For Slate

I am the primary implementor and designer of the Slate standard libraries as well as the graphical interface system. This is where much of my current effort goes.

For Squeak

The SIMS framework

The SIMS stands for Simulator of Interactive Mobile Sentients. It's indended to be a simulation and game engine based on the general qualities of a MOO or the commercial game, The Sims.

Primary features:

• Totally modular AI system and actor construction.
• Hierarchical logic of places, and mappings to real-world coordinate regions.
• Full generic use of prepositions.
• More general than any commonly used Object-Oriented MUD, and of course you can script it in Smalltalk.
• Uses peer-based processing to manage the complexity of handling large worlds, instead of relying on a central server.

SIMS Feature Requests: Let me know here what you'd like to see added to the framework, I'll receive automatic email notices.

Proprietary

I've developed several client-server database-based applications for work-scheduling, task-management, and information-relational applications. For these projects, I was the sole developer, and wound up doing a lot of my own user testing, analysis, and proposals; it was a very interesting experience.

Old

I've written a lot of packages, but most are too old to post; some I'm positive I've lost over time. Here are some descriptions:

Various File-Editors and Viewers

Text: Formatted-text handling editors, using syntax description files to allow automated syntax-highlighting and syntax error detection for various file formats.

Wireframe Objects: Simple graphical interface for the creation and manipulation of points, lines, and polygons(triangles) in 3d projective-plane geometry. Multiple simultaneous customizable views. Outputs files in DXF with layer notation to distinguish special information.

Texture-alignment for Wireframes: Takes DXF files as input for a 'preview' version of the target graphics engine, with provision for loading, placing, and orienting textures for final editing. Allows a quick preview of textures before placement.

High-Performance 3d Graphics Real-Time Rendering Engines

• Features:
  • Textures: linear/ bi-linear/ tri-linear/ quadratic/ interpolated texture-mapping, mip-mapping (of all sorts), light-sourcing (point, line, and directional), phong-shading, 8/16/24-bit color, texture blending/ graining/ layering, hypertextures, procedural textures, dynamic shadowing.
  • Object-Types: polyhedra, convex hulls, NURBs, spheres, z-buffering, s-buffering, sz(?)-buffering, (?)-buffering, Qsorting/ merge-sorting of stuff.
• Applications:
  • A simple space-flight engine for a futuristic space-fighter simulator and game. Realistic flight kinematics and dynamics, including inertial momenta, gyroscopic effects, engineering systems, and a relativistic sub-light drive visual effect. Handles thousands of objects on the screen with little effort. Includes multiple color bit-depths, a virtual cockpit, and realistic real-time true projective-perspective planetoid-rendering effects.
  • An indoor/outdoor walk-around engine for a first-person role-playing game based on convex hulls of hypertextured polygons.
