In this lesson, you learn how to load textures into your DirectX 12 powered applications. You learn how to use the compute pipeline to generate mipmaps for textures. You also learn about texture samplers and how to specify a texture sampler in the root signature. A texture sampler is used to control how the texels are read in a shader.
In this tutorial, you will be introduced to several classes that will help you to create a robust and flexible framework for building DirectX 12 applications. Some of the problems that are solved with the classes introduced in this lesson are managing CPU descriptors, copying CPU descriptors to GPU visible descriptor heaps, managing resource state across multiple threads, and uploading dynamic buffer data to the GPU. To automatically manage the state and descriptors for resources, a custom command list class is also provided.
This is the second lesson in a series of lessons to teach you how to create a DirectX 12 powered application from scratch. In this lesson, vertex and index data is uploaded to the Graphics Processing Unit (GPU) for rendering. Basic vertex and pixel shaders are described and how to create a Pipeline State Object (PSO) that utilizes those shaders is also described. A root signature defines the parameters that are used by the stages of the rendering pipeline. In this lesson a simple root signature is created that defines a single constant buffer that contains the Model-View-Projection (MVP) matrix that is used to rotate a model in the scene.
This is the first lesson in a series of lessons to teach you how to create a DirectX 12 application from scratch. In this lesson, you will learn how to query for DirectX 12 capable display adapters that are available, create a DirectX 12 device, create a swap-chain, and you will also learn how to present the swap chain back buffer to the screen. In this lesson, you will also create a command queue and a command list and learn how to synchronize the CPU and GPU operations in order to correctly implement N-buffered rendering.
Visual Studio 2017 introduces the ability to open CMake projects directly in the Visual Studio development environment without the need to generate any project files first. In this tutorial, you will create a simple project that uses CMake to define the project configuration. You will also create several build configurations for the application. You will also create launch configurations to determine how the application is executed for debugging the application.
In this article, I will introduce the reader to CUDA 5.0. I will briefly talk about the architecture of the Kepler GPU (Graphics Processing Unit) and I will show you how you can take advantage of the many CUDA (Compute Unified Device Architecture) cores in the GPU to create massively parallel programs.
In this article, I will introduce you to the Unity game editor. Unity is a tool for creating and deploying games to PC, consoles, web and mobile devices. In this post, I will go through the steps to get Unity installed on your computer and I will introduce you to the basic features of Unity. Unity makes it easy for anyone to get started making games. You will not need any previous game development experience to follow these articles but by the end, you will be prepared to start making your own games like a professional!
In this article I will demonstrate how to implement a basic lighting model using the Cg shader language. If you are unfamiliar with using Cg in your own applications, then please refer to my previous article titled Introduction to Shader Programming with Cg 3.1.
This article is an updated version of the previous article titled Transformation and Lighting in Cg. In this article, I will not use any deprecated features of OpenGL. I will only use the core OpenGL 3.1 API.
