Constructor & Destructor Documentation

◆ IMeshSceneNode()

dcpp::scene::IMeshSceneNode::IMeshSceneNode	(	ISceneNode *	parent,
		ISceneManager *	mgr,
		i32	id,
		const nub::vector3df &	position = `nub::vector3df(0,0,0)`,
		const nub::vector3df &	rotation = `nub::vector3df(0,0,0)`,
		const nub::vector3df &	scale = `nub::vector3df(1,1,1)`
	)

inline

Constructor.

Use setMesh() to set the mesh to display.

Member Function Documentation

◆ addShadowVolumeSceneNode()

virtual IShadowVolumeSceneNode * dcpp::scene::IMeshSceneNode::addShadowVolumeSceneNode	(	const IMesh *	shadowMesh = `0`,
		i32	id = `-1`,
		bool	zfailmethod = `true`,
		f32	infinity = `1000.0f`
	)

pure virtual

The shadow can be rendered using the ZPass or the zfail method. ZPass is a little bit faster because the shadow volume creation is easier, but with this method there occur ugly looking artifacts when the camera is inside the shadow volume. These error do not occur with the ZFail method, but it can have trouble with clipping to the far-plane (it usually works well in OpenGL and fails with other drivers).

Parameters

shadowMesh	Optional custom mesh for shadow volume.
id	Id of the shadow scene node. This id can be used to identify the node later.
zfailmethod	If set to true, the shadow will use the zfail method, if not, zpass is used.
infinity	Value used by the shadow volume algorithm to scale the shadow volume. For zfail shadow volumes on some drivers only suppport finite shadows, so camera zfar must be larger than shadow back cap,which is depending on the infinity parameter). Infinity value also scales by the scaling factors of the model. If shadows don't show up with zfail then try reducing infinity. If shadows are cut-off then try increasing infinity.

Returns: Pointer to the created shadow scene node. This pointer should not be dropped. See IReferenceCounted::drop() for more information.

◆ getMesh()

virtual IMesh * dcpp::scene::IMeshSceneNode::getMesh ( void )

pure virtual

Get the currently defined mesh for display.

Returns: Pointer to mesh which is displayed by this node.

◆ isReadOnlyMaterials()

virtual bool dcpp::scene::IMeshSceneNode::isReadOnlyMaterials ( ) const

pure virtual

Check if the scene node should not copy the materials of the mesh but use them in a read only style.

This flag can be set by setReadOnlyMaterials().

Returns: Whether the materials are read-only.

◆ setMesh()

virtual void dcpp::scene::IMeshSceneNode::setMesh ( IMesh * mesh )

pure virtual

Sets a new mesh to display.

Parameters

mesh	Mesh to display.

◆ setReadOnlyMaterials()

virtual void dcpp::scene::IMeshSceneNode::setReadOnlyMaterials ( bool readonly )

pure virtual

Sets if the scene node should not copy the materials of the mesh but use them in a read only style.

In this way it is possible to change the materials of a mesh causing all mesh scene nodes referencing this mesh to change, too.

Parameters

readonly Flag if the materials shall be read-only.
