每一帧开始前,我们会先在drawInMTKView中调用updateGameState函数更新buffer的值。此处我们的Uniform Buffer只需要传递给顶点着色器,因此调用setVertexBuffer将buffer传递进去,buffer index为1。 Shaders.metal vertex ColorInOut vertexShader(Vertex in [[ stage_in ]], constant Uniforms & uniforms [[ buffer(1) ]...
对于PER_FRAME更新的buffer,The-Forge的示例中都使用了三缓冲轮换使用的方式,为了和The-Forge的习惯统一 Tex0和Tex1不会更新,所以texture的descriptorSet的更新频率是NONE cbuffer每帧刷新(不论prog和mixWeight的值是否发生修改),所以constantBuffer的descriptorSet更新频率为PER_FRAME 初始化uniformBlock buffer 添加UI,pr...
百度试题 结果1 题目constant buffer 可能啥意思?完整的句子是:Define constant buffers to store your uniform data.来自一篇DirectX 教程 相关知识点: 试题来源: 解析 常量数据缓冲区
cbuffer ModelViewProjectionConstantBuffer : register(b0) { matrix mvp; }; 请注意,必须为每个常量缓冲区声明一个寄存器。 不同的 Direct3D 功能级别可用的最大寄存器数有所不同,因此不要超过最低目标功能级别对应的最大数量。 将顶点属性移植到 Direct3D 输入布局和 HLSL 语义 ...
Unity有instancing的attribute array (uniform/constant buffer),通过InstanceID来访问每个instance的数据,实现每个实例的不同的参数(通常的一种做法). 然而Unreal没有这样的功能,只有一些instancing的vertex buffer. shader: #if USE_INSTANCING && !USE_INSTANCING_EMULATED float4...
So I am reading the vulkan book now and got a problem about the push Constant and ubo update. After I set up all the pipeline and descriptor stuff. Basically I just need the copy the buffer to the UBO buffer such as memcpy then I am done. Basically I can understand the issue about ...
In my opinion, 4 should be the fastest way, which is true in the test. Then 1 should be the next. Both 2 and 3 should be slower than 1. However, Neither 2 or 3 is slower than 1. In contrast, they are much faster than 1. Any ideas why using uniform buffer array slows down th...
