Arc Camera that rotate 3 ways

[saltemishel]

Hi All,

It seems that I can rotate along the Alpha and Beta direction using the arc camera.

Is it possible for me to rotate the camera by 360 based on the player's viewing angle? (something like the screen rotates clockwise/counter-clockwise)

Or any other camera recommendation?

Thanks!

you most manage it by upVector

@NasimiAsl Thanks! It works like a charm, how do I remove the limit so it can rotate 360 degrees?

[NasimiAsl]

you most calculate that and use math   i try write sample to have it after after office to you ( after 6 hours ) but you can try yourself too

1. calculate a vector between camera and target position

2. rotate your up vector to cross of that

3. add rotation matrix  to  find new up vector  when you  rotate around of (camera - target vector  ) 

and maybe some others see and help you faster @adam @jerome @Wingnut ...

@NasimiAsl Ah I see, I've figured it out.

I've set it to be the actual equation instead of adding.

this.ti+=0.05;

this.camera.upVector.y = Math.sin(this.ti/180*Math.PI);

this.camera.upVector.x= Math.cos(this.ti/180*Math.PI);

It works now.

 

Thanks!
