Licencing and Pricing

This page provides information about licensing from a practical point of view.

If you are interested in the legal aspects, please refer to the Terms and Conditions.

Tinman 3D licences are one-time purchases and do not include any future obligations, which means that there are no subscriptions and no recurring payments. Expired licences may be prolonged at any time by purchasing an update, at your own discretion.

Figure 1. Tinman 3D SDK Licencing Flow

In case you are looking for ready-to-use terrain datasets based on commercial geodata sources, please contact sales@tinman3d.com and we will provide you with a quote for the terrain data you need.

If you would like to receive custom services from Tinman 3D, such as consultancy, training or software development, please send a request to sales@tinman3d.com. We will get back to you with a quote that is tailored to your specific requirements.

Overview

The Tinman 3D SDK can be downloaded and evaluated instantly, free of charge, without creating an online account and without time limit.

How to evaluate the SDK

If applicable, use the instant evaluation licence key, see Quickstart.
Submit your evaluation request by sending an email to sales@tinman3d.com.
Receive a Licence Certificate document, which contains the login credentials for download.
Download the Tinman 3D SDK:
- Get the PREVIEW version via web download.
- Get the RELEASE version via web download.
- Get the RELEASE version via Git checkout.
Follow the instructions of the Getting Started page.

The following licensing scenarios exist for non-evaluation use:

Development (User, Site, Academic): A licence key is provided at runtime, temporarily activating all Tinman 3D SDK versions, only for the current user, only on the current machine, for any application/product, only during the licence period.
Distribution (Product, Company, Full): A licence key is distributed along with a customer product, perpetually activating only those Tinman 3D SDK versions within the update period, for any user, on any machine, only for that product, only in non-debug mode.
Content (Source): An unlock key is used with tinmanpc unlock to decrypt the Tinman3D.SDK.Source-*.zip.lic packages, only for those Tinman 3D SDK versions within the update period.

Customers receive a licence certificate document that contains all purchased licence keys in one place. This self-contained document may be archived in electronic or printed form, preferably both.

For non-evaluation use, the following SDK components require a valid licence:

Stand-alone tools: The codex, tinmanpc and tinman3d-workshop tools run in feature-locked evaluation mode by default and may be unlocked with a Development licence key.
Software libraries: The Core, Terrain and Engine libraries must be activated with a Development or Distribution licence key during application startup.
Source code: The source code of the Core, Terrain, Engine and Processor libraries must be decrypted with a Content unlock key, separately for each programming language (e.g. C#, C++).

Licence key checking is 100% offline, there is no online activation step involved.

The following table shows the possible combinations of licences with their practical use:

Table 1. Licence combinations and typical progression
#	EVAL	DEV	DIST	CONT
1.	no	no	no	-	use of SDK not possible
2.	yes	-	-	-	evaluation only, no product development development with full DEBUG^[1] capabilities
3.	-	yes	no	-	development with full DEBUG^[1] capabilities additional support / training available

Order Process

This section explains how to order a licence for the Tinman 3D SDK.

How to order

Submit your licence request by sending an email to sales@tinman3d.com.
Receive a formal non-binding purchase document per email, which includes a tailored quote. This document has a unique Document Number (also referred to as Order Number or Invoice Number).
Make a purchase decision and follow the payment instructions, for example a direct SEPA / SWIFT / Bitcoin transfer or a payment via a 3rd-party payment provider.

The payment process is linked uniquely to the tailored quote in the purchase document, both via the Document Number and the MD5 checksum of the whole purchase document:
```
Tinman 3D SDK Licence / T3D-00000 / MD5-00000000000000000000000000000000
```
Depending on the payment process, you will either receive a separate invoice document or the purchase document itself will act as the formal invoice document.
Receive your (updated) Licence Certificate per email and per secure download.

Apply your licence key(s):

Activate the Tinman 3D SDK with your Licence Keys.
Unlock additional content with your Unlock Keys.

