Week10 T-R-T

(一)下載win32/data/glut32.dll

 http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/

打開Transformation複習移動、旋轉、縮放

自轉(自己為中心旋轉)如上

公轉(繞中心點轉)如上

------------------------------------------------------------

(二)下載freeglut 開啟codeblock

程式碼：

#include <GL/glut.h>

void display()

{

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc, char ** argv)

{

    glutInit( &argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("Week10 TRT");

    glutDisplayFunc(display);

    glutMainLoop();

}

------------------------------------------------------------


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(); glTranslatef(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(); }
