下載freeglut 以及老師給的程式碼在120.125.89.81
#include <GL/glut.h>
float angle=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(255,255,255);///白色
glutSolidTeapot( 0.3 );///身體
///右邊的手臂
glPushMatrix();
glTranslatef(0.2, 0,0 );///(3)往右移動, 掛在身體的右肩
glRotatef(angle, 0,0,1);///(2)旋轉
glTranslatef(0.28, 0,0);///(1)往右推,把茶壼的柄,放到中心,變 轉動軸
glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPopMatrix();
glutSwapBuffers();
angle++;
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week11 TRT");
glutIdleFunc(display);///Now!!!!
glutDisplayFunc(display);
glutMainLoop();
}
--------------------------------------------------------
第二個 跟手臂一樣有關節會動
#include <GL/glut.h>
float angle=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(255,255,255);///白色
glutSolidTeapot( 0.3 );///身體
///右邊的手臂
glPushMatrix();
glTranslatef(0.2, 0,0 );///(3)往右移動, 掛在身體的右肩
glRotatef(angle, 0,0,1);///(2)旋轉
glTranslatef(0.28, 0,0);///(1)往右推,把茶壼的柄,放到中心,變 轉動軸
glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPushMatrix();
glTranslatef(0.2, 0,0 );
glRotatef(angle, 0,0,1);
glTranslatef(0.28, 0,0);
glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(-0.2, 0,0 );///(3)往右移動, 掛在身體的右肩
glRotatef(angle, 0,0,1);///(2)旋轉
glTranslatef(-0.28, 0,0);///(1)往右推,把茶壼的柄,放到中心,變 轉動軸
glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPushMatrix();
glTranslatef(-0.2, 0,0 );
glRotatef(angle, 0,0,1);
glTranslatef(-0.28, 0,0);
glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
angle++;
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week11 06160565");
glutIdleFunc(display);///Now!!!!
glutDisplayFunc(display);
glutMainLoop();
}
--------------------------------------------------------------
第三個 用滑鼠移動關節
#include <GL/glut.h>
float angle=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(255,255,255);///白色
glutSolidTeapot( 0.3 );///身體
///右邊的手臂
glPushMatrix();
glTranslatef(0.2, 0,0 );///(3)往右移動, 掛在身體的右肩
glRotatef(angle, 0,0,1);///(2)旋轉
glTranslatef(0.28, 0,0);///(1)往右推,把茶壼的柄,放到中心,變 轉動軸
glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPushMatrix();
glTranslatef(0.2, 0,0 );
glRotatef(angle, 0,0,1);
glTranslatef(0.28, 0,0);
glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(-0.2, 0,0 );///(3)往右移動, 掛在身體的右肩
glRotatef(angle, 0,0,1);///(2)旋轉
glTranslatef(-0.28, 0,0);///(1)往右推,把茶壼的柄,放到中心,變 轉動軸
glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPushMatrix();
glTranslatef(-0.2, 0,0 );
glRotatef(angle, 0,0,1);
glTranslatef(-0.28, 0,0);
glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
///angle++;
}
void motion(int x,int y)
{
angle=x;
display();
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week11 06160565");
glutIdleFunc(display);///Now!!!!
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}
第三個 用滑鼠移動關節
#include <GL/glut.h>
float angle=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(255,255,255);///白色
glutSolidTeapot( 0.3 );///身體
///右邊的手臂
glPushMatrix();
glTranslatef(0.2, 0,0 );///(3)往右移動, 掛在身體的右肩

glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPopMatrix();
glPopMatrix();

glutSolidTeapot( 0.2 );///手臂
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
///angle++;
}
void motion(int x,int y)
{
angle=x;
display();
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week11 06160565");
glutIdleFunc(display);///Now!!!!
