GLUT程式(Transformation)

Transformation程式

開頭和之前一樣

->先到 這裡 下載win32, data, glut32.dll 
->win32, data解壓縮後將所有資料放入windows資料夾
-> 打開Transformation.exe

glTranslatef --- 控制位置

glRotatef --- 控制旋轉

glScalef --- 控制大小

->先畫出茶壺

->將原本的glutSolidTeapot改成glutWireTeapot
   茶壺會變成只有框架的茶壺
->加上glutWireCone畫出圓錐
->更改位置及旋轉點  讓圓錐點對準茶壺嘴
->加上滑鼠控制旋轉的程式碼 可讓圓椎透過滑鼠移動旋轉







程式碼
#include<GL/glut.h> float angle=0; void display() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glPushMatrix(); glTranslatef(0,0.5,0); glutWireTeapot(0.3); glPopMatrix(); glPushMatrix(); glTranslated(0.51,0.63,0); glRotatef(angle,0,0,1); glTranslatef(0.6,0,0); glRotatef(-90,0,1,0); glutWireCone(0.1,0.6,10,10); glPopMatrix(); glutSwapBuffers(); } void motion(int x,int y) { angle = x; display(); } int main(int argc, char**argv) { glutInit(&argc,argv); glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH); glutCreateWindow("week10 TRT"); glutDisplayFunc(display); glutMotionFunc(motion); glutMainLoop(); }
