Detailed Description

CRenderer handles the game-specific rendering tasks, relying on the base class to do all of the actual API-specific rendering.

Member Function Documentation

EndResourceUpload()

void CRenderer::EndResourceUpload ( )

private

Wait for the upload thread to terminate.

Here is the caller graph for this function:

GetD3DDevice()

ID3D12Device * CRenderer::GetD3DDevice

(

)

const

Reader function for the D3D device pointer.

Returns

the D3D device pointer.

GetExtents()

const Vector3 & CRenderer::GetExtents

(

const eModel

t

)

const

Reader function for the model extents (half width, height, and depth).

Parameters

t	Model type.

Returns

Const reference to the bounding box extents of a model of type t.

Here is the caller graph for this function:

GetPrimitiveDesc()

CMeshDesc * CRenderer::GetPrimitiveDesc

(

const eMesh

t

)

const

Get a pointer to the geometric primitive descriptor for a mesh type.

Parameters

t	Mesh type.

Returns

Pointer to the geometric primitive descriptor for the mesh type.

Here is the caller graph for this function:

Initialize()

void CRenderer::Initialize

(

)

Initialize the renderer, set the background color, and create a perspective camera.

Here is the caller graph for this function:

LoadGeometricPrimitives()

void CRenderer::LoadGeometricPrimitives

(

)

Load meshes, textures, and effects for geometric primitives.

Here is the call graph for this function:

Here is the caller graph for this function:

LoadModel()

void CRenderer::LoadModel	(	eModel	t,
		const std::wstring &	strPath )

Load a model mesh and texture from a file to the GPU.

Parameters

t	Model type.
strPath	Wide string containing path and file name.

Here is the caller graph for this function:

Render()

void CRenderer::Render

(

CObject *

pObj

)

Render an object.

Parameters

pObj	Pointer to the object to be rendered. May be nullptr.

Here is the call graph for this function:

Here is the caller graph for this function:

UploadBoxMesh()

void CRenderer::UploadBoxMesh ( CMeshDesc * pDesc )

private

Upload box mesh to GPU. This gets its own function because we will be repeating the texture across each face.

Parameters

pDesc

Pointer to geometric primitive descriptor.

Here is the caller graph for this function:

UploadDefaultEffect()

void CRenderer::UploadDefaultEffect ( CMeshDesc * pDesc )

private

Upload default effect to GPU.

Parameters

pDesc

Pointer to geometric primitive descriptor.

Here is the caller graph for this function:

UploadPrimitiveMesh()

void CRenderer::UploadPrimitiveMesh ( CMeshDesc * pDesc )

private

General function for uploading a geometric primitive mesh. Creates a new primitive mesh descriptor and fills it with mesh information including a local copy of vertices, and stores a pointer to it in m_vecPrimitives[t] for later use, for example, in physics calculations such as collision detection and response.

Parameters

pDesc

Pointer to geometric primitive descriptor.

Here is the caller graph for this function:

UploadSphereMesh()

void CRenderer::UploadSphereMesh ( CMeshDesc * pDesc )

private

Upload sphere mesh to GPU. The sphere gets its own function because it has its own level of triangulation, which will be larger for large spheres.

Parameters

pDesc

Pointer to geometric primitive descriptor.

Here is the caller graph for this function:

UploadTexture()

void CRenderer::UploadTexture ( char * name, eMesh t )

private

Upload texture to GPU.

Parameters

name	Name string found in gamesettings.xml.
t	Texture type.

Here is the caller graph for this function:
