我正在尝试将数组形式的数据传递给 glutDisplayFunc 调用的函数。请让我知道这是否/如何可能或实现相同目标的简单替代方案。最终我会想要将很多值传递给绘图函数。谢谢!
#include "stdafx.h"
#include <ostream>
#include <iostream>
#include <Windows.h>
#include <ctime>
#include <vector>
using namespace std;
#include <glut.h>
void Draw(int passedArray[]) { // This is probably wrong but just to give you the idea
glClear(GL_COLOR_BUFFER_BIT);
glColor3f(1.0, 1.0, 1.0);
glBegin(GL_POINTS);
glVertex3f(passedArray[1], passedArray[2], 0.0); // A point is plotted based on passed data
glEnd();
glFlush();
}
void Initialize() {
glClearColor(0.0, 0.0, 0.0, 0.0); // Background color
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0.0, 1.0, 0.0, 1.0, -1.0, 1.0);
}
int main(int iArgc, char** cppArgv) {
cout << "Start Main" << endl;
glutInit(&iArgc, cppArgv);
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
glutInitWindowSize(250, 250); // Control window size
glutInitWindowPosition(200, 200);
glutCreateWindow("GA");
Initialize();
int passedArray[2] = {10, 20}; // create array
glutDisplayFunc(Draw(passedArray)); // This is not how you do this, just to try to convey what I want
glutMainLoop();
return 0;
}
