Detailed Description

Render animated models using a ShaderRenderModifier.

This computes and binds per-vertex data; the modifier is responsible for setting any shader uniforms etc.

Member Function Documentation

void ShaderModelVertexRenderer::BeginPass ( int streamflags )

virtual

BeginPass: Setup global OpenGL state for this ModelVertexRenderer.

ModelVertexRenderer implementations should prepare "heavy" OpenGL state such as vertex shader state to prepare for rendering models and delivering vertex data to the fragment stage as described by streamflags.

ModelRenderer implementations must call this function before any calls to other rendering related functions.

Recursive calls to BeginPass are not allowed, and every BeginPass is matched by a corresponding call to EndPass.

Parameters

streamflags Vertex streams required by the fragment stage.

Implements ModelVertexRenderer.

Definition at line 232 of file HWLightingModelRenderer.cpp.

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

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.

Implements ModelVertexRenderer.

Definition at line 129 of file HWLightingModelRenderer.cpp.

void ShaderModelVertexRenderer::EndPass ( int streamflags )

virtual

EndPass: Cleanup OpenGL state set up by BeginPass.

ModelRenderer implementations must call this function after rendering related functions for one pass have been called.

Parameters

streamflags Vertex streams required by the fragment stage. This equals the streamflags parameter passed on the last call to BeginPass.

Implements ModelVertexRenderer.

Definition at line 241 of file HWLightingModelRenderer.cpp.

void ShaderModelVertexRenderer::PrepareModelDef	(	const CShaderProgramPtr &	shader,
		int	streamflags,
		const CModelDef &	def
	)

virtual

PrepareModelDef: Setup OpenGL 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

streamflags	Vertex streams required by the fragment stage. This equals the streamflags parameter passed on the last call to BeginPass.
def	The model definition.

Implements ModelVertexRenderer.

Definition at line 248 of file HWLightingModelRenderer.cpp.

void ShaderModelVertexRenderer::RenderModel	(	const CShaderProgramPtr &	shader,
		int	streamflags,
		CModel *	model,
		CModelRData *	data
	)

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

streamflags	Vertex streams required by the fragment stage. This equals the streamflags parameter passed on the last call to BeginPass.
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.

Implements ModelVertexRenderer.

Definition at line 265 of file HWLightingModelRenderer.cpp.

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

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.

Implements ModelVertexRenderer.
