Detailed Description

Wraps an OpenGL Vertex Array Object.

Records the vertex attribute layout (which VBO feeds which shader input and how) so it can be rebound with a single call.

Constructor & Destructor Documentation

VAO()

cangine::VAO::VAO

(

)

Generates the underlying OpenGL vertex array object.

~VAO()

cangine::VAO::~VAO

(

)

Deletes the underlying OpenGL vertex array object.

Member Function Documentation

bind()

void cangine::VAO::bind

(

)

const

Binds this vertex array object.

linkAttrib()

void cangine::VAO::linkAttrib	(	const VBO &	vbo,
		unsigned int	layoutLocation,
		int	count,
		int	stride,
		uintptr_t	offset
	)

Links a vertex attribute from a VBO into this VAO.

Parameters

vbo	Buffer supplying the attribute data.
layoutLocation	Shader attribute location index.
count	Number of components per attribute (e.g. 3 for a vec3).
stride	Byte offset between consecutive attributes.
offset	Byte offset of the first component within the vertex.

unbind()

void cangine::VAO::unbind

(

)

const

Unbinds the current vertex array object.

Member Data Documentation

ID
