Detailed Description

Central repository for resources.

The ResourceManager maintains a repository of all resources (materials, shaders, geometries) and is the only class able to create new resources. The main purpose of the ResourceManager is to act as a point of coordination for sharing resources.

Some notes on memory management:

• All resources are managed using shared pointers.
• The ResourceManager itself maintains a weak reference to each resource.
• If you create a resource (e.g., with MakeMaterial()) and do not retain the pointer, it gets immediately destroyed.

Member Function Documentation

GeometryResource::Ptr sv::ResourceManager::GetGeometry

(

const QString &

name

)

Retrieve the specified geometry.

If the geometry isn't found, then an empty pointer is returned.

MaterialResource::Ptr sv::ResourceManager::GetMaterial

(

const QString &

name

)

Retrieve the specified material.

If the material isn't found, then an empty pointer is returned.

ShaderResource::Ptr sv::ResourceManager::GetShader

(

const QString &

name

)

Retrieve the specified shader.

If the shader isn't found, then an empty pointer is returned.

GeometryResource::Ptr sv::ResourceManager::MakeGeometry

(

const QString &

name = kAutoName

)

Create a new geometry.

Exceptions

std::invalid_argument

If a resource with the same name already exists.

MaterialResource::Ptr sv::ResourceManager::MakeMaterial	(	const ShaderResource::Ptr &	shader,
		const QString &	name = kAutoName
	)

Create a new material.

Parameters

shader

the shader for the material to use.

Exceptions

std::invalid_argument

If a resource with the same name already exists.

Scene::Ptr sv::ResourceManager::MakeScene

(

const QString &

name = kAutoName

)

Create a new scene graph.

Exceptions

std::invalid_argument

If a resource with the same name already exists.

ShaderResource::Ptr sv::ResourceManager::MakeShader

(

const QString &

name = kAutoName

)

Create a new shader.

Exceptions

std::invalid_argument

If a resource with the same name already exists.
