void Planet::draw ( StelCore *  core,
class StelRenderer *  renderer,
float  maxMagLabels,
const QFont &  planetNameFont,
SharedPlanetGraphics &  planetGraphics 
)

Draw the Planet.

Parameters:
core The StelCore object.
renderer Renderer used for drawing.
maxMagLabels Maximum visual magnitude to draw the label at.
planetNameFont Font used to draw the planet label.
planetGraphics Graphics shared among planets.
void Planet::draw3dModel ( StelCore *  core,
class StelRenderer *  renderer,
SharedPlanetGraphics &  planetGraphics,
StelProjector::ModelViewTranformP  transfo,
float  screenSz 
) [protected]

Draw the 3d model.

Call the proper functions if there are rings etc. .

Parameters:
core The StelCore object.
renderer Renderer used for drawing.
planetGraphics Graphics resources shared between planets, e.g. planet lighting shader.
transfo Modelview transform.
screenSz Screen size.
void Planet::drawSphere ( class StelRenderer *  renderer,
StelProjectorP  projector,
const struct StelLight *  light,
SharedPlanetGraphics &  planetGraphics,
float  screenSz 
) [protected]

Draw the 3D sphere.

Parameters:
renderer Renderer to draw with.
projector Projector to project vertices.
light If NULL, lighting is not used. Otherwise the sphere is either generated with lighting (no shaders), or lit in shaders (if GLSL is supported).
planetGraphics To render the planet using a shader on the GPU if possible.
screenSz Screen size.
void Planet::drawUnlitSphere ( class StelRenderer *  renderer,
StelProjectorP  projector 
) [protected]

Draw the unlit sphere model.

Used either when lighting is disabled or when it is done in shaders.

Called by drawSphere.

Parameters:
renderer Renderer to draw with.
projector Projector to project the vertices.
virtual double Planet::getAngularSize ( const StelCore *  core  )  const [virtual]

Return the angular radius of a circle containing the object as seen from the observer with the circle center assumed to be at getJ2000EquatorialPos().

Returns:
radius in degree. This value is the apparent angular size of the object, and is independent of the current FOV.

Implements StelObject.

virtual double Planet::getCloseViewFov ( const StelCore *   )  const [virtual]

Return the best FOV in degree to use for a close view of the object.

virtual QString Planet::getInfoString ( const StelCore *  core,
const InfoStringGroup &  flags 
) const [virtual]

Get a string with data about the Planet.

Planets support the following InfoStringGroup flags:

  • Magnitude
  • RaDec
  • AltAzi
  • Distance
  • Size
  • PlainText
