StelProjector::StelProjectorParams Struct Reference

Contains all the param needed to initialize a StelProjector. More...

#include <StelProjector.hpp>

Data Fields
Vec4i	viewportXywh
	posX, posY, width, height
float	fov
	FOV in degrees.
bool	gravityLabels
	the flag to use gravity labels or not
float	defaultAngleForGravityText
	a rotation angle to apply to gravity text (only if gravityLabels is set to false)
StelProjectorMaskType	maskType
	The current projector mask.
double	zNear
double	zFar
	Near and far clipping planes.
Vector2< qreal >	viewportCenter
	Viewport center in screen pixel.
Vector2< qreal >	viewportCenterOffset
	Viewport center's offset in fractions of screen width/height. More...
qreal	viewportFovDiameter
	diameter of the FOV disk in pixel
bool	flipHorz
bool	flipVert
	Whether to flip in horizontal or vertical directions.
qreal	devicePixelsPerPixel
	The number of device pixel per "Device Independent Pixels" (value is usually 1, but 2 for mac retina screens)
qreal	widthStretch
	A factor to adapt to special installation setups, e.g. multi-projector with edge blending. Allow to stretch/squeeze projected content. Larger than 1 means the image is stretched wider.

Detailed Description

Contains all the param needed to initialize a StelProjector.

Field Documentation

viewportCenterOffset

Vector2<qreal> StelProjector::StelProjectorParams::viewportCenterOffset

Viewport center's offset in fractions of screen width/height.

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