在上一篇文章中我们大概了解了SampleLit下的片元着色器主要干了什么。
Unity中URP下的SimpleLit片元着色器
我们在这篇文章中来看一下计算BlinnPhone光照时怎么获取主光的信息。 一、计算BulinnPhone的函数有两个重载
1、 目前最新使用的是该方法这是我们之后主要分析的函数 /// Phong lighting...half4 UniversalFragmentBlinnPhong(InputData inputData, SurfaceData surfaceData)
{#if defined(DEBUG_DISPLAY)half4 debugColor;if (CanDebugOverrideOutputColor(inputData, surfaceData, debugColor)){return debugColor;}#endifuint meshRenderingLayers GetMeshRenderingLayer();half4 shadowMask CalculateShadowMask(inputData);AmbientOcclusionFactor aoFactor CreateAmbientOcclusionFactor(inputData, surfaceData);Light mainLight GetMainLight(inputData, shadowMask, aoFactor);MixRealtimeAndBakedGI(mainLight, inputData.normalWS, inputData.bakedGI, aoFactor);inputData.bakedGI * surfaceData.albedo;LightingData lightingData CreateLightingData(inputData, surfaceData);
#ifdef _LIGHT_LAYERSif (IsMatchingLightLayer(mainLight.layerMask, meshRenderingLayers))
#endif{lightingData.mainLightColor CalculateBlinnPhong(mainLight, inputData, surfaceData);}#if defined(_ADDITIONAL_LIGHTS)uint pixelLightCount GetAdditionalLightsCount();#if USE_FORWARD_PLUSfor (uint lightIndex 0; lightIndex min(URP_FP_DIRECTIONAL_LIGHTS_COUNT, MAX_VISIBLE_LIGHTS); lightIndex){FORWARD_PLUS_SUBTRACTIVE_LIGHT_CHECKLight light GetAdditionalLight(lightIndex, inputData, shadowMask, aoFactor);
#ifdef _LIGHT_LAYERSif (IsMatchingLightLayer(light.layerMask, meshRenderingLayers))
#endif{lightingData.additionalLightsColor CalculateBlinnPhong(light, inputData, surfaceData);}}#endifLIGHT_LOOP_BEGIN(pixelLightCount)Light light GetAdditionalLight(lightIndex, inputData, shadowMask, aoFactor);
#ifdef _LIGHT_LAYERSif (IsMatchingLightLayer(light.layerMask, meshRenderingLayers))
#endif{lightingData.additionalLightsColor CalculateBlinnPhong(light, inputData, surfaceData);}LIGHT_LOOP_END#endif#if defined(_ADDITIONAL_LIGHTS_VERTEX)lightingData.vertexLightingColor inputData.vertexLighting * surfaceData.albedo;#endifreturn CalculateFinalColor(lightingData, surfaceData.alpha);
}2、 被淘汰的老方法需要传入一堆数据 二、GetMainLight
在 UniversalFragmentBlinnPhong 函数中一开始就获取了主光的信息这也是我们这篇文章中主要分析的怎么获取主光信息
1、Light结构体 其中最主要的就是
direction主光线方向color主光线颜色
2、GetMainLight具有4个方法重载 这里我们为了方便分析分别叫他们 1号、2号、3号、4号重载 带参数的方法重载额外实现了 阴影衰减 不带参数的方法重载 主要实现了主光信息的获取 BulinnPhone光照计算调用的是4号重载 我们按调用顺序依次展开分析 4号重载 调用了3号重载 3号重载 调用了 1号重载 2号 重载也调用了 1号重载但是我们这里没有使用到不做分析 1号重载该函数就是获取我们主光信息的函数
3、1号重载干了什么该函数就是获取我们主光信息的函数
_MainLightPosition 获取主光线方向 light.direction half3(_MainLightPosition.xyz); 我们输出看看效果
_MainLightColor 获取主光颜色 light.color _MainLightColor.rgb; 我们输出看看效果
unity_LightData.z 获取光照距离衰减值因为主光线是平行灯。所以没有距离远近的说法这里值只有 1 和 0 // unity_LightData.z is 1 when not culled by the culling mask, otherwise 0. //距离衰减接收光照时为 1。剔除接收光照为 0 light.distanceAttenuation unity_LightData.z; 阴影衰减预先赋值为 1后面再做处理 light.shadowAttenuation 1.0; 三、测试代码
