关于c++转c#的问题，帮忙转换一下

Question

void _stdcall display (void){
// glClearColor(1.0,0.0,1.0,1.0); //设置背景颜色
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT); //设置背景颜色
glColor3f(1.0,1.0,0.0);//设置绘制图形所用颜色 //设置图形转换信息
glLoadIdentity();            //清空矩阵
glTranslatef(0.0,-1.0,-5.0); //把圆柱体向Y负方向平移1单位，向Z负方向平移5单位
glRotatef(15.0,1.0,0.0,0.0); //把圆柱体绕X轴旋转15°
//具体绘制图形
for(int i=0;i<N;i++)
drawSurface(&bottomVertex[i][0],&bottomVertex[i+1][0],&topVertex[i+1][0],&topVertex[i][0]);
//绘制最后一个缺口
drawSurface(&bottomVertex[N-1][0],&bottomVertex[0][0],&topVertex[0][0],&topVertex[N-1][0]);
glFlush();//结束图形绘制的顶点给定，并最终输出至显示器完成图形的显示
}
void drawSurface(double *v1,double *v2,double *v3,double *v4)
{

楼主给的代码不够全啊
Private void _stdcall display (){ 
// glClearColor(1.0,0.0,1.0,1.0); //设置背景颜色 
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT); //设置背景颜色 
glColor3f(1.0,1.0,0.0);//设置绘制图形所用颜色 //设置图形转换信息 
glLoadIdentity();            //清空矩阵 
glTranslatef(0.0,-1.0,-5.0); //把圆柱体向Y负方向平移1单位，向Z负方向平移5单位 
glRotatef(15.0,1.0,0.0,0.0); //把圆柱体绕X轴旋转15° 
//具体绘制图形 
for(int i=0;i <N;i++) 
drawSurface(bottomVertex[i][0],bottomVertex[i+1][0],topVertex[i+1][0],topVertex[i][0]); 
//绘制最后一个缺口 
drawSurface(bottomVertex[N-1][0],bottomVertex[0][0],topVertex[0][0],topVertex[N-1][0]); 
glFlush();//结束图形绘制的顶点给定，并最终输出至显示器完成图形的显示 
} 
Private void drawSurface(double v1,double v2,double v3,double v4) 
{ 
glBegin(GL_POLYGON);//绘制侧面 
glNormal3dv(v1); 
glVertex3dv(v1); glNormal3dv(v2); 
glVertex3dv(v2); glNormal3dv(v2); 
glVertex3dv(v3); glNormal3dv(v1); 
glVertex3dv(v4);

/* glBegin(GL_TRIANGLES);//绘制下底

Answer 2

不是这样的，你会opengl么？÷
glNormal3dv(v1); 
glVertex3dv(v1); 
这个里面是数组型的，
drawSurface(bottomVertex[N-1][0],bottomVertex[0][0],topVertex[0][0],topVertex[N-1][0]); 
这里它的指向地址类型的

 用C#开发opengl 

Answer 4

c# 中直接P/Invoke写好的东东
假设你的C++实在abc.dll里面public partial class NativeMethods
    {        /// Return Type: void
        [System.Runtime.InteropServices.DllImportAttribute("abc.dll")]
        public static extern void display();
        /// Return Type: void
        ///v1: double*
        ///v2: double*
        ///v3: double*
        ///v4: double*
        [System.Runtime.InteropServices.DllImportAttribute("abc.dll")]
        public static extern void drawSurface(ref double v1, ref double v2, ref double v3, ref double v4);    }
