ToneMapper

open class ToneMapper

Interface for tone mapping operators. A tone mapping operator, or tone mapper, is responsible for compressing the dynamic range of the rendered scene to a dynamic range suitable for display. In Filament, tone mapping is a color grading step. ToneMapper instances are created and passed to the ColorGrading::Builder to produce a 3D LUT that will be used during post-processing to prepare the final color buffer for display. Filament provides several default tone mapping operators that fall into three categories:

• Configurable tone mapping operators
• • GenericToneMapper
  • AgXToneMapper
• Fixed-aesthetic tone mapping operators
• • ACESToneMapper
  • ACESLegacyToneMapper
  • FilmicToneMapper
  • PBRNeutralToneMapper
  • GT7ToneMapper
• Debug/validation tone mapping operators
• • LinearToneMapper
  • DisplayRangeToneMapper
