X2M water by 巨人网咯 2018
This document provides an overview and specifications for the X2M Water system asset. It describes the water surface effects including surface depth and color variation, reflection, refraction, and quality phases. The system uses Fresnel equations to vary color with distance from the camera and includes reflection, refraction, and caustics effects. It supports three quality phases for high, middle, and low profiles by adjusting reflection render target size, blur filtering, and enabling/disabling caustics effects.

- 2. OVERVIEW • Water surfacecolor variable according to camera angle of degree. • Used Depth read with Fresnel angular. • Remove to useless functions . • Removed to Foam effect. • Removed some unused lerp. • Only use to one of Normal texture. • Just piece of one normal texture sampler2D. • The piece of two texture parameter that created instance. • Make branching to three level of Quality Phases • Not used Multi compile then just adjusting quality phases setting to use X2M_Water script profiles.
- 3. SPECIFICATIONS OF WATERSURFACE EFFECTS • SURFACE DEPTH WITH DISTANCE Of COLOR ( FRESNEL ANGULAR VARIABLE COLOR EFFECT) 表面深度与颜色距离 • WATER REFLECTION / 水面反射 • WATER REFRACTION(DISTORTION) / 水面折射(扭曲) • WATER QUALITY PHASES / 质量阶段

- 5. SURFACE DEPTH WITHDISTANCE COLOR • 表面深度与颜色距离 ( FRESNEL ANGULAR VARIABLE COLOR EFFECT) Far distance Near distance
- 6. WAVE • 水面折射(扭曲) Distortion (Refraction ) : This function affect to under water mesh distortion as fragment to vertex.
- 7. SURFACE DEPTH WITHDISTANCE COLOR • 表面深度与颜色距离 ( FRESNEL ANGULAR VARIABLE COLOR EFFECT) Water Falloff : -0.05 Water Falloff : -1.34
- 8. SURFACE DEPTH WITHDISTANCE COLOR • 表面深度与颜色距离 ( FRESNEL ANGULAR VARIABLE COLOR EFFECT) Water Specular : If Water Specular value is higher that make blue water surface. Water Smoothness : If Water Smoothness value is higher that make tighten specular high-light on water surface.
- 9. REFLECTION • 水面反射 Reflection angle: Distortion directions of horizontal. Reflection Distort : Distortion wrap scale. (This property have related of effect with Distortion value.) Reflection Intensity : Reflection Power.
- 10. REFRACTION(DISTORTION) • 水面折射(扭曲) Distortion (Refraction ) : This function affect to under water mesh distortion as fragment to vertex.
- 11. QUALITY PHASES • 质量阶段 •HIGH PROFILE • Reflection RT size : 512 • Box blur Filter : 1 Caustics FX : Enable • MIDDLE PROFILE • Reflection RT size : 256 • Box blur Filter : 2 Caustics FX : Enable • LOW PROFILE • Reflection RT size : none • Box blur Filter : None • Caustics FX : Disable
Editor's Notes
- #3 카메라 각도에 따라서 변하는 물 표면 색상. Depth read 와 Fresnel angular 를 사용 하여 표현. 우리 게임 화면 표현을 검토 할 때 불필요 한 표현 제거. Foam effect 는 제거 하였다. 불필요 한 Lerp 함수 제거. 한 장의 Normal texture 사용. Normal texture sampler 1개 사용 함. 두 개의 texture parameter 생성은 sampler2D 를 instance 하여 사용. 3단계 Quality Phase 로 분기 Multi compile 사용 하지 않고 X2M_Water script 에서 프로필 관리.
