Member Function Documentation

◆ autoSetup()

void PanoCameraBase::autoSetup ( const Storage & storage )

overridevirtual

Initializes the camera, using the provided particle storage.

Implements ICamera.

Definition at line 366 of file Camera.cpp.

◆ getCutoff()

Optional< float > PanoCameraBase::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 396 of file Camera.cpp.

◆ getFrame()

AffineMatrix PanoCameraBase::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 384 of file Camera.cpp.

◆ getSize()

Pixel PanoCameraBase::getSize ( ) const

overridevirtual

Returns the current resolution of the camera.

Implements ICamera.

Definition at line 380 of file Camera.cpp.

◆ getTarget()

Vector PanoCameraBase::getTarget ( ) const

overridevirtual

Returns the current target point of the camera.

Implements ICamera.

Definition at line 388 of file Camera.cpp.

◆ getUpVector()

Vector PanoCameraBase::getUpVector ( ) const

overridevirtual

Returns the reference "up" direction of the camera.

Implements ICamera.

Definition at line 392 of file Camera.cpp.

◆ getWorldToPixel()

Optional< float > PanoCameraBase::getWorldToPixel ( ) const

overridevirtual

Returns the world-to-pixel ratio.

Implements ICamera.

Definition at line 401 of file Camera.cpp.

◆ pan()

void PanoCameraBase::pan ( const Pixel offset )

overridevirtual

Moves the camera by relative offset in image space.

Implements ICamera.

Definition at line 423 of file Camera.cpp.

◆ project()

Optional< ProjectedPoint > PanoCameraBase::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 376 of file Camera.cpp.

◆ resize()

void PanoCameraBase::resize ( const Pixel newSize )

overridevirtual

Changes the image size.

Implements ICamera.

Definition at line 427 of file Camera.cpp.

◆ setCutoff()

void PanoCameraBase::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 405 of file Camera.cpp.

◆ setPosition()

void PanoCameraBase::setPosition ( const Vector & newPosition )

overridevirtual

Moves the camera to new position in world space.

Implements ICamera.

Definition at line 411 of file Camera.cpp.

◆ setTarget()

void PanoCameraBase::setTarget ( const Vector & newTarget )

overridevirtual

Implements ICamera.

Definition at line 415 of file Camera.cpp.

◆ transform()

void PanoCameraBase::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 419 of file Camera.cpp.

◆ update()

void PanoCameraBase::update ( )

protectedvirtual

Definition at line 432 of file Camera.cpp.

◆ zoom()

void PanoCameraBase::zoom	(	const Pixel	UNUSEDfixedPoint,
		const float	magnitude
	)

overridevirtual

Definition at line 407 of file Camera.cpp.
