Fly Process

The process allows you to move the camera around a scene. If we imagine that the camera was an observer, then he would appear to “fly” through a scene. Also when the process is run, it activates the first person camera process. To make the camera “fly”, you should press the left mouse button and then move your mouse. To manage the camera in first person mode, you should press the right mouse button and then move your mouse.

Warning

Fly process will change the current projection to perspective if it is not.

Below we will consider the process.

Features

FlyProcess type (TypeScript):

export type FlyProcess = {

    options?: FlyOptions
    events?: {
        onStart?: ()=>void
        onEnd?: ()=>void
        onProjectionChanged?: (prj: CameraProjection) => void
    }
}

export type FlyOptions = {
    forwardSpeed?: number
    sideSpeed?: number
    constant?: boolean
}
