Name

PEXBuildTransform

Synopsis

void PEXBuildTransform(PEXCoord ∗fixed_point, PEXVector ∗trans_vector, double angle_x, double angle_y, double angle_z, PEXVector ∗scale_vector, PEXMatrix matrix_return)

Arguments

fixed_pointorigin for scaling and rotation

trans_vectortranslation vector

angle_xangle of rotation about X axis, in radians

angle_yangle of rotation about Y axis, in radians

angle_zangle of rotation about Z axis, in radians

scale_vectorvector of scale factors for X, Y and Z

matrix_return
matrix into which result is stored

Returns

None

Description

This function builds a transformation matrix that scales by the values in the scale vector about the fixed point, rotates about the X, Y and Z axes using the fixed point as the center of rotation and then translates according to translation vector, in that order. 

Errors

None
