Get distance between two points

Question was simple. Get the world position of any item in space throughout the entire timeline, then compare each point to get the frame-by-frame traveled distance.

With pymel, first get the item:

import pymel.all as pm
item = pm.selected()[0]

Get the frame range and turn off cycle check:

start_time = pm.playbackOptions(q=1,animationStartTime=1)
end_time = pm.playbackOptions(q=1,animationEndTime=1)
anim_range = range(int(start_time),int(end_time))
pm.cycleCheck(evaluation = 0)

Then, get its worldMatrix at every frame:

item_values = [pm.getAttr(item.worldMatrix,time=t)[-1][:-1] for t in anim_range]

To figure out the difference between frames, I didn't know how to do, so after some searching, this post had the most concise result:

https://stackoverflow.com/questions/1401712/how-can-the-euclidean-distance-be-calculated-with-numpy

And finally, the code needed to get the differences

per_frame_change = []
for i in range(len(item_values)-1):
    per_frame_change.append(numpy.linalg.norm(item_values[i] - item_values[i-1]))


Here's the whole code!

import pymel.all as pm
import numpy
start_time = pm.playbackOptions(q=1,animationStartTime=1)
end_time = pm.playbackOptions(q=1,animationEndTime=1)
anim_range = range(int(start_time),int(end_time))
pm.cycleCheck(evaluation = 0)

item = pm.selected()[0]
item_values = [pm.getAttr(item.worldMatrix,time=t)[-1][:-1] for t in anim_range]

per_frame_change = []
for i in range(len(item_values)-1):
    per_frame_change.append(numpy.linalg.norm(item_values[i] - item_values[i-1]))

MatchMoving!!

I've been researching a few techniques to fix my latest render file, so I've resorted to simply re-doing the MatchMoving (the technique to match the camera to a cg environment).  I'm hoping that this helps me with my scene!

This is the tutorial that I found:

I'll upload my findings later :)

New Reel!

So, ladies and gents, here's my brand new Demo Reel! It's only 2 shots, but I feel they are nice enough to post on my site as finals. Enjoy! :)

Maya Update: First Animation

So, we started the animation part of the Maya Springboard program. I had fun animating this first animation for, well, AnimationMentor. But first, an update on my last scene. I think it came out ok :) What do you think?

And here's the video. It's a playblast.

Maya, here we come!

So, I recently began the Maya Springboard Program; a.k.a. massive Maya learning experience. Here's the resulting product of 1 week of work in Maya. First, I made the character (no joints, bones, or anything technical) out of pure geometry, and I think it came out ok for someone that doesn't do a lot of modeling.

Then came the Scene. Here's some screenshots. I'll be adding a few more things to it every day I learn something new.
