私は5つの顔のボックスを作成し、その中にボールを入れて、ボックスの中で跳ね返ることができました。私はglOrthoを使ってこれを作成しました。gluPerspectiveはすべてのオブジェクトを表示していません
自分のコースに3Dブリックブレーカースタイルのゲームを作成したいので、カメラをボックスに入れたいと思います。私はglOrthoからgluPerspectiveに変更しました。私はボックスを正しくレンダリングするためにいくつかの値を変更しなければならなかったが、私が原点に置かない限りボールは欠落しているようだ。
これは私の値の初期化です：
void variableInits(){
//Floor Plane
pl1.pos.x = 0; pl1.pos.y = -50; pl1.pos.z = 0;
pl1.norm.x = 0; pl1.norm.y = 1; pl1.norm.z = 0;
//Ceiling Plane
pl2.pos.x = 0; pl2.pos.y = 50; pl2.pos.z = 0;
pl2.norm.x = 0; pl2.norm.y = -1; pl2.norm.z = 0;
//Right Wall Plane
pl3.pos.x = 50; pl3.pos.y = 0; pl3.pos.z = 0;
pl3.norm.x = -1; pl3.norm.y = 0; pl3.norm.z = 0;
//Left Wall Plane
pl4.pos.x = -50; pl4.pos.y = 0; pl4.pos.z = 0;
pl4.norm.x = 1; pl4.norm.y = 0; pl4.norm.z = 0;
//Back Wall Plane
pl5.pos.x = 0; pl5.pos.y = 0; pl5.pos.z = -100;
pl5.norm.x = 0; pl5.norm.y = 0; pl5.norm.z = 1;
//Paddle Plane
paddlePlane.max.x=.25; paddlePlane.max.y=.25; paddlePlane.max.z=1;
paddlePlane.min.x=-.25; paddlePlane.min.y=-.25; paddlePlane.min.z=1;
paddlePlane.normals.x=0; paddlePlane.normals.y=0;paddlePlane.normals.z=-0;
//Ball Init
b1.radius = 10;
b1.pathDirection.x = 0; b1.pathDirection.y = 0; b1.pathDirection.z = 0;
b1.pos.x = 0; b1.pos.y = 0, b1.pos.z = -25;
}
だから私のボールが上-25 Z軸の値が10の半径で描く必要があります。残念ながらそれはしません。
多分私のgluPerspectiveコールの問題ですか？
void reshape(int width, int height)
{
if (height==0)
{
height=1;
}
glViewport(0,0,width,height);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluPerspective(45.0f,(GLfloat)width/(GLfloat)height,0.0f,50.0f);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
}
