3D Modeling and Computer Graphics in Virtual Reality

Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program. The resulting image is referred to as the render. Multiple models can be defined in a scene file containing objects in a strictly defined language or data structure. The scene file contains geometry, viewpoint, texture , lighting , and shading information describing the virtual scene. The data contained in the scene file is then passed to a rendering program to be processed and output to a digital image or raster graphics image file. The term "rendering" is analogous to the concept of an artist's impression of a scene.

Construction and presentation of a virtual environment using panoramic stereo images of a real scene and computer graphics models Abstract: The progress in computer graphics has made it possible to construct various virtual environments such as urban or natural scenes. The paper proposes a hybrid method to construct a realistic virtual environment containing an existing real scene.

Physically based sound is an important emerging approach to computer synthesis of realistic synchronized sounds for physically based animation and real-time virtual environments. A major challenge for learning and implementing these sound techniques is the wide range of physically based models and sound phenomena involved, as well as the need for optimizations. Many publications on physically based animation and sound rendering assume mathematical background that many in the graphics community lack. The result is that learning physics-based sound techniques is unnecessarily difficult for many interested students and practitioners. The main goal of this course is to make the principles and methods of physically based sound accessible to a broader computer-graphics audience. The course covers sound-source models for sonifying important phenomena from physics-based animation: rigid bodies, brittle fracture, thin-shells, cloth, deformable collisions and contact, fluids, and fire.

VRfx – A User Friendly Tool for the Creation of Photorealistic Virtual Environments

In the era of digital information technologies, 3D modeling and computer graphics techniques not only apply to the development of virtual models for computer simulation, artificial intelligence AI , big data analytics, etc. However, the computer graphics effect and visual realism are usually the trade-offs with the real-time and realistic interaction in VR. In this book chapter, we would like to review the general flow of the VR program development process, and the recent 3D modeling and texture painting techniques used in VR. On the other hand, we would introduce some of the key 3D modeling and computer graphics techniques that can be applied in VR in order to enhance the speed of interaction. The key techniques including smoothing techniques and mesh editing modifiers are not only useful for the designers to learn the 3D modeling process, but it also helps to create less complex mesh models maintaining good visual effects. The techniques are particularly important in the development of 3D models to satisfy the demanding computation requirement of real-time interaction in VR program. In the past few decades, virtual reality VR has been widely used in many different areas including entertainment, education and training, manufacturing, medical and rehabilitation.

This volume presents novel computational models for representing digital humans and their interactions with other virtual characters and meaningful environments. In this context, we describe efficient algorithms to animate, control, and author human-like agents having their own set of unique capabilities, personalities, and desires. We begin with the lowest level of footstep determination to steer agents in collision-free paths. Steering choices are controlled by navigation in complex environments, including multi-domain planning with dynamically changing situations.

 Все еще не взломан. Через пятнадцать с лишним часов. Стратмор подался вперед и повернул к Сьюзан монитор компьютера.

Чуть ли не до двадцати лет она была худой и нескладной и носила скобки на зубах, так что тетя Клара однажды сказала, что Господь Бог наградил ее умом в утешение за невзрачные внешние данные.

 Не знаю. Все зависит от того, что ударило в голову автору.  - Он привлек внимание к тексту на экране.  - Кто-нибудь может мне объяснить, что это .

Кольцо, - совсем близко прозвучал голос. Беккер поднял глаза и увидел наведенный на него ствол. Барабан повернулся. Он снова с силой пнул ногой педаль стартера.

Ей обрыдли ее испанская семейка и местное житье-бытье.
