yun_電腦圖學筆記week11

 今天上課一開始，老師讓我們開啟以前開啟過的程式

接著下載freeglut並開啟專案

打開source壓縮檔裡面抓出glm.c、glm.h、transformation.c

複製到今天的專案資料夾內

將glm.c改成glm.cpp

將transformation.c裡面的程式碼用notepad++打開並複製程式碼貼到main.c的程式內取代原本的

在今天的專案右鍵點add files

加入glm.cpp的檔案

    此時會出現閃退的頁面，將data.zip裡面的data資料夾拉到freeglut/bin的資料夾裡面

可以在windows那裡更改顯示名稱，執行後視窗名字就變我設定的了!!!

將main原本的程式碼全部刪除，去notepad++複製有glm的程式碼過來

#include "glm.h" GLMmodel* pmodel = NULL; void drawmodel(void) { if (!pmodel) { pmodel = glmReadOBJ("data/porsche.obj"); if (!pmodel) exit(0); glmUnitize(pmodel); glmFacetNormals(pmodel); glmVertexNormals(pmodel, 90.0); } glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL); } void display() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); drawmodel(); glutSwapBuffers(); } int main(int argc, char **argv) { glutInit(&argc, argv); glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH); glutCreateWindow("08160093 week11"); glutDisplayFunc(display); glutMainLoop(); }

螢光筆是今天從glm內copy過來的程式碼，其餘的是以前學過的程式碼

執行後就會顯示出剛剛專案內的車子了!!

接著我們打個光，copy第八週的程式碼

#include "glm.h" GLMmodel* pmodel = NULL; void drawmodel(void) { if (!pmodel) { pmodel = glmReadOBJ("data/dolphins.obj"); if (!pmodel) exit(0); glmUnitize(pmodel); glmFacetNormals(pmodel); glmVertexNormals(pmodel, 90.0); } glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL); } void display() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glPushMatrix(); glRotatef(180,0,1,0); drawmodel(); glPopMatrix(); glutSwapBuffers(); } const GLfloat light_ambient[] = { 0.0f, 0.0f, 0.0f, 1.0f }; const GLfloat light_diffuse[] = { 1.0f, 1.0f, 1.0f, 1.0f }; const GLfloat light_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f }; const GLfloat light_position[] = { 2.0f, 5.0f, -5.0f, 0.0f }; const GLfloat mat_ambient[] = { 0.7f, 0.7f, 0.7f, 1.0f }; const GLfloat mat_diffuse[] = { 0.8f, 0.8f, 0.8f, 1.0f }; const GLfloat mat_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f }; const GLfloat high_shininess[] = { 100.0f }; int main(int argc, char **argv) { glutInit(&argc, argv); glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH); glutCreateWindow("08160093 week11"); glEnable(GL_DEPTH_TEST); glEnable(GL_LIGHT0); glEnable(GL_NORMALIZE); glEnable(GL_COLOR_MATERIAL); glEnable(GL_LIGHTING); glLightfv(GL_LIGHT0, GL_AMBIENT, light_ambient); glLightfv(GL_LIGHT0, GL_DIFFUSE, light_diffuse); glLightfv(GL_LIGHT0, GL_SPECULAR, light_specular); glLightfv(GL_LIGHT0, GL_POSITION, light_position); glMaterialfv(GL_FRONT, GL_AMBIENT, mat_ambient); glMaterialfv(GL_FRONT, GL_DIFFUSE, mat_diffuse); glMaterialfv(GL_FRONT, GL_SPECULAR, mat_specular); glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess); glutDisplayFunc(display); glutMainLoop(); }

這是老師給我們程式碼後出來的圖
