float4 color = SAMPLE_TEXTURE2D(_Control1, sampler_Control1, uv + d.xy); color += SAMPLE_TEXTURE2D(_Control1, sampler_Control1, uv); color += SAMPLE_TEXTURE2D(_Control1, sampler_Control1, uv + d.zy); color += S
float depth = UNITY_SAMPLE_DEPTH(tex2Dproj(_CameraDepthTexture, UNITY_PROJ_COORD(i.screenPos))); 1. 其中,UNITY_SAMPLER_DEPTH是在HLSLSupport.cginc中定义的,用以获取r通道储存的深度值: // Deprecated; use SAMPLE_DEPTH_TEXTURE & SAMPLE_DEPTH_TEXTURE_PROJ instead #if defined(SHADER_API_PSP2) #...
float4 color = SAMPLE_TEXTURECUBE(textureName, sampler_textureName, dir); float4 color = SAMPLE_TEXTURECUBE_LOD(textureName, sampler_textureName, dir, lod); // uses 3D uv coord (named dir here, as it is typically a direction) // TextureCubeArray TEXTURECUBE_ARRAY(textureName); SAMPLER(s...
这里示范了 2种 手动lod模式 分别是 Grad采样 与直接计算lod. 实际dx11端游项目中,我更喜欢用Grad采样,unity某些版本的texture2DArray不带这个api,需要手动给 HLSLSupport.cginc 加入定义 #define UNITY_SAMPLE_TEX2DARRAY_GRAD(tex,coord,dx,dy) tex.SampleGrad (sampler##tex,coord,dx,dy) 三、采样器Point模式...
This makes the derivative wrong and the GPU will use the coarsest level of mipmap to sample the color because it thinks the texture is being projected to a really small area. This makes the color become grayish. The solution to it is to use tex2DGrad(texture, uv, ddx(uv), ddy(uv)...

sqrt 返回输入值的平方根。 step 返回(x >= a)? 1 : 0。 tan 返回输入值的正切值。 fanh 返回输入值的双曲线切线。 transpose 返回输入矩阵的转置。 tex1D* 1D纹理查询。 tex2D* 2D纹理查询。 tex3D* 3D纹理查询。 texCUBE* 立方纹理查询。
5.2.2 模型数据从哪里来,和01效果一样,只是多一步定义结构体获取模型数据 可以用UE4材质编辑器象征性还原一下,着色模型=无光照UE4已经为我们做好了大量的封装,这也是我需要学习unity代码的原因 Shader03_P105 // Upgrade NOTE: replaced 'mul(UNITY_MATRIX_MVP,*)' with 'UnityObjectToClipPos(*)' Shader "...
