Detailed Description

Class ParamDimension.

Description:

This class (along with ParamDimension) describes the dimension of a parameter. This dimension can be considered a unit of measure. It describes the parameter's type and order of magnitude.

The dimension type and possibly the dimension scale (if the type is custom) are used to determine a scale factor for the parameter. When a controller is drawing a function curve, it only needs to use the Convert() function - the scale factor is rolled into the single 'vzoom' parameter passed to Animatable::PaintFCurves(). So, for a controller to plot a value 'val' at time t it would do the following:

int x = TimeToScreen(t,tzoom,tscroll);

int y = ValueToScreen(dim->Convert(val),rect.h()-1,vzoom,vscroll);

virtual ~ParamDimensionBase ( )

Member Function Documentation

DimensionType()

virtual DimType DimensionType ( )

pure virtual

Remarks

Returns the dimension type of the parameter. See Dimension Types

Convert() [1/2]

virtual float Convert ( float  value )

pure virtual

Remarks

When a controller needs to display the parameter values (for example in the function curve editor) it converts the value using this method.

Parameters

value

The value to convert.

Returns

The converted value.

UnConvert() [1/2]

virtual float UnConvert ( float  value )

pure virtual

Remarks

This method is used to un-convert from a displayed value to the actual value

Parameters

value

The value to un-convert.

Returns

The un-converted value.

Convert() [2/2]

CoreExport int Convert

(

int

value

)

Converts integer values based on the parameter dimensions.

In order to ensure that integers larger than 2 ^ 24 - 1 are converted properly, use this method instead of ParamDimensionBase::Convert(float value)

Remarks

This method converts the integer parameter value to a float value and calls Convert on that float value. If the return value from that call is unchanged, the original integer value is returned, otherwise the returned float value cast to an integer is returned. This is to handle the case where a large integer value (>2^24 - 1) that cannot be represented as a float value is passed. This would result in a value change even though the Convert implementation itself did not change the value.

Parameters

value

The value to convert.

Returns

The converted value.

UnConvert() [2/2]

CoreExport int UnConvert

(

int

value

)

Unconverts integer values based on the parameter dimensions.

In order to ensure that integers larger than 2 ^ 24 - 1 are converted properly, use this method instead of ParamDimensionBase::UnConvert(float value)

Remarks

This method converts the integer parameter value to a float value and calls UnConvert on that float value. If the return value from that call is unchanged, the original integer value is returned, otherwise the returned float value cast to an integer is returned. This is to handle the case where a large integer value (>2^24 - 1) that cannot be represented as a float value is passed. This would result in a value change even though the UnConvert implementation itself did not change the value.

Parameters

value

The value to convert.

Returns

The converted value.
