Detailed Description

The description of a single vertex attribute associated with a vertex layout, giving its size and location id.

Constructor & Destructor Documentation

ToyMaker::VertexAttributeDescriptor::VertexAttributeDescriptor	(	const std::string &	name,
		GLint	layoutLocation,
		GLuint	nComponents = 1,
		GLenum	type = GL_FLOAT )

inline

Creates a single vertex attribute descriptor.

Parameters

name	The name of the attribute, as seen by the shader.
layoutLocation	The location ID of the attribute, as specified by the shader.
nComponents	The number of components making up this attribute.
type	The type of a single component of the attribute (like GL_FLOAT, GL_UNSIGNED_BYTE, and so on).

static std::size_t ToyMaker::VertexAttributeDescriptor::GetGLTypeSize ( GLenum type )

inlinestaticprivate

Gets the size of the type of a single component of an attribute.

Parameters

type	The GLenum of the component type.

bool ToyMaker::VertexAttributeDescriptor::operator== ( const VertexAttributeDescriptor & other ) const

inline

Compares two vertex attribute descriptors for equality.

Mainly used to determine whether the vertex layout requested by a render stage matches the vertex layout associated with some vertex data.

Parameters

other The vertex descriptor this one is being compared to.

Return values

true	The other description matches this one.
false	The other description does not match this one.

std::size_t ToyMaker::VertexAttributeDescriptor::mSize

The computed size of the attribute, in bytes.

Given by : size of mType * mNComponents
