Detailed Description

Orthographic camera.

Definition at line 168 of file Camera.h.

Constructor & Destructor Documentation

◆ OrthoCamera()

OrthoCamera::OrthoCamera ( const CameraParams & data )

explicit

Definition at line 49 of file Camera.cpp.

Member Function Documentation

◆ autoSetup()

void OrthoCamera::autoSetup ( const Storage & storage )

overridevirtual

Initializes the camera, using the provided particle storage.

Implements ICamera.

Definition at line 99 of file Camera.cpp.

◆ clone()

virtual AutoPtr<ICamera> OrthoCamera::clone ( ) const

inlineoverridevirtual

Todo:: revert to ClonePtr!

Implements ICamera.

Definition at line 212 of file Camera.h.

◆ getCutoff()

Optional< float > OrthoCamera::getCutoff ( ) const

overridevirtual

Returns the clipping distance from plane passing through origin, perpendicular to camera direction.

If no clipping is used, the function returns NOTHING. Useful to view a section through a body rather than its surface.

Implements ICamera.

Definition at line 152 of file Camera.cpp.

◆ getFrame()

AffineMatrix OrthoCamera::getFrame ( ) const

overridevirtual

Returns the transformation matrix converting camera space to world space.

In the camera space, camera direction is aligned with the z-axis, y-axis corresponds to the up-vector and x-axis is perpendicular, i.e. left-vector.

Implements ICamera.

Definition at line 140 of file Camera.cpp.

◆ getSize()

Pixel OrthoCamera::getSize ( ) const

overridevirtual

Returns the current resolution of the camera.

Implements ICamera.

Definition at line 136 of file Camera.cpp.

◆ getTarget()

Vector OrthoCamera::getTarget ( ) const

overridevirtual

Returns the current target point of the camera.

Implements ICamera.

Definition at line 144 of file Camera.cpp.

◆ getUpVector()

Vector OrthoCamera::getUpVector ( ) const

overridevirtual

Returns the reference "up" direction of the camera.

Implements ICamera.

Definition at line 148 of file Camera.cpp.

◆ getWorldToPixel()

Optional< float > OrthoCamera::getWorldToPixel ( ) const

overridevirtual

Returns the world-to-pixel ratio.

Implements ICamera.

Definition at line 156 of file Camera.cpp.

◆ pan()

void OrthoCamera::pan ( const Pixel offset )

overridevirtual

Moves the camera by relative offset in image space.

Implements ICamera.

Definition at line 202 of file Camera.cpp.

◆ project()

Optional< ProjectedPoint > OrthoCamera::project ( const Vector & r ) const

overridevirtual

Returns projected position of particle on the image.

If the particle is outside of the image region or is clipped by the projection, returns NOTHING.

Implements ICamera.

Definition at line 109 of file Camera.cpp.

◆ resize()

void OrthoCamera::resize ( const Pixel newSize )

overridevirtual

Changes the image size.

Implements ICamera.

Definition at line 209 of file Camera.cpp.

◆ setCutoff()

void OrthoCamera::setCutoff ( const Optional< float > newCutoff )

overridevirtual

Modifies the clipping distance of the camera.

The clipping can be disabled by passing NOTHING.

Implements ICamera.

Definition at line 160 of file Camera.cpp.

◆ setPosition()

void OrthoCamera::setPosition ( const Vector & newPosition )

overridevirtual

Moves the camera to new position in world space.

Implements ICamera.

Definition at line 175 of file Camera.cpp.

◆ setTarget()

void OrthoCamera::setTarget ( const Vector & newTarget )

overridevirtual

Implements ICamera.

Definition at line 181 of file Camera.cpp.

◆ transform()

void OrthoCamera::transform ( const AffineMatrix & matrix )

overridevirtual

Transforms the current view by given matrix.

This replaces previous transformation matrix, i.e. subsequent calls do not accumulate.

Parameters

matrix Transform matrix applied to the camera.

Implements ICamera.

Definition at line 187 of file Camera.cpp.

◆ unproject()

Optional< CameraRay > OrthoCamera::unproject ( const Coords & coords ) const

overridevirtual

Returns a ray in particle coordinates corresponding to given coordinates in the image plane.

Implements ICamera.

Definition at line 132 of file Camera.cpp.

◆ zoom()

void OrthoCamera::zoom	(	const Pixel	fixedPoint,
		const float	magnitude
	)

overridevirtual

Parameters

Applies zoom to the camera.

This is usually equivalent to transforming the view with scaling matrix, alhough it can be implemented differently.

Parameters

fixedPoint	Point that remains fixed after the zoom (for magnitude != 1, there is exactly one)
magnitude	Relative zoom amount, value <1 means zooming out, value >1 means zooming in.

Implements ICamera.
