                     利用1,2,3,4來控制骨架

電腦圖學筆記

主題:T-R-T旋轉

Transformation.exe 自轉vs.公轉

glTranslatef(....)                   glRotatef(.....) 

glRotatef(.....)                      glTranslatef(....) 

     

打上老師教的程式碼

#include <GL/glut.h>

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glTranslatef(0,0.5,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glPushMatrix();

    glPopMatrix();

    glPushMatrix();

        glTranslatef(0.50,0.625,0);

        glRotatef(angle,0,0,1);

        glTranslatef(0.6,0,0);

        glRotatef(-90,0,1,0);

        glutSolidCone(0.2,0.6,30,30);

    glPopMatrix();

    glutSwapBuffers();

}

void motion(int x,int y)

{

       angle=x;

       display();

}

int main(int argc, char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week10 TRT");

    glutDisplayFunc(display);

    glutMotionFunc(motion);

    glutMainLoop();

}

按著就可以旋轉了

      

week08貼圖

主題:貼圖Texture

1.把[data][window62]glut32.dll下載
2.把dataˋwindow32解壓縮
3.把data跟glut32.dll丟進window32裡面
4.開啟Texture

實作:OpenCV+OpenGL貼圖
google:OpenCV2.1找到第一個
裡面OpenCV-2.1.1-win32-vs2008.exe安裝
(1)要C:\OpenCV2.1目錄
(2)要選 Add PATH
(3)裝好後才能啟動codeblocks

下載https://www.transmissionzero.co.uk/software/freeglut-devel/

從CODEbLOCKS開啟glut專案把freeglut拉到桌面libfreeglut.a改成libglut32.a

然後按照圖片的步驟

最後

程式碼

#include <GL/glut.h>

#include <opencv/highgui.h>///貼圖需要

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    IplImage * img=cvLoadImage("earth.jpg");///貼圖需要

    cvShowImage("opencv Window", img);///貼圖需要

    cvWaitKey(0);///貼圖需要

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE |GLUT_DEPTH);

    glutCreateWindow("Week08");

    glutDisplayFunc(display);

    glutMainLoop();

}
