What is a Ray Tracing GPU?

Ray tracing is a popular rendering technique in 3D computer graphics. It is used to trace ray paths to enhance the precision and effects of light, shadow, and reflection. A few years ago, ray tracing was thought to be best for computer images and television VFX due to its high rendering time. However, due to GPU acceleration through hardware improvement, real-time ray tracing has become the new normal. This has significantly increased ray tracing application areas.

What is a Ray Tracing GPU?

A ray tracing GPU is the graphics card that has the hardware to support the rendering technique. Ray tracing brings realistic-looking shadows, lightning, caustics, reflections, and immersion into the virtual world. However, getting all this into games and other applications is a complicated task. Hence, only specific GPUs with high hardware capabilities can support it. These GPUs are what we call ray tracing GPUs.

The ray tracing GPUs introduce new workloads, such as denoising image and ray/triangle intersection, of the hardware. Ray tracing GPUs are capable of rendering various visual effects. Some of these optical effects include reflection, scattering, dispersion, and refraction.

You can use E2E Networks’ cloud servers to get the best out of the ray tracing GPUs. Our NVIDIA GPU cloud servers come at affordable rates to help you efficiently manage large volumes of data and complex programs. Using our NVIDIA GPU cloud servers allows you to seamlessly explore various ray tracing techniques, including reflections, shadows, illumination, and caustics.

What are the Different Ray Tracing Techniques?

You can use ray tracing in multiple ways ranging from reflections to shadows to illumination to caustics and ambient occlusion. Below-mentioned are some of the standard ray tracing techniques popularly used in the gaming domain and other fields.

  • Ray traced reflections

Ray tracing casts rays on various reflective surfaces, including water and glass. It then captures the reflections and projects it on the screen. To better understand it, we can take the example of Battlefield V, the first game that used real-time ray tracing. It specified surfaces, such as glass and water, that reflect light rays. Ray tracing then, casts rays on the reflective surfaces and projects the screen’s output for precise reflection effects.

  • Ray traced shadows

The ray tracing technique casts rays on characters and objects that can block light to provide realistic-looking shadows. There can be multiple light sources coming from different angles, which can make shadowing difficult. Ray tracing allows you to segregate light traces from various sources and curves, making it easier to manage each ray individually.

  • Ray traced illuminations

With their ray tracing capabilities, NVIDIA GPUs allow you to precisely model the effect of light and how it bounces from objects. This lets you quickly implement global illumination systems into games, engineering, and several other application areas.

  • Ray traced caustics

Caustic is a phenomenon of focusing and projecting the light rays reflected by curved or imperfect surfaces. While many attempts have been made, especially in the gaming domain, they were not accurate enough to create realistic caustics. Ray tracing allows you to render life-like caustics.

Which GPUs Support Ray Tracing?

The latest NVIDIA graphics cards from the RTX edition support real-time ray tracing. Some of the names to be familiar include the following:

  • Nvidia GeForce RTX 2060
  • Nvidia GeForce RTX 2060 Super
  • Nvidia GeForce RTX 2070
  • Nvidia GeForce RTX 2070 Super
  • Nvidia GeForce RTX 2080
  • Nvidia GeForce RTX 2080 Super
  • Nvidia GeForce RTX 2080 Ti
  • Nvidia Titan RTX

Applications of Ray Tracing GPUs

Ray tracing has been well-known for its applications in the media and entertainment field. It is used to capture shadows and reflections in a frame precisely for a more realistic look. However, ray tracing applications do not limit to media and entertainment, many other fields can leverage ray tracing too.

  • Developing games

Ray tracing has become the buzzword in the gaming world. Gaming developers thrive on making their games more realistic, and what better technique than ray tracing? With ray tracing, developers can introduce practical reflections and life-like shadows into games.

There are shadows and reflections in games without ray tracing support too. But the significant difference between the shadows and reflections is that they are static or not dynamic. The shadows and reflections without ray tracing are just a package of animations bunched together, which will always be the same. On the other hand, ray tracing enabled reflections are more dynamic and realistic. Some of the majorly popular games using ray tracing are:

  • Cyberpunk 2077
  • Call of Duty: Black Ops Cold War
  • Battlefield V
  • Fortnite
  • Minecraft: Bedrock Edition
  • Dirt 5
  • Watch Dogs: Legion
  • Spider-Man: Miles Morales

Similar to rays, ray tracing can also track sound waves. Hence, developers can also use it for more immersive sound and echo in video games. Although there is not much exploration done in this ray tracing application, hardware advancements will undoubtedly bring this into effect shortly.

