Hardware 3D (C++ DirectX Graphics) Tutorial 46

In this video we explore the concept and theory of fullscreen (screen space) filter passes. We learn a little signal processing theory vis-a-vis convolutions, develop some code for managing offscreen render targets, and implement a couple of simple shaders for fullscreen filter effects.

Topics Covered

• Flaws in the Scale Outline and Offset Outline techniques
• One dimensional signal processing convolution
• Two dimensional discrete convolution for image processing
• RenderTarget and DepthStencil classes
• GraphicsResource base class refactor
• Textured quad screen space rendering technique
• Negative effect filter shader
• texture.GetDimension HLSL function
• HLSL for loop
• Mapping from pixels to texture coordinates for full screen filters
