Struct three_d::core::buffer::ElementBuffer

pub struct ElementBuffer { /* private fields */ }

A buffer containing 3 indices for each triangle to be rendered, which is why it is also known as an index buffer. The three indices refer to three places in a set of VertexBuffer where the data (position, normal etc.) is found for the three vertices of the triangle. See for example Program::draw_elements to use this for drawing.

Implementations

impl ElementBuffer

pub fn new(context: &Context) -> ThreeDResult<Self>

Creates a new empty element buffer.

pub fn new_with_data<T: ElementBufferDataType>(
    context: &Context,
    data: &[T]
) -> ThreeDResult<Self>

Creates a new element buffer and fills it with the given indices which must be divisable by 3.

pub fn new_with<T: ElementBufferDataType>(
    context: &Context,
    data: &[T]
) -> ThreeDResult<Self>

👎 Deprecated:

use new_with_data()

Creates a new element buffer and fills it with the given indices which must be divisable by 3.

pub fn fill<T: ElementBufferDataType>(&mut self, data: &[T]) -> ThreeDResult<()>

Fills the buffer with the given indices which must be divisable by 3.

pub fn fill_with<T: ElementBufferDataType>(
    &mut self,
    data: &[T]
) -> ThreeDResult<()>

👎 Deprecated:

use fill()

Fills the buffer with the given indices which must be divisable by 3.

pub fn count(&self) -> usize

The number of values in the buffer.

pub fn triangle_count(&self) -> usize

The number of triangles in the buffer.
