Setting up a custom environment in Spatial<\/p>\n

<\/p>\n

This tutorial follows the requirements described on the Spatial.io web site here (https:\/\/support.spatial.io\/hc\/en-us\/articles\/360058728892-Custom-Environments-<\/a>) and here (https:\/\/support.spatial.io\/hc\/en-us\/articles\/360042195672<\/a>) but it describes more in details the setting up of the 3D model.<\/p>\n

For this example I started from Rhino. The 3D is made with Grasshopper. The definition is explained here. It\u2019s a wooden structure, shape is obtain from a simulation computed with Kangaroo. As it drawn from Brep and Nurbs, the danger would be to have too much polygons for a real time experience.<\/p>\n

<\/p>\n

After a bit of cleaning the object is selected to be exported<\/p>\n

<\/p>\n

<\/p>\n

<\/p>\n

Sometimes Rhino smoothes the polygons; tests have to be made. Choose the lowest level to export.<\/p>\n

<\/p>\n

It polygons are smoothed, it’s better to use OBJ export.<\/p>\n

<\/p>\n

<\/p>\n

Using QuadMesh may improve the RealTime experience as the geometry will be Quad only. Real Time Engines prefer Quad only meshes!<\/p>\n

<\/p>\n

If the model is imported as this in Spatial, There will be no light. It results a very poor looking 3D.<\/p>\n

<\/p>\n

To avoid that, we will compute the light and bake it into the 3D. In other words, the light will be drawn as a texture. It will improve the look of our model and make it more realistic.<\/p>\n

The baking process can be tricky or a very long process. In Blender for instance, objects have to be UV prepared one by one and then baked. To ease the process we will use Simlab Composer.<\/p>\n

SimlLab is a fantastic tool to prepare Virtual Experiences. It\u2019s one of the best platform to jump into the virtual world or to prepare models\u2026for Spatial\u2026! https:\/\/www.simlab-soft.com\/3d-products\/simlab-composer-main.aspx<\/a><\/p>\n

We prepare a ground<\/p>\n

<\/p>\n

We import our geometry<\/p>\n

<\/p>\n

Press F4 for real time rendering and adjust the light ambiance<\/p>\n
