render function

[Olivia Viessmann]

Hello, 
I am new to hoomd and would like to visualise my simulation results with a render function that takes in the snapshot as the argument: render(snapshot). 

I saw that the hoomd examples on the hoomd website have such a function. 

Could you forward me the function definition so that I could use it in my scripts?

I have fresnel installed. 

Thanks

Olivia

Olivia,

You can find the source code for the tutorials, including the render function, here: https://github.com/glotzerlab/hoomd-examples

Hi Joshua,

Wow — thanks for the fast reply. Could you sign-post me to where exactly on the git I can find the render function?
Thanks a ton
Olivia

Quick question. Has the ‘hoomd.device’ import changed?
I try to run
gpu = hoomd.device.GPU()
sim = hoomd.Simulation(device=gpu, seed=1)

But get an error that “hoomd has no attribute ‘device’”

Thanks

Hi Joshua,

Which version of hoomd should be installed to run the tutorials? According to your website I installed 

conda install -c conda-forge/label/hoomd_dev -c conda-forge hoomd

But run into incompatibilities with the tutorial.

Thanks a lot

Olivia

Olivia,

You should install v3.0.0-beta.14 following instructions in the documentation: https://hoomd-blue.readthedocs.io/en/latest/index.html

Hmmm. That’s what I did. The command I posted was from this website.

Olivia,

My apologies, I misread the command you entered.

The output of `conda install` indicates version it will install. For various reasons, conda's dependency solver may choose older versions instead of the latest. Confirm what version is in your conda environment with `conda list hoomd`.

Force install a specific version with `conda install -c conda-forge/label/hoomd_dev hoomd=3.0.0dev14`.

See conda's documentation for more details: https://docs.conda.io/projects/conda/en/latest/commands/install.html

Note: If you are installing on osx-arm64, the package 3.0.0dev14 appears to be missing and dev13 is the latest.
