耀鑫的筆記 Week06

1.先把需要的東西都先下載下來source、data、win32、glut32.dll還有Download freeglut 3.0.0 for MinGW，然後依照前幾周的步驟把檔案準備好。

2.將程式碼複製貼上
#include <GL/glut.h> void display() { glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT); glutSolidTeapot(0.3); 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_DOUBLE|GLUT_DEPTH); glutCreateWindow("week06"); glutDisplayFunc(display); glClearColor(1,1,1,1); glEnable(GL_CULL_FACE); glCullFace(GL_BACK); glEnable(GL_DEPTH_TEST); glDepthFunc(GL_LESS); 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); glutMainLoop(); }
※如何貼上彩色程式碼※
①將所有程式碼全選貼到notepad++
②存成.cpp檔
③外掛 ⇒ NppexPort ⇒ Export to HTML ⇒ 用google開啟
④複製貼上

3.把source.zip打開把glm.c、glm.h、lightmaterial.c解壓縮出來，然後先把lightmaterial.c用note++打開，並把以下程式碼複製到codeblocks:

#include "glm.h"

GLMmodel* pmodel = NULL;

    if (!pmodel)
    {
pmodel = glmReadOBJ("data/dolphins.obj");
if (!pmodel) exit(0);
glmUnitize(pmodel);
glmFacetNormals(pmodel);
glmVertexNormals(pmodel, 90.0);
    }
    glmDraw(pmodel, GLM_SMOOTH);

4.開啟MAYA把檔案用obj檔匯出

先選取要匯出的物件後，點選Eport Selection將物件匯出成obj檔並丟到freeglut/bin裡面之後再改程式碼即可顯現3D模型。

最後的程式碼
#include <GL/glut.h> #include "glm.h" float x=0,y=0;///現在重點在滑鼠 GLMmodel* pmodel = NULL; void display() { glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT); glPushMatrix(); glRotatef(y,1,0,0); glRotatef(x,0,1,0); if (!pmodel) { pmodel = glmReadOBJ("ice.obj"); if (!pmodel) exit(0); glmUnitize(pmodel); glmFacetNormals(pmodel); glmVertexNormals(pmodel, 90.0); } glmDraw(pmodel, GLM_SMOOTH|GLM_MATERIAL); glPopMatrix(); glutSwapBuffers(); } void motion(int nowx,int nowy) { x=nowx;y=nowy; display(); } 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_DOUBLE|GLUT_DEPTH); glutCreateWindow("week06"); glutDisplayFunc(display); glClearColor(1,1,1,1); ///glEnable(GL_CULL_FACE); glCullFace(GL_BACK); glEnable(GL_DEPTH_TEST); glDepthFunc(GL_LESS); glutMotionFunc(motion); 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); glutMainLoop(); }