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}
-----------------------------------
第四個 透過按鍵1 2 3 4 設定動哪個關節
#include <GL/glut.h>
float angle1,angle2,angle3,angle4;
int joinID=1;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(255,255,255);///白色
glutSolidTeapot( 0.3 );///身體
///右邊的手臂
glPushMatrix();
glTranslatef(0.2, 0,0 );///(3)往右移動, 掛在身體的右肩
glRotatef(angle1, 0,0,1);///(2)旋轉
glTranslatef(0.28, 0,0);///(1)往右推,把茶壼的柄,放到中心,變 轉動軸
glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPushMatrix();
glTranslatef(0.2, 0,0 );
glRotatef(angle2, 0,0,1);
glTranslatef(0.28, 0,0);
glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(-0.2, 0,0 );///(3)往右移動, 掛在身體的右肩
glRotatef(angle3, 0,0,1);///(2)旋轉
glTranslatef(-0.28, 0,0);///(1)往右推,把茶壼的柄,放到中心,變 轉動軸
glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPushMatrix();
glTranslatef(-0.2, 0,0 );
glRotatef(angle4, 0,0,1);
glTranslatef(-0.28, 0,0);
glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
///angle++;
}
void motion(int x,int y)
{
if(joinID==1) angle1=x;
if(joinID==2) angle2=x;
if(joinID==3) angle3=x;
if(joinID==4) angle4=x;
display();
}
void keyboard(unsigned char key,int x,int y)
{
if(key=='1') joinID=1;
if(key=='2') joinID=2;
if(key=='3') joinID=3;
if(key=='4') joinID=4;
display();
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week11 06160565");
glutIdleFunc(display);///Now!!!!
glutDisplayFunc(display);
glutMotionFunc(motion);
glutKeyboardFunc(keyboard);
glutMainLoop();
}
而這次特別加上glutKeyboardFunc(keyboard);
讓程式可以偵測到我們按了數字鍵幾號
並設定出 按1 2 3 4各動哪些關節
------------------------------------------
第五個 因為如果我們有20個關節要動 打20個if實在太纍贅了 所以使用矩陣
就不需要打這麼多程式碼 看起來也更整潔乾淨了
#include <GL/glut.h>
float angle[20];
int joinID=1;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(255,255,255);///白色
glutSolidTeapot( 0.3 );///身體
///右邊的手臂
glPushMatrix();
glTranslatef(0.2, 0,0 );///(3)往右移動, 掛在身體的右肩
glRotatef(angle[1], 0,0,1);///(2)旋轉
glTranslatef(0.28, 0,0);///(1)往右推,把茶壼的柄,放到中心,變 轉動軸
glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPushMatrix();
glTranslatef(0.2, 0,0 );
glRotatef(angle[2], 0,0,1);
glTranslatef(0.28, 0,0);
glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(-0.2, 0,0 );///(3)往右移動, 掛在身體的右肩
glRotatef(angle[3], 0,0,1);///(2)旋轉
glTranslatef(-0.28, 0,0);///(1)往右推,把茶壼的柄,放到中心,變 轉動軸
glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPushMatrix();
glTranslatef(-0.2, 0,0 );
glRotatef(angle[4], 0,0,1);
glTranslatef(-0.28, 0,0);
glColor3f(255,0,0);///紅色
glutSolidTeapot( 0.2 );///手臂
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
///angle++;
}
void motion(int x,int y)
{
angle[joinID]=x;
///if(joinID==1) angle1=x;
///if(joinID==2) angle2=x;
///if(joinID==3) angle3=x;
///if(joinID==4) angle4=x;
display();
}
void keyboard(unsigned char key,int x,int y)
{
if(key=='1') joinID=1;
if(key=='2') joinID=2;
if(key=='3') joinID=3;
if(key=='4') joinID=4;
display();
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week11 06160565");
glutIdleFunc(display);///Now!!!!
glutDisplayFunc(display);
glutMotionFunc(motion);
glutKeyboardFunc(keyboard);
glutMainLoop();
}
因此上述有些程式碼便可以刪除 就不需要那麼佔版面了
