## Member Data Documentation

u8 irr::video::SMaterialLayer::AnisotropicFilter

Is anisotropic filtering enabled? Default: 0, disabled.

In Irrlicht 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.

bool irr::video::SMaterialLayer::BilinearFilter

Is bilinear filtering enabled? Default: true.

Definition at line 192 of file SMaterialLayer.h.

Referenced by irr::video::SOverrideMaterial::apply(), irr::video::SMaterial::getFlag(), operator!=(), and operator=().

s8 irr::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.

ITexture* irr::video::SMaterialLayer::Texture

Texture.

u8 irr::video::SMaterialLayer::TextureWrapU

Texture Clamp Mode.

Values are taken from E_TEXTURE_CLAMP.

bool irr::video::SMaterialLayer::TrilinearFilter

Is trilinear filtering enabled? Default: false.

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