我有以下的頭文件:'沒有指定類型' 在C的誤差++
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <stddef.h>
#include <GL/glew.h>
#include <GL/glfw.h>
#include <glm/glm.hpp>
#include <glm/gtc/matrix_transform.hpp>
#include <glm/gtc/type_ptr.hpp>
#include <stdlib.h>
#include <vector>
class Sphere
{
public:
Sphere();
int count_sphere_vertices(int ,int, int);
Vertex* create_sphere(int ,int , int);
};
現在當我編譯我的代碼
我得到這個:
Sphere.h:18:3: error: ‘Vertex’ does not name a type
Sphere.cpp:48:1: error: ‘Vertex’ does not name a type
和
test_1.cpp: In function ‘int main()’:
test_1.cpp:318:38: error: ‘class Sphere’ has no member named ‘create_sphere’
什麼是
'頂點'沒有指定一個類型
是指?爲什麼我得到
'類球形' 沒有成員名爲 'create_sphere'
因爲我有這在我的Sphere.cpp:
//Calculating points for the sphere (the algorithm is implemented here)
Vertex* Sphere::create_sphere(int dtheta,int dphi, int no_vertices)
{
GLdouble x,y,z,x2,y2,z2;
GLdouble magnitude=0;
int n=-1;
int theta,phi;
const double PI = 3.1415926535897;
GLdouble DTOR = (PI/180);//degrees to radians
Vertex* sphere_vertices = new Vertex[no_vertices];
for (theta=-90;theta<=90-dtheta;theta+=dtheta) {
for (phi=0;phi<=360-dphi;phi+=dphi) {
//calculating Vertex 1
x = cos(theta*DTOR) * cos(phi*DTOR);
y = cos(theta*DTOR) * sin(phi*DTOR);
z = sin(theta*DTOR);
n+=1;
sphere_vertices[n].position[0] = x;
sphere_vertices[n].position[1] = y;
sphere_vertices[n].position[2] = z;
//calculating Vertex 2
x = cos((theta+dtheta)*DTOR) * cos(phi*DTOR);
y = cos((theta+dtheta)*DTOR) * sin(phi*DTOR);
z = sin((theta+dtheta)*DTOR);
n+=1;
sphere_vertices[n].position[0] = x;
sphere_vertices[n].position[1] = y;
sphere_vertices[n].position[2] = z;
//calculating Vertex 3
x = cos((theta+dtheta)*DTOR) * cos((phi+dphi)*DTOR);
y = cos((theta+dtheta)*DTOR) * sin((phi+dphi)*DTOR);
z = sin((theta+dtheta)*DTOR);
n+=1;
sphere_vertices[n].position[0] = x;
sphere_vertices[n].position[1] = y;
sphere_vertices[n].position[2] = z;
//adding Vertex_1 again to divide the Quad into 2 triangles so it can be later filled with triangles!!!
//adding Vertex 1 again!
x = cos(theta*DTOR) * cos(phi*DTOR);
y = cos(theta*DTOR) * sin(phi*DTOR);
z = sin(theta*DTOR);
n+=1;
sphere_vertices[n].position[0] = x;
sphere_vertices[n].position[1] = y;
sphere_vertices[n].position[2] = z;
if (theta > -90 && theta < 90) {
//calculating Vertex 4
x = cos(theta*DTOR) * cos((phi+dphi)*DTOR);
y = cos(theta*DTOR) * sin((phi+dphi)*DTOR);
z = sin(theta*DTOR);
n+=1;
sphere_vertices[n].position[0] = x;
sphere_vertices[n].position[1] = y;
sphere_vertices[n].position[2] = z;
}
}
}
//Setting the color
for(int i=0; i<no_vertices; i+=1)
{
sphere_vertices[i].color[0] = 1;
sphere_vertices[i].color[1] = 0;
sphere_vertices[i].color[2] = 0;
}
printf("%d >> \n", n);
return sphere_vertices;
}

編輯: 這是包括在我的test_1.cpp「主」方法所在。
#include "Sphere.h"
#include "Terrain.h"
using namespace std;
//Vertex Structure
struct Vertex {
GLdouble position[3];
GLfloat color[3];
GLfloat texture[2];
};
然後我創建一個球體這樣
sphere_vertices_final = planet_1->create_sphere(5,5,no_sphere_vertices);
我應該如何包含頂點在Sphere.h文件?
您錯過了'Vertex'聲明。也許你忘了'#include'它的頭部?如果聲明在同一個文件中,則需要在* Sphere的定義之前放置該聲明。另一個錯誤就是第一個雪球效應。 – 2012-01-10 11:43:55
它的標頭?頂點只是一個結構變量。我應該如何包括它? – 2012-01-10 11:46:13
如果它不在單獨的標題中,它需要超出「Sphere」的定義。 – 2012-01-10 11:47:45
