demeter::Terrain Class Reference

This class represents a single, contiguous chunk of terrain and is the primary public interface to Demeter. Most applications will create a single instance of this class to represent the terrain in the application, but multiple instances could be used to create separate islands or to stitch together a very large world comprised of multiple terrains.

Public Member Functions
	Terrain (char szElevationsFilename, char szTextureFilename, char *szDetailTextureFilename, float vertexSpacing, float elevationScale, int maxNumTriangles, bool bUseBorders)
	Constructs a new terrain from raw grayscale data. This constructor is only used by the terrain compiler and should generally not be used by applications. Applications should use the constructor that takes map files (map files are generated by the terrain compiler.).
	Terrain (char *szCompiledMapFilename, int maxNumTriangles, bool bUseBorders=false, float offsetX=0.0f, float offsetY=0.0f)
	Constructs a new terrain from a compiled map file. Map files are created by the terrain compiler and they can be distributed with your application.
	Terrain (char szURL, char szCompiledMapFilename, int maxNumTriangles, bool bUseBorders=false)
	Constructs a new terrain by downloading a compiled map file from a remote HTTP server. Map files are created by the terrain compiler. The URL should be a well formed address with the protocol explicitly listed (for example, "http://www.terrainengine.com") The compiled map file AND the texture and detail texture files that are referenced by the compiled map file should be available from the same URL.
	~Terrain ()
	Destructor.
int	Tessellate ()
	Based on the current viewing parameters, this method breaks the terrain down into a visually optimum set of triangles that can be rendered. Normally, an application will never call this method directly, but will instead call the method ModelViewMatrixChanged() to allow Demeter to take care of this automatically.
void	Render ()
	Renders the terrain to the current OpenGL surface. Applications should always call ModelViewMatrixChanged() at least once prior to calling Render(), so that Demeter will have a chance to tessellate the terrain.
void	SetDetailThreshold (float threshold)
	Sets the "detail theshold", which controls how much Demeter simplifies the terrain. Higher thresholds will increase performance but make the terrain look worse, while lower thresholds will reduce performance and increase visual quality. Extremely high thresholds can cause significant visual artifacts and make the terrain look very strange.
float	GetDetailThreshold ()
	Returns the "detail threshold", which controls how much Demeter simplifies the terrain. Higher thresholds will increase performance but make the terrain look worse, while lower thresholds will reduce performance and increase visual quality. Extremely high thresholds can cause significant visual artifacts and make the terrain look very strange.
void	SetMaximumVisibleBlockSize (int stride)
	Sets the maximum size of blocks that can be simplified when the terrain is tessellated. The parameter stride specifies the number of vertices along one edge of the block (blocks are always square.) This parameter can be used by applications that allow much of the terrain to be visible from above, such as flight simulators, to prevent oversimplification of terrain in the distance. Setting this value too low will adversely affect performance.
int	GetWidthVertices ()
	Returns the width of the terrain in vertices (this is the count of vertices along the world's x-axis.).
int	GetHeightVertices ()
	Returns the height of the terrain in vertices (this is the count of vertices along the world's y-axis.).
float	GetWidth () const
	Returns the width of the terrain in real units (this is the length of the terrain along the world's x-axis.).
float	GetHeight () const
	Returns the height of the terrain in real units (this is the length of the terrain along the world's y-axis.).
float	GetVertexSpacing ()
	Returns the number of real units between vertices in the terrain's mesh.
float	GetElevation (float x, float y)
	Returns the elevation (z-coordinate) in real units of the specified point on the terrain.
float	GetElevation (int index)
	Returns the elevation (z-coordinate) in real units of the specified terrain vertex.
void	GetNormal (float x, float y, float &normalX, float &normalY, float &normalZ)
	Returns the surface normal of the terrain at the specified point.
float	GetMaxElevation () const
	Returns the elevation (z-coordinate) in real units of the highest point on the terrain.
