Week11 王婉懿的上課筆記

作業一 : 載入模型

         步驟 一 : 下載軟體"3D Exploration v1.81"。
             連結 : http://www.freespacemods.net/e107_plugins/download/download.php?view.129

 

         步驟 二 : 軟體"3D Exploration v1.81"解壓縮。

 

           步驟三 : 打開新網址「jsyeh.org/3dcg10」，將data檔案下載在桌面上。
           連結 : http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/

 

           

 

          步驟四 : 將剛下載的window解壓縮。

 

         步驟五 : 打開"3D Exploration "，從剛剛下載的data，載入足球模型。

 

          步驟六 : 另存足球模型為 cpp 檔。

 

           步驟七 : 另存設為"sample APP"。

 

          步驟八 : 建Open GL專案。

          步驟九 : 專案類型選擇OpenGL Project

          步驟十 : 出現畫面上的視窗，點選 next

          步驟十一 : 專案名稱打上「學號_hw2_opengl」，儲存目的選擇不用更改，點選 Next

         步驟十二 : 點選 Finish

         步驟十三 : 開始執行程式

 

          步驟十四 : 足球模型CPP檔移入專案。

 

           步驟十五 : 執行足球模型。

 

 

作業二 : 組合機器人

         步驟一 : 分別匯入三隻海豚。

 

 

         步驟二 : 三隻海豚移入myGLMsample資料夾中的data。

 

         步驟三 : 從專案打開myGLMsample。

 

          步驟四 : 下載" freeglut "。

 

 

           步驟五 : 打開freeglut拖曳檔案到桌面，千萬不要直接解壓縮 !

 

           步驟六 : 改程式碼，讓三隻海豚合體。
                程式碼 :
                #include <string.h>
                #include <stdlib.h>
                #include <GL/glut.h>
                #include "glm.h"
                GLMmodel* pmodel = NULL;
                GLMmodel* pmodel2 = NULL;
                GLMmodel* pmodel3 = NULL;
                float angle=0;
                void display()
                {              
                    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
                    glPushMatrix();
                        angle++;
                        glRotatef(angle, 0,1,0);
                        if (!pmodel) {
                        pmodel = glmReadOBJ("data/dolphins1.obj");
                        if (!pmodel) exit(0);
                        glmUnitize(pmodel);
                        glmFacetNormals(pmodel);
                        glmVertexNormals(pmodel, 90.0);
                        }
                        glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);
                        if (!pmodel2) {

                        }
                        glmDraw(pmodel2, GLM_SMOOTH | GLM_MATERIAL);
                        if (!pmodel3) {
                        pmodel3 = glmReadOBJ("data/dolphins3.obj");
                        if (!pmodel3) exit(0);
                        glmUnitize(pmodel3);
                        glmFacetNormals(pmodel3);
                        glmVertexNormals(pmodel3, 90.0);
                        }
                        glmDraw(pmodel3, GLM_SMOOTH | GLM_MATERIAL);
                    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_DOUBLE | GLUT_DEPTH | GLUT_RGB);
                    glutCreateWindow("Yes, 3D Model Here");
                    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);
