New version of SeExpr with User Interface Components and Apache License

[Andrew Selle]

Walt Disney Animation Studios is pleased to announce a new version of the SeExpr open source project, now containing reusable user interface (UI) components and licensed under the Apache License (http://www.apache.org/licenses/LICENSE-2.0).

 
SeExpr is an expression language used to procedurally create textures and instanced geometry.  Expressions, though essentially a mathematical concept, can readily be used to create artist directed procedural content.  SeExpr is currently used in the following areas: shading, painting, procedural geometry synthesis, and dynamic simulator control.

With the addition of UI components in this new release, visualizing expression results is now much simpler, reducing the amount of time spent on debugging expressions and prototyping new looks.

UI components include:

• an expression editor, with auto-completion
• a panel for control widgets supporting:
• sliders
• ramp widgets
• color widgets
• an image previewer to show results of evaluated expressions
• an expression library browser

Also included is a step-by-step tutorial using the new UI components for building an example editor for image synthesis.

We hope this is going to be really useful for everybody, and I want to thank Janet Berlin for all her hard work getting this code ready to release!
