Same size in view Independent from distance

Dear all,

I want to scale an object so that it has every time the same visible size in the view of the main camera, independent from the distance to the camera. My problem is, that I don't know the size of the object. I know the scale factor, but not the real size. I played with the bounding box, but I can't solve the problem. The visible size is just varying.

Maybe You know a simple way to keep the visible size of an object in the view constant regardless of the distance to the camera.

Thank You very much,
Ray

 

I am assuming you're using a perspective view.

Remember the original scale and distance of the object when it's the perfect size.

Any time after that, you can adjust the scale proportional to the current distance. If the distance doubles, the scale should double to maintain the same camera-apparent size.

 

Sure, You're right, and I'm a fool. Thank You very much.

 

How do you find the distance of the object when it is the perfect size?
