Member Function Documentation
| ClipStatus::Type Graphics::CameraEntity::ComputeClipStatus | ( | const Math::bbox & | box | ) | [virtual] |
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.
| void Graphics::CameraEntity::SetupPerspectiveFov | ( | float | fov_, | |
| float | aspect_, | |||
| float | zNear_, | |||
| float | zFar_ | |||
| ) |
setup camera for perspective field-of-view projection transform
Setup camera as perspective projection.
| void Graphics::CameraEntity::SetupOrthogonal | ( | float | w, | |
| float | h, | |||
| float | zNear_, | |||
| float | zFar_ | |||
| ) |
setup camera for orthogonal projection transform
Setup camera as orthogonal projection.
| void Graphics::CameraEntity::OnTransformChanged | ( | ) | [protected, virtual] |
called when transform matrix changed
We need to keep track of modifications of the transformation matrix.
Reimplemented from Graphics::GraphicsEntity.
| void Graphics::CameraEntity::UpdateViewProjMatrix | ( | ) | [protected] |
update the view projection matrix
Updates the view-projection matrix.
| Ptr< GraphicsEntity > Graphics::GraphicsEntity::CreateClone | ( | ) | const [protected, virtual, inherited] |
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.
| void Graphics::GraphicsEntity::OnActivate | ( | ) | [protected, virtual, inherited] |
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.
| void Graphics::GraphicsEntity::OnAttachToStage | ( | const Ptr< Stage > & | s | ) | [protected, virtual, inherited] |
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.
| void Graphics::GraphicsEntity::OnRemoveFromStage | ( | ) | [protected, virtual, inherited] |
called when removed from Stage
This method is called when the graphics entity is removed from a stage.
| void Graphics::GraphicsEntity::OnRemoveFromCell | ( | ) | [protected, virtual, inherited] |
called when removed from a Cell
Called when the graphics entity is removed from a cell inside a stage.
| void Graphics::GraphicsEntity::OnShow | ( | ) | [protected, virtual, inherited] |
called when the entity becomes visible
This method is called from the SetVisible() method when the entity changes from invisible to visible state.
| void Graphics::GraphicsEntity::OnHide | ( | ) | [protected, virtual, inherited] |
called when the entity becomes invisible
This method is called from the SetVisible() method when the entity changes from visible to invisible state.
| void Graphics::GraphicsEntity::OnUpdate | ( | ) | [protected, virtual, inherited] |
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.
| void Graphics::GraphicsEntity::OnRender | ( | ) | [protected, virtual, inherited] |
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.
| void Graphics::GraphicsEntity::OnRenderDebug | ( | ) | [protected, virtual, inherited] |
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.
| void Graphics::GraphicsEntity::UpdatePositionInCellTree | ( | ) | [protected, inherited] |
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.
| int Core::RefCounted::GetRefCount | ( | ) | const [inline, inherited] |
get the current refcount
Return the current refcount of the object.
| void Core::RefCounted::AddRef | ( | ) | [inline, inherited] |
increment refcount by one
Increment the refcount of the object.
| void Core::RefCounted::Release | ( | ) | [inline, inherited] |
decrement refcount and destroy object if refcount is zero
Decrement the refcount and destroy object if refcount is zero.
| const Util::String & Core::RefCounted::GetClassName | ( | ) | const [inline, inherited] |
get the class name
Get the class name of the object.
| Util::FourCC Core::RefCounted::GetClassFourCC | ( | ) | const [inline, inherited] |
get the class FourCC code
Get the class FourCC of the object.
| void Core::RefCounted::DumpRefCountingLeaks | ( | ) | [static, inherited] |
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.
