It is assumed that the user has a basic command of visualization programs such as VMD and has had at least some experience launching and retrieving example tutorial jobs to the cluster, as shown in our introductory molecular dynamics tutorial. The aim of this tutorial is to give more advanced lessons in setting up and preparing molecular dynamics jobs for submission to the HPC cluster. Tutorials created by Mike Kuiper, edited by Thomas Coudrat. Note: this tutorial describes the use of Snowy, but all these steps can be carried out on Barcoo by substituting every instance of snowy for barcoo. Login on, select ‘Software agreement’, ‘Add software’, ‘NAMD’. Users are required to agree to these requirements to use NAMD on the Melbourne Bioinformatics HPC clusters. Important: NAMD has specific licencing requirements. Please bring along your laptops with the following installed before arriving: If you are not familiar with using the command line, please also attend the Introduction to Unix workshop. It is recommended that participants attend Introduction to High Performance Computing prior to this workshop. This workshop is intended for scientists interested in learning the basics of running molecular dynamics on a HPC cluster. Download the output and visualise the preliminary results.Submit a basic molecular dynamics job on the cluster.Log onto a high performance computer cluster.Finally we will download the results back to our local computer to visualize with VMD.Īt the end of the course, you will be able to: We then upload this directory to the cluster where we submit the job. We initially download a copy of the directory to our local computer where we then build up the input files using VMD. MD tutorial - Building input files (this tutorial): In this tutorial we will be introducing a more sophisticated directory structure using scripts to direct the output and run the job. Once the job is finished, we will download the data to your local computer and visualize the trajectory with VMD. Here we will simply copy across a bare minimum directory containing input files ready to go for a short NAMD simulation. MD tutorial - Introduction to cluster computing: If you have never launched a job on a cluster before, this tutorial is for you. Each tutorial is designed to be stand alone, start where you feel most comfortable and skip the exercises that are too simple. As students have a vast range of skill levels and requirements, the tutorials are divided into two parts described below. In the following tutorials we will be logging on a high performance computer (HPC) to submit NAMD molecular dynamics (MD) jobs and visualising the results with the molecular visualization program VMD.

I find the page How to rotate a Three.js Vector3 around an axis?, but it just let a Vector3 point rotate around the world axis?Īnd I have tried to use matrixRotationWorld as += x * Math.PI / += y * Math.PI / += z * Math.PI / 180īut it doesn't work, I don't whether I used it in a wrong way or there are other ways. Then the cube can rotate, but the problem is the cube rotate on its own axis,so after it has rotated, it can't rotate as expected. = grid * = grid * geometry, = new THREE.Mesh geometry, += y * Math.PI / += x * Math.PI / += z * Math.PI / 180 Material = new THREE.MeshLambertMaterial įor i in = new THREE.Mesh new THREE.CubeGeometry(grid, grid, grid) Geometry = new THREE.CubeGeometry grid, grid, grid I want to rotate my 3D cube in one of my game. I have a great problem about the rotation in three.js
