Camera orbit around an arbitrary point

[anon_96968503]

Hi,

I checked the mouse orbit code it makes the camera to orbit around the origin. I want my camera to pan to a new position and orbit it with respect to it.

A member from GameDev suggests the following

Orbiting the camera is equivalent to rotating the camera location around the target position. There is a transformation matrix that allows you to rotate a point about an angle around an arbitrary axis.

Let’s call this matrix R, you camera position c and you target position t. Orbiting the camera is done as follow:

c’ = translate(t)Rtranslate(-t)*c

Where c’ is the new position of your camera after orbiting and translate( . ) is a translation matrix.

You still have to choose around which axis you want to orbit

Could any one suggest some details on how to implement it or any other better approach

Thanks

Personally used Transform.RotateAround when doing an orbit script recently. Might do what you want too.

Ahh, transform.RotateAround() very useful, thanks.
