This is probably the world's first game with entire ray tracing rendering technology.

Build your dream world with simple cubes and spheres, using different materials like diffuse, glossy and glass, place the colorful light wherever you want. You will see the accurate lights and shadows, reflections and refractions, just like in the real world. The very high performance ray tracing and denoise implementation make this happen in nearly real time.

You don't need any special device to run this App, RtBuilder can do real time ray tracing using CPU or GPU, even the Intel integrated GPU is supported.

Key features:
-Environment Lights: Area light, Noon, Morning, Overcast, Night.
-Cubes and sphere shapes. Massive objects supported, the App will run at 80% FPS when you add 1 Million objects in the scene compare to an empty scene.
-Materials: Diffuse, Glossy, Glass, Emission, Diffuse-Glossy, Rough-Glass.
-Textures: A few internal textures and you can add your own textures. (Click File=>Custom Texture Folder, copy and paste your image there and then restart App. You can add 32 textures at most with current version.)
-Camera Mode: Observer and First Person.
-Ray Tracing Device: CPU and GPU.

Enjoy the gorgeous graphics!
