ShaderLab cginc固定 Vector.forward 方向的球形透视根据镜头任意视角方向的球形透视添加开始弯曲透视的 z 距离偏移
CurveWorldControl.cs需要修改的代码ProjectReferences
我发现莉莉丝的《神觉者》在战斗中也有使用到这个效果，视觉效果提升还是很大的 比如，球形投影前的效果 球形投影后的效果 GIF: 参考： Shader in Unity & Curved world shader & Change material color 实现的效果 实现的只能是 Vector.forward 方向的球形投影 #ifndef __CURVE_WORLD_LIB_H__ #define __CURVE_WORLD_LIB_H__ // jave.lin 2023/02/01 curve world library #ifdef _CURVE_WORLD_ON uniform float _Curve_Depth; uniform float _Depth_Divider; void CurveWorldApply(inout float3 positionWS, out float3 positionOS) { float3 deltaVec = positionWS - _WorldSpaceCameraPos.xyz; float E = -_Curve_Depth * _Depth_Divider; float detlaVecZ2 = deltaVec.z * deltaVec.z; detlaVecZ2 *= E; float3 offset = float3(0.0, detlaVecZ2, 0.0); positionWS += offset; positionOS = mul(unity_WorldToObject, float4(positionWS, 1.0)).xyz; } #define CURVE_WORLD_APPLY(positionWS, positionOS) CurveWorldApply(positionWS, positionOS); #else #define CURVE_WORLD_APPLY(positionWS, positionOS) #endif #endif 根据镜头任意视角方向的球形透视 #ifndef __CURVE_WORLD_LIB_H__ #define __CURVE_WORLD_LIB_H__ // jave.lin 2023/02/01 curve world library #ifdef _CURVE_WORLD_ON uniform float _Curve_Depth; uniform float _Depth_Divider; //uniform int _CW_Enabled; uniform float4 _Cam_Forward; void CurveWorldApply(inout float3 positionWS, out float3 positionOS) { //float3 srcPosWS = positionWS; //float3 srcPosOS = positionOS; // jave.lin : zDist ref to : AutoLight.cginc float3 deltaVec = _WorldSpaceCameraPos - positionWS; //float zDist = dot(deltaVec, UNITY_MATRIX_V[2].xyz); float zDist = dot(deltaVec, _Cam_Forward.xyz); float E = -_Curve_Depth * _Depth_Divider; float zDist2 = zDist * zDist; zDist2 *= E; float3 offset = float3(0.0, zDist2, 0.0); positionWS += offset; positionOS = mul(unity_WorldToObject, float4(positionWS, 1.0)).xyz; //positionWS = lerp(srcPosWS, positionWS, _CW_Enabled); //positionOS = lerp(srcPosOS, positionOS, _CW_Enabled); } #define CURVE_WORLD_APPLY(positionWS, positionOS) CurveWorldApply(positionWS, positionOS); #else #define CURVE_WORLD_APPLY(positionWS, positionOS) #endif #endif 添加开始弯曲透视的 z 距离偏移留意： uniform float _Z_Dist_Offset; #ifndef __CURVE_WORLD_LIB_H__ #define __CURVE_WORLD_LIB_H__ // jave.lin 2023/02/01 curve world library #ifdef _CURVE_WORLD_ON uniform float _Curve_Depth; uniform float _Depth_Divider; //uniform int _CW_Enabled; uniform float4 _Cam_Forward; uniform float _Z_Dist_Offset; void CurveWorldApply(inout float3 positionWS, out float3 positionOS) { //float3 srcPosWS = positionWS; //float3 srcPosOS = positionOS; // jave.lin : zDist ref to : AutoLight.cginc float3 deltaVec = _WorldSpaceCameraPos - positionWS; //float zDist = dot(deltaVec, UNITY_MATRIX_V[2].xyz); float zDist = max(0, dot(deltaVec, _Cam_Forward.xyz) - _Z_Dist_Offset); float E = -_Curve_Depth * _Depth_Divider; float zDist2 = zDist * zDist; zDist2 *= E; float3 offset = float3(0.0, zDist2, 0.0); positionWS += offset; positionOS = mul(unity_WorldToObject, float4(positionWS, 1.0)).xyz; //positionWS = lerp(srcPosWS, positionWS, _CW_Enabled); //positionOS = lerp(srcPosOS, positionOS, _CW_Enabled); } #define CURVE_WORLD_APPLY(positionWS, positionOS) CurveWorldApply(positionWS, positionOS); #else #define CURVE_WORLD_APPLY(positionWS, positionOS) #endif #endif CurveWorldControl.cs // jave.lin : curve world control using UnityEngine; [ExecuteInEditMode] public class CurveWorldControl : MonoBehaviour { private bool _last_on = false; public bool on = true; [Range(0.005f, 1.0f)] public float curveDepth = 0.015f; public float depthDivider = 0.0f; public Camera cam; private static int _Curve_Depth = Shader.PropertyToID("_Curve_Depth"); private static int _Depth_Divider = Shader.PropertyToID("_Depth_Divider"); private static int _Cam_Forward = Shader.PropertyToID("_Cam_Forward"); private void Update() { if (cam == null) { Shader.DisableKeyword("_CURVE_WORLD_ON"); return; } if (_last_on != on) { if (on) { Shader.EnableKeyword("_CURVE_WORLD_ON"); } else { Shader.DisableKeyword("_CURVE_WORLD_ON"); } _last_on = on; } if (_last_on) { Shader.SetGlobalFloat(_Curve_Depth, curveDepth); Shader.SetGlobalFloat(_Depth_Divider, depthDivider); var view_forward = cam.worldToCameraMatrix.GetColumn(2); Shader.SetGlobalVector(_Cam_Forward, view_forward); } } } 需要修改的代码修改所有 3D shader 即可 pass添加代码： #pragma multi_compile _ _CURVE_WORLD_ON#include “CurveWorldLib.cginc”CURVE_WORLD_APPLY(posWorld.xyz, v.vertex.xyz) 要添加的pass ForwardBaseForwardAddShadowCaster CurveWorldControl.cs 的 DontDestryOnLoad对应场景才开启 CurveWorldControl ProjectTestingSphereProjectionEffect - 参考： Shader in Unity & Curved world shader & Change material color 实现的效果 References全部看完，相信你可以做一款很有意思的游戏，或是游戏中很有特色的效果 英文搜索关键字： 油管搜索关键字: curved-worldgoogle : curved-world Shader in Unity & Curved world shader & Change material colorMobile Optimized Curve Shader for Mobile Games || Universal Render Pipeline || Shader GraphCurved World shader bendingcurved world using vertex shaders, #threejs, #glslMaking of SHRINKING PLANET - Ludum Dare 38Make Awesome Curved Worlds!
