Struct tray_rust::geometry::animated_mesh::AnimatedMesh

pub struct AnimatedMesh { /* fields omitted */ }

An animated mesh composed of a series of meshes linearly interpolated between over time. It's assumed the mesh topology does not change.

Methods

impl AnimatedMesh

pub fn new(meshes: Vec<Arc<Mesh>>, times: Vec<f32>) -> AnimatedMesh

Create a new AnimatedMesh from the meshes passed. It's assumed the meshes are sorted in ascending time

Trait Implementations

impl Geometry for AnimatedMesh

fn intersect(&self, ray: &mut Ray) -> Option<DifferentialGeometry>

Test a ray for intersection with the geometry. The ray should have been previously transformed into the geometry's object space otherwise the test will be incorrect. Returns the differential geometry containing the hit information if the ray hit the object and set's the ray's max_t member accordingly

impl Boundable for AnimatedMesh

fn bounds(&self, start: f32, end: f32) -> BBox

Get an AABB reporting the object's bounds over the time period The default implementation assumes the object isn't animated and simply returns its bounds. This is kind of a hack to use the BVH for animated geomtry (instances) and non-animated geometry (triangles).

fn update_deformation(&mut self, start: f32, end: f32)

Have the object recompute its bounds for the time range. In the case of deforming geometry this can rebuild acceleration structures for example.
