StelProjector::StelProjectorParams Struct Reference

#include <StelProjector.hpp>

Data Fields
Vector4< int >	viewportXywh
float	fov
	posX, posY, width, height
bool	gravityLabels
	FOV in degrees.
float	defaultAngleForGravityText
	the flag to use gravity labels or not
StelProjectorMaskType	maskType
	a rotation angle to apply to gravity text (only if gravityLabels is set to false)
double	zNear
	The current projector mask.
double	zFar
Vector2< qreal >	viewportCenter
	Near and far clipping planes.
Vector2< qreal >	viewportCenterOffset
	Viewport center in screen pixel.
qreal	viewportFovDiameter
	Viewport center's offset in fractions of screen width/height. More...
bool	flipHorz
	diameter of the FOV disk in pixel
bool	flipVert
qreal	devicePixelsPerPixel
	Whether to flip in horizontal or vertical directions.
qreal	widthStretch
	The number of device pixel per "Device Independent Pixels" (value is usually 1, but 2 for mac retina screens)

Detailed Description

Contains all the param needed to initialize a StelProjector

viewportFovDiameter

qreal StelProjector::StelProjectorParams::viewportFovDiameter

Usable e.g. in cylindrical projection to move horizon down. Currently only Y shift is fully implemented, X shift likely not too meaningful.
