I have a closed surface (unstructured) can I use paraview to convert it to a solid voxel (image/structured) dataset? How is this achieved?

The **Resample to Image** filter can resample data from a structured grid to an Image Data dataset.

I should have been more specific, the unstructured data is in a vector format, so not a structured grid.

I mistyped. The **Resample To Image** filter can resample data from an **un** structured grid to an Image Data dataset.

I’m not sure what you mean by “vector format”.

I’m coming from a GIS background, so vector, point-line-polygon, polyhedral (3D), a 3D closed surface - so unstructured data. This is the opposite of raster (image), voxel, or in paraview speak structured data.
I’ll experiment with the Resample to Image filter, and report back if it works, thanks.

The Resample to Image gives a wireframe bounding 3D box

You can change the **Representation** type from “Outline” to “Volume” under the _Display_ section of the _Properties_ panel. “Outline” is just the default view of the generated image data.

I get the error “This OpenGL implementation does not support the required texture size of 2097152, falling back to maximum allowed, 16384.” The dataset I have is a polygonia closed mesh with 27448 cells, it is one of the smaller ones I have and I cannot really reduce it through pre-sampling.
I guess my system is not capable of this?

I suspect that your GPU is quite old with only 1Gb of memory. You may want to use a CPU based solution for volume rendering. Switch the volume rendering mode to RayCast or OSPray.

I have a 1 year old MSI laptop with 32GB RAM with NVIDIA GTX 1070 graphics card/GPU.
I tried your suggestion and paraview crashed.

Something is wrong with your drivers.
what is the output of glxinfo ?

Not sure how to run glxinfo (I’m using windows) but in ‘about’ OpenGL states 3.2.0

I missed the fact that you are using Windows. Did you install nvidia drivers ? Which version do you have ? Is you system fully up to date ?

It is complaining **not** about the total RAM on the GPU, but the size of one dimension of a texture. 2 million texels is quite high in one dimension. By default the resampling dimensions are 100x100x100, so did you modify those somehow?
It might help us get a better idea of what you are trying to do if you can provide the small sample dataset, or at least posting an image of what the input data looks like.
