![]() ![]() A value greater than 0 indicates a point inside the object with the field value indicating the distance from the surface. The object surface is those places where the distance is 0, that is the 'zero crossing' of the field. Underestimation won't impair the ability to converge to the correct solution but the convergence will be slower.Ī distance field function takes a space or plane coordinates and calculates an estimate of the distance from that point to the object surface. If the distance estimate deviates too much from the true distance the ray will miss the object (overshoot) if it overestimates that distance. The distance field does not have to be mathematically exact to allow proper convergence, but the more exact the distance estimate is, the faster the convergence will be. This is because the DF field itself gives some information about the distance to the surface which allows the sampling to be much more efficient by converging quickly to the surface.Ī distance field is just a scalar field where the value of the field gives a good (or exact) approximation of the distance to the surface. Ray Marching is needed when the mathematics that describe the object are too complex to find intersections analytically, typically when the object is an entire procedural planet like in Voyager case.īy using distance fields Voyager can find the intersection of the ray with the surface of 3D object much more quickly than using the brute force technic of ray marching. It is a slow process as the object or terrain have to be sampled many times to know where the ray intersects the object. Ray marching essentially calculates the intersection of the possible light rays between the observer and the scene by sampling along the ray. The technical information may help you to understand the reasoning behind the guidelines and develop your own techniques.ĪrtMatic Voyager uses a technique called ray marching () to render images. This document covers the details you need to know to create or modify 3D objects represented by distance fields (DF for short) and gives many practical guidelines. The ArtMatic Pro/Voyager combination provides all the tools & primitives needed to create a never-ending variety of landscapes and worlds.ArtMatic Voyager Documentation : Building Objects - DFRM Guide Building 3D Objects : DFRM GuideĪrtMatic Voyager uses a unique approach to 3D objects modeling & rendering called Distance Field Ray Marching, DFRM for short. #Artmatic voyager pro#For those who want to build their own worlds and textures from scratch, ArtMatic Pro can be used to design new planets OR to add elements to the built-in planets. Any built-in planet can be combined with up to 6 ArtMatic surfaces at once. ![]() ![]() ![]() These elements can be used on their own or in limitless combinations. You can use any of the over 400 ArtMatic elements (planet surfaces, color textures, artifacts, cities, cloud systems, backdrops and atmospheres) provided with ArtMatic Voyager to expand on the possibilities of the built-in planets. ArtMatic Voyager comes with a large collection of professional-quality starter systems. Illustrators, filmmakers and graphic designers in need of landscape backgrounds and realistic or fantastic scenery will love ArtMatic Voyager.īesides its practical uses, ArtMatic Voyager is also able to offer sheer pleasure as you explore and travel virtual worlds bigger than our own Earth. Using new non-polygonal techniques for rendering, ArtMatic Voyager is both powerful and easy to use. ArtMatic Voyager invites you to create, explore and discover entire planets much larger than our own. Version: 1.6.2ĪrtMatic Voyager creates 3D landscapes with exquisite realism and detail. Offers support for cutting-edge 3D landscape creation. ![]()
