                Richard A. Hawley

                Richard Hawley started programming in the early 1980s at the start of the home computer craze with the Sinclair ZX-81. Before leaving high school he had worked on three game projects for Assassin Software and later worked on conversions of classic strategy board games for 8- to 16-bit machines. He went on to develop end-user tools for popular flight simulations including Empire Interactive’s Enemy Engaged helicopter series and the highly successful Origin Jane’s Longbow series (MissioneerPlus). He’s the director of Tricubic Studios, a small UK company dedicated to creating simulation and training environments using off-the-shelf 3D engines including Unity and Leadwerks. Together with technical artist David Hopkinson (Total War: English Civil War conversion) and physics guru Fred Naar (creator of Helicopter Total Realism for Microsoft Flight Simulator X) they are collectively known for their work on helicopter simulations.

                In Detail

                Grome is an environmental modeling package that makes the creation and editing of large terrain areas an easy task. Grome has the ability to take huge datasets suitable for MMOs and simulations and this marks it as a welcome tool in a developer’s toolbox.

                "Grome Terrain Modeling with Ogre3D, UDK, and Unity3D" shows you how to get to grips with this powerful terrain construction tool. This book walks you through how to create, edit, and export terrains to Unity3D, UDK, and Ogre3D.

                "Grome Terrain Modeling with Ogre3D, UDK, and Unity3D" will guide you in creating new Grome terrain projects, splitting terrain into multiple zones, adding textures and ground features, and exporting your creations into a game engine.

                You will be guided through the Grome toolset to create potentially massive procedurally generated fractal landscapes, adding multiple texture layers for different seasonal effects, and adding materials for performance enhancing lighting effects.

                You will learn how to export your landscapes to the most common 3D engines; Unity3D (PC and mobile), UDK, and Ogre3D. It’s a powerful addition to any production pipeline if your game needs terrain.

                Approach

                This book is a practical guide with examples and clear steps to explain terrain modeling with Grome.

                Who this book is for

                If you’re a developer or artist looking for a guide to walk you through GROME 3.1, then this book is for you. This book will help you from the first step to exporting a terrain as a workable art asset in a game engine.
