Description

Classic Whitted-style ray-tracer. See [https://castle-engine.io/vrml_engine_doc/output/xsl/html/section.classic_ray_tracer.html] for documentation.

Make sure that VRML2Lights in states are properly initialized if you plan to render VRML 2.0 nodes. TCastleSceneCore and descendants do this for you automatically.

Description

Fields

	`InitialDepth: Cardinal;`
Limit for recursion depth. 0 means that only primary rays will be cast, 1 means that primary rays and 1 ray into mirror / transmitted / shadow, and so on.

	`FogNode: TFogNode;`
Fog to render. Set `FogNode` <> `Nil` to render a fog, following VRML 2.0/X3D lighting equations. FogNode.TransformScale is used.

	`GlobalLights: TLightInstancesList;`
Lights shining on everything, like a headlight.

	`OwnsGlobalLights: boolean;`

Methods

	`procedure AppendStats(const Stats: TStrings; const RenderingTime: Single); override;`
