Detailed Description

Normal Map Lighting extension sub render state implementation.

Derives from SubRenderState class.

Member Enumeration Documentation

NormalMapSpace

enum Ogre::RTShader::NormalMapLighting::NormalMapSpace

Normal map space definition.

Enumerator
NMS_OBJECT	Normal map contains normal data in object local space. This normal mapping technique has the advantages of better visualization results, lack of artifacts that comes from texture mirroring usage, it doesn't requires tangent and it also saves some instruction in the vertex shader stage. The main drawback of using this kind of normal map is that the target object must be static in terms of local space rotations and translations.
NMS_TANGENT	Normal map contains normal data in tangent space. This is the default normal mapping behavior and it requires that the target mesh will have valid tangents within its vertex data.
NMS_PARALLAX	Normal map contains normal data in parallax corrected tangent space The restrictions of NMS_TANGENT apply. Additionally the alpha channel of the normal texture is expected to contain height displacement data. This is used for parallax corrected rendering.
