Rendering

Types describing geometry, views, and symbology for consumption by a display system.

Classes

Name Description  
ColorIndex Describes the color(s) of the vertices of a MeshArgs or PolylineArgs.  
Feature Describes a discrete entity within a batched RenderGraphic that can be  
FeatureAppearance Defines overrides for selected aspects of a Feature's symbology.  
FeatureIndex Describes the set of Features associated with a MeshArgs or PolylineArgs.  
FeatureOverrides Specifies how to customize the appearance of individual Features, typically within the context of a Viewport.  
FeatureTable Defines a look-up table for Features within a batched RenderGraphic.  
ImageBuffer Uncompressed rectangular bitmap image data.  
ImageSource Image data encoded and compressed in either Jpeg or Png format.  
NonUniformColor As part of a ColorIndex, describes per-vertex colors for a MeshArgs or PolylineArgs.  
OctEncodedNormal Represents a 3d normal vector compressed into a single 16-bit integer using oct-encoding.  
RenderMaterial Represents a material which can be applied to a surface to control aspects of its appearance such as color, reflectivity, texture, and so on.  
RenderTexture Represents a texture image applied to a surface during rendering.  
TextureMapping Describes how to map a RenderTexture's image onto a surface as part of a RenderMaterial.  

Enumerations

Name Description  
BatchType Describes the type of a 'batch' of graphics representing multiple Features.  
FeatureIndexType Describes the type of a FeatureIndex.  
FeatureOverrideType Options for overriding element appearance.  
ImageBufferFormat Format of an ImageBuffer.  
ImageSourceFormat The format of an ImageSource.  
NormalMapFlags Flags applied to a NormalMapProps.  
TextureMapUnits Describes the units in which a TextureMapProps' scale is expressed.  

Global Functions

Name Description  
isPowerOfTwo Returns whether the input is a power of two.  
nextHighestPowerOfTwo Returns the first power-of-two value greater than or equal to the input.

PolylineFlags Flags describing a PolylineArgs.  
RenderFeatureTable Representation of a FeatureTable suitable for use with RenderSystem.createBatch.  
RenderMaterialAssetMapsProps Describes different types of textures to be applied to a surface material to alter its appearance.  
RenderMaterialAssetProps Describes the graphical properties of a RenderMaterialElement as part of a RenderMaterialProps.  
RenderMaterialProps Properties that define a RenderMaterialElement.  
TextureMapProps As part of a RenderMaterialAssetProps, describes how to map a RenderTexture's image to the triangles of a mesh to which the material is applied.  
ThumbnailFormatProps Metadata about a thumbnail image.  
ThumbnailProps Describes a thumbnail image for an IModel or ViewDefinition.
