*打光*讀入3D模型

1.把data放在window裡 執行Light Material

2.模擬考試

3.jsyeh.org/3dcg10下載source 把glm.c glm.h transformation.c

4.將glm.cpp加入(glm.c 改成glm.cpp)

5.

glPushMatrix();

        glTranslated(0,1.2,-6);

        glRotated(60,1,0,0);

        glRotated(a,0,0,1);

        glutSolidTeapot(1);

    glPopMatrix();

6.//畫模型

 glPushMatrix();

        glTranslated(0,1.2,-6);

        glRotated(60,1,0,0);

        glRotated(a,0,0,1);

      if (!pmodel) {///畫模型

        pmodel = glmReadOBJ("data/porsche.obj");

        if (!pmodel) exit(0);

        glmUnitize(pmodel);

        glmFacetNormals(pmodel);

        glmVertexNormals(pmodel, 90.0);

        }

        glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

    glPopMatrix();

7.//光源的設定

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 };

8.//Material 的設定

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 };
