Rayve is probably the only general purpose game engine that doesn't have a rasterization pipeline.

Rasterization was invented long ago to flatten 3D scenes to 2D so that VGA hardware blitters could render a scene faster. OpenGL, DirectX and Vulkan are the direct evolution of rasterization.

Rasterization involves draw calls, frustum culling, occlusion culling, overdraw reduction, vertex / pixel processing, screen space projection, environment / cube mapping, forward / deferred rendering, transparency ordering, shadow mapping, depth buffers, filtering and more.

All this stuff isn't needed anymore.

Rayve replaces rasterization with a fully compute-based rendering pipeline built around deterministic ray tracing. Scenes objects are ray traced directly to the display buffer.

Deterministic ray tracing is Raylogic's own version of ray tracing. Some shortcuts are taken to make ray tracing fast and noise free. The visual tradeoffs are not typically important for games.

Many current game engines include ray tracing, but it's just for lighting related tasks. The core rendering pipeline remains rasterization-based.

Rayve is a C++ game engine that has a straighforward entity/component framework and API that makes writing games with Rayve fun. Rayve uses the smallest subset of C++ possible to keep things uncomplicated.

Rayve is code-centric and does not have a level editor. But importing entire levels with collision from a 3D modeling tool is very easy.

Rayve comes as a zip file that extracts to a folder. Double click on the Visual Studio solution and Rayve is ready to start creating games. Windows and Visual studio are required. A perpetual license is $35. Rayve is close sourced.

Raylogic is working on a space game "Dark Ore". Once complete, Rayve will be released along with the "Dark Ore" project for learning Rayve.
