How does the parent rotation affects the child specifically?

Question

Hi Everyone.Recently, I found a little thing in parenting relationship. I'll illustrate my scenario.I have a little 3d solid and a 3d null. Here are their rotation and orientation value:After I parent the solid to the 3d null(named 'Parent'), the child's orientation value changes to keep the original  transform status. That is nothing special.But here comes the question: How can I get the result of [338.0,353.8,307.1] from [25,0,0]? Is there a formula to calculate this? I guess I'm gonna need it in my project.And here is another interesting thing: the camera won't change its orientation value to keep its original transform after parenting.Here is the rotation and orientation value before parenting:And here is the camera in custom view:After parenting, the rotation and orientation value didn't change, so it is impossible that the camera will still maintain its original transform. So it jumped a little bit. Like this:It seems that the same holds true for spot light. I guess it is because they both have point of interest?(Not sure)So I think if I can make out how the child's orientation value is affected by the parent's rotation, I can make compensation for the jumping issue of camera parenting. How could I achieve this via expression or scripting?Any reply will be appreciated.Aaron

1. Orientation: Parent rotation changes the orientation of the child object within the app. 2. Position: The child's position relative to the parent may shift depending on the rotation. 3. Scale: The scale of the child object may appear distorted if the parent is rotated unevenly. 4. Alignment: The alignment of the child object with other elements in the app could be altered. 5. Perspective: Rotation of the parent can affect the perspective from which the child is viewed. 6. Collision Detection: Changes in orientation may impact collision detection between the child and other objects in the app. 7. Animation: Rotation of the parent may affect any animations applied to the child object.8. User Interaction: The way users interact with the child object may change based on the parent's rotation. 9. Rendering: The rendering of the child object may differ depending on the parent's rotation angle. 10. Physics Simulation: Parent rotation can influence the physics simulation applied to the child object. 11. Constraints: Constraints applied to the child object may behave differently when the parent is rotated. 12. Transformations: Any transformations applied to the child object may be compounded by the parent's rotation. 13. Z-Order: The z-order of the child object in relation to other elements in the app may be affected by the parent's rotation. 14. Shadows and Lighting: Changes in the parent's rotation can alter the appearance of shadows and lighting on the child object. 15. Performance: Excessive parent rotation may impact the app's performance, especially if complex child objects are involved.