You can use the Licence Bakery tool to assemble metadata.

Licence keys are delivered as soon as payment has been received.
Licence certificate updates are usually processed within one workday.

After purchasing a licence key that is bound to metadata, you can request extra licence keys for different metadata free of charge, given that the requested metadata correlates with the licensed product and you as the licence owner.

Get extra licence keys

Generate licence request files for the metadata you need.
For example: tinman_3d.licence-request.user.id-C9F9A1B9.json.txt.
Please refer to Licence Requests for details.
Lookup your Order Number (for example: T3D_XYZ12). You can find that number on the purchase document and the invoice document.
Send an email to sales@tinman3d.com, including the above information. Handling of extra licence key requests involves manual review, so please allow us a small number of workdays to process your request. In most cases, extra licence keys can be issued almost instantly.
The extra licence keys will be added to your Licence Certificate.

Please contact sales@tinman3d.com if you have any more questions regarding licensing.

Licence Certificate

A self-contained licence certificate document is provided for your licence purchases, licence updates and extra licence keys. Please archive this document in electronic form or as a hard copy.

Licence Items

The Licence Certificate specifies the licensee, who can either be a legal entity or an individual person.

Each certificate contains a number of licence items, where each item belongs to one of the types that are listed in this section. Each licence item has one or more Licence Keys, which are used to activate the SDK.

Legal entities need to have own licence items for their employees. Although an employee - as an individual person - may have own licence items, these cannot be used for work on behalf of the employer.

Licence Keys

Before the Tinman 3D SDK can be used by an application, it must be activated. Activation is done by providing one or more licence keys during application startup.

Nature of a licence key

A licence key is a base-85 number with 100 digits, and looks like this:

An example licence key

CIk!6Dh6Ui;lSE+Z{{jx7$Y~8,#TSt~o%CK#(e,F#O9.d;fGc+bU35%HVl;[.+s#@h.bo1~{riL.4|UreHfeuac}5ZV~DBocxU}@

The base-85 digits

!#$%()*+,-.0123456789:;=?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[^_abcdefghijklmnopqrstuvwxyz{|}~
^         ^         ^         ^         ^         ^         ^         ^         ^    ^
0         10        20        30        40        50        60        70        80   85

The characters of a licence key are "programming-language-safe", so the plain key value can be put into XML files or string literals without escaping.

To provide a licence key from code, call the LicenceKey method on the Tinman domain. This is usually done for perpetual licences.

To avoid that a licence key ends up as a string literal in an application binary, the Licence Bakery tool can be used to generate a source code fragment which generates the licence key value using obfuscated arithmetics.

As an alternative, a single licence key can be provided by setting an environment variable, which is usually done for Development licences.

Licence key environment variable

TINMAN_3D_LICENCEKEY = ...

Metadata Binding

A licence key is usually bound to specific metadata, using asymmetric encryption.

A licence key will only work if the metadata values found in the current execution context correlate with those that have been used to create the key.

Development

In addition to having an expiration date, development licence keys are usually bound to the local machine and may only be used there:

Machine login user (see LicenceFlags.MachineUser)
Machine login domain (see LicenceFlags.MachineDomain)
Machine hardware code (see LicenceFlags.MachineCode)

Distribution

Although distribution licence keys do not expire, they are bound to the release dates of the Tinman 3D SDK and cannot unlock future releases.

The legal metadata binding associate a distribution licence with a specific product and/or company:

Legal product name (see LicenceFlags.LegalProduct)
Legal company name (see LicenceFlags.LegalCompany)
Legal copyright notice (see LicenceFlags.LegalCopyright)
Legal trademark notice (see LicenceFlags.LegalTrademark)

The program metadata binding associates a distribution licence with a program binary file:

Program file name (see LicenceFlags.ProgramFile)
Program file hash (see LicenceFlags.ProgramHash)
Program title (see LicenceFlags.ProgramTitle)
Program version (see LicenceFlags.ProgramVersion)

A licence key may include any combination of the above metadata bindings.

