DirectX Model Renderer

Overview

This project demonstrates a complete DirectX 12 graphics pipeline through a simple 3D cube renderer. The implementation covers GPU initialization, resource setup, shader compilation, command recording, synchronization, and presentation. The demo includes an orbit camera, vertex-colored cube, a custom logging system, and an FPS counter shown in the window title.

Features

• Full DirectX 12 graphics pipeline setup (device, command queue, swap chain, descriptor heaps)
• Vertex and pixel shaders written in HLSL
• Vertex color interpolation for smooth gradients on the cube
• Orbit camera with basic mouse/keyboard controls
• Custom logger for categorized runtime messages (info, warn, error)
• Real-time FPS counter displayed in the window title
• Proper resource state transitions and GPU synchronization
• Simple, single-file demo structure suitable for learning and extension

Concepts Demonstrated

• Direct3D 12 device and command queue creation
• Swap chain and render target view setup
• Descriptor heap management (RTV/CBV/SRV as applicable)
• Creating and binding vertex and index buffers
• Constant buffer usage and updating (view/projection/model matrices)
• Compiling and binding HLSL shaders (vertex/pixel)
• Command list recording and executing
• Resource barriers and fence-based GPU synchronization
• Basic camera math (view and projection matrices)
• Basic performance tracking (frame timing and FPS)
