TGorillaNormalMapMaterialSource

The normal map material extends the default shader by normal mapping feature to simulate more detailled meshes.

Remarks

In 3D computer graphics, normal mapping (or Dot3 bump mapping) is a technique used for faking the lighting of bumps and dents – an implementation of bump mapping. It is used to add details without using more polygons. A common use of this technique is to greatly enhance the appearance and details of a low polygon model by generating a normal map from a high polygon model or height map. Normal maps are commonly stored as regular RGB images where the RGB components correspond to the X, Y, and Z coordinates, respectively, of the surface normal.

published NormalMap : TBitmap
Get or set a normal map texture for bumpmapping effect. This is only a weak reference to the second entry in the texture pool (Bitmaps).
published NormalTexture : TBitmap
read GetNormalTexture
write SetNormalTexture
published DisplacementMap : TBitmap
Get or set a displacement map to manipulate vertices in vertex shader. This is another method besides normal-mapping to create a more detailled mesh.
published DisplacementX : Single
Get or set the displacement vector X component.
read GetDisplacementPart
write SetDisplacementPart
published DisplacementY : Single
Get or set the displacement vector Y component.
read GetDisplacementPart
write SetDisplacementPart
published DisplacementZ : Single
Get or set the displacement vector Z component.
read GetDisplacementPart
write SetDisplacementPart
published DisplacementDir : Single
Get or set the displacement vector W component. This will be used as direction for displacement mapping (-1 will displace to the inner, while +1 will extend the model).
