- 期中考考題
- 畫茶壺關節
期中複習考題:
- glPushMartrix( );///備份矩陣
- glTranslatef(x,y,z);///移動
- glRotatef(angle,x,y,z);///旋轉
- glScalef(x,y,z);///縮放
- glBegin(GL_POLYGON );///開始
- glTexCoord2f(tx,ty);///貼圖
- glNormal3f(nx,ny,nz);///打光法向量
- glColor3f(r,g,b);///顏色
- glVertex3f(x,y,z);
- glEnd( );///結束
- glPopMartrix( );///還原矩陣
畫茶壺關節:
#include <GL/glut.h>
float mouseX=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT |GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotatef(mouseX,0,0,1);
glColor3f(1,0,0);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(0.5, 0.14,0);
glRotatef(mouseX,0,0,1);
glTranslatef(0.41,-0.05,0);
glColor3f(1,1,1);
glutSolidTeapot(0.3);
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
void motion(int x, int y)
{
mouseX = x;
glutPostRedisplay();
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_RGB|GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("TRT robot");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}
float mouseX=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT |GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotatef(mouseX,0,0,1);
glColor3f(1,0,0);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(0.5, 0.14,0);
glRotatef(mouseX,0,0,1);
glTranslatef(0.41,-0.05,0);
glColor3f(1,1,1);
glutSolidTeapot(0.3);
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
void motion(int x, int y)
{
mouseX = x;
glutPostRedisplay();
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_RGB|GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("TRT robot");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}
