Frequently Asked Questions

What is the D3pth engine?

D3pth engine is a browser-side JavaScript engine for creating spatial, 3D-like website layouts from regular HTML elements without requiring WebGL or canvas. It uses CSS transforms, configuration, and finite state machines to control depth, movement, and transitions.

Who develops the D3pth engine?

D3pth engine is a commercial software product developed and licensed by D3pth lab s.r.o. under the direction of Čeněk Svoboda, CEO of the company.

I build websites for clients. Can I buy a licence?

Yes. You may buy a Demo and its corresponding Licence for your own project or for a client. During checkout, you specify the Licence holder and one licence target for each purchased Demo.

One purchased Demo may be licensed for one domain including all of its subdomains, one exact host name, or one exact IP address. localhost and 127.0.0.1 are available for development and testing connected with the licensed deployment and do not consume the paid licence target.

The Licence holder may be the Buyer, the Buyer's company, a client, or another person or legal entity. The Buyer confirms the applicable EULA during checkout. If the Buyer is also the Licence holder, that confirmation constitutes acceptance. If they are different, acceptance by the Licence holder follows the rules stated in the applicable EULA.

Does D3pth lab need access to my server or website infrastructure?

No. A standard Licence does not require us to access your server, database, CMS, hosting account, source repository, or customer data. If you separately purchase a service that requires access or files for deployment, the required cooperation is handled as part of that service.

Can we reverse engineer or deobfuscate the code?

No. The D3pth engine and License Notice must remain complete and unchanged as supplied. The D3pth engine may not be modified, transformed, deobfuscated, decompiled, disassembled, or reverse engineered, and the License Notice may not be removed, obscured, detached, or altered. The applicable EULA and Order define the permitted deployment and use.

Is D3pth engine responsive?

D3pth engine does not automatically guarantee a responsive result. Responsiveness depends on the website layout, Demo Materials, external CSS or JavaScript, configuration, states, and transitions. The final implementation must be tested for the intended viewport sizes and devices.

What happens after I place an order?

Checkout records the Buyer details, Licence holder details, Licence holder email address, and one licence target for each purchased Demo: one domain including all of its subdomains, one exact host name, or one exact IP address.

The Buyer confirms the applicable EULA during checkout. If the Buyer is also the Licence holder, that confirmation constitutes acceptance. If the Licence holder is different, acceptance by the Licence holder follows the applicable EULA.

After payment, we prepare the Licence and Licensed Materials and normally send them to the Licence holder email address within 24 hours. We contact the Buyer or Licence holder only if the Order information is incomplete, unclear, or cannot be used to issue the Licence. If we cannot issue the Licence, the Order is refunded.

What are Demo Materials?

Demo Materials are the editable parts of a supplied example, such as HTML, CSS, JavaScript other than the D3pth engine, configuration, text, graphics, layouts, and templates. They do not include the D3pth engine, License Notice, third-party materials, or Licensor Marks except where expressly stated otherwise.

Demo Materials may be adapted and otherwise used as permitted by the applicable EULA. Before public deployment or provision outside implementation for the Licence holder, the identifiers required by the EULA must be removed from the Demo Materials. This does not permit any change to the D3pth engine or License Notice.

Do production licences include the demo hit counter?

No. Production licences are issued without the demo hit counter or tracking code. The D3pth engine itself does not require D3pth lab s.r.o. to receive visitor analytics or tracking data from your production deployment.
