Constructor & Destructor Documentation

SMaterialLayer()

nirt::video::SMaterialLayer::SMaterialLayer ( const SMaterialLayer &  other )

inline

Copy constructor.

Parameters

other

Material layer to copy from.

Member Function Documentation

getTextureMatrix() [1/2]

core::matrix4 & nirt::video::SMaterialLayer::getTextureMatrix ( )

inline

Gets the texture transformation matrix.

Returns

Texture matrix of this layer.

getTextureMatrix() [2/2]

const core::matrix4 & nirt::video::SMaterialLayer::getTextureMatrix ( ) const

inline

Gets the immutable texture transformation matrix.

Returns

Texture matrix of this layer.

operator!=()

bool nirt::video::SMaterialLayer::operator!= ( const SMaterialLayer &  b ) const

inline

Inequality operator.

Parameters

b	Layer to compare to.

Returns

True if layers are different, else false.

operator=()

SMaterialLayer & nirt::video::SMaterialLayer::operator= ( const SMaterialLayer &  other )

inline

Assignment operator.

Parameters

other

Material layer to copy from.

Returns

This material layer, updated.

operator==()

bool nirt::video::SMaterialLayer::operator== ( const SMaterialLayer &  b ) const

inline

Equality operator.

Parameters

b	Layer to compare to.

Returns

True if layers are equal, else false.

setTextureMatrix()

void nirt::video::SMaterialLayer::setTextureMatrix ( const core::matrix4 &  mat )

inline

Sets the texture transformation matrix to mat.

NOTE: Pipelines can ignore this matrix when the texture is 0.

Parameters

mat	New texture matrix for this layer.

Member Data Documentation

AnisotropicFilter

u8 nirt::video::SMaterialLayer::AnisotropicFilter

Is anisotropic filtering enabled? Default: 0, disabled.

In Nirtcpp you can use anisotropic texture filtering in conjunction with bilinear or trilinear texture filtering to improve rendering results. Primitives will look less blurry with this flag switched on. The number gives the maximal anisotropy degree, and is often in the range 2-16. Value 1 is equivalent to 0, but should be avoided.

LODBias

s8 nirt::video::SMaterialLayer::LODBias

Bias for the mipmap choosing decision.

This value can make the textures more or less blurry than with the default value of 0. The value (divided by 8.f) is added to the mipmap level chosen initially, and thus takes a smaller mipmap for a region if the value is positive.

TextureWrapU

u8 nirt::video::SMaterialLayer::TextureWrapU

Texture Clamp Mode.

Values are taken from E_TEXTURE_CLAMP.

TrilinearFilter

bool nirt::video::SMaterialLayer::TrilinearFilter

Is trilinear filtering enabled? Default: false.

If the trilinear filter flag is enabled, the bilinear filtering flag is ignored.
