Making a Quad Sphere: 3ds Max, Maya, & Cinema 4D

Wednesday, November 6th, 2013 by

We’re going to go over how to make a quad sphere in 3ds Max, Maya and Cinema 4D, for CheckMate Pro v2.

The default sphere is problematic because of the two poles. By itself, a standard sphere does not seem to pose any problems, but when it comes time to subdivide, the differences in polygon density at the equator and at the poles produces pinching, and squashes the sphere around the equator.

Comparison of a Polygonal Sphere and a Quad Sphere

Here are the spheres unsmoothed.

When the spheres are smoothed, they both deform in different ways.

You can see how the Polygonal Sphere’s smoothing causes problems once a shader is added.  Little ridges are created at the top of the sphere.

You can see the ridges with a chrome material applied also.

While the effect is subtle, you should be able to see the faint star pattern within the normal sphere at the poles where the lighting and reflections get distorted as the sphere is subdivided. Moreover, it can’t simply be fixed by removing every other edge that’s converging to that one vertex to make the pole faces quads. The distortion is a direct result of the fact that it’s a curved surface where the pole exists.

As such, a far better approach is to build a quad sphere, which not only eliminates this pole problem entirely, but is completely CheckMate Pro v2 compliant. Here’s how you can accomplish this quickly in each of the major 3D applications.

3D Models Swim Out of the Box on YouTube

Thursday, February 23rd, 2012 by

As we’re always on the lookout for good uses of TurboSquid’s 3D models, we were thrilled at the most recent sighting. A blog post by Future Media Concepts of Orlando provides a detailed account of how 3D animator Jean Marco Ruesta not only brought four TurboSquid models to life, but also how he pushed them outside the YouTube player’s boundaries to swim onto visitors’ screens.

 

 

The lifelike aquatic life starring in these online promotions included:

Lizard 3 Salamander by shiva3d

Moray Eel Model by Ryan Kittleson

Ruesta, who also teaches Maxon’s Cinema 4D at the New York School of the Arts, created the finished product using Cinema 4D and Adobe After Effects. Check out his work on River Monster’s YouTube Page as well as Shark Week on YouTube.

Once you’ve seen it in action, be sure to see the full blog post “How They Did It: Bringing Creatures to Life in Discovery Networks’ Online Promosfor all the details on how he made it happen.
