Designing Computer Animation Software?

reversedNormal asks: "I would like to write a full fledged 3d-Animation Software package from scratch. Yes, I know, a VERY daunting and time consuming task. But I have a very good understanding of 3D mathematics, physics, and computer graphics in general, plus a solid foundation in computer programming. To give you an idea, this package will be similar to Maya, 3DS Max, etc... in many respects. The question is, what is the best programming paradigm to use for such a project? I have all of the major concepts, and relationships in mind, but refuse to write one line of code until I have a good design plan. How does a professional programmer approach this design task? Ultimately I would like to be able to tie it into any number of different operating systems, graphics API's (OpenGL, DirectX, etc..), and so on. What are some good ways to do this?"

"Essentially I want the core of the software to be written in Standard C++, and then be able to tie into the Win32 API, or X, or QuickDraw (etc.) for display and input. The main concepts, such as procedural 2D and 3D geometry, 3D geometric transformation, polygon modeling, NURBS modeling, subdivision modeling, keyframe based animation of parameters, motion capture control of parameters, physics-based animation, sound synthesis, texture-mapping, lighthing, rendering, and so on are generally abstract ideas that do not need to depend on (but can certainly take advantage of) any particular API or environment. Of course, the idea is to eventually visualize the abstraction onto the screen, allowing the user to interact via the 2D pointer and keyboard input, and ultimately rasterize it, which will mean turning to various operating system standards. It will also be open as a plugin host and have a built in scripting language. Any design suggestions? I know that this is probably the most intelligent audience to communicate with, and any feedback would certainly be appreciated"

Consider writing plugings

[youBastrd]

3DS MAX and Maya pretty much do everything under the sun. If they can't do it natively, third-party plugins are a good way to go. If you need some functionality that's not there, write the plugin, surely you've got the skills to do that. These products are very mature already, nevermind their popularity and the amount of training users have invested in them.

You've got an uphill climb if you want to write this thing from scratch.

Re:Scripting Language - try Lua

[null-und-eins]

Lua (http://www.lua.org/) is a small, fast, extensible language that is designed to be embedded into an application. It has already become a favourite among game designers. The idea is, that you extend it with new datatypes in C, such that the objects in your application become scriptable. Think TCL, just better. For a performance comparison, see http://www.bagley.org/~doug/shootout/craps.shtml. It beats both Perl and Python.
