to say something similar, except that for performance reasons, you may want to make sure all the vertices are wound correctly rather than turning backface culling off.

Blender exports as quads, exactly as I posted glBegin(GL_QUADS)... how do you turn backface off?
EDIT: Nevermind, I fixed it. The problem was with my exporter, I was using old version and he exported just vertexes, not faces... ;/
*problem solved*
