创建缓冲区:使用vkCreateBuffer函数创建一个Vulkan缓冲区对象,指定其用途为VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT。 分配内存:为创建的缓冲区分配内存,并使用vkBindBufferMemory函数将内存绑定到缓冲区上。通常,会选择具有VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT和VK_MEMORY_PROPERTY_HOST_COHERENT_BIT属性的内存,以便CPU能够...

1- If I define the array of 5 structures as a uniform buffer array, the rendering takes 5ms (measured by Nsight Graphics). The uniform buffer's memory property is 'VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT | VK_MEMORY_PROPERTY_HOST_COHERENT_BIT'. The uniform buffer in glsl is defined as follo...
Creating the buffer is the same as creating any other uniform buffer object: vulkanDevice->createBuffer( VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT, VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT, &uniformBuffers.dynamic, bufferSize); (Updates will be flushed manually, the VK_MEMORY_PROPERTY_HOST_COHERENT_BIT flag...
初始化uniformBlock buffer 添加UI,prog添加下拉菜单,mixWeight添加滑条 descriptorSet是dx12/vulkan中非常重要的概念,为了后续学习,轻一定要理解透彻,descriptorSet本地相关的一些资料已经添加到文末参考中 在init函数中生成的对象别忘了在exit函数中删除,不然就内存泄漏了 ...

For mat2x2, the stride between columns is 16 bytes in In a uniform buffer and 8 bytes in storage buffer. As part of the resolution to #922, we decided to avoid having the user tell us the matrix stride. Then consider code like this: [[bl...
HLSL中，使用索引从数组如texture array或StructuredBuffer中获取数据时，可能遇到NonUniformResourceIndex问题。这个情况发生在同一个wave的不同thread中，索引值可能不同。此时，需要使用NonUniformResourceIndex关键字。问题在于，即使未正确使用该关键字，编译器可能不会给出警告。这种错误用法在硬件层面上可能...
