Hardware 3D (C++ DirectX Graphics) Tutorial 24

In this tutorial we write our first non-trivial shader program--basic point light pixel shading with specular highlights. We take this opportunity to check out the functionality of the Graphics Debugger (it's pretty dope).

Topics Covered

Part 1

• Point light class with ImGui controls
• Single-color per-pixel diffuse shader
• Graphics Debugger
  • Examining pixel history
  • Stepping through shader code and inspecting variables
  • Inspecting CPU-side call stack corresponding to D3D events
  • Inspecting contents of constant buffers
  • Object history

Part 2

• Organizing constant buffers
  • Multiple constant buffer binding
• Specular highlights
• Constant buffer data alignment issues
• Graphics Debugger geometry inspection

Part 3

• Add final drawable (flat-shaded cone)
• Some fun times with ImGui (manipulating cube parameters)