  • Training AI models for image recognition

Training complex AI models for image recognition requires GPU acceleration. Not directly, but ray tracing can help accelerate the training procedure. NVIDIA has some great deep learning GPUs, majorly the ones that are recently launched. However, ray tracing can further accelerate it with the help of precise shadow and reflection capturing.

Deep learning models are trained with data and images in the case of image recognition. Due to the lack of precision in each image, developers have to use millions of pictures to train a single deep learning model. Ray tracing can help increase the accuracy, thereby reducing the time required to prepare the models. However, the developers may still have to train the models with numerous images; the results will be far better when trained with ray tracing frames.

Its sound waves tracing capabilities bring in the possibility of becoming a useful application in the voice recognition area. It can help denoise sound waves so that developers can train deep learning models faster.

  • Product design and virtual prototyping

Ray tracing is useful in all the stages of product designing and prototyping, right from the designing and evaluation to creating images for sales. Engineers and designers use them to create a clear and realistic looking design for proposing. The manufacturers then use it to build and test the product virtually using graphics.

When all the evaluation is complete and the product comes into the market, the sales and marketing team can also use ray tracing. The marketing team can create amazing images of the product for promotion. They can also use it to display the usage of the product realistically.

  • Designing architecture

Similar to product designers, architects can use ray tracing and its precision to design a blueprint of any structure. Unfortunately, hand-made designs cannot produce realistic illuminations. Several computer programs that can design model objects cannot model shadow and light precisely.

Computer-aided design (CAD) programs allow architects to introduce light by providing location, distribution, orientation, and color. But still, they do not come anywhere close to ray tracing. Backward ray tracing can precisely render architectural design by creating realistic images.

  • Engineering

Ray tracing is fully capable of rendering global illumination models. Global illumination is a term used to describe a system model that can consider all of the light, including the direct and indirect light (shadow and reflection) in an environment. The global illumination model helps engineers simulate light behavior in real life and build a model accordingly.

  • Animation

Ray tracing has paved the way for several new possibilities in the animation world. Traditionally, the process of creating animations was very complicated and required a lot of time. The introduction of ray tracing in animation has eliminated the need to work separately on the shadows and reflections, as it can all be done in a single frame now.

Animation artists can use ray tracing to add fancy shadowing effects for a more realistic feel. We can see some of the recent uses of ray tracing in popular animations like Beauty and the Beast, Aladdin, and Toy Story.

To put it simply, any industry that requires the use of computer-generated imagery or rendering can benefit from real-time ray tracing. The best way to leverage ray tracing is with NVIDIA servers on E2E Networks’ cloud. NVIDIA offers some of the best GPUs, and with our Windows cloud servers, the benefits of NVIDIA GPUs are further enhanced.

Image-based 3D Object Reconstruction State-of-the-Art and trends in the Deep Learning Era

3D reconstruction is one of the most complex issues of deep learning systems. There have been multiple types of research in this field, and almost everything has been tried on it — computer vision, computer graphics and machine learning, but to no avail. However, that has resulted in CNN or convolutional neural networks foraying into this field, which has yielded some success.

The Main Objective of the 3D Object Reconstruction

Developing this deep learning technology aims to infer the shape of 3D objects from 2D images. So, to conduct the experiment, you need the following:

  • Highly calibrated cameras that take a photograph of the image from various angles.
  • Large training datasets can predict the geometry of the object whose 3D image reconstruction needs to be done. These datasets can be collected from a database of images, or they can be collected and sampled from a video.

By using the apparatus and datasets, you will be able to proceed with the 3D reconstruction from 2D datasets.

State-of-the-art Technology Used by the Datasets for the Reconstruction of 3D Objects

The technology used for this purpose needs to stick to the following parameters:

  • Input

Training with the help of one or multiple RGB images, where the segmentation of the 3D ground truth needs to be done. It could be one image, multiple images or even a video stream.

The testing will also be done on the same parameters, which will also help to create a uniform, cluttered background, or both.

  • Output

The volumetric output will be done in both high and low resolution, and the surface output will be generated through parameterisation, template deformation and point cloud. Moreover, the direct and intermediate outputs will be calculated this way.

