Description

Big picture: Volumes need their own native datablock type, so Blender can support other use cases like rendering OpenVDB files or procedurally generating volumes.

Use cases:

  • Existing use cases (smoke modifier on mesh).
  • OpenVDB file rendering.
  • Procedurally generating volumes (part of everything nodes).

Design:

  • New Volume datablock (similar to Mesh) with an OpenVDB volume data structure with an arbitrary number of attributes.
  • Rendered by Cycles and Eevee, first as dense volume as we have now, and later with native sparse volume rendering.
  • Volume objects would have modifiers (add resolution detail, fluid domain modifier, ...)

Engineer plan: ?

Work plan

@Stefan_Werner, I don't have any own code for the Cycles rendering side, which I guess you guys have (and there is also the summer of code project). So integrating that with this new volume object would help.

Beyond that I'm still iterating on the basics, it will be easier to make a concrete list of remaining tasks and distribute work in a week or two from now.

There's now basic Cycles, Eevee and workbench rendering. Still many limitations, see TODO comments in the branch for the details.

Next week for me will probably be volume sequence support, and tightening up the code, in particular dependency graph integration.

For anyone who wants to help out, the tasks listed under User Interface, Workbench, Viewporting drawing, Eevee and Cycles are a good starting point. They are pretty self-contained and not likely to conflict with other changes I plan to work on.

Added this week:

  • Frame sequences for importing animations.
  • Global volume cache to let multiple datablocks automatically share the same grid memory.
  • Simpler UX for importing OpenVDB files, though Add menu and drag & drop.

Next week I plan to make the rendering and viewport drawing more complete.

Hello, I am not a programmer, I am just a user (just trying out new things), and I discovered that the search function in the Shader Editor's Shift A menu does not work, any reason for that?

@Eary, are you saying the search function is broken specifically in a build of the new-object-types branch? I can see it greyed out when there is no material, but once adding one it works for me, same as other object types.

Wait... It's fixed in the latest daily build, so never mind.

Downloaded the build from GraphicAll and imported a VDB and everything works in the viewport with Eevee, but when I try to render a frame with Eevee I don't get the expected result. There is no volume.

iss.vdb is too heavy to load on my GPU as a dense texture, but we can preview it in the viewport with wireframes now. Each box in the Fine display is 8x8x8 voxels.

While I assume such things to be sth. like the most low-priority of things to consider with this project, I'd still like to know in how far the new volume-object type could serve as groundwork for future support of pointclouds via OSL as per chapter 7.9 (page 72) in https://github.com/imageworks/OpenShadingLanguage/blob/master/src/doc/osl-languagespec.pdf?

Oh and sorry in advance in case this is the wrong place to ask this. :-)

Point-cloud sampling in OSL would share no code with the volume object, so basically unrelated. The current pointcloud texture converts point clouds to a volume, but really that's too inefficient.

Importing and rendering or shading vdb work fine but not with sequence. That only works in the viewport but the render is empty.

Still such a great addition to blender. Thanks Brecht for the work on it.

We're reviewing an in-house patch right now that's per-object (not per-shader) step size as a user parameter, not determined automatically at the moment. Rationale for per-object is that we tend to reuse the same shader for multiple VDB objects, which may have different resolutions and densities.

We might also have a patch for eulerian motion blur soon.

We have some in-house code for CPU-only sparse grids using OpenVDB directly. It's not necessarily pretty and it comes with performance penalties, not sure how useful this will be for the general audience.

I agree per-object step size makes more sense, I was thinking about changing it to that. Probably also change it from step rate to step size, but still with a way to fill it in automatically.

We wouldn't use OpenVDB directly, since we want it to work on the GPU too, and the OpenVDB implementation in Interpolation.h has poor performance. I'm hoping we can do sparse volume rendering in Cycles for 2.83 since it would be really nice to render complex volumes, but probably I won't have time for it.

Any plans to access voxel data for particle system? Like to control density of VDB animation. Thank you for more info.

Any plans to access voxel data for particle system? Like to control density of VDB animation. Thank you for more info.

One of my goal was to meshing volumes (that could be done with particles generated from density with Metaballs assistance in 2.79 https://blender.stackexchange.com/questions/181773/meshing-a-smoke-simulation/182438#182438 ), but since this way is completely buggy (due the lag of particle refresh and reassigning the Voxel Data issue) it makes voxel animation impossible in 2.79 and inaccessible in 2.83 for now, right?

@FilipMond this will become possible with D4960, there is no Blender volume object involved in that.

For some reason this new update D9141 was not posted in here, and the volume to mesh modifier checkbox is still not checked, I was not aware of its existence until somebody told me about this today. I was like, no way, I subscribed to this post, how come I am knowing this later than you, lol.
