Detailed Description

A struct describing the name and type of each attribute designated as an instance attribute.

Constructor & Destructor Documentation

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

inline

Constructs a new instance attribute descriptor.

Parameters

name	The name of the attribute.
layoutLocation	The OpenGL attribute location of the attribute.
nComponents	The number of dimensions this attribute has, a multiplier on the storage size of type.
type	The actual OpenGL type of the attribute, like GL_FLOAT

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

inlinestaticprivate

Returns the size of a few known OpenGL component types, throws an error otherwise.

Parameters

type	The OpenGL type of the attribute component.

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

inline

Compares two vertex attributes for equality.

Parameters

other The attribute descriptor this one is being compared to.

Return values

true	Attributes are the same;
false	Attributes are different;
