GDC 2011 - Direct 3D 11: Symbolic Derivatives and HLSL

  • Published:
  • Version: 1.0
  • Language: English

This presentation explains potential usage scenarios for the new Symbolid Derivative operator introduced in D3D 11.

In June 2010, the Microsoft DirectX SDK release included a new High Level Shading Language (HLSL) feature enabling the compiler to auto-magically generate derivative computations of functions. The new Symbolic Derivative operator F’() helps developers reduce authoring and maintenance pain for advanced shader creation using the HLSL compiler. Applications include computation of line and surface tangents, surface normals, surface curvature, Jacobians of texture to screen space mappings, velocities, accelerations, and more. Come, dust off your calculus books and learn how to wield this powerful tool on your GPU today in many exciting ways.
