Camera Behind Vehicle

How to set camera exactly behind vehicle

In My case Its carNode and its IAnimatedMeshSceneNode ??? and i am using IrrBullet Raycast Vehicle

The recommended way to do this stuff is to write a custom camera animator. Have a look at the FPS animator and see how it's done.

don't know how to do it can you please elaborate it little more

[Granyte]

i don't know about the specific animator but my solution is to

set the came as a child of the node
then set a camera up vector and a camera target vector

and pass them through the node to be folowed matrix

@grantye plz give me example code

[serengeor]

don't know how to do it can you please elaborate it little more

erm, look at how other camera animators are implemented (in irrlicht source folder), write one yourself that would do the math to maintain it's possition behind the car scene node? AND read the API doc to figure out what does what..
If you have little knowledge of c++ and OOP, that's another question.

@serengeor yeah actually i am thinking there might be some easy way or code available so my time saved .... well i can give it try if no alternative solution is there

[Granyte]

what i gave you is the easy way the code just need to be called befor a render call

Erm, I can't really see how hard and time time consuming can this be.. If you know the basics, it's pretty much +- 1hr of coding depending on how complex you want the movement of the camera to be.

Or you can just update the camera in the main loop.

@Granyte applied your solution but camera looks very unnatural ...

Then do a controller (animator) that would translate to the final position over some time instead of doing it instantly, if that is what you want ofc.

[Granyte]

i don't know how you implemented it but on my end it feel like if the camera is ducktaped on the controled object

it's not the most natural camera but it's quick easy and dirty

but if you wan more advanced stuf you will have to learn how to dow it

Successfully implemented much better camera got idea from bullet Vehicle demo its quite nice

When i have to make a camera move smoothly, i interpolate the original position of the camera target and the intended position of the camera just in the middle, and then, i use that point as the new camera target. The advantage is that the camera moves much more smoothly, the drawback is that if the vehicle moves too fast, it may disappear from the screen, but that only happens with very fast motions, and in most cases, it behaves very well.

I find using smooth(er)step makes for very nice camera transitions.
