今日作業
打光的茶壺
程式碼：
#include <GL/glut.h>
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);
glutSolidTeapot(0.3);
glFlush();
}
int main(int argc,char **argv)
{
glutInit(&argc,argv);
glutCreateWindow("TRT 3D");
glutDisplayFunc(display);
glutMainLoop();
}
自動旋轉的茶壺
程式碼：
#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();
}
用滑鼠控制旋轉
程式碼：
#include <GL/glut.h>
float angle=0;
float 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();
}
兩個茶壺轉動(一個茶壺接著一個茶壺)
程式碼：
#include <GL/glut.h>
float angle=0;
float 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(0.43,0.13,0);///version 4:把樓下的整個在轉....往右掛在某個地方
glRotatef(angle,0,0,1);///version 3:rotating teapot on the handle
glTranslatef(0.45,-0.1,0);///version 2:teapot on the right
glutSolidTeapot(0.3);///version 1:create a teapot
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();
}
期末作業的東東
1.用圓錐製作身體
2.做手臂
程式碼：
#include <GL/glut.h>

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);
