만화적 표현은 크게 2가지 특징이 있다. 첫째로 외곽선 표현하는 것이고, 둘째로는 명암처리를 날카롭게 표현하는 것이다.
일단은 외곽선을 생성한다.
위 결과물의 특징은 경계쪽의 Frequency가 급격히 변화한다는 것이다.
이에 HPF(High Pass Filter)를 적용하면 외곽선 추출을 손쉽게 얻어낼 수 있다.
최종 결과물을 만들기 위해 위에서 만들어진 두 결과물을 합성한다.
합성할 때에는 Multiply기법을 사용하면 된다. (두 픽셀값을 곱하여 값을 얻어오는 방식)
//**************************************************************//
// Effect File exported by RenderMonkey 1.6
//
// - Although many improvements were made to RenderMonkey FX
// file export, there are still situations that may cause
// compilation problems once the file is exported, such as
// occasional naming conflicts for methods, since FX format
// does not support any notions of name spaces. You need to
// try to create workspaces in such a way as to minimize
// potential naming conflicts on export.
//
// - Note that to minimize resulting name collisions in the FX
// file, RenderMonkey will mangle names for passes, shaders
// and function names as necessary to reduce name conflicts.
