About This Book
- Learn and enforce the complex rendering ideas in Direct3D 11.2 and convey your 3D photos undertaking to life
- Study the resource code and electronic resources with a small rendering framework and discover the positive factors of Direct3D 11.2
- A sensible, example-driven, technical cookbook with a variety of illustrations and instance pictures to assist exhibit the innovations described
Who This publication Is For
Direct3D Rendering Cookbook is for C# .NET builders who are looking to examine the complex rendering concepts made attainable with DirectX 11.2. it truly is anticipated that the reader has at the least a cursory wisdom of snap shots programming, and even supposing a few wisdom of Direct3D 10+ is useful, it's not helpful. An knowing of vector and matrix algebra is required.
What you'll Learn
- Set up a Direct3D program and practice real-time 3D rendering with C# and SharpDX
- Learn ideas for debugging your Direct3D application
- Render a 3D setting with lighting fixtures, shapes, and materials
- Explore personality animation utilizing bones and vertex skinning
- Create extra floor element utilizing tessellation with displacement mapping and displacement decals
- Implement photograph post-processing projects inside compute shaders
- Use real-time deferred rendering strategies to enforce more desirable shading for lights and shadows
- Learn to software the photos pipeline with shaders utilizing HLSL applied by way of Shader version 5
The most up-to-date 3D pictures playing cards convey us striking visuals within the most recent video games, from Indie to AAA titles. this can be made attainable on Microsoft® structures together with workstation, Xbox consoles, and cellular units because of Direct3D– an element of the DirectX API devoted to exposing 3D photographs to programmers. Microsoft DirectX is the pics know-how powering all of modern day most well-liked video games. the most recent model— DirectX 11—features tessellation for film-like geometric aspect, compute shaders for customized images results, and stronger multithreading for larger usage. With it comes a few primary video game altering advancements to the best way we render 3D graphics.
Direct3D Rendering Cookbook presents specific .NET examples overlaying quite a lot of complicated 3D rendering recommendations to be had in Direct3D 11.2. With this publication, you'll tips on how to use the recent visible Studio 2012 snap shots content material pipeline, the best way to practice personality animation, the right way to use complex tessellation innovations, easy methods to enforce displacement mapping, practice photograph post-processing, and the way to take advantage of compute shaders for general-purpose computing on GPUs.
After masking a couple of introductory subject matters approximately Direct3D 11.2 and dealing with the API utilizing C# and SharpDX, we fast ramp as much as the implementation of a number complex rendering options, development upon the tasks we create and the talents we study in every one next bankruptcy. issues coated comprise utilizing the hot visible Studio 2012 images content material pipeline and photographs debugger, texture sampling, basic mapping, lights and fabrics, loading meshes, personality animation (vertex skinning), tessellation, displacement mapping, utilizing compute shaders for post-process results, deferred rendering, and eventually bringing all of this to home windows shop Apps for laptop and cellular. After finishing the recipes inside Direct3D Rendering Cookbook, you might have an in-depth knowing of a number complicated Direct3D rendering topics.

Additional resources for Direct3D Rendering Cookbook
Moving info from the GPU to CPU is sluggish and mapping the subresource can stall until eventually the GPU is prepared. C# can incur extra overhead if now not cautious, leading to an additional reminiscence replica operation. If the source is properly protected against additional use, the particular studying of the knowledge as soon as mapped might almost certainly take place inside of one other thread, yet care has to be taken, and the unmapping of the source needs to be performed in a thread-safe demeanour for the equipment context. there is extra… it'd be tempting to aim to take advantage of the group-shared reminiscence for the histogram calculation; in spite of the fact that, our threads probably have to write to any handle and a thread is just allowed to write down to its personal area of the crowd reminiscence with no synchronization. Any thread synchronization could probably defeat any capability functionality profits. analyzing from a similar situation in shared reminiscence throughout a number of threads is permitted. bankruptcy eight. Incorporating Physics and Simulations during this bankruptcy, we are going to disguise the next subject matters: utilizing a physics engine Simulating ocean waves Rendering debris advent during this bankruptcy, we are going to examine imposing physics and simulations into our scene rendering. we are going to first examine a CPU-based physics engine, after which we'll discover the ability of the GPU to simulate waves and render thousands of debris. utilizing a physics engine during this recipe, we'll expand our latest mesh renderer to help the simulation of physics inside a scene. we are going to proceed to exploit the integrated visible Studio pictures content material pipeline, and depend upon an easy mesh naming conference to designate static and dynamic gadgets inside our scene. preparing For our physics engine, we'll use BulletSharp, a . internet wrapper of the preferred Bullet Physics library utilized in many AAA online game and film titles. give some thought to the subsequent steps: obtain the BulletSharp library from https://code. google. com/p/bulletsharp/. it's also incorporated within the \External folder in the downloadable content material for this booklet. upload a connection with the \External\bulletsharp-2. 82\Release SharpDX\BulletSharp. dll meeting. observe Referencing the SharpDX model of the BulletSharp meeting makes use of the present SharpDX vector and matrix constructions. We use an instance scene to illustrate the physics engine. this can be to be had in the downloadable content material. A debug renderer classification, PhysicsDebugDraw, is integrated within the accomplished undertaking for debugging the inflexible physique shapes and constraints. this relies on . \Shaders\PhysicsDebug. hlsl and the BufferedDebugDraw category. ultimately, we'll desire a undertaking that has the MeshRenderer type to be had. the right way to do it… we'll start by way of loading our 3D scene and generate their corresponding inflexible our bodies within the Bullet Physics Library. upload the PhysicsScene1. fbx 3D scene to the venture and set construct motion to MeshContentTask. firstly of D3DApp. Run the place we initialize our renderers, load PhysicsScene1. cmo (the compiled mesh item dossier) and create the MeshRenderer circumstances, as follows:// Create and initialize the mesh renderer var loadedMesh = universal.
