OgreVoxelTree - Test4 - Detail

This video shows how the use of scale can be used to create more detailed areas with voxels. The scene features a small red brick shed building with some simple furniture inside. This demo only uses a small number of textures and has no lighting at this stage.

It is a bit hard to see the detail presently as there is no lighting.

Note as this is an octree, the voxels in this scene vary in size from around 2 pixels, up to about 64 pixels. The maximum voxel size is 2^23 pixels. The scene is at most 2^24 pixels in size in any dimension. So this can be used to create areas of low or high detail / at large and small scales.

This version of the software has been re-written to use a persistent mesh, as well as voxel octree optimizations. The result means slower per-voxel extraction time, but as scene complexity increases the extraction time remains fairly much the same. (Whereas the previous version became unusably slow after a few hundred voxels were added.)

This version also allows saving scenes to disk. This particular scene when saved to disk is 129KB. With this scene loaded into memory, the application uses around 450MB of RAM. The design also allows paging to be added fairly easily.
