• 8-Directional Normal

  TMAC uses eight directional photommetry to derive crisp normal map of the surface. Normal map represents surface relief or bumpiness of the sample.

• Albedo

  With cross polarization it is possible to derive a map that has no perceived light and reflections. Albedo represents non-lit color of the sample ready to be lit up again in virtual space.

• Metalness

  Materials in real world fall into categories of metals and insulators. Metals tend to have more prominent specular reflection whereas insulators have less prominent reflection. Metalness describes which part of the sample is metal and which is insulator.

• Translucency

  Translucency is how light travels trough the surface. In other words it is underlighting.

• Alpha

  Many surfaces are not fully solid. They have smaller or bigger air gaps. These holes are represented in alpha map by black color and solid parts by white color.

• Roughness

  Roughness map defines what part of the object is fully shiny - like mirror - and which parts are matte. Current TMAC has sparse rapid sampling of roughness and provided roughness map is generally correct. There are limitations with super planar and perfectly flat surfaces.

• Pseudo Height

  Although relief of the surface is represented in normal map, there is no notion of depth. Height map defines distance from camera and is used to represent more severe reliefs of surfaces. TMAC does not have notion of this distance thus map is estimated from normal map and shall be considered pseudo.
