SceneInfo Struct Reference

Contains all the metadata necessary for a Scenery3d scene, and can be loaded from special .ini files in a scene's folder. More...

#include <SceneInfo.hpp>

Public Member Functions
bool	hasLocation () const
	Returns true if the location object is valid.
bool	hasLookAtFOV () const
	Returns true if the lookat_fov is valid.
QString	getLocalizedHTMLDescription () const
	Tries to find a description. More...

Static Public Member Functions
static bool	loadByID (const QString &id, SceneInfo &info)
	Loads the scene metadata associated with this ID (directory) into the given object. Returns true on success.
static bool	loadByName (const QString &name, SceneInfo &info)
	Convenience method that finds the ID for the given name and calls loadByID.
static QString	getIDFromName (const QString &name)
	Returns the ID for the given scene name. More...
static QStringList	getAllSceneIDs ()
	Returns all available scene IDs.
static QStringList	getAllSceneNames ()
	Returns all available scene names.
static QMap< QString, QString >	getNameToIDMap ()
	Builds a mapping of available scene names to the folders they are contained in, similar to the LandscapeMgr's method.

Data Fields
bool	isValid
	If this is a valid sceneInfo object loaded from file.
QString	id
	ID of the scene (relative directory)
QString	fullPath
	The full path to the scene's folder. Other paths (model files) are to be seen relative to this path.
QString	name
	Name of the scene.
QString	author
	Author of the scene.
QString	description
	A description, which can be displayed in the GUI - supporting HTML tags! Note that this description, as stored in the scenery3d.ini, is only meant as a fallback. More...
QString	copyright
	Copyright string.
QString	landscapeName
	The name of the landscape to switch to. The landscape's position is applied on loading.
QString	modelScenery
	The file name of the scenery .obj model.
QString	modelGround
	The file name of the optional seperate ground model (used as a heightmap for walking)
QString	vertexOrder
	Optional string depicting vertex order of models (XYZ, ZXY, ...)
StelOBJ::VertexOrder	vertexOrderEnum
	The vertex order of the corresponding OBJ file.
float	camNearZ
	Distance to cam near clipping plane. Default 0.3.
float	camFarZ
	Distance to cam far clipping plane. Default 10000.0.
float	shadowFarZ
	An optional shadow far clipping plane, constraining the shadowmaps to a smaller region than is visible. More...
float	shadowSplitWeight
	Weighting of the shadow frustum splits between uniform (at 0) and logarithmic (at 1) splits When -1, should be calculated from the scene using the old algorithm.
QSharedPointer< StelLocation >	location
	Optional more accurate location information, which will override the landscape's position.
Vec3f	lookAt_fov
	Optional initial look-at vector (azimuth, elevation and FOV in degrees)
double	eyeLevel
	The height at which the observer's eyes are placed. Default 1.65.
QString	gridName
	The name of the grid space for displaying the world positon.
Vec3d	modelWorldOffset
	Offset of the center of the model in a given grid space.
Vec3d	startWorldOffset
	The world grid space offset where the observer is placed upon loading.
Vec3d	relativeStartPosition
	Relative start position in model space, calculated from the world offset and start offset with Z rotation, etc.
bool	altitudeFromModel
	If true, it indicates that the model file's bounding box is used for altitude calculation.
bool	startPositionFromModel
	If true, it indicates that the model file's bounding box is used for starting position calculation.
bool	groundNullHeightFromModel
	If true, it indicates that the model file's bounding box is used for starting height calculation.
Mat4d	obj2gridMatrix
	If only a non-georeferenced OBJ can be provided, you can specify a matrix via .ini/[model]/obj_world_trafo. More...
Mat4d	zRotateMatrix
	The vertical axis rotation that must be applied to the scene, for meridian convergence. More...
double	groundNullHeight
	The height value outside the ground model's heightmap, or used if no ground model exists.
float	transparencyThreshold
	Threshold for cutout transparency (no blending). Default is 0.5f.
bool	sceneryGenerateNormals
	Recalculate normals of the scene from face normals? Default false.
bool	groundGenerateNormals
	Recalculate normals of the ground from face normals? Default false.

Static Public Attributes
static const QString	SCENES_PATH
	The folder for scenery is found here.

Detailed Description

Member Function Documentation

static QString SceneInfo::getIDFromName ( const QString &  name )

static

If multiple scenes exist with the same name, the first one found is returned. If no scene is found with this name, an empty string is returned.

QString SceneInfo::getLocalizedHTMLDescription

(

)

const

<language>.utf8 file for this scene, and returns its contents. If no such file exists, the description.en.utf8 is checked. If this is also missing, a null QString is returned. Consider using the value of SceneInfo::description in this case.

Field Documentation

QString SceneInfo::description

The better way would be to create description.<lang>.utf8 files in the scene's folder. This can then be retrieved using getLocalizedHTMLDescription.

Mat4d SceneInfo::obj2gridMatrix

This will be applied to make sure that X=Grid-East, Y=Grid-North, Z=height.

float SceneInfo::shadowFarZ

Must be smaller or equal to camFarZ. Default equals camFarZ.

Mat4d SceneInfo::zRotateMatrix

This is calculated from other fields in the file.
