Scene class
#include <darts/scene.h>

Main scene data structure.

This class aggregates all the surfaces and materials along with the camera.

Base classes

void parse(const json& j): Parse a scene from a json object.
void add_child(shared_ptr<Surface> surface) override: Add a child surface.
auto intersect(const Ray3f& ray, HitInfo& hit) const -> bool override: Ray-Surface intersection test.
auto bounds() const -> Box3f override: Return the surface's world-space AABB.
auto background(const Ray3f& ray) const -> Color3f: Return the background color.
auto camera() const -> shared_ptr<const Camera>: Return the camera.
auto recursive_color(const Ray3f& ray, int depth) const -> Color3f: Sample the color along a ray.
auto raytrace() const -> Image3f: Generate the entire image by ray tracing.

Add a child surface.

This function will become useful once we create groups of objects. The base class implementation just throws an error.

This function should only be used before build() is called.

Ray-Surface intersection test.

Parameters
ray in	A 3-dimensional ray data structure with minimum/maximum extent information
hit out	A detailed intersection record, which will be filled by the intersection query
Returns	True if an intersection was found

Intersect a ray against this surface and return detailed intersection information.

Sample the color along a ray.

Parameters
ray	The ray in question
depth	The current recursion depth
Returns	An estimate of the color from this direction
