ICE – Particle density

August 28, 2008 1d
Comments

Based on the number of neighboring particles, this compound can adjust the color around the boundaries of a particle cloud.
The range is calculated based on the number of points in the island, so a gradient is smoothly blended to the particle color.

This can be used in any region of the stack. Plug the Execute Color in one ICEtree port and you are good to go.
However if you want the color to update with the simulation, you must use this in the simulation region.

TC Sketch v1.1 – Grease pencil for XSI.

March 17, 2008 1d

Like the grease pencil tool for Maya, this tool allows you to draw with the sketch tool for 2d animation/per frame annotation, directly in the XSI viewport.
Changes V1.1

  • Assembled the XSI Bezier curve tool, CV Curve tool and Curve Text tool to be used from the TC_sketch PPG
  • Added the “edit frames” command, now you can move your frames in time, selecting a frame in the listbox and using the “up” and “down” buttons.
  • Added the code to work on linux system.
  • The current frame stays visible until the next frame.
  • The listbox now let you navigate/select frames to edit.
  • “Default frame duration” option in the setup tab was renamed to “Last frame duration”. So now it just affects the last frame of the animation.
  • Re worked the entire keyframing command

Features V1.0

  • Drawing mode Auto-keyframing (selectability/visibility).
  • Curves color and Visibility/Selectability overrides.
  • Curve editing The “nav slider” in the “Edit Frames” group is useful to edit/add curves to existing frames. Change this slider will jump the XSI timeline to where the sketched curve is in time.
  • Auto-select curves option will automatically select all the curves for that given frame.
  • XSI Brush tool and View Proportional Transform Tool can be called from the TC_sketch PPG.
  • The Sketch tool creates a standard XSI curve, so you can use any XSI deformer tools on it.

Little animation for Nike. Did simulation, rendering, everything in XSI.
Compositing and creative direction by Nervo.tv

Simulation was really fun to do, the rigid body solver worked perfectly with a bunch of groups, two environments and animated RB constraints.
