Description 

 

add

ClearTransform 

Resets a transform back to initial conitions. 

 

CosAngle 

Returns the cos (cosine) of the angle between two vectors. 

 

CreateNamedTransform 

Allocates and initializes a new transform for the user. if name is NULL, allocates an unnamed transform; otherwise the transform is created in a known namespace that can be browsed. 

 

CreateTransformMotion 

This is function sack::math::vector::CreateTransformMotion. 

 

crossproduct 

This is function sack::math::vector::crossproduct. 

 

DestroyTransform 

This is function sack::math::vector::DestroyTransform. 

 

DirectedDistance 

Returns the distance a point is as projected on another vector. The result is the distance along that vector from the origin. 

 

Distance 

Returns the distance between two points. 

 

dotproduct 

This is function sack::math::vector::dotproduct. 

 

Forward 

Sets the forward direction speed in a PTRANSFORM. 

 

GetAccel 

This is function sack::math::vector::GetAccel. 

 

GetAxis 

This is function sack::math::vector::GetAxis.

Invert 

Inverts a vector. that is vector * -1. (a,b,c) = (-a,-b,-c)
Parameters 

 

InvertTransform 

Badly named function.
InvertTransform turns a transform sideways, that is takes axis-normal transforms and turns them for sending to other graphic systems.  

 

Length 

Returns the scalar length of a vector. 

 

LoadTransform 

Recovers a transformation state from a file. 

 

Move 

Updates a transform by it's current speed and rotation assuming speed and rotation are specified in x per 1 second. Applies the fraction of time between now and the prior time move was called and scales speed and rotation by that when applying it. 

 

normalize 

Normalizes a non-zero vector. That is the resulting length of the vector is 1.0. Modifies the vector in place. 

 

PrintMatrixEx 

Dumps to syslog a current matrix. Shows both matrix content, and the cross products between the matrix that cross1 should be row 0, cross2 should be row 1 and cross3 should be row2. Pass a text name to identify this matrix from others. 

 

PrintVectorEx 

Logs the vector and leader to log. the leader is called lpName, cause it was inteded to be used by just the vector name. 

 

PrintVectorStdEx 

Same as PrintVectorEx, but prints to standard output using printf. 

 

project 

result is the projection of project onto onto 

 

Right 

Sets the right direction speed in a PTRANSFORM. 

 

RotateAbs 

This is function sack::math::vector::RotateAbs. 

 

RotateAbsV 

This is function sack::math::vector::RotateAbsV. 

 

RotateAround 

Rotates a transform around some arbitrary axis. (any line may be used to rotate the transformation's rotation matrix) 

 

RotateAroundMast 

Rotates around the 'up' of the current rotation matrix. Same as a yaw rotation. 

 

RotateMast 

Sets the current 'up' axis of a transformation. The forward axis is adjusted so that it remains perpendicular to the mast axis vs the right axis. After the forward axis is updated, the right axis is adjusted to be perpendicular to up and forward. 

 

RotateRel 

Updates the current rotation matrix of a transform by a relative amount. Amounts to rotate about the x, y and z axii are given in radians. 

 

RotateRelV 

Update a transformation matrix by relative degress about the x axix, y axis and z axis. 

 

RotateRight 

This is function sack::math::vector::RotateRight. 

 

RotateTo

SetSpeed 

Set the speed vector used when Move is applied to a PTRANSFORM. 

 

SetTimeInterval 

Set how long it takes, in milliseconds, to move 1 unit of speed vector or rotate 1 unit of rotation vector when Move is called. Each matrix maintains a last tick. If many thousands of matrixes were used, probably a batch move could be implemented that would maintain tick counts for a group of matrixes... don't know how long it takes to compute move, but timeGetTime will slow it down a lot.
