In 2018, with the release of NVIDIA’s RTX series GPUs, real-time ray tracing finally became accessible to game developers, content creators, and consumers. It is a technology that will forever change graphics processing.

To help developers navigate this new technology, a wide-ranging book on the topic is being published early this year: Ray Tracing Gems.

We have some great news: Readers of NVIDIA’s Dev News Center get early access to the text, at no cost!  NVIDIA will be distributing the book for free in its entirety, as a series of seven PDFs. Every few days, a new section of the book will be made available.

The book Ray Tracing Gems is nearing completion, with the hardback version to be available mid-March at GDC and GTC. Our main goal with this book is educating developers at all levels about important concepts and the state of the art in ray tracing, with an emphasis on real-time rendering. You can see the full Table of Contents on this site, or order the hardcover version from Apress or on Amazon.

We wanted to make the contents available as soon as the chapters reach a finished state. The book is “Open Access,” under the terms of the Creative Commons Attribution 4.0 International License (CC-BY-NC-ND), “which permits use, duplication, distribution, and reproduction in any medium or format, as long as appropriate credit is given to the original author(s) and the source, a link is provided to the Creative Commons license, and any changes made are indicated.”

As such, we will be releasing a part of the book every few days, as we process them. These chapter are “preprints,” in that they will look a bit different than the publisher’s layout, but the information is the same, barring any last-minute fixes. By the end of February, the professionally laid-out electronic version of the final book from Apress will be available for free (formats to be determined), along with the code repository.

Most folks who make games are aware of the various transformations that must take place to render convert a 3d model from object or artist space to screen or pixel space.  I think most folks also kind of understand what a projection matrix is.  However, I find that many have trouble explaining what each number in a projection matrix actually means.  The goal of this article is to take away the magic of those numbers and provide clarity with regards to what each number means in a projection matrix.

Open Image Denoise Overview

Intel® Open Image Denoise is a collection of high-performance, high-quality denoising filters for images rendered with ray tracing. Open Image Denoise is part of the Intel Rendering Framework and is released under the permissive Apache 2.0 license.

The purpose of Open Image Denoise is to provide an open, high-quality, efficient, and easy-to-use denoising library that allows one to significantly reduce rendering times in ray tracing based rendering applications. It filters out the Monte Carlo noise inherent to stochastic ray tracing methods like path tracing, reducing the amount of necessary samples per pixel by even multiple orders of magnitude (depending on the desired closeness to the ground truth).

Open Image Denoise supports Intel® 64 architecture based CPUs and compatible architectures, and runs on anything from laptops, to workstations, to compute nodes in HPC systems. It is efficient enough to be suitable not only for offline rendering, but, depending on the hardware used, also for interactive ray tracing.

Open Image Denoise internally builds on top of Intel Math Kernel Library for Deep Neural Networks (MKL-DNN), and fully exploits modern instruction sets like Intel SSE4, AVX2, and AVX-512 to achieve high denoising performance. A CPU with support for at least SSE4.2 is required to run Open Image Denoise.

This article shows a trivial implementation of a ray marching, the goal is to go a little bit beyond simple spheres I rendered in my raytracer project. I do not aim at getting photorealistic images, I want to have a simple stuff applicable to video games.

As always, we only have a bare compiler at our disposal, no third-party libraries are allowed. I don't want to bother with window managers, mouse/keyboard processing and so on. The result of our program will be a simple picture saved on the disk. I do not pursue speed/optimization at all, my goal is to show the underlying principles.

New SDK Release for Vulkan 1.1.97.0

LunarG releases new SDKs that include the most recent extensions plus the new Vulkan GPU-Assisted Validation feature and the Vulkan Configurator application.

Much of the documentation for this SDK is contained in the Getting Started Guide, found in the Documentation directory of the SDK and on the LunarXchange website.
Overview of new features in Vulkan SDK 1.1.97.0

- The Vulkan validation layers have added “GPU-Assisted Validation,” which checks for out-of-bounds access to image/texel descriptor arrays at shader execution time (aka “Bind-less” validation). This feature is disabled by default. See the SDK “Validation Layers” documentation for details about this feature and how to enable it.

