Member Function Documentation

addAlphaCtrl()

virtual void addAlphaCtrl ( vec3  v )

inlinevirtual

Here is the call graph for this function:

addSpectrumValue()

virtual void addSpectrumValue ( real  pos, color  value  )

inlinevirtual

Add a color value to the spectrum at the given position then resort the spectrum.

Here is the call graph for this function:

clearSpectrum()

virtual void clearSpectrum ( )

inlinevirtual

Here is the call graph for this function:

copySpectrumFrom()

virtual void copySpectrumFrom ( const Spectrum *  s )

inlinevirtual

Here is the call graph for this function:

Here is the caller graph for this function:

fillColorMatrix()

virtual void fillColorMatrix ( ColorMatrix *  col, const RealMatrix *  mat, bool  useValAsAlpha = false  ) throw ( IndexException )

inlinevirtual

Interpolate the colors from the material's spectrum into `col' using the unit values in the first column of `mat'. If `mat' has two columns, multiply the resulting color's alpha channel by the second column value.

Here is the call graph for this function:

getAlpha()

virtual real getAlpha ( ) const

inlinevirtual

Reimplemented in Material.

getAlphaCtrl()

virtual vec3 getAlphaCtrl ( indexval  index ) const throw ( IndexException )

inlinevirtual

Here is the call graph for this function:

getDefaultColor()

virtual color getDefaultColor ( ) const

inlinevirtual

Reimplemented in Material.

getName()

virtual const char* getName ( ) const

inlinevirtual

Reimplemented in OgreMaterial.

Here is the caller graph for this function:

getSpectrumIndex()

virtual indexval getSpectrumIndex ( real  pos, color  value  ) const

inlinevirtual

Get the index of the spectrum value with the given position and color, returns numSpectrumValues() if not found.

Here is the call graph for this function:

getSpectrumPos()

virtual real getSpectrumPos ( indexval  index ) const throw ( IndexException )

inlinevirtual

Get the position of the spectrum value at the given index in the list.

Here is the call graph for this function:

getSpectrumValue()

virtual color getSpectrumValue ( indexval  index ) const throw ( IndexException )

inlinevirtual

Get the color of the spectrum value at the given index in the list.

Here is the call graph for this function:

interpolateColor()

virtual color interpolateColor ( real  pos ) const

inlinevirtual

Interpolate a color with the spectrum at the given position. If `pos' is less than or equal to the position of the first spectrum value, that color is returned, if greater than or equal that of the last spectrum value, that color is returned. If neither is true, there exists two values cmin and cmax such that the position of cmin is less than `pos' and that of cmax is greater. This method will then use the distance `pos' is from these other positions to interpolate between cmin and cmax.

Here is the call graph for this function:

Here is the caller graph for this function:

isLinearAlpha()

virtual bool isLinearAlpha ( ) const

inlinevirtual

Here is the call graph for this function:

numAlphaCtrls()

virtual sval numAlphaCtrls ( ) const

inlinevirtual

Here is the call graph for this function:

numSpectrumValues()

virtual sval numSpectrumValues ( ) const

inlinevirtual

Get the number of spectrum values.

Here is the call graph for this function:

removeAlphaCtrl()

virtual void removeAlphaCtrl ( indexval  index ) throw ( IndexException )

inlinevirtual

Here is the call graph for this function:

removeSpectrumValue()

virtual void removeSpectrumValue ( indexval  index ) throw ( IndexException )

inlinevirtual

Remove the spectrum value at the given index.

Here is the call graph for this function:

setAlphaCtrl()

virtual void setAlphaCtrl ( vec3  v, indexval  index  ) throw ( IndexException )

inlinevirtual

Here is the call graph for this function:

setAlphaCurve()

virtual void setAlphaCurve ( const Vec3Matrix *  pts )

inlinevirtual

Here is the call graph for this function:

setLinearAlpha()

virtual void setLinearAlpha ( bool  b )

inlinevirtual

Here is the call graph for this function:

Here is the caller graph for this function:

setSpectrumValue()

virtual void setSpectrumValue ( sval  index, real  pos, color  value  ) throw ( IndexException )

inlinevirtual

Set the spectrum value at the given list index.

Here is the call graph for this function:

updateSpectrum()

virtual void updateSpectrum ( )

inlinevirtual

Reimplemented in Material, and OgreMaterial.
