Bump-mapping

Bump Mapping is a technique used in 3D visualization programs to improve the level of detail of objects without increasing their geometric complexity. The trick is that the required information is stored in a texture which is used to draw shadows on a surface. The Bump-Mapping technique is therefore only an illusion (although effective) which simulates a surface inequality which is not present in the geometry of the model. It improves image quality and realism without significantly affecting the time taken to render it. In addition, the field of application is not limited to colors. Bump mapping is already playing a major role in projects of the entertainment industry, as visual quality can be improved significantly without noticeably affecting performance.

Categories

The categories in EEP constitute the set of classes to carry out the construction of a railway project. These classes contain objects (models) distributed differently in 2D and 3D windows.

In the 2D window, the categories correspond to the name of each editor, namely:

  • The railway tracks editor,
  • The routes editor,
  • The tram tracks editor,
  • The animated characters editor,
  • The structures editor,
  • The landscape editor,
  • The surface editor,
  • The signaling system editor,
  • The goods/merchandise editor,
  • The other tracks editor,
  • The predefined routes editor.

In the 3D window, the categories are found in the drop-down list of the first tab Inserting and placing models in the control window :

Each category includes several sub-categories in which the models belonging to a particular type are placed.

Example : in the Structures category, you will find the sub-categories City, Countryside, Commerce and industry, Transport, Equipment to name a few.

Name Lua

Lua is a scripting language for performing certain tasks in an EEP project. For example, you can find the name of a train or even turn on the lights of a vehicle, act on the signaling, etc…

The Lua name of a model that is always unique. This can not be changed. This is a name internal to EEP to identify the object in order to interact with some of its properties inside a Lua script.

Conversely, you can name a lua function whatever you want. For example this function fncCreation_Car () to create a hash string :

				
					function fncCreation_Car()
	for i = 48,  57 do table.insert(g_tblCar, string.char(i)) end
	for i = 65,  90 do table.insert(g_tblCar, string.char(i)) end
	for i = 97, 122 do table.insert(g_tblCar, string.char(i)) end
end

SSAO Mode

SSAO mode manages ambient occlusion. But what exactly is ambient occlusion?

Ambient Occlusion is an algorithm used in 3D modeling, aimed at improving the realism of a rendering.

It darkens areas that are naturally difficult to access to light. This has the effect of revealing the relief of the objects, where the latter, without the application of this technique (or another more elaborate technique), would appear entirely flat. As this method is close to physically correct solutions like global illumination, it is generally pleasing to the eyes and gives a natural impression. The missing point in relation to global illumination is that ambient occlusion is not able to represent indirect reflections, only the occlusion of irradiating flows. Thanks to this simplification, it is more convenient to calculate. (Wikipedia sources).
