Gemino

Designed to be a high performance gpu-driven rendering engine with dynamic applications in mind (such as games).

It's also my passion project for learning and experimenting with new graphics programming concepts.

Goals

Milanote Board

• Fully "bindless" and GPU driven - Minimal CPU overhead
• Good performance for open worlds and indoor scenes
• Support for most desktop devices

Implemented Features

• Indirect draw with compute shader draw call generation (vkCmdDrawInstancedIndirectCount)
• Compute shader frustum culling
• Compute shader LOD system
• Handle and Range based resource management
• Transforms based on vec3, quat, vec3 instead of mat4 to save memory and lower computation time
• Per-frame Host to Device upload buffers designed to work well with frames in flight
• Compatible with all Vulkan 1.2 devices
• Simple parent<->children scene graph and scene management
• GLTF Import

Showcase

Early tests of Two-Pass Occlusion Culling and LODs:

Exactly 16'000'000 (400 x 100 x 400) monkeys and spheres.

(LODs don't work now because of the improvements made to the scenegraph mesh<->primitive relations. Occlusion culling is removed for now since this particular implementationt brings huge benefits only for little meshes so I'll bring it back if I implement Mesh Shading and understand it more)
