 • For 3-D rotation, we need to pick an axis to rotate an object. • The most common choices are the x-axis, y-axis, and z-axis. X-Axis Rotation • The transformation for x-axis is obtain from equation of z-axis rotation by replacing cyclically as shown here: x -> y -> z -> x • Rotation about x-axis, we leave x co-ordinate unchanged. y' = ycosθ - zsinθ z' = ysinθ + zcosθ x' = x • Matrix equation is: p' = Rx (θ) * p  Y-Axis Rotation • The transformation for y-axis is obtain from equation of x-axis rotation by replacing cyclically as shown here: x -> y -> z -> ..read more

• Parallel projection methods are used by engineers to create and working drawing of an object which preserves its true value. • In the case of parallel projection the rays from an object coverage at infinity, unlike the perspective projection where the rays from an object converse at infinite distance. • Parallel projection can be categorized according to the angle that projection of direction plan. Transformation of Parallel Projection  • Parallel projection (are also known as orthographic projection) is projections into one of the coordinate plans. x = 0, y = 0 and z = 0 • The standard ..read more