You can use the Licence Bakery tool to obtain metadata information quickly.

To determine the metadata from code, you can generate a licence request file, see Licence Requests.

Licence Requests

Licence keys are generated from the information found in licence requests. A licence request is a JSON text file in UTF-8 encoding that contains all required information.

Licence requests can be generated using the Licence Bakery tool or from code by calling the LicenceDomain.Request method on the Tinman domain.

Unlock Keys

Unlock keys are used to access locked content of the Tinman 3D SDK, for example:

Source code (C++ / C#)
Digitally licensed content, such as high-quality commercial raster datasets and texture pyramids.

Use the Geodata Processor / unlock command to apply an unlock key to a locked content archive.

Risk Assessment

This section describes potential risk scenarios that could arise (being caused by higher force, for example) after having spent money for Tinman 3D SDK licensing and having invested development time using the SDK.

§1 - Unexpected Suspension of Online-Services

For whatever reason, the online services of Tinman 3D are no longer available:

https://www.tinman3d.com
This is the landing page. It only provides basic information.
https://manual.tinman3d.com
The Tinman 3D SDK manual can be browsed online here.
https://download.tinman3d.com
The Tinman 3D SDK packages may be downloaded from here.
https://data.tinman3d.online
Geodata Examples are provided for streaming and/or download here.
https://licence.tinman3d.com
Licence Certificate documents may be downloaded from here.
NuGet Packages
For convenience, the .NET assemblies of the Tinman 3D SDK are hosted here.

§2 - Unexpected Suspension of Licencing

For whatever reason, Tinman 3D is no longer able to provide new licence keys for the Tinman 3D SDK.

§3 - Unexpected Suspension of Support

For whatever reason, Tinman 3D is no longer able to provide support via email or to communicate at all.

§4 - Unexpected Suspension of Custom Services

For whatever reason, Tinman 3D is no longer able to provide custom services.

§5 - Unexpected Suspension of Development

For whatever reason, Tinman 3D is no longer able to further develop or maintain the Tinman 3D SDK.

To guard against these risks, we recommend to follow these guidelines:

Always download and archive all Tinman 3D SDK packages for the version you are using. This will guard against §1.2, §1.3 and §1.6.
Always download and archive your Licence Certificate documents, including printed versions on paper. This will guard against §1.5.
Do not rely on being able to access the Geodata Examples online. Instead, download datasets as a whole and host them on your own infrastructure. This will guard against §1.4.
Consider having a perpetual Distribution licence in place, to make sure that none of your software development processes break when your Development licence expires (see below). This will guard against §2.
Consider having a Source Code licence in place, in order to be able to perform code review, modifications and bug-fixes on your own. This will guard against §3 and §5.
Always download and archive your Task Document for the custom services you receive from Tinman 3D and actively communicate with the developer who is responsible for you. This helps to guard against §4.

If you are using one or more tools of the Tinman 3D SDK for your software development processes, please take the following into account:

The tinman3d_workshop application will run in feature-locked mode when there is no Development licence. Instead of integrating manual steps into your process, consider using scripting to perform automated steps via the tinmanpc tool.
The tinmanpc tool will run in feature-locked mode when there is no Development licence. By using the API directly, the features of tinmanpc may be integrated into your own toolset. Consider unlocking that toolset with a Distribution licence.
The codex tool will not run without a Development licence. In this case, the whole workflow must be performed manually, which most likely causes degradation in productivity and code quality. The Code-X Framework is available with a Content licence, which makes it possible to integrate the features of codex into your own toolset. Consider unlocking that toolset with a Distribution licence.

1. See DEBUG vs. RELEASE.

2. Licence keys are bound to the specified metadata using asymmetric encryption.

3. No separate licence key is necessary, you can start your evaluation right after downloading the Tinman 3D SDK.

4. Extra licence keys are issued for free, provided that the bound metadata correlates with the licensed product and licence owner.
