为什么只显示二维 应该是三维的 帮帮忙啊

[crazyinit]

#include <iostream>
#include "GL/glut.h"
using namespace std;
void Tringles(void);

int main(int argc,char **argv){ 
	glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_SINGLE|GLUT_RGB);
    glutInitWindowSize(600,600);
    glutCreateWindow("三角形旋转");
    glClearColor(0.0,0.0,0.0,0.0);
	glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
//	glLoadIdentity();
    glutDisplayFunc(Tringles);
    glutMainLoop();
    return 0;
}

void Tringles(){
    glBegin(GL_TRIANGLES);
	   glColor3f(1.0,0.0,0.0);//前
	   glVertex3f(0.0,1.0,0.0);
	   glColor3f(0.0,1.0,0.0);
	   glVertex3f(-1.0,-1.0,1.0);
	   glColor3f(0.0,0.0,1.0);
	   glVertex3f(1.0,-1.0,1.0);

       glColor3f(1.0,0.0,0.0);//右
	   glVertex3i(0.0,1.0,0.0);
       glColor3f(0.0,1.0,0.0);
	   glVertex3i(1.0,-1.0,-1.0);
	   glColor3f(0.0,0.0,1.0);
	   glVertex3i(-1.0,-1.0,-1.0);

	   glColor3f(1.0,0.0,0.0);//左
	   glVertex3i(0.0,1.0,0.0);

为什么显示的是二维三角形 本来是想显示三维的三角形

[写不动代码的人]

坐标点对吗

[crazyinit]

glBegin(GL_TRIANGLES);
	   glColor3f(1.0,0.0,0.0);//前
	   glVertex3f(0.0,0.5,0.0);
	   glColor3f(0.0,1.0,0.0);
	   glVertex3f(-0.5,-0.5,0.5);
	   glColor3f(0.0,0.0,1.0);
	   glVertex3f(0.5,-0.5,0.5);

       glColor3f(1.0,0.0,0.0);//右
	   glVertex3i(0.0,0.5,0.0);
       glColor3f(0.0,1.0,0.0);
	   glVertex3i(0.5,-0.5,-0.5);
	   glColor3f(0.0,0.0,1.0);
	   glVertex3i(-0.5,-0.5,-0.5);

	   glColor3f(1.0,0.0,0.0);//左
	   glVertex3i(0.0,0.5,0.0);
	   glColor3f(0.0,1.0,0.0);
	   glVertex3i(-0.5,-0.5,-0.5);
	   glColor3f(0.0,0.0,1.0);
	   glVertex3i(-0.5,-0.5,0.5);

这样还是一个二维的

全部代码贴出来,人家叫你旋转,你旋转了吗,不旋转的话3维看起来就是二维的

第一个三角形没错，第二个和第三个函数用错了，应该用glVertex3f，用glVertex3i的话回把0.5强制转换为0，实际上会把三角形画成1个点

是啊，要转转看，还要确保顶点顺序是正确的，如果打开了剔除。
