Detailed Description

Scene Node which is a (controllable) camera.

The whole scene will be rendered from the cameras point of view. Because the ICameraSceneNode is a SceneNode, it can be attached to any other scene node, and will follow its parents movement, rotation and so on.

Member Function Documentation

◆ bindTargetAndRotation()

virtual void irr::scene::ICameraSceneNode::bindTargetAndRotation ( bool bound )

pure virtual

Binds the camera scene node's rotation to its target position and vice versa, or unbinds them.

When bound, calling setRotation() will update the camera's target position to be along its +Z axis, and likewise calling setTarget() will update its rotation so that its +Z axis will point at the target point. FPS camera use this binding by default; other cameras do not.

Parameters

bound True to bind the camera's scene node rotation and targeting, false to unbind them.

◆ setInputReceiverEnabled()

virtual void irr::scene::ICameraSceneNode::setInputReceiverEnabled ( bool enabled )

◆ setProjectionMatrix()

virtual void irr::scene::ICameraSceneNode::setProjectionMatrix	(	const core::matrix4 &	projection,
		bool	isOrthogonal = `false`
	)

pure virtual

Sets the projection matrix of the camera.

The core::matrix4 class has some methods to build a projection matrix. e.g: core::matrix4::buildProjectionMatrixPerspectiveFovLH. Note that the matrix will only stay as set by this method until one of the following Methods are called: setNearValue, setFarValue, setAspectRatio, setFOV. NOTE: The frustum is not updated before render() is called unless you explicitly call updateMatrices()

Parameters

projection	The new projection matrix of the camera.
isOrthogonal	Set this to true if the matrix is an orthogonal one (e.g. from matrix4::buildProjectionMatrixOrtho).

◆ setRotation()

virtual void irr::scene::ICameraSceneNode::setRotation ( const core::vector3df & rotation )

pure virtual

Sets the rotation of the node.

This only modifies the relative rotation of the node. If the camera's target and rotation are bound (

See also: bindTargetAndRotation() ) then calling this will also change the camera's target to match the rotation.

Parameters

rotation New rotation of the node in degrees.

Reimplemented from irr::scene::ISceneNode.

◆ setTarget()

virtual void irr::scene::ICameraSceneNode::setTarget ( const core::vector3df & pos )

pure virtual

Sets the look at target of the camera.

If the camera's target and rotation are bound (

See also: bindTargetAndRotation() ) then calling this will also change the camera's scene node rotation to match the target. Note that setTarget uses the current absolute position internally, so if you changed setPosition since last rendering you must call updateAbsolutePosition before using this function.

Parameters

pos	Look at target of the camera, in world co-ordinates.

◆ setUpVector()

virtual void irr::scene::ICameraSceneNode::setUpVector ( const core::vector3df & pos )

pure virtual

Sets the up vector of the camera.

Parameters

pos	New upvector of the camera.

◆ setViewMatrixAffector()

virtual void irr::scene::ICameraSceneNode::setViewMatrixAffector ( const core::matrix4 & affector )

pure virtual

Sets a custom view matrix affector.

The matrix passed here, will be multiplied with the view matrix when it gets updated. This allows for custom camera setups like, for example, a reflection camera.

Parameters

affector The affector matrix.

◆ updateMatrices()

virtual void irr::scene::ICameraSceneNode::updateMatrices ( )

pure virtual

Updates the matrices without uploading them to the driver.
