week11熊貓大人到此一遊

 1.

moodle 下載範例 source.zip ，windows.zip ，data.zip

windows.zip解壓縮➡️下載裡面的transformation.exe

data.zip解壓縮➡️把data丟到windows

source.zip解壓縮➡️下載glm.c ,glm.g,transformation.c

2.

freegult設定好，建好專案

把source裡的檔案加進去新建好的資料夾，放在同一個目錄

glm.c改檔名成glm.cpp

glm.h放同目錄

transformation.c的內容放到main.cpp(用notepad++開啟 ,複製貼到main)

把glm.cpp放進去專案➡️左邊project，add專案，glm.cpp加入

把data檔案拉進freegult/bin目錄

程式碼:

#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("week11 我的3d模型");

glutDisplayFunc(display);

glutMainLoop();

}

加上打光後的程式碼

#include "glm.h"

GLMmodel * pmodel =NULL;

void drawmodel(void)

{

    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);

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

    glRotatef(180,0,1,0);///轉動180度

    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 };///負號記得加

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("week11 我的3d模型");

    glEnable(GL_DEPTH_TEST);///深度記得加

    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();

}

6. 整合貼圖 用 Week08的貼圖函式

6.1. myTexture()

6.2. 在 main() 的 glutMainLoop()之前 myTexture("Diffuse.jpg")

6.3. 安裝 OpenCV 2.1, 小心 PATH

6.4. CodeBlocks 的 Setting-Compiler要設好多東西

     C:\OpenCV2.1\include

     C:\OpenCV2.1\lib

     cv210 cxcore210 highgui210

     再重開 CodeBlocks即可!!!!
