Detailed Description

Class ModelVertexRenderer: Normal ModelRenderer implementations delegate vertex array management and vertex transformation to an implementation of ModelVertexRenderer.

ModelVertexRenderer implementations should be designed so that one instance of the implementation can be used with more than one ModelRenderer simultaneously.

◆ CreateModelData()

virtual CModelRData* ModelVertexRenderer::CreateModelData	(	const void *	key,
		CModel *	model
	)

pure virtual

CreateModelData: Create internal data for one model.

ModelRenderer implementations must call this once for every model that will later be rendered, with key set to a value that's unique to that ModelRenderer.

ModelVertexRenderer implementations should use this function to create per-CModel and per-CModelDef data like vertex arrays.

Parameters

key	An opaque pointer to pass to the CModelRData constructor
model	The model.

Returns: A new CModelRData that will be passed into other ModelVertexRenderer functions whenever the same CModel is used again.

Implemented in InstancingModelRenderer, and ShaderModelVertexRenderer.

◆ PrepareModelDef()

virtual void ModelVertexRenderer::PrepareModelDef	(	Renderer::Backend::IDeviceCommandContext *	deviceCommandContext,
		const CModelDef &	def
	)

pure virtual

PrepareModelDef: Setup backend state for rendering of models that use the given CModelDef object as base.

ModelRenderer implementations must call this function before rendering a sequence of models based on the given CModelDef. When a ModelRenderer switches back and forth between CModelDefs, it must call PrepareModelDef for every switch.

Parameters

def	The model definition.

Implemented in InstancingModelRenderer, and ShaderModelVertexRenderer.

◆ RenderModel()

virtual void ModelVertexRenderer::RenderModel	(	Renderer::Backend::IDeviceCommandContext *	deviceCommandContext,
		Renderer::Backend::IShaderProgram *	shader,
		CModel *	model,
		CModelRData *	data
	)

pure virtual

RenderModel: Invoke the rendering commands for the given model.

ModelRenderer implementations must call this function to perform the actual rendering.

preconditions : The most recent call to PrepareModelDef since BeginPass has been for model->GetModelDef().

Parameters

model	The model that should be rendered.
data	Private data for the model as returned by CreateModelData.

postconditions : Subsequent calls to RenderModel for models that use the same CModelDef object and the same texture must succeed.

Implemented in InstancingModelRenderer, and ShaderModelVertexRenderer.

◆ UpdateModelData()

virtual void ModelVertexRenderer::UpdateModelData	(	CModel *	model,
		CModelRData *	data,
		int	updateflags
	)

pure virtual

UpdateModelData: Calculate per-model data for each frame.

ModelRenderer implementations must call this once per frame for every model that is to be rendered in this frame, even if the value of updateflags will be zero. This implies that this function will also be called at least once between a call to CreateModelData and a call to RenderModel.

ModelVertexRenderer implementations should use this function to perform software vertex transforms and potentially other per-frame calculations.

Parameters

model	The model.
data	Private data as returned by CreateModelData.
updateflags	Flags indicating which data has changed during the frame. The value is the same as the value of the model's CRenderData::m_UpdateFlags.

Implemented in InstancingModelRenderer, and ShaderModelVertexRenderer.

◆ UploadModelData()

virtual void ModelVertexRenderer::UploadModelData	(	Renderer::Backend::IDeviceCommandContext *	deviceCommandContext,
		CModel *	model,
		CModelRData *	data
	)

pure virtual

Upload per-model data to backend.

ModelRenderer implementations must call this after UpdateModelData once per frame for every model that is to be rendered in this frame.

ModelVertexRenderer implementations should use this function to upload all needed data to backend.

Implemented in InstancingModelRenderer, and ShaderModelVertexRenderer.
