If a null pointer is passed for materialId, coordsys, xform or attributes then that specific property set will remain unmodified. Thus, ModifyGeometryInstance()(groupId, instanceId, nullptr, nullptr, nullptr, nullptr) has no side-effects.

Parameters

[in]	groupPrototypeId	Identifies the geometry prototype group in which the instance currently belongs. May be GeometryPrototypeId::k_InvalidId, signifying the instance belongs to no group.
[in]	instanceId	The geometry instance handle that will be modified.
[in]	materialId	If non-null, specifies a new material to be assigned to the geometry instance.
[in]	coordsysList
[in]	xform	If non-null, assigns a new object to world transform for the instance.
[in]	attributes	If non-null, specifies a new attribute set for the geometry instance. It is expected that if provided, the attributes are a complete description, as it will completely overwrite the existing set of attributes.

Returns: A GeometryInstanceResult value. If k_Error is returned, the instance was not successfully modified. If k_Success is returned, the instance was successfully modified. If k_ResendPrimVars is returned, the instance was successfully modified; in addition, the caller should immediately issue a ModifyGeometryPrototype() for all associated geometry prototypes.

◆ ModifyGeometryPrototype()

Parameters

[in]	type	The type of the geometry.
[in]	geoPrototypeId	The geometry prototype that will be modified.

[in]	primvars	If non-null, specifies a new set of primvars for the geometry prototype. It is expected that if provided, the primvars are a complete description, as it will completely overwrite the existing set of primvars.

Returns: A GeometryPrototypeResult value. If k_Error is returned, the geometry prototype was not successfully modified. If k_Success is returned, the geometry prototype was successfully modified. If k_ResendPrimVars is returned, the geometry prototype properties were successfully modified; in addition, the caller should immediately reissue the ModifyGeometryPrototype() call, and include the full primvars for the prototype.

◆ Render()

virtual void Riley::Render	(	RenderViewList const &	renderViews,

pure virtual

Rendering Process APIs.

The following APIs are used to manipulate a rendering process started by calling Render():

stop the currently running render
modify properties of the currently running render
modify the metadata associated with existing riley entities.

Editing rendering process options and/or entity metadata does not affect the contents of the render outputs (i.e. framebuffer contents).Renders one or more views of a scene. Render() will run to completion unless:

it is stopped by an external signal
the application indicates it would like to edit the scene by calling Stop() (blocking) or RequestUpdate() (non-blocking)
the render call is configured to return after a fixed interval specified in either iterations or time (e.g. checkpointing)

Parameters

[in]

renderOptions

Render options shared by all render views. These options may change for each Render() call. Currently supported:

"renderMode" (string):
- "batch": The render will be optimized for best offline rendering performance.
- "interactive" : The render is expected to be interrupted for edits and will be optimized for interactive responsiveness.

◆ RequestUpdate()

virtual StopResult Riley::RequestUpdate ( )

pure virtual

Requests the renderer to stop.

This call is non-blocking. The Render() call will return at some later time when the renderer is ready to synchronize scene edits.

Returns: riley::StopResult::k_Success if the renderer was rendering riley::StopResult::k_NotRendering otherwise

◆ SetDefaultDicingCamera()

virtual void Riley::SetDefaultDicingCamera ( CameraId cameraId )

pure virtual

Sets the specified camera as active.

Parameters

[in] cameraId Identifies the default camera to be used for dicing. Providing an id that has not been returned from CreateCamera(), or deleting a camera that has already been deleted, results in undefined behavior.

◆ SetOptions()

virtual void Riley::SetOptions ( RtParamList const & sceneOptions )

pure virtual

Scene Manipulation APIs.

The following APIs are used to provide and/or modify the scene description. They can only be called during the editing phase (i.e. when Render() is not running).

Editing the scene description is expected to affect the render outputs.Sets the scene options. These are options that are part of the scene description, and may affect the render outputs.

Parameters

[in] sceneOptions Scene Options.

◆ Stop()

virtual StopResult Riley::Stop ( )
