compute clip status against bounding box

Computes the clip status of a bounding box in global space against the view volume of this camera entity.

Reimplemented from Graphics::GraphicsEntity.

setup camera for perspective field-of-view projection transform

Setup camera as perspective projection.

setup camera for orthogonal projection transform

Setup camera as orthogonal projection.

called when transform matrix changed

We need to keep track of modifications of the transformation matrix.

Reimplemented from Graphics::GraphicsEntity.

update the view projection matrix

Updates the view-projection matrix.

create a clone of the entity

This method is called to create an exact clone of this graphics entity. The new entity will not be attached to a stage.

called when entity is created

Activate the entity. This method is called when the entity is created an attached to the graphics server. During OnActivate() the entity should perform any one-time initializations.

Reimplemented in Graphics::ActorEntity, and Graphics::ModelEntity.

called when attached to Stage

This method is called when the graphics entity is attached to a stage. An entity may only be attached to one stage at any time, but can be attached to different stages during its lifetime. Attachging an entity to a stage may be relatively slow because the entity must be inserted into the cell hierarchy.

called when removed from Stage

This method is called when the graphics entity is removed from a stage.

called when attached to a Cell

This method is called when the graphics entity is attached to a cell inside a stage. When entity travel through the graphics world, they will be remove and attached themselves from and to Cells as they cross Cell borders.

called when removed from a Cell

Called when the graphics entity is removed from a cell inside a stage.

called when the entity becomes visible

This method is called from the SetVisible() method when the entity changes from invisible to visible state.

called when the entity becomes invisible

This method is called from the SetVisible() method when the entity changes from visible to invisible state.

called to update the entity before rendering

This method is called on the graphics entity to update itself, for instance to implement hierarchy animation or particle updates.

Reimplemented in Graphics::ActorEntity, and Graphics::ModelEntity.

called before the entity is rendered

This method is called on the graphics entity to render itself. This method will only be called if the entity is visible through the camera of the currently rendered View.

called to render a debug visualization of the entity

This method is called on the graphics entity to render a debug visualization of itself.

Reimplemented in Graphics::ModelEntity.

update our position in the cell hierarchy

This method is called from OnUpdate() when either the entity's transformation or bounding box has changed. It checks if the entity still fits into its current cell, and if not, moves the entity in a new cell.

get the current refcount

Return the current refcount of the object.

increment refcount by one

Increment the refcount of the object.

decrement refcount and destroy object if refcount is zero

Decrement the refcount and destroy object if refcount is zero.

get the class name

Get the class name of the object.

get the class FourCC code

Get the class FourCC of the object.

dump refcounting leaks, call at end of application (NEBULA3_DEBUG builds only!)

This method should be called as the very last before an application exits.
