我正在写光线跟踪器，我的灯光给我带来了问题。我的球体在0,0,0（x，y，z），我的相机在0,0,30和我的将它点亮0,0,40。问题在于光线之上的所有东西都在阴影中，我无法弄清楚为什么。光线之下的所有东西都很好。光线跟踪照明不工作
这里是normals.Normal direction.x * 255，direction.y * 255，direction.z * 255的RGB。
这里是我的光照计算的代码。
public Color Cal_Light2(Color color, Normal normal) {
// Color Maths Stuff
ArrayList<Color> PixelShade = new ArrayList<Color>();
Color Final = new Color();
// Calculate Lighting For Pixel
for (int l = 0; l < LightObjects.size(); l++) {
// Calculate Direction To Each Light(Shadow Ray)
LightObject light = LightObjects.get(l);
Vector3D r_Ori = normal.Origin.Add(normal.Direction.Mul(1E-10));
Vector3D r_Dir = light.Pos.Sub(r_Ori);
r_Dir.normalize();
Ray raytolight = new Ray(r_Ori, r_Dir);
int WAS_HIT = 0;
// Checks If In Light Is Blocked(Shadows)
for (int o = 0; o < GeoObjects.size(); o++) {
GeometricObject NGO = GeoObjects.get(o);
double hit = NGO.hit(raytolight);
if (hit != 0.0) {
WAS_HIT = 1;
}
}
// Light Shades Pixel With Given Info
PixelShade.add(light.ShadePixel(WAS_HIT, normal, r_Dir, color, AmbientLight, DiffuseLight));
}
// Color Averaging
for (int s = 0; s < PixelShade.size(); s++) {
Final.Add(PixelShade.get(s));
}
Final.Divide(PixelShade.size());
// Final
return Final;
}
Here is the light shade pixel.
public Maths.Color ShadePixel(int WAS_HIT, Normal normal, Vector3D r_Dir, Color color, double AmbientLight, double DiffuseLight) {
if(WAS_HIT == 0){
double Dot = normal.Direction.Dot(r_Dir);
Color Color = new Color(color);
double Shade = AmbientLight + DiffuseLight*Dot;
Color.Mul(Shade);
double lightIntesity = Dot*Intensity;
Color lightColor = new Color(color);
lightColor.Mul(lightIntesity);
Color.Add(lightColor);
Color.Divide(2);
return Color;
}else{
Color Color = new Color(color);
double Shade = AmbientLight;
Color.Mul(Shade);
Color.Divide(2);
return Color;
}
}
我在调试运行它，它是说WAS_HIT = 1.So它说，这是打的东西，但我不知道是什么。
