我正在尝试编写一个 3D 模型,我正在从 .obj 中读取它的所有内容都使用标准茶壶模型,因此我决定为实际任务创建一个宇宙飞船。然后我用茶壶文件更改它,然后将数组更改为足够大,以便在尝试运行我遇到未处理错误访问冲突错误的程序之前适合顶点和顶点法线等。以下是该程序使用我必须使用的 glut 库的所有代码..

作为旁注,我正在尝试制作它,以便我的相机作为原点围绕宇宙飞船移动。

#include <windows.h>

using namespace std;

camera cam = {0, 0, 5, 0, 0, 0, 0, 1, 0};


point3D v[162] = {};

void init()

glClearColor(0.5, 0.7, 0.0, 1.0);

glLoadIdentity();
glFrustum(-1.0, 1.0, -1.0, 1.0, 1.0, 500);

}

void display()

glClear(GL_COLOR_BUFFER_BIT );
glMatrixMode(GL_MODELVIEW);
glLoadIdentity(); // reset the matrix
gluLookAt(cam.pos.x, cam.pos.y, cam.pos.z,

int two = f[i][1].x;

getline(stream, temp, '/');
f[numFaces][count].x = atof(temp.c_str());
getline(stream, temp, '/');

}

glutInit(&argc, argv);
glutCreateWindow("rendering a spaceship");
glutDisplayFunc(display);
glutSpecialFunc(specialKeyboard);
glutKeyboardFunc(normalKeyboard);

init();

glutMainLoop();
}
}

确切的错误如下“3dsassignments.exe 中 0x779815de 处未处理的异常:0xC0000005:访问冲突读取位置 0x40000010。”
