Question

我最近一直在搞乱OpenGL和c ++（使用FreeGLUT和GLEW）并开始尝试从3DS Max 2014导入.obj文件。如果我手动输入顶点和索引但是，当试图获取时，一切都很好他们从一个文件我得到奇怪的数字。当获得指数而不是1时，有1000而不是3而有3965，当有12时是1212（有一些和三个等等但有时它们是随机的）

以下是我用来导入的代码：http://pastebin.com/1ds6fgj9

或

std::vector<std::string> Object::split(std::string str, char splitter){

char charText[1000];
int number = 0;
int numberOfWords = 0;
char current[10][100];

std::vector<std::string> tokens;

strcpy(charText, str.c_str());

int size = sizeof(charText) / sizeof(*charText);
//std::cout << size << " size\n";
for (int i = 0; i < splitter; i++){
    if (charText[i] == splitter){
        tokens.push_back(current[numberOfWords]);
        numberOfWords++;
        number = 0;
    }
    else{
        current[numberOfWords][number] = charText[i];
        number++;
    }
}

return tokens;
}

Object::Object(std::string fileName, Vector3f pos, Vector3f rot, float Size, Vector3f color){
Position = pos;
Rotation = rot;
size = Size;



colors = color;


std::string data;
std::ifstream file(fileName);
std::string line;


Vector3f _verts[1024];
int noVerts = 0;

unsigned int _inds[1024];
int noIndices = 0;

while (getline(file, line))  // same as: while (getline( myfile, line ).good())
{

    char charText[1024];
    strcpy(charText, line.c_str());



    if (charText[0] == 'v' && charText[1] != 'n' && charText[1] != 't'){

        std::vector<std::string> splitLine = split(line, ' ');
        _verts[noVerts] = Vector3f(atoi(splitLine[1].c_str()), atoi(splitLine[2].c_str()), atoi(splitLine[3].c_str()));

        //std::cout << "Vertices Number:" << noVerts << " x:" << _verts[noVerts].getX() << " y:" << _verts[noVerts].getY() << " z:" << _verts[noVerts].getZ() << "\n";
        noVerts++;
    }

    if (charText[0] == 'f'){
        std::vector<std::string> splitLine = split(line, ' ');

        for (int i = 0; i < 3; i++){

            std::vector<std::string> ssl = split(splitLine[i+1], '/');

            //std::cout << atoi(splitLine[i].c_str()) << "\n";

            std::cout << i << ": " << atoi(ssl[0].c_str()) << " " << atoi(ssl[1].c_str()) << " " << atoi(ssl[2].c_str()) << "\n";

            _inds[noIndices] = atoi(ssl[0].c_str());
            noIndices++;
            _inds[noIndices] = atoi(ssl[1].c_str());
            noIndices++;
            _inds[noIndices] = atoi(ssl[2].c_str());
            noIndices++;

            //std::cout << "number of indices:" << noIndices<< "\n";
        }

    }


}

verts = _verts;
inds = _inds;

SizeV = sizeof(verts);
SizeI = sizeof(inds);



noPoints = SizeI / sizeof(*inds);
length = SizeV / sizeof(*verts);


Matrix4f posM, rotM, sizeM;
sizeM.InitScaleTransform(size, size, size);
rotM.InitRotateTransform(rot.getX(), rot.getY(), rot.getZ());
posM.InitTranslationTransform(pos.getX(), pos.getY(), pos.getZ());

M = posM * rotM * sizeM;

for (unsigned int i = 0; i < length; i++){
    verts[i] = _verts[i];
}


}

我认为在阅读文件时我的代码是错误的，但如果不是只是要求查看我的其他代码。

[编辑]

它为所有obj文件执行此操作（未尝试使用其他程序导出，并且我尝试过的obj文件只有很少的面）。

.OBJLoader，怪异的索引号
