Request for Proprosal

This page lists the projects for which Khronos is currently seeking contractor resources through its Request for Proprosals (RFP) process.   Typical contracted projects include generating conformance tests, creating API tools and SDKs, and catalyzing open source API implementations.   Any company, whether a Khronos member or not, is cordially invited to contact us on the project contact email, and we will be happy to answer any questions and assist you if you wish to submit a proposal.

Khronos NDA
Many RFPs contain Khronos confidential information, in which case the RFP documents will not be posted below, but non-member companies should send an executed copy of the Khronos NDA to the Contact Email listed in the project below with a request for a copy of the RFP document: Download NDA

Khronos Members
If your company is a Khronos member, all RFP information is covered by your membership NDA and is posted directly on the member-only site.

Contractor Agreement
If you are interest to bid, please be aware that all Khronos engineering projects are conducted under the standard Khronos Contractors Agreement. Additionally, contractors will be required to execute the Khronos membership agreement, with membership fees waived, for the duration of the project so they are enabled to participate in Khronos working group meetings.


Project Goal

This project is to build an app that runs on iOS. The app needs to meet the Requirements and be ready for submission to Apple’s App Store. There may be a second phase to this effort. That will be determined after this work is complete based on community feedback and other sources. The second phase and collecting community feedback is not within scope of this effort.

The source code and documentation will be released as open source material. It is not a requirement to use existing open-source software to build this app; however, it is probably necessary to do so to meet the budget limitations.


The following items must be delivered by the end of the contract

  1. All items in 4.3 Interim Deliverables

  2. Source code that is releasable with an Apache 2.0 license or equivalent. Other licenses may be acceptable and may be proposed. Anything not explicitly indicated will assumed to be Apache 2.0

  3. iOS compiled binaries that can run on the latest version of iOS at the time of the RFP release.

  1. Embedded documentation consistent with the style and use of other iOS apps

  2. A pull request against a Khronos identified GitHub repo for all material related to the app including, but not limited to, source code, documentation, and build instructions.

  3. Draft blog post describing the app and how it can be used.

  4. Final presentation to 3D Formats Working Group showing all features of the app on an iOS device.

  5. Application uploaded to the 3D Formats Working Group’s App Store Connect account and submitted for App Store review.

The contractor shall submit the following deliverables at the specified dates.  All deliverables (including verbal and written) are to be in US English.

Ownership and licensing of the work is specified in the Contractor's Agreement.
