Custom HLSL tips

I’m not that experienced with shader development but needed to get an external shader working in UE4, without using a custom build of the engine. After banging my head against the wall for a few days, I got it all working. I’m posting a few things that

1.Mandelbulb algorithm (fractal)

Mandelbulb (wiki)는 2009년에 구면 좌표를 사용하여 Daniel White와 Paul Nylander가 구성한 3차원 프랙탈입니다.

# Maldelbrot set (wiki)

기반지식:

복소평면(가우스평면),

복소평면상에서 만델브로 집합(2차원) > 프렉탈 도형

만델벌브 알고리즘(3차원) >복소평면 사용불가

극좌표계 > xy좌표계 대신 점 P를 (r, Θ) (원점에서의 거리(변위),각도)로 표현.

(-r, Θ) = (r, Θ+π) = (-r, Θ+(2n+1)π). (r, Θ) = (r, Θ+2nπ).

편평한 판위에 가루를 뿌리고 진동을 주면 일정하게 생기는 무늬모양.

주파수가 높을수록 더 정교한 패턴이 생긴다.

3Dconnexion space navigator 포토샵 캔버스 회전 설정 방법 Tools2021. 5. 13. 00:50

space navigator에 포토샵 캔버스 회전 기능을 지원하지 않는다 :(

\Users\계정이름\AppData\Roaming\3Dconnexion\3DxWare\Cfg

폴더에서 photoshop.xml 편집.

포토샵의 canvas rotate는 rotate view tool (단축키 'R' hold) 기능으로 부드럽게 회전 시킬수 있다.

그리고 Alt+F13, Alt+F14 단축키로도 5도씩 회전 가능.

그렇지만 일반 키보드엔 F13,F14키가 없다.

그래서 매크로 기능이 있는 입력장치에서 사용 가능.

space navigator에서는 키 68,69 번이 F13, F14를 가르킴.

xml를 에디트해서 적용할때는 Stop 3Dxware / Start 3Dxware 재실행하면 된다.

예) 마우스 Z축 회전을 좌우로 나누어 적용.
