1.T-R-T小考
2.內插Interpolation
3.動作內插
TODO:T-R-T小考
程式碼:
glPushMatrix();
glTranslatef(x,y,z);
glRotatef(angle,x,y,z);
glTranslatef(x,y,z);
drawhand();
glPopMatrix();
TODO:用Excel作內插
公式:new*alpha+old*(1-alpha)
選取A & C 製作圖表
內插法
TODO:畫圖Excel插入x*y圖
新增:C:\Users\USER\Desktop\freeglut\include
新增:C:\Users\USER\Desktop\freeglut\lib
新增咒語:winmm/freeglut/gui32/gdi32/opengl32
1.motion()不要狂寫檔
2.keyboard()裡if(key=='s')
3.keyboard()的'r'讀一行,改裝't'先讀一行
4.加上timer,glutTimerFunc
程式碼:
#include <stdio.h>
#include <GL/glut.h>
FILE *fout=NULL, *fin=NULL;
float rot[10]={0}, rotold[10]={0}, rotnew[10]={0};
int rotID=1, oldX=0;

{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glutWireCube(0.3);
glPushMatrix();
glTranslatef(0,0.2,0);

glPopMatrix();

glutMainLoop();
}
't'->讀入位置
's'->存位置
'r'->播放
要先執行->然後拉位置->按S儲存->貼到Notepad++->再重新執行按T
