2010年 NVidia 就曾发表研究[8],展示如何高效地使用 GPU 去光线追踪以稀疏体素八叉树(sparse voxel octree, SVO)表示的场景。在该研究中,每体素还存储了颜色及法綫的压缩数据。 My current shader tests an AABBox intersection test against each voxel as it traverses the tree and when it finds the final leaf voxel along a path it outputs a flat color based on the shader attachments. However, this means I can only have one color for an entire voxel. I have no control over individual faces within the voxel. easily define the typing of voxel data. You can also customize pre and post-rendering tasks, various early tests, hints, and flag for preferred behaviors (e.g., priority strategy in strict-realtime). The basic Gigavoxels relies on octree dynamic partitionning of space, which nodes corresponds to voxel bricks - if space is not empty there.

The voxel data is added to an octree (a data tree with internal nodes containing eight children) that makes the reflection render pass very efficient, because all complex lighting data is pre-calculated for each voxel. The efficiency of the look up into this data enables the real-time ray tracing experience to run at resolutions up to 4K.No Sparse Voxel Octree is used, this is because I concluded from my early experiments that traversing the tree takes a huge toll on performance probably because the divergent code paths and incoherent memory accesses are not very GPU friendly. ... This especially counts twice for compute shaders, as AMD finally supports them in stable driver ...It's precisely what he said, while the basic premise is feasible (and demonstrated in your link and with games like Minecraft and the various sparse voxel octree demos on youtube) the issue is that dynamic lighting for raytracing and animation of high resolution voxel meshes is prohibitively expensive.

Global illumination (GI), or indirect illumination, is a group of algorithms used in 3D computer graphics that are meant to add more realistic lighting to 3D scenes. Such algorithms take into account not only the light that comes directly from a light source (direct illumination), but also subsequent cases in which light rays from the same source are reflected by other surfaces in the scene ... Jun 23, 2013 · Not really Voxel Cone Tracing – just rasterizes the world scene into a 3D Texture and traces that for illumination – it’s like a raw dump of the voxels with a standard octree structure.. HALO is simply a standard octree with 8 nodes – with some extra data – each node has a link to it’s next axis siblings parent. For rendering the octree is then written to a texture and processed by vertex and pixel shader to display the actual voxel directly on the GPU. Although I guess I could walk the octree on the CPU, and instead of building the texture, draw the individual voxels through instancing although probably a bit slower. Voxel Cone Tracing (VCT) will be explored, identifying the positive and negative aspects of each algorithm. A new approach to the voxel cone tracing using interleaved sampling and voxel mips will be examined and compare to the original voxel cone tracing technique to highlight improvements that has been made.

Sparse voxel octree global illumination (SVOGI), also known as voxel GI, is a global illumination solution based on voxel ray tracing. It does not require prebaking or manual setup of bounce lights or light volumes. This solution is experimental and may be memory intensive. Voxel GI provides the following effects:I've never written a compute shader before and am basically just learning by a few references and the incredibly sparse Unity documentation. So I'm quite probably doing things terribly wrong. I'm creating a sparse voxel octree on the GPU to run marching cubes against: @thokra The example i gave is very simplified, actually the shader is building a sparse voxel octree, the vertex count tells how much voxels are left to insert in the tree, because multiple voxels can try to subdivide the same octree node only one is doing the subdivision, the other voxels are set on a "wait list" which is executed in a later pass to avoid waiting in one pass – FamZ Jan 9 ...

A Voxel is -NOT- simply a pixel with depth (that's just a layman's definition). It is a 3 dimensional position in space with some data associated with it, the combined result of which we use to create visual representations of objects. This is a good post, but I'd argue some on this paragraph. Sparse voxel octrees are used for value storage. And some voxel inherent challenges like the "thin wall" problem. There's a bunch of videos on my YouTube channel showing the progress over time. In theory this approach could be applied to 3rd party graphics engines, although there's quite a few caveats, mainly around how the shaders would need to be restricted.
