Week07 老王

(老師這週剛好我們家家族旅遊所以請假借了同學的當作參考)
(1)主題：3D模型
(2)轉檔,OBJ格式(v,vt,vnf)
(3)期中考題(10行OpenGL Code)
(4)小考T-R-T
(5)回家作業：骨架階層矩陣

1.
(1)安裝、執行
TODO:下載jsyeh.org/3dcg10>>data.zip

(2)data.zip→桌面 / data / 3D模型
用 3D Exploration 開 3D模

下載jsyeh.org/3dcg10>>Source.zip
(1)glm.h
(2)glm.c重新命名glm.cpp
(3)transformation.c重新命名transfarmation,cpp
上述3個程式放入桌面week07_glm資料夾

freeglut>>bin放入data/模型
ib的改libfreeglut.a複製貼上檔名改libglut32.a

2.

打造 3D模型程式
(1)把上節課transfarmation.cpp內容刪除
(2)main.cpp放程式
#include "glm.h"///1.外掛
GLMmodel * pmodel=NULL;//2.指標
void display()

Week 04 潘家智的筆記

從老師的網站http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/
下載data、win32、glut32.dll 這三個檔案
將win32解壓縮然後把glut32.dll 放入window資料夾
執行Transfromation

安培右手定則
glRotatef( 角度, X軸, Y軸, Z軸);
X軸:正值>右手大拇指向右轉動向內
負值>右手大拇指向左轉動向外
Y軸:正值>右手大拇指向上轉動向內
負值>右手大拇指向下轉動向外
Z軸:正值>右手大拇指向內逆時針轉動
負值>右手大拇指向外順時針轉動

期中考考題

可以轉動的茶壺

Week 03 潘家智的筆記

(1)先從這個網址http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/
下載data.zip, windows.zip, glut32.dll 3個檔案

解壓縮windows.zip之後把glut32.dll複製進去
然後就可以執行shapes.exe

(2)再開啟codeblock glut專案並且畫出茶壺
增加滑鼠按下去就能顯示x,y座標的程式

增加程式碼讓座標以程式碼呈現執行後點出每個點

#include <GL/glut.h>
/*float teapotX=0,teapotY=0;*/
void display()
{
glClearColor(1,1,0,1);
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
/* glPushMatrix();
glTranslatef(teapotX,teapotY,0);
glutSolidTeapot(0.3);
glPopMatrix();*/
glutSwapBuffers();
}
#include <stdio.h>
void mouse(int button,int state,int x,int y)
{
if(state==GLUT_DOWN)printf("glVertex2f(%f, %f);\n",(x-150)/150.0,-(y-150)/150.0);

}
/*void motion(int x,int y)
{
teapotX=(x-150)/150.0;
teapotY=-(y-150)/150.0;
printf("%d %d\n",x,y);
