REDsdk 5.2 API Changes

File name	Change details
ARTIAssetManager.h	New methods and defines ART_GEOMETRY_AO_GROUND_FIELD_RESOLUTION: This is the fixed size of a geometry ground texture. New ART::IAssetManager::BuildGeometryREDGraph, simpler than other methods and accessing only the created graph. Modified methods ART::IAssetManager::GenerateGeometryVertexAO: More precise specification for the ground.
ARTIGeometry.h	New methods ART::IGeometry::GetMemoryUsage to get an estimate of the CPU & GPU memory taken by the geometry. ART::IGeometry::GetMaterialsCount, ART::IGeometry::GetMaterial: Material access API. A set of selection handling methods to have a selection feedback for some parts in the geometry. Modified methods ART::IGeometry::SetGroundAOCache, now specifying the size of the source AO information.
ART::ILight.h	Removed defined ART::LT_SPOT: Is now assimilated to the ART::LT_POINT with a spot angle. New methods ART::ILight::GetPhysicalColor, ART::ILight::SetPhysicalColor: Setup a physical light. ART::ILight::GetLuminousFlux, ART::ILight::SetLuminousFlux: Setup a physical light.
ARTIMaterial.h	All new methods for the setup and configuration of a material.
ARTIOptions.h	New methods ART::IOptions::SetAllDefaultOptions: Reset everything to default values. ART::IOptions::ForcePrismsRealMeshShadows, ART::IOptions::IsForcedPrismsRealMeshShadows: Override prisms shadow settings. ART::IOptions::SetPrismsMeshFadeOffset, ART::IOptions::GetPrismsMeshFadeOffset: Shift prisms meshes display distances. ART::IOptions::SetPrismsExactSpawn, ART::IOptions::GetPrismsExactSpawn: Set an increased accuracy for prisms scattering. ART::IOptions::SetPrismsSpawnOffset, ART::IOptions::GetPrismsSpawnOffset: Shift the prisms scattering landscape subdivision. ART::IOptions::SetPrismsPassesCount, ART::IOptions::GetPrismsPassesCount: Set the number of prisms rendering passes. ART::IOptions::SetCloudsRelighting, ART::IOptions::GetCloudsRelighting: Specify the amount of sky relighting generated by clouds. ART::IOptions::SetFullSceneAntiAliasing, ART::IOptions::GetFullSceneAntiAliasing: Setup FSAA. All SSAO and SSR new methods. Modified methods ART::IOptions::SetPlanetGeometricalUpdateTime becomes ART::IOptions::SetPlanetGeometricalOpsPerFrame: uses a fixed number of operations rather than a timer. Generates more stable FPS.
ARTIWorld.h	New methods ART::IWorld::IsLandscapeUpdateDone: Get an information on the landscape synchronization. ART::IWorld::GetWindow: Get the REDsdk rendering window. ART::IWorld::SetOffscreenRendering: Force the rendering of REDart into an auxiliary VRL to let the main window VRL free. New picking methods: ART::IWorld::PickCloudsCovers, ART::IWorld::PickCustomShapes. New HTC Vive VR methods: ART::IWorld::StartOpenVRRendering, ART::IWorld::StopOpenVRRendering, ART::IWorld::IsOpenVRRendering. Modified methods ART::IWorld::Pick: More details on picked items.
RED.h	New defines for error code handling.
REDBoundingSphere.h	New methods for handling AABBs (informative only. AABBs are not used internally).
REDIImage2D.h	New methods RED::IImage2D::ScaleNormalMap: Change the intensity of a normal map.
REDImageTools.h	New methods RED::ImageTools::Resize: Image resizing helper with complete filtering. RED::ImageTools::ConvertFormat: Image format conversion tool. RED::ImageTools::ConvertMetallicToRealisticMaterial: Conversion of a PBR material to a realistic material.
REDIMaterial.h	New methods RED::IMaterial::UpdateShader: Update any shader in place within the material configuration. RED::IMaterial::RemoveShaderFromLayerSets, RED::IMaterial::RemoveShaderFromPasses, RED::IMaterial::RemoveShader: shader list helpers. RED::IMaterial::ClearShaderLayerSet: shader list helpers. RED::IMaterial::GetShaders: Shader access with more combinations for an easier usage. Modified methods RED::IMaterial::SetupGenericMaterial: Added a real-time refraction toggle flag.
REDIMaterialController.h	New defines RED_MATCTRL_REALTIME_REFRACTION and RED_MATCTRL_REALTIME_REFRACTION_DESC for the generic material real-time refraction prop.
REDIMeshShape.h	Modified methods RED::IMeshShape::Polygon: Added a polygon normal definition flag that was implicit before.
REDIOptions.h	New options RED::OPTIONS_OPENGL_CONTEXT_DEBUG, RED::OPTIONS_OPENGL_CONTEXT_MAJOR, RED::OPTIONS_OPENGL_CONTEXT_MINOR: OpenGL context creation options.
REDIOTools.h	Modified methods RED::IOTools::Save: Added a local images source control flag.
REDIPhysicalLightShape.h	New methods RED::IPhysicalLightShape::SetIESMatrix and RED::IPhysicalLightShape::GetIESMatrix: custom control of the IES orientation from within the light.
REDIResourceManager.h	New methods RED::IResourceManager::SetAliveImagesCheck, RED::IResourceManager::IsAliveImagesCheck: Turn on or off the testing of images addresses during updates. Can be disabled for performance critical applications. RED::IResourceManager::SetSynchronizationLock, RED::IResourceManager::IsSynchronizationLock: turn on or off the internal synchro lock for performance critical applications.
