It's not rust, it's a layer of seasoning!

Skillet

Skillet is a lightweight, deep-fried, rust application for interactive scientific visualization with vtkio and glium.

Compare skillet with ParaView:

Skillet	ParaView

Run

Provide the .vtu filename as an argument:

cargo run ./res/teapot.vtu

You can try one of the provided .vtu files in the ./res/ directory.

Equivalently:

cargo build
# or "cargo build --release"

./target/debug/skillet.exe ./res/teapot.vtu

# or "./target/release/skillet.exe ./res/teapot.vtu"

Mouse controls

Mouse controls mostly follow the ParaView conventions.

LMB drag: rotate

LMB means "left mouse button".

Mouse wheel scroll: zoom

MMB drag: pan

RMB vertical drag: z pan

Z pan is similar to scroll zooming.

Key controls (case-sensitive)

c: cycle vector/tensor component

d: cycle point data or cell data array

e: toggle edge visibility

m: cycle colormap

w: cycle warp by vector point data array

Cell data arrays, scalars, and tensors cannot be used as a warp basis. Only point data vector arrays are a valid basis.

To turn off warp by vector, continue cycling with w until all vectors have been cycled through.

Ctrl+w: Decrease warp by vector scale factor

Shift+w: Increase warp by vector scale factor

Data array	Skillet support?
Point data	✔

Vectors	✔
Tensors	✔

Field attributes	❌

Cell types

Skillet displays color contours on surfaces. As such, it doesn't make sense to try to display 0D or 1D cells like VTK_VERTEX or VTK_LINE. I might implement types like triangle strips and quadratic cells if I can get some test data.

File formats

Only binary/ascii .vtu files are supported. Most formats can be converted to .vtu in ParaView like this:

1. Filters -> alphabetical -> append dataset -> apply
2. File -> save data -> VTK UnstructuredGrid files (*.vtu) -> OK -> data mode binary or ascii

File	Extension	Skillet support?

Operating systems

OS	Skillet support?
Windows	✔
Ubuntu	❌

On Ubuntu, the glutin dependency has an issue finding the fontconfig package. Your mileage may vary: https://unix.stackexchange.com/questions/330068/package-fontconfig-not-found-despite-having-installed-libfontconfig1-dev
