Detailed Description

Deal with the OpenGL library to render game's objects. This class shouldn't play with SDL functions but OpenGL

Member Function Documentation

void Renderer::_DisplayMapGrid const Map pcmap  )  [private]

Draw the dotted grid. This method uses OpenGL display list inside.

Definition at line 1344 of file renderer.cpp.

References _uiCityWidth, _uiGridList, boolHeightChange, and Map::GetLinearHeight().

Referenced by Display().

void Renderer::_DisplayTerrain  )  const [private]

Draw the terrain as an _unique_ TRIANGLE_STRIP which is known as the fastest primitive in OpenGL. It starts at the north-west and when it reaches the north-east map edge, it starts drawing from the north-east to the north-west eadge. Finally the algorithm draws from the north to the south.

Definition at line 1026 of file renderer.cpp.

References _uiCityWidth, _uiTerrainList, _uiTerrainTex, boolHeightChange, Map::GetSquareHeight(), and GlobalVar::gpMapMgr.

Referenced by Display().

void Renderer::_PrepareView  )  const [private]

Prepare the world before drawing the entire scene

Definition at line 1470 of file renderer.cpp.

References iWinHeight.

Referenced by Display().

void Renderer::Display const Map pcMap,
const Layer pcLayer

Display the layer and the map to the back buffer. The caller must swap the buffers to show the changes

Definition at line 574 of file renderer.cpp.

References _DisplayMapGrid(), _DisplayTerrain(), _PrepareView(), _uiCityWidth, boolHeightChange, GraphicManager::DisplayStructure(), Layer::GetLinearStructure(), and GlobalVar::gpGraphicMgr.

void Renderer::DisplayBuildPreview const uint &  uiW,
const uint &  uiL,
const GLubyte &  rcubR,
const GLubyte &  rcubG,
const GLubyte &  rcubB,

Display the specified graphic code with a bounding rectangle

Definition at line 699 of file renderer.cpp.

References GraphicManager::DisplayGC(), Map::GetSquareMaxHeight(), PropertyManager::GetWLH(), GlobalVar::gpGraphicMgr, GlobalVar::gpMapMgr, and GlobalVar::gpPropertyMgr.

void Renderer::DisplaySplash const uint &  rcuiX = 0,
const uint &  rcuiY = 0

Display the splash screen at the specified coordinates

Definition at line 525 of file renderer.cpp.

References _uiSplashTex, and Texture::Load().

void Renderer::Home  ) 

Reinit the map's position as if the game has just been launched

Definition at line 285 of file renderer.cpp.

References dDeltaX, dDeltaZ, dEyeX, dEyeY, dYRotateAngle, and fXTransDelta.

void Renderer::SetWinSize const int &  rciWidth,
const int &  rciHeight

This method _must_ be called whenever the window's size changes. It calculates the viewport and set the correct internal window's width and height

Definition at line 995 of file renderer.cpp.

References iWinHeight.

Member Data Documentation

bool Renderer::boolHeightChange

The City class use this to notify the renderer class that the height of the map has changed and the current buffered informations need to be recalculated

GLdouble Renderer::dDeltaX [private]

Contains the X value for the translation of the layer. It is used by MoveLeft() and MoveRight()

GLdouble Renderer::dDeltaZ [private]

Contains the Z value for the translation. It is used by MoveUp() and MoveDown()
