virtual DecalHandle AcquireDecal ()=0
 Creates a new decal which can be referenced by the returned DecalHandle. Must be released via ReleaseDecal() when no longer needed.
 
virtual bool ReleaseDecal (DecalHandle handle)=0
 Releases a Decal.
 
virtual DecalHandle CloneDecal (DecalHandle handle)=0
 Creates a new Decal by copying data from an existing DecalHandle.
 
virtual void SetDecalData (DecalHandle handle, const DecalData &data)=0
 Sets all of the the decal data for the provided DecalHandle.
 
virtual void SetDecalPosition (DecalHandle handle, const AZ::Vector3 &position)=0
 Sets the position of the decal.
 
virtual void SetDecalOrientation (DecalHandle handle, const AZ::Quaternion &orientation)=0
 Sets the orientation of the decal.
 
virtual void SetDecalHalfSize (DecalHandle handle, const Vector3 &halfSize)=0
 Sets the half size of the decal.
 
virtual void SetDecalAttenuationAngle (DecalHandle handle, float angleAttenuation)=0
 Sets the angle attenuation of the decal. Increasing this increases the transparency as the angle between the decal and geometry gets larger.
 
virtual void SetDecalOpacity (DecalHandle handle, float opacity)=0
 Sets the opacity of the decal.
 
virtual void SetDecalNormalMapOpacity (DecalHandle handle, float opacity)=0
 Sets the opacity of the decal normal map.
 
virtual void SetDecalMaterial (DecalHandle handle, const AZ::Data::AssetId)=0
 Sets the material information for this decal.
 
virtual void SetDecalSortKey (DecalHandle handle, uint8_t sortKey)=0
 Sets the sort key for the decal. Decals with a larger sort key appear over top of smaller sort keys.
 
virtual const Data::Instance< RPI::BufferGetDecalBuffer () const =0
 Returns a GPU readable buffer containing the contiguous array of decals.
 
virtual uint32_t GetDecalCount () const =0
 Returns the number of decals currently in the buffer.
 
virtual void SetDecalTransform (DecalHandle handle, const AZ::Transform &world)=0
 
virtual void SetDecalTransform (DecalHandle handle, const AZ::Transform &world, const AZ::Vector3 &nonUniformScale)=0

Detailed Description

DecalFeatureProcessorInterface provides an interface to acquire, release, and update a decal. This is necessary for code outside of the Atom features gem to communicate with the DecalFeatureProcessor.
