Struct ArrayBuffer 

pub struct ArrayBuffer { /* private fields */ }

Abstraction for an OpenGL array buffer.

This array buffer can hold a number of floating point components. It is set as a flat array, but should be thought of as a two dimensional array. The number of components is the number of columns in the array. The array buffer can be bound to several attribute locations, with each attribute location using one or more components.

Implementations

impl ArrayBuffer

pub fn new(components: u32) -> Self

Create an ArrayBuffer with a specified number of components.

pub fn len(&self) -> usize

Get the number of items in the array.

pub fn set_data(&mut self, vertices: Vec<f32>)

Set data.

The vertices array is a flat array, but should be thought of as a two dimensional array. The length of the ArrayBuffer will be the lenght of the array divided by the number of components.

pub fn bind(&self, attrib_location: i32, offs: usize, num: u32)

Bind array buffer to an attribute location.

The offs parameter specifies the first component to bind, and num specifies the number of compontns to bind.
