MeshPromo Posted February 5, 2020 Share Posted February 5, 2020 Definition: A fourth dimension is a place we can travel to by going in a direction perpendicular to the third dimension. 4D Facts: 1. We should able to go through an infinite number of 4th-dimensional directions. 2. When passing through the 4th dimension, the world shouldn't change, it would just be seen by different perspectives. In simple terms what we gonna do is a 2D projection of a 3D slice of a 4D object. Even though the 3d dimension has X Y Z infinite directions, in SL it is 256mx256m4096m per each sim. In the same way, we can also limit the W direction as lesser as we want as most of the 4d games have only a few 4th-dimensional directions. That gives the solution for the 1st fact. There are already multi-scene skyboxes and someone could say it is the 4th-dimensional navigation by changing the scenes, but it violates the 2nd fact as the world is changing that way. Unless LL changes the SL sim structure by adding W axis in addition to XYZ, only we can do is fake the W axis just as how we fake the 3d view by adding 2d texture as the environment of a 3d skybox. The easiest way is making linkseted objects and use the alpha texture to make the different dimensions invisible, but that also not the real 4d. As the groups of 2d triangle face made the SL 3d meshes, we should make the 4th dimension by making groups of 3d tetrahedrons. Then we texture each tetrahedron faces using 3DsMax's viewport canvas (or anything similar in other software) and make different maps to get different object shapes. Use the alpha layers to hide the extra tetrahedron linkset groups of different scenes using a HUD script. It is impossible to make very complex objects in SL using groups of tetrahedron due to the limits of SL such as triangle limits, land impact limits and the lag. But we can make boxed object such as in minecraft., besides it has 4th dimension called a hypercube. I wish someone fluent in Einstein's theories of special and general relativity plus SL mesh creation, would suggest a better solution for this concept. (English is my 3rd language, but I hope this note would be clear enough for someone interested in this concept to add more wisdom). 1 1 Link to comment Share on other sites More sharing options...
