Question 31

Multiple Choice

Provide an appropriate response.
-A quadratic Bézier curve is determined by 3 control points p0,p1\mathbf { p } _ { 0 } , \mathbf { p } _ { 1 } , and p2\mathbf { p } _ { 2 } . The equation is x(t) =\mathbf { x } ( \mathrm { t } ) = (1t) 2p0+2t(1t) p1+t2p2( 1 - t ) ^ { 2 } \mathbf { p } _ { 0 } + 2 t ( 1 - t ) \mathbf { p } _ { 1 } + \mathrm { t } ^ { 2 } \mathbf { p } _ { 2 } . Construct the quadratic Bézier basis matrix MB\mathrm { M } _ { \mathrm { B } } for x(t) \mathbf { x } ( \mathrm { t } ) .
