OnMarkedDirty()

void Urho3D::Camera::OnMarkedDirty ( Node *  node )

overrideprotectedvirtual

Handle node transform being dirtied.

Reimplemented from Urho3D::Component.

OnNodeSet()

void Urho3D::Camera::OnNodeSet ( Node *  node )

overrideprotectedvirtual

Handle node being assigned.

Reimplemented from Urho3D::Component.

ScreenToWorldPoint()

Vector3 Urho3D::Camera::ScreenToWorldPoint

(

const Vector3 &

screenPos

)

const

Convert normalized screen coordinates (0 - 1) and distance along view Z axis (in Z coordinate) to a world space point. The distance can not be closer than the near clip plane.

Note that a HitDistance() from the camera screen ray is not the same as distance along the view Z axis, as under a perspective projection the ray is likely to not be Z-aligned.

SetProjection()

void Urho3D::Camera::SetProjection

(

const Matrix4 &

projection

)

Set custom projection matrix, which should be specified in D3D convention with depth range 0 - 1. Disables auto aspect ratio.

Change any of the standard view parameters (FOV, far clip, zoom, etc.) to revert to the standard projection. Note that the custom projection is not serialized or replicated through the network.
