Rendering Engine Development

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

Efficient matrix multiplication

High-Performance Matrix Multiplication

This is a short post that explains how to write a high-performance matrix multiplication program on modern processors. In this tutorial I will use a single core of the Skylake-client CPU with AVX2, but the principles in this post also apply to other processors with different instruction sets (such as AVX512).

Intro

Matrix multiplication is a mathematical operation that defines the product of
