SceneCameraState
Engine/source/scene/sceneCameraState.h
An object that combines all the state that is relevant to looking into the scene from a particular point of view.
Protected Attributes
The projection matrix.
World-space vector representing the view direction.
The inverse of the frustum's transform stored here for caching.
Protected Functions
Internal constructor.
Public Functions
Return the camera frustum.
Return the projection transform.
Return the world-space view vector.
Return the screen-space viewport rectangle.
Return the view position. This is a shortcut for getFrustum().getPosition().
Return the view->world transform. This is a shortcut for getFrustum().getTransform().
Return the world->view transform.
Public Static Functions
fromGFX()
Capture the view state from the current GFX state.
fromGFXWithViewport(const RectI & viewport)
Detailed Description
An object that combines all the state that is relevant to looking into the scene from a particular point of view.
Protected Attributes
Frustum mFrustum
The viewing frustum.
MatrixF mProjectionMatrix
The projection matrix.
Point3F mViewDirection
World-space vector representing the view direction.
RectI mViewport
The screen-space viewport rectangle.
MatrixF mWorldViewMatrix
The inverse of the frustum's transform stored here for caching.
Protected Functions
