HLSL打包规则类似于使用Visual Studio执行pragma pack 4,它将数据打包成4字节的边界。此外,HLSL打包数据,使其不跨越16字节的边界。变量被压缩到一个给定的四分量向量中,直到变量跨越一个四分量边界;下一个变量将被放到下一个四分量向量。更详细的讨论:javascript:void(0) Direct3D 9与Direct3D 10和11之间的差异:...
这对宏定义通常与HLSL语法一起使用,用于定义一个具有特定数据结构的常量缓冲区。 在您提供的例子中,CBUFFER_START(UnityPerMaterial)表示一个名为 "UnityPerMaterial" 的常量缓冲区块的开始。其中定义了一个名为_BaseColor的数据成员,它是一个half4类型的变量(一个四分量的半精度浮点向量)。 常量缓冲区块的定义应...

原文转发: Shader Constants (DirectX HLSL) In shader model 4, shader constants are stored in one or more buffer resources in memory. They can be organized into two types of buffers: constant buffers (cbuffers) and texture buffers (tbuffers). Constant buffers are optimized for constant-variable ...

I generally use cbuffer with specifying 'b#' register in hlsl, but i recently found out it is fine that i don't have to specify it for some of cases. so it brings me a question. What exactly is the difference between cbuffer { float4x4 someMatrix = (float4x4)0; } And cbuffer...
D3D_CBF_USERPACKED值:1将常量缓冲区绑定到 HLSL 代码 (中定义的输入槽,而不是让编译器) 选择输入槽。 D3D10_CBF_USERPACKED将常量缓冲区绑定到 HLSL 代码 (中定义的输入槽,而不是让编译器) 选择输入槽。 D3D_CBF_FORCE_DWORD值: 0x7fffffff程序员不使用此值;它的存在是强制枚举编译为 32 位。注解...