- SDK 1.1.92 introduced the Vulkan Configurator, a graphical application that allows a user to specify which layers will be loaded by Vulkan applications at runtime. SDK 1.1.97 combines vulkaninfo, vkvia, and the existing layer management functionality of vkconfig into one convenient tool. Note this new functionality may not be available on every platform. Additional information about the enhanced Vulkan Configurator can be found here.

- The SDK now includes a chunked version of the Vulkan specification and can be found here.

- Since the release of SDK 1.1.92.0, the following extensions have been added to the Vulkan spec and may be supported by a Vulkan device. To query extensions available to a given physical device, call vkEnumerateDeviceExtensionProperties()or contact the hardware vendor.

VK_EXT_buffer_device_address
VK_EXT_fragment_density_map
VK_EXT_memory_budget
VK_EXT_memory_priority
VK_EXT_scalar_block_layout
VK_EXT_separate_stencil_usage
VK_EXT_validation_features
VK_KHR_depth_stencil_resolve
VK_KHR_shader_float_controls
VK_KHR_shader_float16_int8
VK_KHR_swapchain_mutable_format

- Improved validation coverage and bug fixes

3D-Tech News Around The Web / Raymarching distance fields tutorial
« on: January 21, 2019, 04:40:28 PM »
Quote
Rendering an image involves determining the colour of every pixel in the image, which requires figuring out what surface lies behind the pixel in the world, and then 'shading' it to compute a final colour.

Current generation GPUs take triangle meshes as input, rasterise them into pixels (called fragments before they're drawn to a display), and then shade them to calculate their contribution to the image. While this pipeline is currently ubiquitous, it is also complicated and not necessarily the best way to learn graphics.

An alternative approach is to cast a ray through each pixel and intersect it with the surfaces in the scene, and then compute the shading.

This course introduces one technique for raycasting through 'distance fields'. A distance field is a function that returns how close a given point is to the closest surface in the scene. This distance defines the radius of a sphere of empty space around each point. Signed distance fields (SDFs) are distance fields that are defined both inside and outside objects; if the queried position is 'inside' a surface, its distance will be reported as negative, otherwise it will be positive.

Q2VKPT is the first playable game that is entirely raytraced and efficiently simulates fully dynamic lighting in real-time, with the same modern techniques as used in the movie industry. The recent release of GPUs with raytracing capabilities has opened up entirely new possibilities for the future of game graphics, yet making good use of raytracing is non-trivial. While some games have started to explore improvements in shadow and reflection rendering, Q2VKPT is the first project to implement an efficient unified solution for all types of light transport: direct, scattered, and reflected light. This kind of unification has led to a dramatic increase in both flexibility and productivity in the movie industry. The chance to have the same development in games promises a similar increase in visual fidelity and realism for game graphics in the coming years.

This project is meant to serve as a proof-of-concept for computer graphics research and the game industry alike, and to give enthusiasts a glimpse into the potential future of game graphics. Besides the use of hardware-accelerated raytracing, Q2VKPT mainly gains its efficiency from an adaptive image filtering technique that intelligently tracks changes in the scene illumination to re-use as much information as possible from previous computations.

Much has been written lately about C++, the direction the language is taking and how most of what gets called “modern C++” is just a no-go zone for game developers.

Although I fully agree with the sentiment, I tend to look at C++ evolution as the effect of a pervasive set of ideas that dominate the minds of most developers. In this post I’ll try to put some of my thoughts on these ideas in order and, hopefully, something coherent will come up.

« on: January 18, 2019, 02:02:10 PM »

A library that I work on often these days, meshoptimizer, has changed over time to use fewer and fewer C++ library features, up until the current state where the code closely resembles C even though it uses some C++ features. There have been many reasons behind the changes - dropping C++11 requirement allowed me to make sure anybody can compile the library on any platform, removing std::vector substantially improved performance of unoptimized builds, removing algorithm includes sped up compilation. However, I’ve never quite taken the leap all the way to C with this codebase. Today we’ll explore the gamut of possible C++ implementations for one specific algorithm, mesh simplifier, henceforth known as simplifier.cpp, and see if going all the way to C is worthwhile.
