Systems and methods for generating virtual reality (VR) file(s) for complex virtual environments

A method for generating virtual reality (VR) file(s) for facilitating interactive displays of a complex virtual environment, the method comprising:

• providing a three-dimensional (3D) model of the complex environment, the 3D model comprising data defining elements represented in the complex environment;
• and
• analyzing the data of the 3D model to generate VR file(s) including an octree file, the octree file comprising data defining an octree of spatially partitioned cells, each cell of the octree containing one or more elements of the complex environment, the octree file being generated by:
• filtering the data of the 3D model to identify dynamic tessellation elements and non-dynamic tessellation elements;
• generating a plurality of triangles representing the identified non-dynamic tessellation elements;
• and
• defining cells of the octree by spatially partitioning the identified dynamic tessellation elements and triangles representing the non-dynamic tessellation elements.
