API docs

This is a summary page comparing all the APIs. Click on API name to see its documentation. See what is an API.

Go to the Starter Worlds page to see Starter Worlds for all APIs on one page.

These APIs use specific versions of third-party libraries. These APIs will not change in the future, so that all runs will always work. Rather, new APIs will be added.

"Ancient Brain" APIs

The following APIs include third-party libraries and a useful Ancient Brain framework to make writing Worlds easy and short.

These APIs are useful for writing JS Worlds for this site:

API	Version	Uses canvas	Graphics libraries	AB framework	Worlds using this API	Starter Worlds
Three (AB)	2.0	Yes	Three.js	Yes	389 Worlds	Starter Worlds
Physics (AB)	1.0	Yes	Three.js, Physijs	Yes	106 Worlds	Starter Worlds
P5 (AB)	1.0	Yes	P5	Yes	39 Worlds	Starter Worlds
Canvas (AB)	1.0	Yes	None	Yes	48 Worlds	Starter Worlds

"Plain" APIs

The following APIs include third-party libraries and nothing else (no useful Ancient Brain framework). The World author has to write everything themselves.

These APIs are useful for porting JS Worlds to this site unchanged:

API	Version	Uses canvas	Graphics libraries	AB framework	Worlds using this API	Starter Worlds
Three	2.0	Yes	Three.js	No	26 Worlds	Starter Worlds
Physics	1.0	Yes	Three.js, Physijs	No	7 Worlds	Starter Worlds
P5	1.0	Yes	P5	No	1539 Worlds	Starter Worlds
Canvas	1.0	Yes	None	No	7 Worlds	Starter Worlds
Webpage	1.0	No	None	No	52 Worlds	Starter Worlds

Earlier version APIs

Worlds with an earlier version of the API will run fine. Just that a later version of the API exists. These earlier APIs will exist forever, so the Worlds will run forever. And you can go on using the earlier API forever.

Over time, we expect most Worlds on this site to have APIs in this section rather than in the "latest version" section. But this is not a problem.

API	Version	Uses canvas	Graphics libraries	AB framework	Worlds using this API	Starter Worlds
Three (AB) (1.0)	1.0	Yes	Three.js	Yes	1032 Worlds	None
Three (1.0)	1.0	Yes	Three.js	No	1 World	None

Call for partners!

If you are interested in writing a programming course, textbook or tutorial videos, Ancient Brain is looking for partners. We will work with you, and integrate your course into the site. This is an opportunity for someone looking to develop a course or textbook to partner with a site to support it and promote it.
