Member Function Documentation

◆ EndFrame()

void ShaderModelRenderer::EndFrame ( )

overridevirtual

EndFrame: Remove all models from the list of submitted models.

Implements ModelRenderer.

◆ PrepareModels()

void ShaderModelRenderer::PrepareModels ( )

overridevirtual

PrepareModels: Calculate renderer data for all previously submitted models.

Must be called before any rendering calls and after all models for this frame have been submitted.

Implements ModelRenderer.

◆ Render()

void ShaderModelRenderer::Render	(	Renderer::Backend::IDeviceCommandContext *	deviceCommandContext,
		const RenderModifierPtr &	modifier,
		const CShaderDefines &	context,
		int	cullGroup,
		int	flags
	)

overridevirtual

Render: Render submitted models, using the given RenderModifier to setup the fragment stage.

Note: It is suggested that derived model renderers implement and use this Render functions. However, a highly specialized model renderer may need to "disable" this function and provide its own Render function with a different prototype.

preconditions : PrepareModels must be called after all models have been submitted and before calling Render.

Parameters

modifier	The RenderModifier that specifies the fragment stage.
flags	If flags is 0, all submitted models are rendered. If flags is non-zero, only models that contain flags in their CModel::GetFlags() are rendered.

Implements ModelRenderer.

◆ Submit()

void ShaderModelRenderer::Submit	(	int	cullGroup,
		CModel *	model
	)

overridevirtual

Submit: Submit a model for rendering this frame.

preconditions : The model must not have been submitted to any ModelRenderer in this frame. Submit may only be called after EndFrame and before PrepareModels.

Parameters

model The model that will be added to the list of models submitted this frame.

Implements ModelRenderer.
