(5)作業問題
1.以把手為中心轉的茶壺 並加入打光
#include <GL/glut.h>
float angle=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();
}
int main(int argc,char **argv)
{
glutInit(&argc,argv);
glutCreateWindow("TRT 3D");
glutDisplayFunc(display);
glutTimerFunc(20,timer,0);
glutMainLoop();
}
2.用滑鼠拖曳旋轉的茶壺
#include <GL/glut.h>
float angle=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();
}
int oldX,oldY;
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();
}
3.做出關節效果的手臂
#include <GL/glut.h>
float angle=0;
void drawArm()
{
glPushMatrix();
//glTranslatef(0,-0.5,0);
glRotatef(-90,1,0,0);
glScalef(0.5,0.25,0.25);
glutSolidCube(1);
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(0.25,0,0);
glRotatef(angle,0,0,1);
glTranslatef(0.25,0,0);
drawArm();
glPushMatrix();
glTranslatef(0.25,0,0);
glRotatef(angle,0,0,1);
glTranslatef(0.25,0,0);
drawArm();
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(-0.25,0,0);
glRotatef(-angle,0,0,1);
glTranslatef(-0.25,0,0);
drawArm();
glPushMatrix();
glTranslatef(-0.25,0,0);
glRotatef(-angle,0,0,1);
glTranslatef(-0.25,0,0);
drawArm();
glPopMatrix();
glPopMatrix();
// glTranslatef(0.5,0,0);
glFlush();
}
int oldX,oldY;
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();
}
