Camera.ViewportToWorldPoint

Parámetros

Valor de retorno

Vector3 The 3d vector in World space.

Descripción

Transforms position from viewport space into world space.

Viewport space is normalized and relative to the camera. The bottom-left of the viewport is (0,0); the top-right is (1,1). The z position is in world units from the camera.

Note that ViewportToWorldPoint transforms an x-y screen position into a x-y-z position in 3D space.

Provide the function with a vector where the x-y components of the vector are the screen coordinates and the z component is the distance of the resulting plane from the camera.

// Draw a yellow sphere at top-right corner of the near plane
// for the selected camera in the scene view.
