Directional Derivatives of Oblique Reflection Maps
Given an oblique reflection map Γ and functions ψ, χ ∈ Dlim (the space of R -valued functions that have finite left and right limits at every point), the directional derivative ∇χΓ(ψ) of Γ along χ, evaluated at ψ, is defined to be the pointwise limit, as ε ↓ 0, of the family of functions ∇εχΓ(ψ) . = ε [Γ(ψ + εχ) − Γ(ψ)]. Directional derivatives are shown to exist and lie in Dlim for oblique ref...
متن کاملPlausible Blinn-Phong Reflection of Standard Cube MIP-Maps
We describe the technique used in the G3D Innovation Engine 9.00 to produce reasonable real-time environment lighting. It adds two lines of code to a pixel shader to reasonably approximate Lambertian and Blinn-Phong glossy reflection of a standard cube map environment with a MIP-chain without preprocessing. That is, we combine Blinn’s BSDF with Blinn’s environment mapping in a modern physically...
متن کاملApproximation of Glossy Reflection with Prefiltered Environment Maps
A method is presented that can render glossy reflections with arbitrary isotropic bidirectional reflectance distribution functions (BRDFs) at interactive rates using texture mapping. This method is based on the well-known environment map technique for specular reflections. Our approach uses a singleor multilobe representation of bidirectional reflectance distribution functions, where the shape ...
متن کاملAn Algebraic Characterization of Vacuum States in Minkowski Space. III. Reflection Maps
Employing the algebraic framework of local quantum physics,vacuum states in Minkowski space are distinguished by a property of geometric modular action. This property allows one to construct from any locally generated net of observables and corresponding state a continuous unitary representation of the proper Poincaré group which acts covariantly on the net and leaves the state invariant. The p...
متن کاملConstant-psi constant-delta contour maps: applications to ellipsometry and to reflection-type optical devices.
Constant-psi constant-delta contour maps in the reduced angle-of-incidence-film-thickness plane that are useful in ellipsometry and in design of reflection-type optical devices are discussed. As a specific example, a contour map is given for the SiO(2)-Si film-substrate system at the 6328-A He-Ne laser wavelength.
