}
Expand description
A abstract representation of a index buffer
Example
let indices = vec![
0, 1, 3, // first Triangle
1, 2, 3, // second Triangle
];
// static
let ibo1 = VertexBuffer::new(calc_bytes_size(&indices) as isize, Some(&vertices));
// Dynamic
let ibo2 = VertexBuffer::new(calc_bytes_size(&indices) as isize);
// send half of the vertices
ibo2.send_data(24 / 2, 0, &indices);
Fields
id: u32
Implementations
sourceimpl IndexBuffer
impl IndexBuffer
sourcepub fn new(size: isize, indices: Option<&Vec<i32>>) -> Self
pub fn new(size: isize, indices: Option<&Vec<i32>>) -> Self
Return a IndexBuffer with the allocated size provided, the buffer data is static only if the indices isn’t None, else, the buffer data is dynamic
Arguments
size
- The size in bytes of the data to allocateindices
- A optional data to write
sourcepub fn send_data(&self, size: isize, offset: isize, indices: &Vec<i32>)
pub fn send_data(&self, size: isize, offset: isize, indices: &Vec<i32>)
Write data that wasn’t provided on the new function
Arguments
size
- The size in bytes of the data to writeoffset
- Point to a offset in the allocated spaceindices
- Data to write
pub fn bind(&self)
pub fn unbind(&self)
