- Sceneform SDK for Android
was open sourced and archived ( github.com/google-ar/sceneform-android-sdk
) with version 1.16.0.
- This site ( developers.google.com/sceneform
) serves as the documentation archive for the previous version, Sceneform SDK for Android
1.15.0.
- Do not use version 1.17.0 of the Sceneform Maven artifacts
.
- The 1.17.1 Maven artifacts can be used. Other than the version, however, the 1.17.1 artifacts are identical to the 1.15.0 artifacts.

Public Methods
public
static
boolean
almostEqualRelativeAndAbs
(float a, float b)
Returns true if two floats are equal within a tolerance. Useful for comparing floating point
numbers while accounting for the limitations in floating point precision.