  • Network architecture used

The architecture used in training is 3D-VAE-GAN, which has an encoder and a decoder, with TL-Net and conditional GAN. At the same time, the testing architecture is 3D-VAE, which has an encoder and a decoder.

  • Training used

The degree of supervision used in 2D vs 3D supervision, weak supervision along with loss functions have to be included in this system. The training procedure is adversarial training with joint 2D and 3D embeddings. Also, the network architecture is extremely important for the speed and processing quality of the output images.

  • Practical applications and use cases

Volumetric representations and surface representations can do the reconstruction. Powerful computer systems need to be used for reconstruction.

Given below are some of the places where 3D Object Reconstruction Deep Learning Systems are used:

  • 3D reconstruction technology can be used in the Police Department for drawing the faces of criminals whose images have been procured from a crime site where their faces are not completely revealed.
  • It can be used for re-modelling ruins at ancient architectural sites. The rubble or the debris stubs of structures can be used to recreate the entire building structure and get an idea of how it looked in the past.
  • They can be used in plastic surgery where the organs, face, limbs or any other portion of the body has been damaged and needs to be rebuilt.
  • It can be used in airport security, where concealed shapes can be used for guessing whether a person is armed or is carrying explosives or not.
  • It can also help in completing DNA sequences.

So, if you are planning to implement this technology, then you can rent the required infrastructure from E2E Networks and avoid investing in it. And if you plan to learn more about such topics, then keep a tab on the blog section of the website

A Comprehensive Guide To Deep Q-Learning For Data Science Enthusiasts

For all data science enthusiasts who would love to dig deep, we have composed a write-up about Q-Learning specifically for you all. Deep Q-Learning and Reinforcement learning (RL) are extremely popular these days. These two data science methodologies use Python libraries like TensorFlow 2 and openAI’s Gym environment.

So, read on to know more.

What is Deep Q-Learning?

Deep Q-Learning utilizes the principles of Q-learning, but instead of using the Q-table, it uses the neural network. The algorithm of deep Q-Learning uses the states as input and the optimal Q-value of every action possible as the output. The agent gathers and stores all the previous experiences in the memory of the trained tuple in the following order:

State> Next state> Action> Reward

The neural network training stability increases using a random batch of previous data by using the experience replay. Experience replay also means the previous experiences stocking, and the target network uses it for training and calculation of the Q-network and the predicted Q-Value. This neural network uses openAI Gym, which is provided by taxi-v3 environments.

Now, any understanding of Deep Q-Learning   is incomplete without talking about Reinforcement Learning.

What is Reinforcement Learning?

Reinforcement is a subsection of ML. This part of ML is related to the action in which an environmental agent participates in a reward-based system and uses Reinforcement Learning to maximize the rewards. Reinforcement Learning is a different technique from unsupervised learning or supervised learning because it does not require a supervised input/output pair. The number of corrections is also less, so it is a highly efficient technique.

Now, the understanding of reinforcement learning is incomplete without knowing about Markov Decision Process (MDP). MDP is involved with each state that has been presented in the results of the environment, derived from the state previously there. The information which composes both states is gathered and transferred to the decision process. The task of the chosen agent is to maximize the awards. The MDP optimizes the actions and helps construct the optimal policy.

For developing the MDP, you need to follow the Q-Learning Algorithm, which is an extremely important part of data science and machine learning.

What is Q-Learning Algorithm?

The process of Q-Learning is important for understanding the data from scratch. It involves defining the parameters, choosing the actions from the current state and also choosing the actions from the previous state and then developing a Q-table for maximizing the results or output rewards.

The 4 steps that are involved in Q-Learning:

  1. Initializing parameters – The RL (reinforcement learning) model learns the set of actions that the agent requires in the state, environment and time.
  2. Identifying current state – The model stores the prior records for optimal action definition for maximizing the results. For acting in the present state, the state needs to be identified and perform an action combination for it.
  3. Choosing the optimal action set and gaining the relevant experience – A Q-table is generated from the data with a set of specific states and actions, and the weight of this data is calculated for updating the Q-Table to the following step.
  4. Updating Q-table rewards and next state determination – After the relevant experience is gained and agents start getting environmental records. The reward amplitude helps to present the subsequent step.  

In case the Q-table size is huge, then the generation of the model is a time-consuming process. This situation requires Deep Q-learning.

Hopefully, this write-up has provided an outline of Deep Q-Learning and its related concepts. If you wish to learn more about such topics, then keep a tab on the blog section of the E2E Networks website.
