week12_簡上棋

(1)作業回顧
(2)作業需求(小遊戲)
(3)3D modle模型glm.c
(4)Maya轉OBJ檔
(5)介紹助教影片資源

把要用到的檔案複製到專案底下
然後把glm.c 改為 glm.cpp

#include "glm.h"

GLMmodel* pmodel = NULL;

int main()
{
pmodel = glmReadOBJ("data/porsche.obj");
glmUnitize(pmodel);
glmFacetNormals(pmodel);
glmVertexNormals(pmodel, 90.0);

}

把OBJ黨放在 freeglut bin資料裡面

#include "glm.h"

GLMmodel* pmodel = NULL;

void display()
{
glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);
glFlush();
}

int main(int argc, char**argv)
{ glutInit(&argc, argv);
glutCreateWindow("3D");

pmodel = glmReadOBJ("porsche.obj");
glmUnitize(pmodel);
glmFacetNormals(pmodel);
glmVertexNormals(pmodel, 90.0);

glutDisplayFunc(display);

glutMainLoop();
}

#include "glm.h"

GLMmodel* pmodel = NULL;

void display()

{

GLfloat pos[] = { 0.0, 0.0, -1.0, 0.0 };

glLightfv(GL_LIGHT0, GL_POSITION, pos);

glEnable(GL_LIGHTING);

glEnable(GL_LIGHT0);

glEnable(GL_DEPTH_TEST);

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

glFlush();

}

int main(int argc, char**argv)

{ glutInit(&argc, argv);

glutCreateWindow("3D");

pmodel = glmReadOBJ("porsche.obj");

glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

week10_簡上棋

下載
http://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.1/

安裝時設定

開啟 Code Block 新專案 Console application

設定各種設定~~~

把需要的圖檔裝到專案下

把OpenCV2.1 裡的cv210.dll cxcore210.dll highgui210.dll

複製到專案下

打上各種程式

#include <opencv/highgui.h>

int main()

{

IplImage * img = cvLoadImage("image.jpg");

cvShowImage("2D",img);

cvWaitKey(0);

}

再加上 3D 的設定

打上3D程式

#include <opencv/highgui.h>

#include <GL/glut.h>

float angle=0;

void display()

{

glClear(GL_COLOR_BUFFER_BIT);

glPushMatrix();

glRotatef(angle,0,1,0);

glutSolidTeapot(0.3);

glPopMatrix();

glFlush();

angle+=0.1;

main(int argc,char ** argv)

{

IplImage * img = cvLoadImage("image.jpg");

cvShowImage("2D",img);

//cvWaitKey(0);

glutInit(&argc,argv);

glutCreateWindow("3D");

glutDisplayFunc(display);

glutIdleFunc(display);

glutMainLoop();

}

加上專業程式

#include <GL/glut.h> ///我們要使用 GLUT 3D 外掛
#include <opencv/highgui.h> ///要使用 OpenCV的高級High圖形介面GUI
#include <opencv/cv.h> ///為了 cvCvtColor()而加上 cv.h
float angle=0; ///為了自動轉的角度angle
void display()
{
glEnable(GL_DEPTH_TEST); ///有深度(depth)測試的功能, 才會有正確的景深/前後關係
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); ///清畫面
glPushMatrix(); ///備份matrix
glRotatef(angle, 0,1,0); ///為了自動轉的角度angle
glutSolidTeapot(0.3); ///茶壼
glPopMatrix(); ///還原matrix
glFlush(); ///把馬桶沖出去
angle+=0.1; ///為了自動轉的角度angle
}
void init()
{ IplImage * img = cvLoadImage("image.jpg"); ///讀圖檔
cvCvtColor(img, img, CV_BGR2RGB); /// ConVerT Color 把圖 BGR 變成 RGB
glEnable(GL_TEXTURE_2D); ///開啟 2D貼圖功能
GLuint id; /// unsigned int 整數, 要存你的貼圖ID
glGenTextures(1, & id ); /// Generate 產生貼圖ID
glBindTexture(GL_TEXTURE_2D, id); /// Bind 綁貼圖ID
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); ///參數設定貼圖 S軸如果超過了, 就REPEAT
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); ///參數設定貼圖 T軸如果超過了, 就REPEAT

glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); ///參數設定貼圖縮小時就用最近點內插
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img->width, img->height, 0, GL_RGB, GL_UNSIGNED_BYTE, img->imageData);
} /// 很長的一行, 把 image的圖, 全部設成貼圖的內容
int main(int argc, char**argv) ///小心,要有 argc, argv哦
{
glutInit(&argc, argv); ///小心有個 & 哦
glutCreateWindow("3D"); ///建個3D視窗

glutDisplayFunc(display); ///畫圖函式
glutIdleFunc(display); ///閒閒沒事幹, 就重畫

init(); ///在 MainLoop前, 去做 initial 初始設定 (2D OpenCV, 3D OpenGL Texture)

glutMainLoop(); ///主要迴圈卡住, 才不會突然程式就結束了
}
