Week08 想不到吧

(1) 主題：打光

(2)期中模擬考

(3)T-R-T模擬考

(4)回家作業

(5)Recap (最少一個關節)


******  必須輸入此段
#include "glm.h"                     !!呼叫外掛
GLMmodel *pmodel = NULL;
static void display(void)

----------------------------------------------------------------------------------------

1.
http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/
 下載
[source][data][win32] glut32.dll

2.
開啟codeblocks   GLUT檔後 將下面3個檔案
(此檔案在source)
glm.cpp
glm.h
transformation.cpp
(其中2個要把.c改成.cpp)
然後放入

3.在main搜群display加
glm.cpp的
#include "glm.h"
trans....cpp的

GLMmodel * pmodel=NULL;
.......
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);




















#include "glm.h"
GLMmodel * pmodel=NULL;
static void display(void)
{
    const double t = glutGet(GLUT_ELAPSED_TIME) / 1000.0;
    const double a = t*90.0;

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glColor3d(1,0,0);

    glPushMatrix();
        glTranslated(-2.4,1.2,-6);
        glRotated(60,1,0,0);
        glRotated(a,0,0,1);
        glutSolidSphere(1,slices,stacks);
    glPopMatrix();

    glPushMatrix();
        glTranslated(0,1.2,-6);
        glRotated(60,1,0,0);
        glRotated(a,0,0,1);
    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);
        //glutSolidCone(1,1,slices,stacks);
    glPopMatrix();

4.因為新舊版本的差異記得去改Compiler 勾勾去掉 不然可能發生錯誤

5.畫簡main.cpp.程式碼(以下圖作為說明***)












































#include "glm.h"
GLMmodel * pmodel=NULL;
float angle=0;

void motion(int x,int y)
{
    angle = x;
    glutPostRedisplay();
}

static void display(void)
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();
        glRotatef(angle,0,1,0);
    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);
        ///glutSolidCone(1,1,slices,stacks);
    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 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("GLUT Shapes");
    glutDisplayFunc(display);
    glutMotionFunc(motion);

    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();

}

6.畫簡main.cpp.程式碼

        if (!pmodel) exit(0);
        glmUnitize(pmodel);
        glmFacetNormals(pmodel);
        glmVertexNormals(pmodel, 90.0);
        }

        glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);///身體
            ///glutSolidCone(1,1,slices,stacks);
        glPushMatrix();
            glTranslatef(0.4,0,0);
            glRotatef(angle,0,0,1);
            glTranslatef(0.4,0,0);
            glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);///右手臂
        glPopMatrix();

        glPushMatrix();
            glTranslatef(-0.4,0,0);
            glRotatef(-angle,0,0,1);
            glTranslatef(-0.4,0,0);
            glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);///左手臂
        glPopMatrix();

    glutSwapBuffers();
}
