ParaView/VTK Software for Immersive Scientific Visualization Support

The National Institute of Standards and Technology (NIST) issued a special notice stating its intent to negotiate a sole-source, firm-fixed-price purchase order with Kitware, Inc. for follow-on support services related to ParaView/VTK software for immersive scientific visualization. This is a notice of intent only and not a request for quotations. The anticipated period of performance is 12 months.

NIST's High Performance Computing and Visualization Group within the Information Technology Laboratory requires specialized support to transition its Immersive Visualization Environment to the ParaView open-source framework and to improve the platform's virtual reality capabilities. The work is intended to support NIST's high performance computing and visualization research while advancing ParaView toward the OpenXR standard and leveraging newer visualization hardware capabilities such as real-time path tracing and global illumination.

Key technical objectives include adding the open-source Slang GPU shading language for the next-generation WebGPU rendering backend in VTK, implementing scenegraph capability within ParaView to align with NIST's internal frameworks, and developing interfaces between ParaView and external tools to minimize disruption across research projects in nanotechnology, medical, and materials science. NIST states that this requirement is a follow-on effort tied to prior phases of work.

According to the notice, the sole-source justification is based on Kitware's role as the developer and manager of the VTK library and ParaView software environment. NIST indicates that only Kitware can ensure that new code will be acceptable for incorporation into the open-source library and provide the level of repeatability and precision required for research software integration, enhancement, and transition.
