1)期末作品
2)會跳舞的機械人
3)T-R-T對關節轉
4)小考:T-R-T觀念
5)作業問題
先載好freeglut,所以開codeblocks新增freeglut專案.
打三個旋轉的版本
ver1:打光茶壺
ver2:()往右移
ver3:( )整盤旋轉
茶壺就自己在轉囉.
可以再加上mouse()就可以用滑鼠控制茶壺在轉~~
#include <GL/glut.h>
float angle=0,oldX=0,oldY=0;
void display()
{
{
GLfloat pos[]={0,0,-1,0};
glLightfv(GL_LIGHT0,GL_POSITION,pos);
glEnable(GL_LIGHT0);
glEnable(GL_LIGHTING);
}
glEnable(GL_DEPTH_TEST);
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotatef(angle,0,0,1);
glTranslatef(0.5,0,0);
glutSolidTeapot(0.3);
glPopMatrix();
glFlush();
}
void timer(int t)
{
glutTimerFunc(20,timer,0);
angle++;
glutPostRedisplay();
}
void mouse(int button,int state,int x,int y)
{
if(state==GLUT_DOWN){ oldX=x; oldY=y; }
}
void motion(int x, int y)
{
angle+=(x-oldX);
oldX=x;
}
int main(int argc,char **argv)
{
glutInit(&argc,argv);
glutCreateWindow("TRT 3D");
glutDisplayFunc(display);
glutTimerFunc(20,timer,0);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutMainLoop();
}
來複習一下:
第一步:先弄一個茶壺
第三步:
把第一個扣在第二個茶壺上面.
#include <GL/glut.h>
float angle=0,oldX=0,oldY=0;
void display()
{
{
GLfloat pos[]={0,0,-1,0};
glLightfv(GL_LIGHT0,GL_POSITION,pos);
glEnable(GL_LIGHT0);
glEnable(GL_LIGHTING);
}
glEnable(GL_DEPTH_TEST);
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glTranslatef(0.41,0.15,0); //第三
glRotatef(angle,0,0,1); //第二
glTranslatef(0.5,0,0); // 第一
glutSolidTeapot(0.3);
glPopMatrix();
glutSolidTeapot(0.3);
glFlush();
}
void timer(int t)
{
glutTimerFunc(20,timer,0);
//angle++;
glutPostRedisplay();
}
void mouse(int button,int state,int x,int y)
{
if(state==GLUT_DOWN){ oldX=x; oldY=y; }
}
void motion(int x, int y)
{
angle+=(x-oldX);
oldX=x;
}
int main(int argc,char **argv)
{
glutInit(&argc,argv);
glutCreateWindow("TRT 3D");
glutDisplayFunc(display);
glutTimerFunc(20,timer,0);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutMainLoop();
}
知道觀念之後就可以做一些圖案出來試試看.
#include <GL/glut.h>
float angle=0,oldX=0,oldY=0;
void drawArm()
{
glPushMatrix();
glScalef(0.5,0.25,0.25);
glutSolidCube(1);
glPopMatrix();
}
void drawBody()
{
glPushMatrix();
glTranslatef(0,-0.5,0);
glRotatef(-90,1,0,0);
glutSolidCone(0.3,0.8,30,30);
glPopMatrix();
}
void display()
{
{
GLfloat pos[]={0,0,-1,0};
glLightfv(GL_LIGHT0,GL_POSITION,pos);
glEnable(GL_LIGHT0);
glEnable(GL_LIGHTING);
}
glEnable(GL_DEPTH_TEST);
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glTranslatef(0.15,0,0);
glRotatef(angle,0,0,1);
glTranslatef(0.25,0,0);
//glutSolidTeapot(0.3);
drawArm();
glPushMatrix();
glTranslatef(0.25,0,0);
glRotatef(angle,0,0,1);
glTranslatef(0.25,0,0);
drawArm();
glPopMatrix();
glPopMatrix();
//以上是右手,以下是左手(程式碼是一樣,只有正負號不一樣)這樣就可以做出兩隻手啦.
glPushMatrix();
glTranslatef(-0.15,0,0);
glRotatef(angle,0,0,-1);
glTranslatef(-0.25,0,0);
//glutSolidTeapot(0.3);
drawArm();
glPushMatrix();
glTranslatef(-0.25,0,0);
glRotatef(angle,0,0,-1);
glTranslatef(-0.25,0,0);
drawArm();
glPopMatrix();
glPopMatrix();
drawBody();
glFlush();
}
void timer(int t)
{
glutTimerFunc(20,timer,0);
//angle++;
glutPostRedisplay();
}
void mouse(int button,int state,int x,int y)
{
if(state==GLUT_DOWN){ oldX=x; oldY=y; }
}
void motion(int x, int y)
{
angle+=(x-oldX);
oldX=x;
}
int main(int argc,char **argv)
{
glutInit(&argc,argv);
glutCreateWindow("TRT 3D");
glutDisplayFunc(display);
glutTimerFunc(20,timer,0);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutMainLoop();
}
