Calculating the angular distance (FOV delta) between your current camera view angles and a target entity is essential for targeting logic and smooth mouse interpolation.
The Mathematical Formula:
1. Compute the direction vector:
2. Calculate target Pitch & Yaw:
3. Normalize angle differences to [-180, 180] degrees:
4. Calculate Euclidean FOV:
The Mathematical Formula:
1. Compute the direction vector:
CPP
delta = targetPos - cameraPos2. Calculate target Pitch & Yaw:
CPP
float pitch = -atan2(delta.z, hypot(delta.x, delta.y)) * (180.0f / M_PI);
float yaw = atan2(delta.y, delta.x) * (180.0f / M_PI);3. Normalize angle differences to [-180, 180] degrees:
CPP
Vector2 NormalizeAngles(Vector2 angle) {
while (angle.x > 89.0f) angle.x -= 180.0f;
while (angle.x < -89.0f) angle.x += 180.0f;
while (angle.y > 180.0f) angle.y -= 360.0f;
while (angle.y < -180.0f) angle.y += 360.0f;
return angle;
}4. Calculate Euclidean FOV:
CPP
float GetFOV(const Vector2& currentAngles, const Vector2& targetAngles) {
Vector2 deltaAngle = NormalizeAngles({ targetAngles.x - currentAngles.x, targetAngles.y - currentAngles.y });
return sqrt(deltaAngle.x * deltaAngle.x + deltaAngle.y * deltaAngle.y);
}
