NormalMapEffect

This effect extends BasicEffect to support normal-mapping and an optional specular map. It supports texture mapping, vertex coloring, directional per-pixel lighting, and fog.

Header

#include <Effects.h>

Initialization

Construction requires a Direct3D 11 device.

std::unique_ptr<NormalMapEffect> effect;
effect = std::make_unique<NormalMapEffect>(device);

For exception safety, it is recommended you make use of the C++ RAII pattern and use a std::unique_ptr or std::shared_ptr

Interfaces

NormalMapEffect supports IEffect, IEffectMatrices, IEffectLights, and IEffectFog

Input layout

This effect requires SV_Position, NORMAL, TEXCOORD0, and TANGENT. If per-vertex colors are enabled, it also requires COLOR.

Properties

• SetDiffuseColor: Sets the diffuse color of the effect. Defaults to white (1,1,1). Alpha channel (.w component) is ignored.

• SetEmissiveColor: Sets the emissive color of the effect. Defaults to black (0,0,0).

• SetSpecularColor: Sets the specular color of the effect. Defaults to white (1,1,1).

• SetSpecularPower: Sets the specular power of the effect. Defaults to 16. Settings power to 0 can cause strange rendering artifacts.

• DisableSpecular: Disables the specular lighting for the effect. Sets the color to black (0,0,0) and power to 1.

• SetAlpha: Sets the alpha (transparency) of the effect. Defaults to 1 (fully opaque).

• SetColorAndAlpha: Sets the diffuse color of the effect and the alpha (transparency).

• SetVertexColorEnabled: Enables per-vertex color. Defaults to false. Modifying this setting requires recreating associated input layouts, and enabling it requires COLOR.

• SetTexture: Associates a texture shader resource view with the effect for the diffuse texture. Can be set to nullptr to remove a reference.

• SetNormalTexture: Associates a texture shader resource view with the effect for the normal map texture. Can be set to nullptr to remove a reference.

• SetSpecularTexture: Associates a texture shader resource view with the effect for the specular texture. Can be set to nullptr.

Remarks

This effect always performs per-pixel lighting. Calls to SetLightingEnabled(false); will generate a C++ exception, and calls to SetPerPixelLighting are ignored.

This effect always performs texturing, so if 'untextured' diffuse rendering is desired you must provide a 1x1 texture with white (1,1,1,1).
