選出五個自己覺得中意的作品
TIPS à(1)7-zip解壓縮
--------------------------------------------------------------------------------------------------
Class2
STEP 1
請先下載課堂教材(jsyeh/3dcg10/ ) data.zip , windows.zip , glut32.dll
à (1)理解上方右鍵可換Model
(2)下方綠字可drag
(3)下方右鍵可reset
<關於介面選項>
glTranslatef(x,y,z);
glRotatef(角度,x,y,z);
glScalef(x,y,z);
Class3
(1)程式設計實作
#include <GL/glut.h>
void display()
{
glClearColor(1,1,0,1);
glClear(GL_COLOR_BUFFER_BIT);
glTranslatef(0, -0.1, 0); >>>>>>>>這是未定位狀態,會隨著移動CMD發生位置Y軸往下移動0.1
glColor3f(1,0,0);
glutSolidTeapot(0.3);
glutSwapBuffers();
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("Hello");
glutDisplayFunc(display);
glutMainLoop();
}
(2)程式展示 : 用滑鼠在視窗內點擊,可移動茶壺

如何畫出圓形?
>>利用三角函數建立座標
#include <GL/glut.h>
#include <stdio.h>
#include <math.h>
float nowX=0, nowY=0;
void mouse(int button, int state, int x,int y)
{
nowX = (x-150)/150.0; nowY = -(y-150)/150.0;
printf("glTranslatef(%f,%f, 0);\n", nowX, nowY);
}
void display()
{
glClearColor(1,1,0,1);
glClear(GL_COLOR_BUFFER_BIT);
glPushMatrix();
glTranslatef(nowX,nowY,0);
glColor3f(1,0,0);
///glutSolidTeapot(0.3);
glBegin(GL_POLYGON);
for(float angle=0; angle<3.14159235358979*2; angle+=0.1){
glVertex2f(0.2*cos(angle), 0.2*sin(angle));
}
glEnd();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("Hello 3D");
glutDisplayFunc(display);
glutMouseFunc(mouse);
glutMainLoop();
}
EXTRA
可隨鼠標移動的黑圓與倒數警示

void mouse(int button, int state, int x, int y)
{
nowX = (x-150)/150.0; nowY=-(y-150)/150.0;
}
void display()
{
glClearColor(1,1,0,1);
glClear(GL_COLOR_BUFFER_BIT);
glPushMatrix();
glTranslatef(nowX, nowY, 0);
glColor3f(1,0,0);
glutSolidTeapot(0.3);
glPopMatrix()
glutSwapBuffers();
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("Hello");
glutDisplayFunc(display);
glutMouseFunc(mouse);
glutMainLoop();
}
glPushMatrixà備份Matrix
glPopMatrixà還原Matrix
