RenderSystem.Options Interface
Options passed to IModelApp.supplyRenderSystem to configure the RenderSystem on startup. Many of these options serve as "feature flags" used to enable newer, experimental features. As such they typically begin life tagged as "alpha" or "beta" and are subsequently deprecated when the feature is declared stable.
Properties
| Name | Type | Description | |
|---|---|---|---|
| antialiasSamples | undefined | number | Initial antialias setting | |
| devicePixelRatioOverride | undefined | number | If defined, this will be used as the device pixel ratio instead of the system's actual device pixel ratio. | |
| disabledExtensions | undefined | WebGLExtensionName[] | WebGL extensions to be explicitly disabled, regardless of whether or not the WebGL implementation supports them. | |
| displaySolarShadows | undefined | boolean | If true, display solar shadows when enabled by ViewFlags.shadows. | Beta |
| doIdleWork | undefined | boolean | To help prevent delays when a user interacts with a Viewport, the WebGL render system can precompile shader programs before any Viewport is opened. | Beta |
| dpiAwareLOD | undefined | boolean | If true, ScreenViewports will take into account the DPI of the display when computing the level of detail for tile graphics and decorations. | |
| dpiAwareViewports | undefined | boolean | If true, ScreenViewports will respect the DPI of the display. | |
| errorOnMissingUniform | undefined | boolean | If true, will cause exception when a shader uniform is missing (usually optimized out), otherwise will only log these. | |
| filterMapDrapeTextures | undefined | boolean | ###TODO this appears to do nothing. | |
| filterMapTextures | undefined | boolean | ###TODO this appears to do nothing. | |
| logarithmicDepthBuffer | undefined | boolean | If the view frustum is sufficiently large, and the EXT_frag_depth WebGL extension is available, use a logarithmic depth buffer to improve depth buffer resolution. | |
| planProjections | undefined | boolean | If true, plan projection models will be rendered using PlanProjectionSettings defined by the DisplayStyle3dState. | |
| preserveShaderSourceCode | undefined | boolean | If true, preserve the shader source code as internal strings, useful for debugging purposes. | |
| useWebGL2 | undefined | boolean | If true will attempt to create a WebGL2 context, falling back to WebGL1 if WebGL2 is not supported. |
