1. What does the Rendering Engine Need?

• Rendering Engine
  • Support for Multiple Graphics APIs : OpenGL | Vulkan | DirectX12 | DirectX11 | Metal
  • Content Export Pipeline : Create Maya/Max Plugins to export meshes based on Renderers needs. (Assimp Commercial Licence -> Pay)
  • Texture Compression Libraries
  • Material System : Artists Configure shaders, textures, parameters to import in game
  • Game-side Manager of Models/Materials/Lights
  • Good Visibility System (Frustum/Occlusion) (VisibilityBuffers?)
  • Multi-Threded Submission System to reduce cost of submission to GPU
• Lighting/Shadow Rendering System

Why I think Immediate Mode GUI is way to go for GameDev tools

Prerequisites

Before you continue, if you don't know what IMGUI is don't bother reading this post, just ignore it, don't write anything in comments section, etc. If you're curious about IMGUI see bottom of this post, otherwise continue whatever you were doing, this post it's not for you. Thanks!

If you know what IMGUI is, for context read following presentations and blog posts:

/*
2D Angle Interpolation (shortest distance)

Parameters:
a0 = start angle
a1 = end angle
t = interpolation factor (0.0=start, 1.0=end)

Benefits:
1. Angles do NOT need to be normalized.
