setExternalImage

[main]
open fun setExternalImage(engine: Engine, eglImage: Long)

Specifies the external image to associate with this Texture.

This Texture instance must use SAMPLER_EXTERNAL.

Typically the external image is OS specific, and can be a video or camera frame. There are many restrictions when using an external image as a texture, such as:

• only the level of detail (LOD) 0 can be specified
• only NEAREST or LINEAR filtering is supported
• the size and format of the texture is defined by the external image

Parameters

main

engine	Engine this texture is associated to. Must be the instance passed to Builder.build().
eglImage	An opaque handle to a platform specific image. Supported types are eglImageOES on Android and CVPixelBufferRef on iOS.
On iOS the following pixel formats are supported:

• Copy

  `kCVPixelFormatType_32BGRA` -     `kCVPixelFormatType_420YpCbCr8BiPlanarFullRange` |
