?
ok, hab den fehler beseitigt, wäre nur schön zu wissen wieso das eine geht und das andere nicht. Jetzt siehts so aus:
class Camera
{
public:
Camera()
{
yaw_angle = 0;
pitch_angle = 0;
roll_angle = 0;
position = Vector4D<float>(0.0, 0.0, 0.0);
along = Vector4D<float>(1.0, 0.0, 0.0);
up = Vector4D<float>(0.0, 1.0, 0.0);
forward = Vector4D<float>(0.0, 0.0, -1.0);
}
void ResetRotations()
{
along = Vector4D<float>(1.0, 0.0, 0.0);
up = Vector4D<float>(0.0, 1.0, 0.0);
forward = Vector4D<float>(0.0, 0.0, -1.0);
}
void CalculateRotations()
{
ResetRotations();
// yaw
along = along * cos(yaw_angle) + forward * sin(yaw_angle);
along = normalize(along);
forward = cross(along, up) * -1.0;
// pitch
forward = forward * cos(pitch_angle) + up * sin(pitch_angle);
forward = normalize(forward);
up = cross(forward, along) * -1.0;
// roll
up = up * cos(roll_angle) - along * sin(roll_angle);
up = normalize(up);
along = cross(forward, up);
}
void Yaw(float angle)
{
yaw_angle += angle;
CalculateRotations();
/*along = along * cos(yaw_angle) + forward * sin(yaw_angle);
along = normalize(along);
forward = cross(along, up) * -1.0;*/
}
void Pitch(float angle)
{
pitch_angle += angle;
CalculateRotations();
/*forward = forward * cos(pitch_angle) + up * sin(pitch_angle);
forward = normalize(forward);
up = cross(forward, along) * -1.0;*/
}
void Roll(float angle)
{
roll_angle += angle;
CalculateRotations();
/*up = up * cos(roll_angle) - along * sin(roll_angle);
up = normalize(up);
along = cross(forward, up);*/
}
void Translate(const Vector4D<float> &relative)
{
}
void Move(float amount)
{
position += forward * amount;
}
void Strafe(float amount)
{
position += along * amount;
}
void Fly(float amount)
{
position += up * amount;
}
matrix<> GetMatrix()
{
float x = dot(along, position);
float y = dot(up, position);
float z = dot(forward, position);
float mtx[16] =
{
along.x, up.x, forward.x, 0,
along.y, up.y, forward.y, 0,
along.z, up.z, forward.z, 0,
x, y, z, 1
};
return matrix<>(mtx, 16);
}
private:
float yaw_angle, pitch_angle, roll_angle;
Vector4D<float> position;
Vector4D<float> along;
Vector4D<float> up;
Vector4D<float> forward;
};
