Autodesk Maya is the defacto standard when it comes to modeling objects for games and high quality movies. Below mentioned are few of those tools, tips and techniques that can be of great help for those in the niche of 3D modeling.
Geometry and texture
One of the features tools of Maya is the Texture to Geometry tool which allows modelers to create a base mesh. You can start off by creating a plane with the same aspect ratio as the image that is projected. Once a texture is assigned to a plane, plane geometry can be selected and modified by using Modify, Convert and Texture to Geometry. An input image can then be selected and applied.
Quads for design
Considered as one of the basic 3d modeling tips for beginners, the use of quads for subdivision offers seamless interaction with the object. You can use triangles but stay away from N-gons. Predictable nature and easier access to enveloping while skinning makes quads a preferable choice among modelers.
Backface Culling has to be turned on in your Shading options if you want to import a million geometric shapes at the same time. A cluttered viewport will try to bring all of them in at the same time making it lag back for a moment.
Realistic and animated characters require proper movement of facial bones and muscles. It is therefore necessary for modelers to have thorough understanding of how movement takes place in facial muscles. It is imperative to have an idea of the character and its internal movement.
Minimum number of polygons which provide maximum detail ensures that complicated models are easier to design and interact with. Boolean tools can also help in creating complex looking models in an easy and creative manner.
One of the most appreciated 3d modeling tips and tricks in Maya is to get a repetitive shape to use the Animation Snapshot command. It is available under the “Animate”menu. A piece of geometry which is travelling along a motion path will create a duplicate copy of model every frame. Chain modeling like street lights and city street networks are good areas where this can be applied.
If you are considering a mesh retopologization, then look no further than Create Polygon Tool. It helps to draw a shaded part over the top of the high resolution image to create a lower resolution one. It is one of the featured Autodesk Maya modeling tips.
For creating realistic 3D models, you need to be proficient in using 3D CAD Software and understanding about modeling techniques. Let us see some of the commonly used 3D modeling techniques.
Commonly Used 3D Modeling Techniques
3D modeling techniques usually connect point sets with different surfaces, curved or linear, and utilize geometry related data for creation of wireframe models. In order to develop 3D models which have distinctive character of their own, you need to be creative and imaginative. This is similar to creating spectacular animation by leveraging your skills. 3D modeling is a teamwork wherein each creative artist would take care of a unique aspect of the character design.
From the perspective of 3D experts, creation of assets can be done using following popular techniques.
Subdivision or Box Modeling
- The technique is polygonal modeling based
- Work is started with a geometric primitive
- The shape is refined till the desired look is achieved
- Box modelers prefer to work in stages to remain organized
- Low resolution polygon meshes become the starting point
- Hard edges are made smoother through mesh subdivision after refining shapes
- Details are added as deemed suitable
- Sub-division of surfaces and shape refinement are repeatedly carried out
- This is done till sufficient polygonal details are suffused in the mesh
- The shape would now evolve which would materialize your concept accurately
- This is most commonly used polygonal modeling type
- The technique is used widely along with edge modeling methods
Contour or Edge Modeling
- Here, the artist does not start with a primitive shape
- The creation of the model occurs in pieces
- Loops of polygonal faces are placed with major contours
- Gaps between contours are filled
- Edge flow and topology needs to be managed meticulously for proper face modeling
- High precision can be obtained with contour modeling
- Model building process becomes easier if it is started with the outline of the shape
- Remaining part is modeled after drawing the outline
- Creating the shape from a properly defined solid polygonal mesh is not desirable initially
- Ideal for building character’s lips, nose, eyes and jawline
- Remaining parts spontaneously gets managed
Spline or NURBS Modeling
- The technique is particularly used in modeling objects for industrial and automobile units
- The model is constituted of surfaces which are smoothly interpreted
- A mesh is heaved amidst two or more Bezier curves
- The tool used for creating NURBS curves is functionally similar to Pen Tool
- The Pen tool is used in Adobe Illustrator or MS Paint or similar program
- Drawing of the curve takes place in 3D scape
- Editing of the curve is done through a series of handles called Control vertices
- For perfect modeling of NURBS space, curves are placed along major contours
- The 3D software then spontaneously gets the inlying space interpolated
- The modeling method is very fast
- Objects like wine glasses, plates, vases and other objects can be modeled
- Any object can be created with the help of algorithms
- No need of generating shapes manually by the 3D artists
- Creation of scenes and objects takes place with the help of user definable rules
- Parameters can be set for procedurally modeling organic objects like trees and leaves
- Objects that are highly complex in nature can be created in this manner
- The long time needed to manually create the models is waived off
- Organic creation of meshes take place in digital sculpting
- Wacom tablet device is used for molding and shaping the model
- The digital model resembles the real shape created by the sculptor with hand
- Real clay modeled with rake brushes yield shapes which are digitally emulated
- Creature and character modeling can be impeccably done with digital sculpting
- The process of creation is fast, efficient and conducive to higher productive
- Artists can work with meshes of high resolution
- Meshes can carry millions of polygons
- Unparalleled level of detailing in surfaces can be obtained with sculpted meshes
- The aesthetic appeal of the shape is more and the model is spontaneous
3D modeling offers numerous advantages but the one that really counts is the dramatic improvement in props, graphics and atmospherics. This bestows the shapes with realistic look. Designers around the world are having more enjoyable experience due to enhanced atmospherics offered by state of the art modeling techniques. Various immersive experience which is brought about by the creativity of graphic artists.
It is better if you can follow these tips to save your valuable time and effort. A wide plethora of professional company are available to help in your various requirements of 3d services which include modeling , rendering, and animation. But the thing you should always remember is that only a few are capable of sticking to highest standards and apex creativity. So, carry out an extensive market study and inquire properly before closing a deal.
