What I want to do is read the faces(f), but they have "/" that I don't know how to remove? Basically what I want, is to get the faces number stored in a temporary variable. I have no idea how to do it in c++ fstream.
std::string text;
std::istringstream iss(line);
iss >> text;
// Easy part!
if (text == "v")
{
glm::vec3 currectPos;
iss >> currectPos.x;
iss >> currectPos.y;
iss >> currectPos.z;
filePos.push_back(currectPos);
}
if (text == "vt")
{
glm::vec2 currectUV;
iss >> currectUV.x;
iss >> currectUV.y;
fileUV.push_back(currectUV);
}
if (text == "vn")
{
glm::vec3 currectNorm;
iss >> currectNorm.x;
iss >> currectNorm.y;
iss >> currectNorm.z;
fileNorm.push_back(currectNorm);
}
// Last part, hard part!
if (text == "f")
{
// Face!!! :O
// This one here I am having trouble with
// How do I read it?
}

int i, j, k;
char c;
iss >> i;
iss >> c; // remove the /
iss >> j;
iss >> c; // remove the next /
iss >> k;
store the i,j,k somewhere and so on, then repeat as many times as needed.
