1.內插
2.動作內插
3.T-R-T小考
4.總複習
課堂作業1
用Excel作內插法
=A6*50+(1-A6)*10
new*alpha+old*(1-alpha)
插入圖表
課堂作業2:
讓茶壺移動
#include <stdio.h>
#include <GL/glut.h>
float pos=0, oldX=0, newX=0.1;
void display() ///顯示視窗
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glTranslatef(pos, 0, 0);
glutSolidTeapot(0.2); ///移動
glPopMatrix();
glutSwapBuffers();
}
void timer(int t)
{
float alpha=t/100.0;
pos = newX*alpha+oldX*(1-alpha);
printf("%d %f %f\n",t ,alpha, pos); ///印出移動位置glutTimerFunc(100,timer,t+1); ///每一秒往右移一步
glutPostRedisplay();
}
int main(int argc,char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("3D Interpolate");
glutDisplayFunc(display);
glutTimerFunc(100,timer,0);
glutMainLoop();
}
課堂做業3
把機器人叫出來的程式碼與今天所學的內插法下面是老師之前給的裡面的內容還需要改一下
#include <stdio.h>
#include <GL/glut.h>

if(fin==NULL) fin=fopen("motion.txt", "r");
for(int i=0;i<7;i++){

fscanf(fin, "%f", &rotNew[i]);
}
}
for(int i=0;i<7;i++){
