 +  - In order for the proportions to correspond to reality when displaying the textures, measurements are required for the size of the texture section. This [[https://vrdoro.com/store/~/textures/ccHJvZHVjdElkPTMzMDAmc2VuZGVySWQ9MzA5NDg-c|parquet example]] shows a section measuring 5997 mm x 5997 mm. 
 +  - To visualise an area that is larger than the area represented in the texture, the texture is repeated. To ensure that no seam is visible at this point, a seamless texture is required.

-==== Diffuse map ====+==== Diffuse Map ====
  
-The diffuse map is the basic texture and is also known as the colour map, as it is used to define the colours of the model.+The diffuse map is the basic texture and is also referred to as a colour map, as it is used to define the colours of the model.
  
-==== Normal map ==== +==== Normal Map ==== 
-A normal map influences the normal vector. In geometry, a normal vector is a vector that is orthogonal (i.e. at right angles, perpendicular) to a straight line, curve, plane or (curved) surface. A straight line with this vector as the direction vector is called a normal vector (en: normal). (More about this: [[https://de.wikipedia.org/wiki/Normalenvektor|Wikipedia]])+A normal map influences the normal vector. In geometry, a normal vector is a vector that is orthogonal (i.e. perpendicular) to a straight line, curve, plane or (curved) surface. A straight line with this vector as its direction vector is called a normal vector (en: normal). (More on this: [[https://de.wikipedia.org/wiki/Normalenvektor|Wikipedia]])
  
 The normal vector influences the direction of light reflection. The normal map can therefore be used to influence light reflection. The normal vector influences the direction of light reflection. The normal map can therefore be used to influence light reflection.
  
-When viewing a texture, we also show an additional **normal quality indicator as a blue-purple circle below the texture object.** below the texture object. The less movement there is in the bright dot, the smaller the deviation from the vertical normal for this texture.+When viewing a texture, we also display a **normal quality indicator as a blue-purple circle below the texture object**. The more stationary the bright spot is, the smaller the deviation from the perpendicular normal for this texture.

-**What does a rotating dot on the normal quality indicator mean?** If the bright dot rotates here, then a reflection is influenced by the normal map in such a way that a rotation of the surface around the vertical axis for a light reflection causes a shift in the position of the reflection. This means that if the texture is to be used for a floor covering, it makes a difference to the reflection if the surface is rotated by 180 degrees. The reflection of a sun on this reflective texture is then displayed offset, which can lead to undesirable effects.+**What does a rotating point on the normal quality indicator mean?** If the bright point rotates here, the reflection is influenced by the normal map in such a way that a rotation of the surface around the vertical axis causes a positional shift of the reflection. This means that if the texture is to be used for flooring, rotating the surface by 180 degrees will make a difference in terms of reflection. The reflection of the sun on this reflective texture will then be offset, which can lead to undesirable effects.
  
-For straight surfaces such as floors or walls, only use textures where the normal quality indicator shows a point that is as stable as possible.+For flat surfaces such as floors or walls, only textures should be used where the normal quality indicator shows as stable a point as possible.
