On the normalization of camera rotation interpolation

When making a rotating camera , We often encounter interpolation from the current angle to a specific angle , But there will be an angle greater than 360 The situation of , Therefore, it is necessary to find the nearest interpolation angle for interpolation .

Therefore, it is necessary to normalize the angle value and target value before interpolation . All in one -180 To 180 Between , Then interpolate .

Go straight to the code ：

    AngleNormalize(angle, rangecenter=0){

        angle = (angle % 6.28);

        if(angle<-3.14+rangecenter) 

            angle += 6.28;

        else if(angle>3.14+rangecenter)

            angle -= 6.28;

        return angle;

    }

After being processed by this function, the angles will return to the same interval , The interpolation animation will not rotate several times .
