The angle θ in degrees between two vectors can be found using:θ = acos(dot( V1, V2 ) / len( V1 ) * len( V2 ) ) * (180 / PI) See code Case 1:Current pixel is empty with a value N = (0,0,0) Do nothing. Case 2:Current pixel has the value N = (-1,0,0),...
GetVirtualShadowMapStaticArrayIndex():0;InterlockedMax(PassStruct.OutDepthBufferArray[uint3(pAddress,ArrayIndex)],asuint(DeviceZ));} 相关偏移的计算如下: uintCalcLevelOffsets(uintLevel){// VSM_LEVEL0_DIM_PAGES_XY is a power of two, so the footprint of each mip level MipSize_i=(VSM_LEVEL...
代码如下,视频测试案例是蓝图tick中调用,修改最后一个参数CaptureSource捕获不同的VisualizeBuffer voidUCaptureWorldBPLibrary::CaptureWorldTest(constUObject*WorldContextObject,UTextureRenderTarget2D*RenderTarget,floatFOV,FVectorInViewLocation,FRotatorInViewRotation,FNameCaptureSource){UWorld*World=WorldContextObject-...
Landscape Grass的CustomPin在Material的编译中在float GetGrassWeight0(){}这个函数中,这个函数的Compile就是输入到这个pin口的内容。 然后在LandscapeGrassWeight.usf中PSMain()会对这个函数进行采样。 他是一个SimpleMeshPass。 VS : FLandscapeGrassWeightVS ...
