Parallax Ground Textures

By Tony_Hilliam, December 07 2017

This week we bring you more examples of height mapping on a range of ground textures. In case you missed our earlier videos, this parallax effect is a distant relative of normal mapping, where the texture includes an additional "height" channel in addition to the usual XYZ normal information. 

The height information is used to perform simple ray-tracing on the GPU, resulting in some ultra-realistic visuals. To be entirely honest, the technique does have its limitations - you can't simply add it to every asset and expect it to benefit everything equally - but used correctly for example on our terrain system, it can add a lot to the scene.

For more information on future Trainz development be sure to keep up-to-date at http://www.trainzportal.com or see all the articles and have your say at the forums.

All content creators wanting to start to look into the technique will find some initial information on the Trainz wiki soon.
