Struct three_d::renderer::geometry::Sprites

pub struct Sprites { /* private fields */ }

A set of sprites, ie. a set of quads that orients itself towards the camera. The sprites will always orient themselves towards the camera, but if a direction is specified, the sprite normals will also always be orthogonal to that direction. For example, if the up direction is specified, the sprites will rotate around the up direction trying to face the camera. Sprites are also known as billboards in the case where no direction is specified.

Implementations

impl Sprites

pub fn new(
    context: &Context,
    centers: &[Vec3],
    direction: Option<Vec3>
) -> ThreeDResult<Self>

Create a new set of Sprites with the given centers. The centers also determines the number of sprites. The sprites will always orient themselves towards the camera, but if a direction is specified, the sprite normals will always be orthogonal to that direction.

pub fn transformation(&self) -> Mat4

Returns the local to world transformation applied to all sprites.

pub fn set_transformation(&mut self, transformation: Mat4)

Set the local to world transformation applied to all sprites.

pub fn set_direction(&mut self, direction: Option<Vec3>)

Set a direction the sprite normals are always orthogonal to.

pub fn set_centers(&mut self, centers: &[Vec3]) -> ThreeDResult<()>

Set the centers of the sprites. The centers also determines the number of sprites.

Trait Implementations

impl Geometry for Sprites

fn render_with_material(
    &self,
    material: &dyn Material,
    camera: &Camera,
    lights: &[&dyn Light]
) -> ThreeDResult<()>

Render the geometry with the given material. Must be called in a render target render function, for example in the callback function of Screen::write. You can use an empty array for the lights argument, if you know the object does not require lights to be rendered.

fn aabb(&self) -> AxisAlignedBoundingBox

Returns the AxisAlignedBoundingBox for this geometry in the global coordinate system.
