Constructor & Destructor Documentation

GLArray()

GLArray::GLArray

(

)

Generate a VAO and bind it.

~GLArray()

GLArray::~GLArray

(

)

Destroy and delete the VAO name.

Member Function Documentation

bind()

void GLArray::bind

(

)

const

Bind this VAO for subsequent vertex specification/draws.

Here is the caller graph for this function:

connectIndexBuffer()

void GLArray::connectIndexBuffer

(

const GLBuffer &

buffer

)

const

Bind buffer as the index (element) buffer for this VAO.

Parameters

buffer

Buffer previously filled with indices (GLuint).

Here is the call graph for this function:

connectVertexAttrib()

void GLArray::connectVertexAttrib	(	const GLBuffer &	buffer,
		const GLProgram &	program,
		const std::string &	variable,
		size_t	elemCount,
		size_t	offset = 0,
		GLuint	divisor = 0 ) const

Connect a vertex attribute from a buffer to a program input.

Parameters

buffer	Source buffer holding interleaved attribute data.
program	Shader program from which to query the attribute location.
variable	Attribute identifier in the shader (e.g., "in_position").
elemCount	Components per vertex attribute (e.g., 2, 3, or 4).
offset	Offset (in elements, not bytes) from the start of each record.
divisor	Instance divisor (0 = per-vertex; >0 = per-instance).

Queries the attribute location from program and forwards the binding to GLBuffer::connectVertexAttrib() using the stride/element size derived from the most recent setData() on buffer.
