	Types of scenes
	Three types of scene have been identified to evaluate the raytracer: Regression scenes - very small scenes to test code correctness (results) Concept scenes - handpicked scenes to test and measure specific characteristics (results) Real case scenes - real works case (results)

Regression Scenes

Those should be as small/fast as possible and test each feature of raycode.

• test249

	Tests instances support and mirror rays
	Tests mirror rays, blurry and exact, it's also possible to see a bug of shading code, that's performing exact mirror on the reflection of the right cube.
	Tests Ambient occlusion and area lamps, this scene also has very small polies that creates banding effect due to incorrect code handling neighbour faces
	Tests transparent shadows, and instance support
	Stresses instances and ray-mirrors

Concept Scenes

handpicked scenes to test and measure specific characteristics

Teapot in stadium

3943% faster 173% faster

A very small and highly detailed object inside a very low and large poly scene views a close view of the highly detailed mesh + low poly environ a close view of the highly detailed mesh + without low poly environ reason Should break octrees or other grids methods. Comparisons of how optimal the other methods are. files Balloon by macouno

Wire scene

224% faster 267% faster 197% faster

A scene where the probability of a ray hitting a mesh is very low, that means full of objects with holes. Probably a scene with a centered mirror object covered by many wire objects. views a curved mirror object (to break ray coherence) a flat mirror object (to take advantage of ray coherence) reason test full-space transverse (rays would need to transverse a big part of tree to get a hit result) test ray coherence files Strings and reflections by Shilam Wire and flat reflections by Shilam Wire and curved reflections by Shilam

Highly overlap scene

333% faster 298% faster

A scene where each primitive and each object BB's is higly overlapping others BB's. That would be like a large box with boxs inside with boxs inside with boxs inside... reason breaks bounding volumes files Interlinked cubic frames and a small render

Sub-linear test

177% faster

A really highly detailed scene views An overview of the whole scene An overview of a small part of the scene reason show that raytrace is performing well, render time should be similar on both views show that for large scenes the Zbuffer is the "slow" part files Vegetations and soil by Shilam Maybe this is covered by real cases

Axis aligned scenes

189% faster 255% faster

Architecture scene views a normal one and one with the scene rotated so that primitives aren't axis aligned reason test BB handling of axis aligned volumes files Any architecture scene? Strange building - Normal view by Shilam Strange building - Rotated view by Shilam

Shadow scene

262% faster 223% faster 228% faster 315% faster

A scene with large parts in total shadow of some lamps reason test any heuristics to lamp visibility files Shrubs in shadow by Shilam Shrubs in shadow - Ugly solid rocks by Shilam Shrubs in shadow - Ugly "surfaces-only" rocks by Shilam Large occlusion objects by Shilam
