Struct RenderRecipe

pub struct RenderRecipe {
    pub matrices: Vec<Mat4>,
    pub primitives: Vec<Primitive>,
    pub matrix_for_primitives: Vec<usize>,
}

A RenderRecipe for a hierarchy of components

Created from a hierarchy of components, this is an array of transformation matrices, an array of Primitives, and an array of pairs (matrix index, primitive index) of what needs to be drawn

Fields

matrices: Vec<Mat4>

Matrices to use (the first is the identity matrix)

primitives: Vec<Primitive>

The primitives within the component

matrix_for_primitives: Vec<usize>

Draw requirements - matrix index for the associated primitive index

Implementations

impl RenderRecipe

pub fn new() -> Self

Create a new RenderRecipe

pub fn from_component_hierarchy(components: &Hierarchy<Component>) -> Self

Build a RenderRecipe from a Hierarchy of Component

It requires the hierarchy to have had ‘find_roots’ executed prior

Trait Implementations

impl Debug for RenderRecipe

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RenderRecipe

fn default() -> Self

Returns the “default value” for a type.
