Select one:

True

False

Question 4

Given the following code segment, what do the values of X,Y,Z in the code need to be in order to generate a polygon that is an equilateral triangle?

var myGeometry = new THREE.Geometry();
myGeometry.vertices.push( new THREE.Vector3(0, 10, 0) );
myGeometry.vertices.push( new THREE.Vector3(-5, -0, 0) );
myGeometry.vertices.push( new THREE.Vector3(X,Y,Z) );
myGeometry.faces.push( new THREE.Face3( 0, 1, 2 ) );

Please enter your answer as the required X,Y,Z values.

Question 5

A single real value that represents the projection of one vector on the other and its

value is the product of the lengths of the two vectors times the cosine of the angle between them is called the ____ Answer.

Explanation / Answer

Q1)  In computer graphics, colors are specified by determining the amount of the primary colors Red, Yellow, and Blue. - TRUE [Any color in Computer is denoted by (R, B, G) ]

Q2) What is the shape of the polygon that the following code will produce? - TRIANGLE [We have first Point on Y Axis (X and Z are 0) and next two Points on X Axis (Y and Z are both 0).

Q3) In an orthographic view, objects appear to become smaller the further they are from the viewpoint? - FALSE (

Reason - Orthographic projections are often used when we want to be able to accurately compare the size of two objects, no matter how far each object is from the viewpoint (this is useful, say, in architecture or computer-aided design). Perspective projections are often used to reproduce what a human eye would see from a certain viewpoint in a 3-D scene, where objects appear smaller the further they are from the eye.)
