親手打造第1個GLUT程式

1.

glBegin(GL_TRIANGLES);

glColor3f(1.0f, 0.0f, 0.0f);   glVertex2f(0.0f,   1.0f);

glColor3f(0.0f, 1.0f, 0.0f);   glVertex2f(0.87f,  -0.5f);

glColor3f(0.0f, 0.0f, 1.0f);   glVertex2f(-0.87f, -0.5f);

glEnd();

2.

開第二個

3.

刪刪刪

#include <GL/glut.h>

static void display(void)

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSwapBuffers();

}

int main(int argc, char *argv[])

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("GLUT Shapes");

    glutDisplayFunc(display);    

    glutMainLoop();

}

4.

插進去

#include <GL/glut.h>

static void display(void)

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glBegin(GL_TRIANGLES);

    glColor3f(1.0f, 0.0f, 0.0f);   glVertex2f(0.0f,   1.0f);

    glColor3f(0.0f, 1.0f, 0.0f);   glVertex2f(0.87f,  -0.5f);

    glColor3f(0.0f, 0.0f, 1.0f);   glVertex2f(-0.87f, -0.5f);

    glEnd();

    glutSwapBuffers();

}

int main(int argc, char *argv[])

{

    glutInit(&argc, argv);///初始化

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);///顯示模式

    glutCreateWindow("GLUT Shapes");///開視窗

    glutDisplayFunc(display);///顯示函式

    glutMainLoop();///主迴圈，卡住他

}

ㄇ

5.

中間換一下

glBegin(GL_TRIANGLES);

glColor3f(1.0f, 0.0f, 0.0f);   glVertex2f(0.0f,   1.0f);

glColor3f(0.0f, 1.0f, 0.0f);   glVertex2f(0.87f,  -0.5f);

glColor3f(0.0f, 0.0f, 1.0f);   glVertex2f(-0.87f, -0.5f);

glEnd();

變

glutSolidTeapot(0.3);///實心茶壺

6.

int main(int argc, char *argv[])

由來
