makehgtform - Create 4-by-4 transform matrix

Syntax

M = makehgtform M = makehgtform('translate',[tx ty tz]) M = makehgtform('scale',s) M = makehgtform('scale',[sx,sy,sz]) M = makehgtform('xrotate',t) M = makehgtform('yrotate',t) M = makehgtform('zrotate',t) M = makehgtform('axisrotate',[ax,ay,az],t)

Description

Use makehgtform to create transform matrices for translation, scaling, and rotation of graphics objects. Apply the transform to graphics objects by assigning the transform to the Matrix property of a parent hgtransform object. See Examples for more information.

M = makehgtform returns an identity transform.

M = makehgtform('translate',[tx ty tz]) or M = makehgtform('translate',tx,ty,tz) returns a transform that translates along the x-axis by tx, along the y-axis by ty, and along the z-axis by tz.

M = makehgtform('scale',s) returns a transform that scales uniformly along the x-, y-, and z-axes.

M = makehgtform('scale',[sx,sy,sz]) returns a transform that scales along the x-axis by sx, along the y-axis by sy, and along the z-axis by sz.

M = makehgtform('xrotate',t) returns a transform that rotates around the x-axis by t radians.

M = makehgtform('yrotate',t) returns a transform that rotates around the y-axis by t radians.

M = makehgtform('zrotate',t) returns a transform that rotates around the z-axis by t radians.

M = makehgtform('axisrotate',[ax,ay,az],t) Rotate around axis [ax ay az] by t radians.

Note that you can specify multiple operations in one call to makehgtform and the MATLAB software returns a transform matrix that is the result of concatenating all specified operations. For example,

m = makehgtform('xrotate',pi/2,'yrotate',pi/2);

is the same as

m = makehgtform('xrotate',pi/2)*makehgtform('yrotate',pi/2);
