2020電腦圖學B: week03想睡嘞

week3

上週教的!!!

程式碼:
#include <GL/glut.h>///為了 glutXXXX()還有glXXXXX
#include <stdio.h>///TODO: 為了printf()
void display()
{
glutSolidTeapot( 0.3 );
glutSwapBuffers();

}
void mouse(int button,int state,int x,int y)///TODO:
{///mouse函式:左0中1右2,下:0/上:1,x座標,y座標
printf("%d %d %d %d\n", button,state,x,y);
}
int main(int argc, char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week03");

glutDisplayFunc(display);///display的函式
glutMouseFunc(mouse);///TODO:mouse的函式
glutMainLoop();

}
*滑鼠點一下和放開的座標

程式碼:
#include <GL/glut.h>
#include <stdio.h>
float teapotX=0, teapotY=0; ///這裡是-1.0~ =1.0的座標
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glTranslatef(teapotX, teapotY, 0);
glutSolidTeapot( 0.3 );
glPopMatrix();
glutSwapBuffers();
}
void mouse (int button, int state, int x, int y)
{
printf("%f %f\n", (x-150)/150.0, (y-150)/150.0);///顯示座標位置
teapotX= (x-150)/150.0;
teapotY= -(y-150)/150.0;
/// 0....150...300
///減150 -150...0.....150
///除150 -1.......0.......1

}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week03");

glutDisplayFunc(display);
glutMouseFunc(mouse);
glutMainLoop();
}
*滑鼠點到哪裡，茶壺的位置就變到哪，原理是清除畫面，重新畫一個

程式碼:

float teapotX=0,teapotY=0;

void display()

{

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

// 程式碼產生的頂點

glEnd(); // 程式結束

glutSwapBuffers();

}

void mouse(int button,int state,int x,int y){

if(state==GLUT_DOWN) { // 按下去時產生座標，減一半，除一半.0，y 要加負號

printf("glVertex2f((%d-150)/150.0,-(%d-150)/150.0);\n",x,y); // 顯示

}
