当我们有了一个uniform buff之后,vulkan 还不知道这个信息,需要通过descriptor进行描述. Descriptors and Descriptor Sets A descriptor is a special opaque shader variable(隐藏变量) that shaders use to access buffer and image resources in an indirect fashion. It can be thought of as a "…

DiligentEngine的API是D3d11和D3D12风格的,vulkan也被封装成了这种风格的API. 在了解Diligent Engine是如何对vulkan进行封装之前,我准备先学习下Vulkan.知乎funchun的编程指南是中文版,英文不好,准备先看一版中文版,回头再去研习其他的内容. 1.Vulkan编程指南阅读摘要 1.1 Vulkan SDK 安装完成之后,安装目录有如下文件.在阅读编程指南的过程中,我并未采用指南中的demo code来进行研究,而是使用的SDK自带的de…

上一篇 Vulkan SDK Demo 熟悉 粗略的了解了下,一个app是如何调用vulkan的api来展示一个立方体的,但是对其中的每一个api了解并不深刻,后面的系列会根据sample的tutorial Welcome to the Vulkan Samples Tutorial , 结合官方提供的教程来深入的进行学习,Lunar在github上有一个repo,Vulkan Samples, 本章要学习的是instance. Vulkan Samples需要设置msbuild和Camke的环…

A graphics pipeline consists of shader stages, a pipeline layout, a render pass, and fixed-function pipeline stages. Dynamic State A dynamic pipeline state is a state that can be changed by a command buffer command during the execution of a command b…

操作系统:Windows8.1 显卡:Nivida GTX965M 开发工具:Visual Studio 2017 Introduction 我们现在可以将任意属性传递给每个顶点的顶点着色器使用.但是全局变量呢?我们将会从本章开始介绍3D图形相关的内容,并需要一个模型视图投影矩阵.我们确实可以将它一顶点的方式包含,但是这非常浪费带宽.内存,并且需要我们在变换的时候更新顶点缓冲区的数据.这种变换通常发生在每一帧. 在Vulkan中正确处理此问题的途径是使用资源描述符.描述符是着色器资源访问诸如缓冲…

操作系统:Windows8.1 显卡:Nivida GTX965M 开发工具:Visual Studio 2017 Introduction 描述符布局描述了前一章节讨论过的可以绑定的描述符的类型.在本章节,我们创建描述符集,它将实际指定一个VkBuffer来绑定到一个uniform buffer描述符. Descriptor pool 描述符集合不能集合创建,它们必须像命令缓冲区一样,从对象池中分配使用.对于描述符集合相当于调用描述符对象池.我们将写一个新的函数createDescriptor…

The Vulkan Framebuffer Framebuffers represent a collection of memory attachments that are used by a render pass instance. Examples of these memory attachments include the color image buffers and depth buffer that we created in previous samples. A fra…

Compiling GLSL Shaders into SPIR-V 1.SPIR-V 是vulkan的底层shader语言.GLSL可以通过相关接口转换为SPIR-V. Creating Vulkan Shader Modules The Microsoft open source DXC compiler now supports Vulkan and DX12 backend code generation.  DXC, Microsoft’s open source HLSL compi…

Create a Render Pass A render pass describes the scope of a rendering operation by specifying the collection of attachments, subpasses, and dependencies used during the rendering operation. A render pass consists of at least one subpass. The communic…
