The polygon-mesh approach to 3D modeling was a huge advance, but today its limitations are clear. Longer render times for increasingly complex images effectively cap image complexity, or else stretch ...budgets and schedules to the breaking point. Comprised of contributions from leaders in the development and application of this technology, Point-Based Graphics examines it from all angles, beginning with the way in which the latest photographic and scanning devices have enabled modeling based on true geometry, rather than appearance. From there, it's on to the methods themselves. Even though point-based graphics is in its infancy, practitioners have already established many effective, economical techniques for achieving all the major effects associated with traditional 3D Modeling and rendering. You'll learn to apply these techniques, and you'll also learn how to create your own. The final chapter demonstrates how to do this using Pointshop3D, an open-source tool for developing new point-based algorithms. * The first book on a major development in computer graphics by the pioneers in the field * Shows how 3D images can be manipulated as easily as 2D images are with Photoshop

Programski jezik Logo jedan je od prvih programskih jezika za poučavanje djece nastao još 1966., a primarno je služio za učenje geometrije. Logo se temelji na ideji kornjačine grafike, koja je i ...danas još uvijek itekako prisutna u razvijanju računalnog razmišljanja i za početno učenje programiranja. Jasno je da je u vrijeme nastajanja Loga ideja osobnog računala bila tek ideja iz znanstvene fantastike, pa i samog računarstva kao samostalne znanstvene discipline. Unatoč tome, vizionarski pogled Seymoura Paperta postavio je temelje računalnog razmišljanja i poučavanja programiranja od najranije dobi koji su danas sveprisutni. Kako je Papert bio primarno matematičar, s predmetom zanimanja za poučavanje matematike, tako je Logo zapravo nastao u svrhu poučavanje geometrije i olakšavanja djeci savladavanja osnovnih pojmova iz područja geometrije kao što su mnogokuti. Ipak, nema puno istraživanja koja se bave istraživanjem utjecaja Loga na razumijevanje osnovnih pojmova geometrije. Cilj ovog rada je istražiti utjecaj korištenja programskog jezika Logo u poučavanju geometrije koja se obrađuje u osmim razredima osnovne škole, s naglaskom na osnovne pojmove o mnogokutima, identificirati učestale pogreške pri učenju mnogokuta te ocijeniti učinkovitost Logo programa u poticanju interaktivnog učenja geometrije. U ovom istraživanju koristile su se kvalitativne i kvantitativne metode kako bi se pružio sveobuhvatan uvid u ovu temu. Istraživanje je pokazalo da primjena kornjačine grafike u programskom jeziku Logo u poučavanju osnovnih pojmova o mnogokutima rezultira boljim razumijevanjem pojmova mnogokuta kod učenika te potiče interaktivno učenje geometrije.
The Logo programming language is one of the first programming languages designed for children, originating in 1966 primarily for teaching geometry. The logo is based on the concept of turtle graphics, which remains prevalent today in developing computational thinking and for initial programming education. It is clear that at the time of Logo's inception, the idea of personal computers was still in the realm of science fiction, as was computer science as an independent discipline. However, Seymour Papert's visionary outlook laid the foundation for computational thinking and programming education from an early age, which is ubiquitous today. As Papert was primarily a mathematician with a focus on mathematics education, Logo was developed specifically for teaching geometry and facilitating children's understanding of basic geometric concepts such as polygons. Nevertheless, there is limited research on the impact of Logo on the understanding of basic geometric concepts. This study aims to investigate the influence of using the Logo programming language in teaching geometry to eighth graders, with a focus on fundamental polygon concepts, identify common errors in learning polygons, and assess the effectiveness of the Logo program in promoting interactive geometry learning. This research utilized both qualitative and quantitative methods to provide a comprehensive insight into this topic. The study showed that the implementation of turtle graphics in the Logo programming language for teaching basic polygon concepts results in a better understanding of polygon concepts among students and encourages interactive geometry learning.

Abstract
In this digital era, technology has changed rapidly advancements, including the usage of augmented reality, which has become increasingly popular. The fusion of virtual and real-world elements by augmented reality creates memorable and dynamic user interactions. The emergence of these tools has made it simpler to integrate augmented reality into web applications. By leveraging raw WebGL and GLSL shaders, we aim to investigate and establish web-based augmented reality environments via the Three.js library. WebGL serves as the authoritative standard for 3D graphical rendering within web-based interfaces, whereas GLSL functions as the scripting language responsible for regulating the visual presentation produced by WebGL. Three.js serves as a JavaScript toolset designed to create interactive, web-based 3D graphics. In this study, an exploration of raw WebGL and GLSL shaders is conducted to analyze the augmented reality web experience. The implemented shaders are combined with Three.js and AR.js tools to construct a captivating augmented reality atmosphere. Furthermore, a comparison is made between the results of using GLSL and WebGL in the context of augmented reality on the web. The analysis demonstrates that GLSL outperforms WebGL in web-based augmented reality scenarios. GLSL shaders provide better performance for displaying virtual objects in augmented reality.
