Default Invalid question in SM Quiz

Which of these is NOT a component of a NURBS object?

Hull
Vertex
Edit Point

Your Answer: Edit Point
Correct Answer: Vertex

Your answer was wrong

Trick Question???

the 3 responses are are all part of a nurbs object. CV's or 'control vertices' are a type of vertex. I know maya may explain it differantly and i dont mean to be anal about this. But, a Non Uniformal Rational B Spline consist of a variable number of vertices to plot a curve. By definition CV's are a type of vertex, though maya has named this strictly to polygon, and 'CV' to nurbs.

hehe i guess i just want a better score LOL..

Oh dear, i've just crossed the line to my anus..

When you right click on a nurbs surface and select a component mode, Vertex is not an option. Control Vertices, on the other hand, is.

A "vertex" and a "control vertex" is not the same thing. Mwa ha ha!

a vertex is a point of intersection between 2 or more paths. a control vertex is an intersection of two control paths that calculates the shape of a B Spline. this is the true definition in regards to Nurbs identification regardless of what some documentation may say. CV's are vertexes/verticies. Feel free to prove me wrong if you think you can. MWaaaaa hahaha hahahaha ahahahahaha LOL

Sure I can. Just right click on a nurbs surface and see what choices you get. :p

A vertex is a point in 3D space with a particular location, usually given in terms of its x, y, and z coordinates. Two vertices, taken together, can be used to define the endpoints of a line; three vertices can be used to define a planar triangle.

A CV itself (Or Control Vertice) is used in NURBS to define a mathemathical function that designates the way a curve will be pulled between her edit points.

As you can see the two terms are different.

listen. a vertex is a vertex man. you can claim all you want, but go for a mathmatics degree and see if you pass thinking that a control vertex is not a vertex. This is Nurbs.. a mathmaticaly calculated object, just saying that a maya menu doesnt have it doesnt make it not exist or change its definition. you can make these non substancial claims all you want, but i brought definition. If you can't dispose my statements, that ok. No ones perfect LOL. ADL pulls strong argument but, definatly in my favor. 3 or more verticies not only define a planer triangle, but are the minimum number of verticies to define a curve LOL...

This is becoming a really interesting post...

Come on dont give up now. Mwaa haha hahah haha
