Name

odielib::math - The Odielib Accellerated Math Module

Table Of Contents

Synopsis

  • package require odielib 2.0

Description

The math package is included with odielib. It contains a series of C-accellerated routines for matrix math, tailored for graphics and basic (i.e 3 dimensions and time) physics.

COMMANDS

affine2d::combine transform transform ?transform...?

Accepts N 3x3 affine matrices, and returns a 3x3 matrix which is the combination of them all.

affine2d::rotation_from_angle theta ?units?

Computes a 2d affine rotation (a 3x3 matrix) from an angle theta.

Valid units r - radians (2pi = one turn), g - gradian (400 = one turn), d - degree (360 = 1 turn)

affine2d::rotation_from_normal normalx normaly

Computes a 2d affine rotation (a 3x3 matrix) from a directional normal, given my %of travel in X and Y.
