void SetVertexShader(const ShaderPtr &shader)

Sets/returns the vertex shader stage.

Changes

Changes that affect the resource.

A ShaderProgram represents an OpenGL shader program that can be applied to shapes.

A Notifier both sends notifications to and receives notifications from other Notifiers.

const ShaderPtr & GetVertexShader() const

base::WeakReferentPtr< ShaderProgram > ShaderProgramWeakPtr

const ShaderPtr & GetFragmentShader() const

base::ReferentPtr< ShaderProgram >::Type ShaderProgramPtr

SharedPtr< ShaderInputRegistry > Type

const ShaderInputRegistryPtr & GetRegistry() const

Returns the ShaderInputRegistry used for the instance.

A Shader represents an OpenGL shader stage.

void SetFragmentShader(const ShaderPtr &shader)

Sets/returns the fragment shader stage.

base::ReferentPtr< ShaderInputRegistry >::Type ShaderInputRegistryPtr

Convenience typedef for shared pointer to a ShaderInputRegistry.

Base class for Shader and ShaderProgram objects.

bool IsConcurrent() const

A WeakReferentPtr is a weak reference to an instance of some class derived from Referent.
