Marketing Ideas For Artists, Part Two - 8 Tips on How to Use the Internet to Get Your Art Noticed Start a blog. This must be one of the top ways advocated for artists or any business for that matter to reappear in peoples inboxes without actually "selling" them something. |
3D Applications and Virtual Camera Top, front, left, right, back, bottom, and isometric (a kind of angled bird's eye view) are all different angles from which a model can be viewed. Since there are lines converging, objects appear the same size whether they are close or far away. The advantages of this sort of viewpoint include the ease in which you can align objects. However, one orthographic view by itself is fairly useless because you cannot tell depth. |
An important idea behind perspective is that every shape and object depicted on the projection plane sends a "ray" to the viewpoint, or our eye. Computer 3D applications rely heavily on this concept through a process called ray tracing. Imagine that all objects in a scene emit these theoretical "rays." On their way to the viewpoint, they will pass through the projection plane that, in the case of computers, is the screen. |
Understanding the Digital 3D World Art Understanding the Digital 3D World Art has been and continues to be an evolutionary process. Although it has probably been around for as long as humankind, the goals and methods have changed dramatically from the French cave paintings of Lascaux to the Egyptian Geese of Medum to Hokusai's The Great Wave to Boticelli's The Birth of Venus to Ingres' Grande Odalisque to Rothko's Four Darks in Red to the work of John Lasseter and his crew in Toy Story, Toy Story 2, and A Bug's Life. |
Now that we have looked at all the times to return to another step, it needs to be said that there is also a time to stop. The last step of the process is to know when to stop and let the project stand. There is always something that could be done a little better, but there are other stories to tell, more motion to study, and ideas to explore. |
3D Animations Work Best When There is a Clear Concept It is during the editing process that you can begin to see if all the elements we just discussed have come together. If not, back up, rework, and try again. Often, during the editing process, sound is added as an afterthought. However, sound is so important that it really deserves its own mention and category step. |
Lower Polygon Counts Keep Computers Running Quickly Every 3D application has a collection of shapes very well known named 'primitives'. These stock shapes, whether polygon or NURBS based, are called primitives. Although primitives vary a bit from 3D application to application, most include a cube, sphere, cylinder, cone, and sometimes a pyramid. |
Spend Quality Time on 3D Lighting Spend quality time on lighting, as good lighting can bring the most boring of models and textures to life, or it can kill the most vibrant of designs. Again, render often here. During the lighting phase, you may find that the mood lighting you use is dulling the colors of the textures, so be sure to adjust the textures. |
Carving Out 3D Modeling Basics When somebody qualifies a digital character design as "excellent", it can be so in a lot of ways: 1) It is just a good design, 2) he carefully used the same shape for all parts of the body, and 3) this same shape is composed of some very simple geometric three-dimensional elements. Because he carefully designed the character, he already has a great idea of how to construct the character. |
I have seen many friends spend so much time creating perfect models that they never get around to texturing or animating the model, and end up with a portfolio full of models but no finished projects. Will the backside of the model ever be seen? |
Even more powerful is the ability in many programs to make duplicates that are mirror figures of the original. This cuts the modeling time in half for many objects like the human body that are essentially symmetrical in composition. When duplicating objects, 3D applications create another object that is a clone of the original; this includes all the polygons that make up the object. |
Now with all those definitions laid out in a linear fashion, I am going to tell you how the 3D creation process is anything but linear. We find a quasi-linear nature of the 3D process. The first step to a 3D project is to plan, plan, plan. I know, everyone wants to jump in and get started right away, which is an important thing to do when just beginning in 3D, but sooner or later, you will want to actually create an entire project. In my experience, every hour spent developing effective plans for a project saves 10 hours in actual production time. A large part of the planning process involves numerous drawings. |
Rotating 3D Objects in an Axis Defined Space An important part of the rotation process is the ability to move the object's axis and thus effectively change the axis of rotation. Imagine you have modeled an arm. Now, if the Rotation tool were used to rotate the arm, it would rotate around the geometric center of the arm. |
Positioning 3D Objects in the Axis Defined Space Most 3D applications have a sort of virtual toolbox with iconography representing different types of tools. Some tools are for moving objects, some for resizing, others for rotating, and still others for altering polygon structure and a host of other functions. |
Interpreting 3D Space on a Two-Dimensional Plane When a 3D application shows us shapes in 3D space rendered in perspective, it is interpreting space on a two-dimensional plane. Since our mouse can only move in two dimensions across the plane of the screen, if we simply reach in with our mouse and grab hold of the object with a move tool and attempt to move it, the 3D application makes its best attempt at interpreting which of the three dimensions you want to move the object through it's two-dimensional mouse movement. |
