EquirectangularToCubemap

actual class EquirectangularToCubemap(context: IBLPrefilterContext) : AutoCloseable

Converts an equirectangular image to a cubemap.

The input equirectangular texture must:

Be a 2D texture (width == 2 * height)
Have all mip levels allocated
Have SAMPLEABLE usage

Parameters

context
