Detailed Description

Camera with no perspective projection. Objects far away will appear as large as objects close.

Member Function Documentation

◆ calculateProjectionMatrix()

virtual mat4 inviwo::OrthographicCamera::calculateProjectionMatrix ( ) const

overrideprotectedvirtual

Calculate and return the projection matrix for the camera.

Implement this function to provide your own projection computation functionality. For example orthogonal or perspective projection. This function will be called when the projection matrix is invalid.

See also: PerspectiveCamera; OrthographicCamera

Implements inviwo::Camera.

◆ clone()

virtual OrthographicCamera * inviwo::OrthographicCamera::clone ( ) const

overridevirtual

Implements inviwo::Camera.

◆ configureProperties()

virtual void inviwo::OrthographicCamera::configureProperties	(	CameraProperty &	cameraProperty,
		bool	attach )

overridevirtual

Reimplemented from inviwo::Camera.

◆ deserialize()

virtual void inviwo::OrthographicCamera::deserialize ( Deserializer & d )

overridevirtual

Reimplemented from inviwo::Camera.

◆ equal()

virtual bool inviwo::OrthographicCamera::equal ( const Camera & other ) const

overrideprotectedvirtual

Implements inviwo::Camera.

◆ getClassIdentifier()

virtual std::string_view inviwo::OrthographicCamera::getClassIdentifier ( ) const

overridevirtual

Implements inviwo::Camera.

◆ getClipPosFromNormalizedDeviceCoords()

virtual vec4 inviwo::OrthographicCamera::getClipPosFromNormalizedDeviceCoords ( const vec3 & ndcCoords ) const

overridevirtual

Convert from normalized device coordinates (xyz in [-1 1]) to clip coordinates, where z value of -1 correspond to the near plane and 1 to the far plane. Coordinates outside of the [-1 1]^3 range will be clipped.

Parameters

ndcCoords xyz clip-coordinates in [-1 1]^3, and the clip w-coordinate used for perspective division.

Returns: Clip space position

Reimplemented from inviwo::Camera.

◆ serialize()

virtual void inviwo::OrthographicCamera::serialize ( Serializer & s ) const

overridevirtual

Reimplemented from inviwo::Camera.

◆ updateFrom()

virtual void inviwo::OrthographicCamera::updateFrom ( const Camera & source )

overridevirtual

Reimplemented from inviwo::Camera.

◆ zoom()

virtual void inviwo::OrthographicCamera::zoom	(	float	factor,
		std::optional< mat4 >	boundingBox )

overridevirtual

Implements inviwo::Camera.
