Member Function Documentation

addVertexAttribute()

void BARE2D::VAO::addVertexAttribute	(	GLint	size,
		GLenum	type,
		GLboolean	normalized,
		GLsizei	stride,
		const void *	data
	)

Wrapper for glVertexAttribPointer - Adds an attribute to the VBO - each vertex data slot will gain some attribute.

Parameters

size	Number of components per attribute (1-4)
type	Type of data - GL_BYTE, GL_UNSIGNED_BYTE, GL_SHORT, etc. See docs
normalized	Should the data be normalized or converted directly? (GL_TRUE/GL_FALSE)
stride	Specifies the byte offset between consecutive generic vertex attributes. If stride is 0, the generic vertex attributes are understood to be tightly packed in the array. The initial value is 0.
data	Specifies a offset of the first component of the first generic vertex attribute in the array in the data store of the buffer currently bound to the GL_ARRAY_BUFFER target. The initial value is 0.
