About this page

Hi there,

This is the homepage of Joshua Leung (Aligorith) on Blender's Wiki. If you've followed a link from one of the 2.4x release logs here, scroll down to the "Completed Projects" section (or on these links to go to the logs for 2.43, 2.44, 2.46, or 2.47). This page has somewhat "grown" over the years since the time when those links were originally published, and now includes quick-links to various projects and notes I've written here over the years.

A bit about myself for the curious: I've been a Blender user since 2004, and a core developer since 2006. As you'll find on this page (and those linked from it), I'm the maintainer/developer of the Animation System and Grease Pencil, as well as laying the groundwork for the Bullet RigidBody integration, and work on other areas including the Outliner and Transform Tools.

Quicklinks while editing the wiki

Wiki Templates (Formerly at http://mediawiki.blender.org/index.php/Meta/Templates)

Useful Links for New Devs

• http://www.catb.org/esr/structure-packing/ <--- Extra reading about C structure padding, useful when dealing with SDNA padding errors

Quick OpenGL Links

• http://homepage.mac.com/arekkusu/bugs/invariance/HWAA.html <--- problems with OpenGL smooth + nice-looking lines
• http://www.graficaobscura.com/?/texmap/ <--- cool graphics dude's stuff
  • http://www.graficaobscura.com/dyna/index.html <--- OMG! this is so cool (but for irix only)
• glsl approach - http://www.mdk.org.pl/2007/10/27/curvy-blues

Projects Unfinished/Not being worked on

• Force Modifier

Ideas for Future Investigation

Cool Stuff

• Innovative Posing Tools
• Fixes Needed for Lib Linking/Proxies

Useful Stuff

• Generic Widget API - useful for things like drawing a "transform box" to define a region to edit (with handles to move/scale/rotate)
• Editable Bone Paths (kindof falls under cool stuff, though is more of a pragmatic issue)
• Better ghosting/visualisation of rigs (i.e. make it easier to have setups where you can just click on the mesh to select parts of the rig)

Unlikely to be implemented

• Animated Vertex Group Weights
• Vertex Groups for Curves
• Node-Based Editing of Constraint+Driver Systems

Obsolete/Work in Progress

Work overlapping with Animato in 2.5

• Record Performance
• Better Keyframing?

Abandoned Ideas

• Mesh Modifier <--- Implemented in 2.46 as MDef by Brecht
