Your online Softimage Educational Resource

The blog has been online for more than 4 years and there’s still not a single post even remotely related to the delicious brew called coffee… Perhaps it will someday, but in the meantime you can read the articles about Softimage. Most of the material are tutorials and Q&As I’ve written for 3D World Magazine sometime between today and 2003. If you have any questions please don’t hesitate sending me an email.


Thanks to Letterbox Animation Studios for hosting all the scene files.

Simulating an effervescent tablet using particles

Step 01
Creating particles
The first think you’ll need is obviously a glass of water and a tablet, so start by opening the scene effervescent_tablet.scn from this issues CD. Press [4] to switch to the Simulate toolbar. Select the tablet and from the Create > Particles menu choose From Selection. In the particle PPG, change the settings as shown in the above screenshot (a high-resolution version can be found on the CD).

Step 02
Adding bubbles
In the Particle_Billboard section, switch to the Make Connection tab and click the Sprite button. Switch to the Sprite tab (in the PType section) and click the New button > New From File... and pick the SpriteBubble.pic image from the CD. From the Get > Force menu, choose Gravity. Change the Amplitude to about 10. Rotate the gravity -180 degrees along the X-axis so it points upwards.

Step 03
Creating the environment
Select the cloud and from the Modify > Environment menu, choose Apply Force and pick the gravity object. With the cloud still selected, click Modify > Environment Modify > Environment > set Obstacle and pick the glass. In the obstacle PPG, change the Obstacle type to Actual Shape. Set a new obstacle but this time, pick the WaterSurface. From the Inspect > Events menu choose PEvent1 and, in the PPG, change the Action to Disappear.
