LOL, Rough Terrain!

Hey! My first poor attempt at a terrain generator

Can anyone point me in the right direction for terrain related stuff? Thanks, Scott

prolly not the best.. cause it''s not easy to change the size of the map yet but:

  
int generate_landscape() {
GLfloat x, y;
int i=0;

for (y=-size/2;y<size/2;y+=1.0f)
for (x=-size/2;x<size/2;x+=1.0f) {
p[i].x = x;
p[i].y = y;
i++;
}

for (i=0;i<size*size;i++) {
p[i].z = randFloat(-1.0f, 2.0f);
}


return TRUE;
}

int draw_landscape() {

int i;

glPushMatrix();
for (i=0;i<size*size;i++) {
if (i != 5 && i != 11 && i != 17 && i != 23 && i != 29 && i != 35) {
if (i != 30 && i != 31 && i != 32 && i != 33 && i != 34 && i != 35) {
glBegin(GL_QUADS);
glTexCoord2f(0.0f, 1.0f); glVertex3f(p[i].x, p[i].y, p[i].z);
glTexCoord2f(1.0f, 1.0f); glVertex3f(p[i+1].x, p[i+1].y, p[i+1].z);
glTexCoord2f(1.0f, 0.0f); glVertex3f(p[i+size+1].x, p[i+size+1].y, p[i+size+1].z);
glTexCoord2f(0.0f, 0.0f); glVertex3f(p[i+size].x, p[i+size].y, p[i+size].z);
glEnd();
}
}
}
glPopMatrix();

// water

glPushMatrix();
//glColor3f(0.0f, 0.0f, 1.0f);

glDisable(GL_TEXTURE_2D);

glBegin(GL_QUADS);
glVertex3f(p[0].x, p[0].y, waterheight);
glVertex3f(p[5].x, p[5].y, waterheight);
glVertex3f(p[35].x, p[35].y, waterheight);
glVertex3f(p[30].x, p[30].y, waterheight);
glEnd();
glEnable(GL_TEXTURE_2D);
glPopMatrix();

return TRUE;
}


this code will prolly get garbled, but what can ya do

I finally got it working with different sized maps! yes! a lot easier than i first assumed no wonder it''s hard to find a good tutorial on terrains.. dont need ''em
