電腦圖學 2015 3/26
(1).自製3D模型
(2).利用mouse旋轉
(3).回家作業
首先 先讓我們回顧 上周 及 上上周 的 函式功能
#include <GL/glut.h>
float a=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT); ///清畫面
glRotatef(a,0,1,0); //--------------------->在y軸 做旋轉
glutWireTorus(0.3,0.7,30,30);
glFlush();
a+=0.1; //------------------>角度 每次 改 0.1度
}
int main(int argc,char **argv)
{
glutInit(&argc,argv);
glutCreateWindow("02160270 冠羽");
glutDisplayFunc(display);
glutMainLoop();
}
緊接著 試著 改變 成 自己產生的圖形
其中
glPushMatrix();
.........程式碼
glPopMatrix(); ------------->為一個block
glBegin(GL_LINE_LOOP); ----------->一個block 可產生一個 連線
........
glEnd();
再改成 3維的 移動
三維向量(glVertex3f)-->三維向量就是指只有X軸跟Y軸跟Z軸
glVertex3f(X軸,Y軸,Z軸);
試著拉出會旋轉的長立方體
讓黑色邊線和它做疊合
做的特殊 測試
利用2D 疊圖 來做 偽3D的電圖
float a=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT); ///清畫面
glPushMatrix();
glRotatef(a,0,1,0.4);
///前面是面
glColor3f(0,1,1);///------------------------------------->青藍色三角立體柱

小葉老師 在 今天 最後 的 補充 能使 轉動變得更自然
不會亂跳畫面
