Detailed Description

template<class T>
class irr::core::dimension2d< T >

Specifies a 2 dimensional size.

Member Function Documentation

getInterpolated()

template<class T>

dimension2d< T > irr::core::dimension2d< T >::getInterpolated ( const dimension2d< T > & other, f32 d ) const

inline

Get the interpolated dimension.

Parameters

other	Other dimension to interpolate with.
d	Value between 0.0f and 1.0f.

Returns

Interpolated dimension.

getOptimalSize()

template<class T>

dimension2d< T > irr::core::dimension2d< T >::getOptimalSize ( bool requirePowerOfTwo = true, bool requireSquare = false, bool larger = true, u32 maxValue = 0 ) const

inline

Get the optimal size according to some properties.

This is a function often used for texture dimension calculations. The function returns the next larger or smaller dimension which is a power-of-two dimension (2^n,2^m) and/or square (Width=Height).

Parameters

requirePowerOfTwo	Forces the result to use only powers of two as values.
requireSquare	Makes width==height in the result
larger	Choose whether the result is larger or smaller than the current dimension. If one dimension need not be changed it is kept with any value of larger.
maxValue	Maximum texturesize. if value > 0 size is clamped to maxValue

Returns

The optimal dimension under the given constraints.
