The resulting model (d) is smooth and well-shaped, but because all of the 3D parts are rooted in the drawing plane, they may intersect each other, resulting in a somewhat odd-looking “elephant”. It then inflates the model into 3D by solving a modified form of Poisson’s equation to produce a surface with a rounded cross-section (c). The system cuts the body’s front surface along that segment, and then stitches the front of the leg together with the body (b). First, the system identifies where the leg must be connected to the body (a) by finding the segment (red) that completes the open curve. To understand how a 3D model is created from these 2D regions, let’s look more closely at one part of the elephant. Steps in creating a 2D sketch of an elephant. The result is an ordered list of 2D regions. The user can also specify that some new parts should go behind the existing ones by drawing them with the right mouse button (c), and mark other parts as symmetrical by double-clicking on them (d). Drawing those additional strokes as open curves provides a hint to the system that they are meant to be smoothly connected with the regions they overlap. Then the user adds strokes to depict other body parts such as legs (b). The first step is to draw the body as a closed stroke (a). The result is a simple and intuitive user interface for sketching 3D figures.įor example, suppose the user wants to create a 3D model of an elephant. This abstraction makes the complex task of 3D modeling much easier: the user creates 2D regions by drawing their outlines, then the algorithm creates a 3D model by stitching the regions together and inflating them. The insight that makes this casual sketching approach possible is that many 3D models, particularly those of organic forms, can be described by an ordered set of overlapping 2D regions. There is also an online demo, where you can try it out for yourself.Ĭreating a walk cycle using Monster Mash.
#Anime girl 3d model base image software
With Monster Mash, the user sketches out a character, and the software automatically converts it to a soft, deformable 3D model that the user can immediately animate by grabbing parts of it and moving them around in real time. In this post, we describe Monster Mash, an open source tool presented at SIGGRAPH Asia 2020 that allows experts and amateurs alike to create rich, expressive, deformable 3D models from scratch - and to animate them - all in a casual mode, without ever having to leave the 2D plane. This turns out to be essential to the creative process - when each sketch is nearly effortless, it is possible to iteratively explore the space of possibilities far more effectively. What these casual modes have in common is that they allow an artist to express a complete thought quickly and intuitively without fear of making a mistake. To explore this concept, we start with the observation that most forms of artistic expression have a casual mode: a classical guitarist might jam without any written music, a trained actor could ad-lib a line or two while rehearsing, and an oil painter can jot down a quick gesture drawing. With the recent development of tools that facilitate game character creation and game balance, a natural question arises: is it possible to democratize the 3D animation process so it’s accessible to everyone? Because of its complexity, 3D animation is generally practiced by teams of skilled specialists and is inaccessible to almost everyone else, despite decades of advances in technology and tools.
Posted by Cassidy Curtis, Visual Designer and David Salesin, Principal Scientist, Google ResearchģD computer animation is a time-consuming and highly technical medium - to complete even a single animated scene requires numerous steps, like modeling, rigging and animating, each of which is itself a sub-discipline that can take years to master.
