期中考:OpenGL必備十函式
複習:移動 旋轉 縮放
觀察自轉和公轉差別
主題:T-R-T旋轉(改變旋轉軸)ˇ
#include <GL/glut.h>
float angle=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT| GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glTranslatef(0,0.5,0);
glutSolidTeapot( 0.3 );
glPopMatrix();
glPushMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(0.5,0.625,0);
glRotatef(angle,0,0,1);
glTranslatef(0.6,0,0);
