Detailed Description

Class ModelRenderer: Abstract base class for all model renders.

A ModelRenderer manages a per-frame list of models.

It is supposed to be derived in order to create new ways in which the per-frame list of models can be managed (for batching, for transparent rendering, etc.) or potentially for rarely used special effects.

A typical ModelRenderer will delegate vertex transformation/setup to a ModelVertexRenderer. It will delegate fragment stage setup to a RenderModifier.

For most purposes, you should use a BatchModelRenderer with specialized ModelVertexRenderer and RenderModifier implementations.

It is suggested that a derived class implement the provided generic Render function, however in some cases it may be necessary to supply a Render function with a different prototype.

ModelRenderer also contains a number of static helper functions for building vertex arrays.

void ModelRenderer::BuildColor4ub	(	CModel *	model,
		const VertexArrayIterator< CVector3D > &	Normal,
		const VertexArrayIterator< SColor4ub > &	Color
	)

static

BuildColor4ub: Build lighting colors for the given model, based on previously calculated world space normals.

Parameters

model	The model that is to be lit.
Normal	Array of the model's normal vectors, animated and transformed into world space.
Color	Points to the array that will receive the lit vertex color. The array behind the iterator must large enough to hold model->GetModelDef()->GetNumVertices() vertices.

void ModelRenderer::BuildIndices	(	const CModelDefPtr &	mdef,
		const VertexArrayIterator< u16 > &	Indices
	)

static

BuildIndices: Create the indices array for the given CModelDef.

Parameters

mdef	The model definition object.
Indices	The index array, must be able to hold mdef->GetNumFaces()*3 elements.

void ModelRenderer::BuildPositionAndNormals	(	CModel *	model,
		const VertexArrayIterator< CVector3D > &	Position,
		const VertexArrayIterator< CVector3D > &	Normal
	)

static

BuildPositionAndNormals: Build animated vertices and normals, transformed into world space.

Parameters

model	The model that is to be transformed.
Position	Points to the array that will receive transformed position vectors. The array behind the iterator must be large enough to hold model->GetModelDef()->GetNumVertices() vertices. It must allow 16 bytes to be written to each element (i.e. provide 4 bytes of padding after each CVector3D).
Normal	Points to the array that will receive transformed normal vectors. The array behind the iterator must be as large as the Position array.

void ModelRenderer::BuildUV	(	const CModelDefPtr &	mdef,
		const VertexArrayIterator< float[2]> &	UV,
		int	UVset
	)

static

BuildUV: Copy UV coordinates into the given vertex array.

Parameters

mdef	The model def.
UV	Points to the array that will receive UV coordinates. The array behind the iterator must large enough to hold mdef->GetNumVertices() vertices.

void ModelRenderer::CopyPositionAndNormals	(	const CModelDefPtr &	mdef,
		const VertexArrayIterator< CVector3D > &	Position,
		const VertexArrayIterator< CVector3D > &	Normal
	)

static

CopyPositionAndNormals: Copy unanimated object-space vertices and normals into the given vertex array.

Parameters

mdef	The underlying CModelDef that contains mesh data.
Position	Points to the array that will receive position vectors. The array behind the iterator must be large enough to hold model->GetModelDef()->GetNumVertices() vertices.
Normal	Points to the array that will receive normal vectors. The array behind the iterator must be as large as the Position array.

virtual void ModelRenderer::EndFrame ( )

pure virtual

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

Implemented in ShaderModelRenderer.

void ModelRenderer::GenTangents	(	const CModelDefPtr &	mdef,
		std::vector< float > &	newVertices,
		bool	gpuSkinning
	)

static

GenTangents: Generate tangents for the given CModelDef.

Parameters

mdef	The model definition object.
newVertices	An out vector of the unindexed vertices with tangents added. The new vertices cannot be used with existing face index and must be welded/reindexed.

void ModelRenderer::Init ( )

static

Initialise global settings.

Should be called before using the class.

virtual void ModelRenderer::PrepareModels ( )

pure virtual

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.

Implemented in ShaderModelRenderer.

virtual void ModelRenderer::Render	(	const RenderModifierPtr &	modifier,
		const CShaderDefines &	context,
		int	cullGroup,
		int	flags
	)

pure virtual

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.

Implemented in ShaderModelRenderer.

virtual void ModelRenderer::Submit	(	int	cullGroup,
		CModel *	model
	)

pure virtual

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.

Implemented in ShaderModelRenderer.
