Member Data Documentation

SColor irr::video::SMaterial::AmbientColor

How much ambient light (a global light) is reflected by this material.

The default is full white, meaning objects are completely globally illuminated. Reduce this if you want to see diffuse or specular light effects.

Definition at line 306 of file SMaterial.h.

Referenced by operator!=(), and operator=().

u8 irr::video::SMaterial::AntiAliasing

Sets the antialiasing mode.

Values are chosen from E_ANTI_ALIASING_MODE. Default is EAAM_SIMPLE|EAAM_LINE_SMOOTH, i.e. simple multi-sample anti-aliasing and lime smoothing is enabled.

Definition at line 372 of file SMaterial.h.

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

bool irr::video::SMaterial::BackfaceCulling

Is backface culling enabled? Default: true.

Definition at line 425 of file SMaterial.h.

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

E_BLEND_OPERATION irr::video::SMaterial::BlendOperation

Store the blend operation of choice.

Values to be chosen from E_BLEND_OPERATION. The actual way to use this value is not yet determined, so ignore it for now.

Definition at line 392 of file SMaterial.h.

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

u8 irr::video::SMaterial::ColorMask

Defines the enabled color planes.

Values are defined as or'ed values of the E_COLOR_PLANE enum. Only enabled color planes will be rendered to the current render target. Typical use is to disable all colors when rendering only to depth or stencil buffer, or using Red and Green for Stereo rendering.

Definition at line 379 of file SMaterial.h.

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

u8 irr::video::SMaterial::ColorMaterial

Defines the interpretation of vertex color in the lighting equation.

Values should be chosen from E_COLOR_MATERIAL. When lighting is enabled, vertex color can be used instead of the material values for light modulation. This allows to easily change e.g. the diffuse light behavior of each face. The default, ECM_DIFFUSE, will result in a very similar rendering as with lighting turned off, just with light shading.

SColor irr::video::SMaterial::DiffuseColor

E_POLYGON_OFFSET irr::video::SMaterial::PolygonOffsetDirection

Flag defining the direction the polygon offset is applied to.

Can be to front or to back, specififed by values from E_POLYGON_OFFSET.

Definition at line 401 of file SMaterial.h.

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

u8 irr::video::SMaterial::PolygonOffsetFactor

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

f32 irr::video::SMaterial::Shininess

Value affecting the size of specular highlights.

A value of 20 is common. If set to 0, no specular highlights are being used. To activate, simply set the shininess of a material to a value in the range [0.5;128]:

        sceneNode->getMaterial(0).Shininess = 20.0f;

You can change the color of the highlights using

        sceneNode->getMaterial(0).SpecularColor.set(255,255,255,255);

The specular color of the dynamic lights (SLight::SpecularColor) will influence the the highlight color too, but they are set to a useful value by default when creating the light scene node. Here is a simple example on how to use specular highlights:

        // load and display mesh
        scene::IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode(
        smgr->getMesh("data/faerie.md2"));
        node->setMaterialTexture(0, driver->getTexture("data/Faerie2.pcx")); // set diffuse texture
        node->setMaterialFlag(video::EMF_LIGHTING, true); // enable dynamic lighting
        node->getMaterial(0).Shininess = 20.0f; // set size of specular highlights

        // add white light
        scene::ILightSceneNode* light = smgr->addLightSceneNode(0,
            core::vector3df(5,5,5), video::SColorf(1.0f, 1.0f, 1.0f));

Definition at line 350 of file SMaterial.h.
