Other notes

Render order

• Culling by Andreas, includes spotlight shadows
• Deferred rendering for majority of models
• Render opaque models to spotlights shadowmap
• Tiled shading & culling point lights for forward+
• Spotlight shading (not yet tiled, it’s on my list)
• Sort for transparent objects
• Sort includes particles
• Particles are unlit (NYI lit particles)
• Lets particles be sorted properly with windows etc
• Forward+ pass for transparents & particles(Unlit)
• Post-processing
• Immediate Sprites & Text rendering
• ImGui & other debug overlays
• Present!

Current focus

One of the things I wanna focus on is transparent objects, I’ve had some fights with getting it right for our artists, I’ve been looking with one eye at different order independent transparency solutions and other approximations for a better result.
Another thing I want is faster spotlights and shadows, perhaps look closer at clustered or hybrid binning of lights and doing less in the deferred stage of rendering, it is rather bandwidth consuming, and I think an improved forward renderer could outshine our current default-to-deferred render order.
After all, the performance can never be too good and the quality is always lower than you want, constant pushing is required!

These third party libraries and technologies are used

There will be markings such as P6, P7 och P8 depending on what project that added it.

• (P6) DirectX11 for rendering
• (P6) entt as an entity component system
• (P6) assimp for model loading
• (P6) DirectXTK for .dds file loading and simplemath
• (P6) miniz-cpp for zipping crash logs for easy error reporting
• (P6) SoLoud for audio/sound
• (P6) NLohmanns json for modern C++ for json parsing/saving (simdjson can only read files, so still kept around)
• (P6) Dear ImGui for debugging tools
• (P6) ImGuizmo for tools and debugging purposes
• (P6 dropped in P7 in favor ov imgui-node-editor) imnodes
• (P7) physx for physics (since project 7)
• (P7) simdjson for quickly loading json files
• (P7) imgui-node-editor for tools
