week06-3D模型


(1)複習上週:打光
http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/下載win32、data、glut32.dll、source
依然解壓縮所需資料夾,win32, data放入windows資料夾,完成上禮拜的茶壺程式




















解壓縮source.zip
Notepad++打開lightmaterial.c
複製所需程式碼貼到茶壺程式如下





glm.h以及glm.c加入程式碼資料夾
並將glm.c的副檔名改為glm.cpp




在code blocks 資料夾點右鍵 Add files
加入glm.cpp




最後將data資料夾放入freeglut資料夾的bin資料夾裡面程式即可成功執行

修改後



完整程式碼:
#include <GL/glut.h> #include "glm.h" GLMmodel* pmodel = NULL; 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 }; float angle=0; void display() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glPushMatrix(); glRotatef(angle++,0,1,0); glScalef(0.5,0.5,0.5); if (!pmodel) { pmodel = glmReadOBJ("data/AL.obj"); if (!pmodel) exit(0); glmUnitize(pmodel); glmFacetNormals(pmodel); glmVertexNormals(pmodel, 90.0); } glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL); glPopMatrix(); ///glutSolidTeapot(0.3); glutSwapBuffers(); } int main(int argc,char ** argv) { glutInit(&argc,argv); glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH); glutCreateWindow("Week06"); glutDisplayFunc(display); glutIdleFunc(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(); }
