1-1 考試練習

glPushMatrix();

glTranslatrf(x1,y1,z1);

glRotatef(angle,0,0,1);

glTranslatrf(x2,y2,z2);

glPopMarix();

開啟新專案Glut，檔名 week13_rect_TRT

套入10行程式，加上glRect() (四邊形的意思)

1-2 把TRT程式套用上去

1-3 讓紅色方框旋轉角度45度

#include <GL/glut.h>

float angle=45;

void display()

{

glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glColor3f(1,1,1);

glRectf(0.5,0.5,-0.5,-0.5);

glPushMatrix();

glRotatef(angle,0,0,1);

glTranslatef(-0.5,-0.4,0);

glColor3f(1,0,0);

glRectf(0.5,0.5,1.0,0.3);

glPopMatrix();

glutSwapBuffers();

}

int main(int argc, char**argv)

{///進階的main函式

glutInit( &argc, argv);///初始化

glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH);///兩倍交換避免畫面閃爍+3D深度

glutCreateWindow("week13_rect");///建視窗

glutIdleFunc(display);///電腦有空就畫

glutDisplayFunc( display );///畫圖函式

glutMainLoop();///主要迴圈

}

2-1

#include <GL/glut.h>

float angle=45,oldX=0;

void mouse(int button,int state,int x,int y){

oldX=x;

}

void motion(int x,int y){

angle+=(x-oldX);

oldX=x;

glutPostRedisplay();

}

void display()

{

glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glColor3f(1,1,1);

glRectf(0.5,0.5,-0.5,-0.5);

glTranslatef(0.5,0.5,0);

glRotatef(angle,0,0,1);

glTranslatef(-0.5,-0.4,0);