float	GetVertexElevation (int index) const
	Returns the elevation (z-coordinate) in real units of the specified vertex on the terrain.
void	SetVertexElevation (int index, float newElevation)
	Sets the elevation (z-coordinate) in real units of the specified vertex on the terrain.
bool	Write (char *szCompiledMapFilename)
	Writes the current terrain to disk as a compiled map file. This method is used by the terrain compiler, but could also be used by applications as a way to persist the terrain's current state.
int	GetNumberOfVertices ()
	Returns the total number of vertices in the terrain's mesh.
int	GetTextureTileWidth ()
	Returns the width (in vertices) of the terrain's texture tiles.
int	GetTextureTileHeight ()
	Returns the height (in vertices) of the terrain's texture tiles.
int	GetNumberOfTextureTilesWidth ()
	Returns the number of texture tiles along the terrain's x-axis.
int	GetNumberOfTextureTilesHeight ()
	Returns the number of texture tiles along the terrain's y-axis.
GLuint	GetTerrainTile (int index)
	Returns the OpenGL texture number (which can be used in calls to glBindTexture()) of the specified tile. This method could be used by applications that allow some form of terrain "editing" by the user, etc. where it is necessary to show the user some or all of the tiles on the map.
bool	SetTexture (char *szFilename, bool bUseBorders)
	Applies the specified graphics image as a texture to the terrain. This is done by breaking the specified image up into smaller textures of 256x256 called "tiles" and mapping these contiguously onto the terrain's surface. The parameter bUseBorders specified whether or not the texture border OpenGL extensions should be used when creating the tiles. Textures are automatically applied when loading compiled map files, so use of this method is strictly optional.
bool	SetCommonTexture (char *szFilename)
	Uses the specified graphics file to apply a "common" texture to the entire surface of the terrain. A common texture is repeated across the entire terrain and is blended with the terrain's normal texture (if blending is supported by the user's hardware - which covers almost all OpenGL cards.) This is used to provide a "detailed" texture to give the ground some definition when the camera is close to the ground.
void	SetCommonTextureRepeats (float commonTextureRepeats)
	Sets the number of times that the "common" texture (as set by a call to SetCommonTexture()) is to repeated within each texture tile.
float	GetCommonTextureRepeats ()
	Returns the number of times that the "common" texture (as set by a call to SetCommonTexture()) is to repeated within each texture tile.
void	SetFluidElevation (float elevation)
	Not yet well implemented. Fluid support will be available soon.
bool	SetFluidTexture (char *szFilename)
	Not yet well implemented. Fluid support will be available soon.
void	Animate ()
	Not yet well implemented. Animation support will be available soon.
int	ModelViewMatrixChanged ()
	Notifies Demeter that OpenGL's modelview matrix has been modified, allowing Demeter to tessellate the terrain based on the new modelview matrix. It is IMPERATIVE that his method be called every time the modelview matrix is changed, even if this is in every single rendering cycle of the application.
bool	CubeInFrustum (float x, float y, float z, float size)
	Returns whether or not the specified cube is inside of the viewing frustum (as defined at the previous call to ModelViewMatrixChanged()).
bool	IsMultiTextureSupported ()
	Indicates whether or not OpenGL multitexture extensions are available from the OpenGL driver that this terrain instance is currently rendering against (as determined at the time the terrain instance was first constructed.).
void	DisableTextures ()
	A convenience method that sets the current OpenGL state to untextured. Calling this method disables texture state immediately; it has no effect on the terrain itself (which will reenable textures the next time it is rendered.) This is only a convenience method that allows external callers to have easy access to OpenGL multitexture extensions. There is rarely a good reason for applications to call this method.
void	EnableTextures ()
	A convenience method that sets the current OpenGL state to textured. Calling this method enables texture state immediately; it has no effect on the terrain itself (which will reenable textures the next time it is rendered.) This is only a convenience method that allows external callers to have easy access to OpenGL multitexture extensions. There is rarely a good reason for applications to call this method.
