A sparse voxel octree (SVO) is a 3D computer graphics rendering technique using a raycasting or sometimes a ray tracing approach into an octree data representation. The technique generally relies on generating and processing the hull of points (sparse voxels) which are visible, or may be visible, given the resolution and size of the screen. [1]

This repository contains templates and functions which implement common measures of Social Value Orientation in oTree. The two measures currently implemented are the Nine-Item Triple Dominance measure (Van Lange, Otten & Joireman, 1997) and the Slider Measure (Murphy, Ackermann & Handgraaf, 2011).

Sparse Voxel Octree (SVO) implementation in Rust based on 3D Flight Navigation Using Sparse Voxel Octrees with integration for the Bevy engine under the bevy feature. This crate contains only the SVO data structure with a builder and an algorithm to voxelize meshes from Bevy.

这里我们主要谈谈SVOGI和VXGI，它们的主要区别在于最终存储的数据结构不同，SVO需要使用八叉树来管理大量的Voxel纹理检索复杂。 而VXGI使用Mipmap来管理不同深度下的的GI信息。

没接触过体渲染的同学可能会对SVO有点陌生，SVO的全称是sparse voxel octree，也就是稀疏体素八叉树. 如果写过RayMarching或者MarchingCube之类算法的同学，应该都知道我们通常把空间的数据按照3D坐标存储到贴图或数组中， 但是如果空间很大的话，占用的内存就会非常 ...

SVO简介. Voxelization. 传统的mesh都表示成以三角形和四边形为单位的图元。而在SVO里，图元是更为简单和离散的voxel。每个voxel有其中心位置、大小等信息，但不需要考虑相互之间的拓扑关系。各种求交计算也变得简单了。从mesh转成voxel表达的过程就称为voxelization。

A sparse voxel octree is a data structure which stores voxels in a tree with a branching factor of 8, with its branches being potentially absent. Missing branches typically represent empty volumes where no voxels exist.

2020年12月16日 · SVO's usually store the information of each voxel inside a struct. Those structs are then connected together either with pointers (called an explicit svo) or by storing the voxel structs inside an array and then store the indices to their children (implicit SVO).
