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

Usemakehgtformto create transform matrices for translation, scaling, and rotation of graphics objects. Apply the transform to graphics objects by assigning the transform to theMatrixproperty of a parent transform object.

M = makehgtformreturns an identity transform.

M = makehgtform('translate',[tx ty tz])or M = makehgtform('translate',tx,ty,tz) returns a transform that translates along thex-axis bytx, along they-axis byty, and along thez-axis bytz.

M = makehgtform('scale',s)返回一个尺度变换统一thex-,y-, andz-axes.

M = makehgtform('scale',[sx,sy,sz])returns a transform that scales along thex-axis bysx, along they-axis bysy, and along thez-axis bysz.

M = makehgtform('xrotate',t)returns a transform that rotates around thex-axis bytradians.

M = makehgtform('yrotate',t)returns a transform that rotates around they-axis bytradians.

M = makehgtform('zrotate',t)returns a transform that rotates around thez-axis bytradians.

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

Note that you can specify multiple operations in one call tomakehgtformand 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

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