Arguments

xo,yo,zo
Point about which scaling and rotation take place

dx,dy,dz
Translation distances

angx,angy,angz
Angle of rotation in degrees

sx,sy,sz
Scaling factors

dep
The dependent shear direction

= GXAXIS,

X-axis

= GYAXIS,

Y-axis

= GZAXIS,

Z-axis

dir
The direction of the shear

= GXAXIS,

X-axis

= GYAXIS,

Y-axis

= GZAXIS,

Z-axis

a

Description

The routines gBuildMatrix2D() and gBuildMatrix3D() are called to build a transformation matrix containing a rotation, a translation, scale and optional shear factors. The scaling, rotation, translations and shear factors are all relative to the point xo, yo, (zo).
