Greatly simplifies creation of impressive images allowing for an instant feedback.ĭespite the widespread use of hardware-accelerated Tachyon implementations today, the legacy CPU-only Tachyon implementation is preferred in some cases.Enables quick creation of photorealistic animations.Tar -xf vmd-1.9.tar.gzįull-time ray tracing is available as a special rendering mode: rendermode Tachyon RTX RTRT # There is no need to change anything below this line export VMDINSTALLBINDIR = $VMDHOME/binĮxport VMDINSTALLLIBRARYDIR = $VMDHOME/lib # Configure where to install vmd export VMDHOME = $HOME/scratch/VMD Real Time Ray Tracing using NVidia RTX cores is supported in version 1.9.4a55 of VMD on Linux platform. Real Time Ray Tracing solves limitations of the Tachyon OptiX interactive ray tracer by providing full-time ray-tracing in the main OpenGL VMD window. It not a full-featured interactive implementation, but it is useful for improving the final rendered image.Ĭompare normal, glsl and OptiX rendering modes. You can rotate, scale, translate with a mouse, and you can turn on/off AO and DoF. It allows only for a limited interactive functionality. When you close the interactive window the final image is saved in file. The interactive ray tracer opens a new graphical window in which you can preview ray-traced rendering and interact with it using a mouse. On Alliance systems Tachyon OptiX is available by loading cuda and vmd/1.9.4a43 modules. Nvidia OptiX and Intel OSPRay are hardware-accelerated ray tracers capable of interactively rendering photorealistic global illumination. Tachyon OptiX and Tachyon OSPRay interactive ray tracers Best for computers with NVidia RTX GPUs (works also on NVidia GPUs without RTX cores).
