我可以创建一个PopUp菜单来使用SDL在OpenGL中更改或修改我的灯光属性吗?
我正在尝试使用glutCreateMenu();
:
void mydisplay()
{
//glClear(GL_COLOR_BUFFER_BIT);
GLfloat tp_ambient[] = { 0.05,0.05,0.05,1 };
GLfloat tp_diffuse[] = { 0.7,0.3,1,1 };
GLfloat tp_specular[] = { 0.6,0.6,0.6,1 };
glMaterialfv(GL_FRONT_AND_BACK, GL_AMBIENT, tp_ambient);
glMaterialfv(GL_FRONT_AND_BACK, GL_DIFFUSE, tp_diffuse);
glMaterialfv(GL_FRONT_AND_BACK, GL_SPECULAR, tp_specular);
glPushMatrix();
glTranslatef(0.0f, 0.0f, -0.6f);
GLUquadricObj *quadric = gluNewQuadric();
gluSphere(quadric, 0.1, 16, 16);
gluDeleteQuadric(quadric);
glPopMatrix();
/*
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
glTranslatef(0.0f, 0.0f, -0.1f);*/
glutCreateMenu(ProcessMenu);
glutAddMenuEntry("position change", 0);
glutAttachMenu(GLUT_RIGHT_BUTTON);
}
void ProcessMenu(int value) {
if (value == 0) {
GLfloat ambient[] = { 0.1,0.1,0.1,1 };
}
glutPostRedisplay();
}
但是我收到了这个错误:
错误C2065'ProcessMenu':未声明的标识符
我应该设置什么?
我是否使用正确的方法来构建PopUp菜单?
如果查看我的所有编码很有用,请查看我的previous, solved question。
