Implementations

impl<'a> VaoBuilder<'a>

pub fn create_array_buffer<T: ArrayView>( self, program: &WebGlProgram, attribute: &str, size: i32, contents: &[T] ) -> Result<Self, JsValue>

Adds or modifies an array buffer to the VAO.

This function creates a WebGL2 buffer, fills it with the array contents, and associates it with the VAO being built or modified, associating it to a given attribute in a WebGL2 program.

pub fn create_element_array_buffer( self, contents: &[u16] ) -> Result<Self, JsValue>

Adds or modifies an element array buffer to the VAO.

This function creates a WebGL2 buffer, fills it with the array contents, and associates it with the VAO as an element array buffer.

pub fn build(self) -> Rc<WebGlVertexArrayObject>

Builds the VAO.

Finishes the construction of the VAO, returning the VAO object.
