Arthus week6

week06

step1:下載glut32.dll windows.zip data.zip source.zip 並解壓縮到桌面

step2:去moodle下載week5
week5打開cbp檔

step3:去setting compiler 把c++11的勾勾取消

 

step4:執行

step5:打開transformation.c 搜尋light

step6 :打光程式碼
GLfloat pos[] = { 0.0, 0.0, -1.0, 0.0 };

glEnable(GL_DEPTH_TEST);

    glEnable(GL_LIGHTING);

    glEnable(GL_LIGHT0);

    glLightfv(GL_LIGHT0, GL_POSITION, pos);

step7:執行

step8:加入keyboard mouse

#include<stdio.h>
.
.
.
void keyboard (unsigned char key, int x, int y){

printf("now:%c (%d %d)\n",key,x,y);}

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

{

printf("now: %d %d (%d %d)\n",button,state,x,y);

}

在int main()

{

.

.

.

glutCreateWindow("week06");

glutDisplayFunc(display);

glutKeyboardFunc(Keyboard);

glutMouseFunc(mouse);

glutMainLoop();

}

step9:執行

keyboard讓東西轉 

step10:加 int rotateX=0,rotateY=0,rotateZ=0

在keyboard function中加入

    if(key=='1') rotateX++;

    if(key=='2') rotateY++;

    if(key=='3') rotateZ++;

glutPostRedisplay();///使得東西馬上更新

在display function中的drawmodol()前後加glPushMatrix()跟glPopMatrix()

並在前面加入

       glRotatef(rotateX,1,0,0);

        glRotatef(rotateY,0,1,0);

        glRotatef(rotateZ,0,0,1);

讓物體旋轉

step11:執行

MOUSE讓東西轉

step12:先加入int oldX=0,oldY=0;

在mouse function中加入

if(state==GLUT_DOWN)

    {

        oldX=x;

        oldY=y;

    }

並新增

void motion(int x, int y)

{

    rotateY+= -(x-oldX);

    rotateX+= -(y-oldY);

    oldX=x;

    oldY=y;

    glutPostRedisplay();

}

在main中新增glutMotionFunc(motion);

step13:執行
