1. 總複習
開啟新project:week16_all/存在2023graphicsa/選擇Final_project內的freeglut/開始練習
step01.點線面色彩display(),glColor3f(r,g,b)
step02移動glTranslatef(),motion(),teapotX,teapotY
step03.旋轉glRotatef(angle,0,0,0),mouse(),oldX,oldY,angle=0放大、縮小glScalef()
step04.TRT的第一個T:可以移動到旋轉中心
step05.TRT完成
step06.將鋼彈模型讀進來glmDraw(gundam,GLM_MATERIAL);week10
step07.貼圖OpenCV
glmDraw(gundam,GLM_MATERIAL|GLM_TEXTURE);///加入貼圖功能,
main內myTexture("model/Diffuse.jpg");
gundam = glmReadOBJ("model/gundam.obj");
glEnable(GL_DEPTH_TEST);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);///3D功能
step08.將鋼彈模型拆分手腳，讀入頭模型，並讓他可以移動
main內head = glmReadOBJ("model/head.obj");
main內body = glmReadOBJ("model/body.obj");
step09.頭可以旋轉了
step10.11加入手臂、TRT
step12.13.14.快速加入其他部位，注意階層，左右邊只要改X的正負號
step15.用ID+keyboare()來選擇部位，擺好關節
step16.存檔keyboard內，按S存檔存進motion.txt裡
step17.按R讀motion.txt
step18.做動畫，加入計時器，按P讀檔案，播放
