心臓を捧げよ! week05

step1-1

去老師的網站下載windows,data

step1-2

把汽車拉高,並且rotate讓車子向右移動,最後車子比原本位置靠右並以原先位置為中心開始旋轉

step2-1

去codeblocks開新專案week05-1_TRT_translate,並且打開上周教的程式碼,更改z軸,讓茶壺逆時針轉

新增一個綠色茶壺,然後讓原本的旋轉角度增加1.5倍,最後兩個茶壺一個原地旋轉,另一個以逆時鐘旋轉,並且會和第一個茶壺交會

#include<GL/glut.h>

float angle =0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glColor3f(1,0,0);

    glPushMatrix();

        glRotatef(angle,0,0,1);

        glTranslatef(0.8,0,0);

        glutSolidTeapot( 0.3 );

    glPopMatrix();

    glColor3f(0,1,0);

    glPushMatrix();

        glTranslatef(0.8,0,0);

        glRotatef(angle*1.5,0,0,1);

        glutSolidTeapot( 0.3 );

    glPopMatrix();

    glutSwapBuffers();

    angle++;

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week03");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glutMainLoop();

}

step2-2

打開proccecing,執行程式碼並畫出身體及手臂,改變手臂的中心點移動到身體中心,讓手臂繞著身體中心旋轉

step3-1

打開codeblocks,建立新專案,week05-2_TRT_robot

用week05-1的程式修改

做一個機械手臂

再複製程式碼並更改座標,變成左上角跟右上角都有手臂旋轉

#include<GL/glut.h>

float angle =0;

void mycube()

{

    glPushMatrix();

        glScalef(0.5,0.2,0.2);

        glutSolidCube(1);

    glPopMatrix();

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glColor3f(1,1,1);

    glutSolidCube(1);

        glPushMatrix();

        glTranslatef(0.5,0.5,0);

        glRotatef(angle,0,0,1);

        glTranslatef(0.25,0,0);

        glColor3f(0,1,0);

        mycube();

        glPopMatrix();

        glPushMatrix();

        glTranslatef(-0.5,0.5,0);

        glRotatef(angle,0,0,1);

        glTranslatef(0.25,0,0);

        glColor3f(0,1,0);

        mycube();

        glPopMatrix();

    glutSwapBuffers();

    angle++;

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week05");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glutMainLoop();

}
