I don't feel qualified to dictate the software needs of everything and everyone in the industry, i might expand a bit on what i'd like to see from such a system.
For a hair system ? *) First off, it should be able to stand on it's own without ICE. *) it should probably work on its own engine (like yeti, i assume). *) If it has its own engine, it should be open so as to offer TD's and Dev's the freedom and space they need to solve problems and expand tools or implement new tools. (this point is more a given, TD's and Dev's should always be facilitated in this regard). *) It Should have its own unit, like a strand, guide or null, that exists for this purpose. *)It should be tablet compatible, as in stylus, pen pressure, all that jazz. *) It should be ICE compliant ; stand on it's own yes, but that should not subject isolated from ICE, it's too good a tool to be ignored. Ideally, a relationship where ICE is less of a crutch and more of a third arm. e.g The proprietary Guides/strands/units can be brought into ICE as data, so if you where making a wood nymph, and you wanted to make flowers bloom from the tips of her hair: all this managed through ICE. Listening to Paul Smith, in his demo of FUZZ, he says that strand collisions are very slow. So regarding hair, ICE would be more an aesthetics effects base tool then a physics engine, the actual simulation being taken care of by the hair systems dedicated engine. so yes as much compliance between the two systems as possible. *) UI integration. where would it live ? i'd love to see the sparsely inhabited paint tools panel, be sectioned into 3 tabs, similar to the right side, MCP/KP-L/PPG. Tab 1: the original xsi paint tools, weight painting etc... Tab 2:... maybe some sculpting tool implementations :P ? (for another time !). Tab 3: The new hair system panel, including as preliminary features: 1) A stylus pressure segment with curve profile. 2) A layer system like the "scene" one in the KP/L so you can have separate hair systems on different hide-able reference-able layers, with the addition of a slider enabling you to increase or decrees the number of hairs shown in the viewport per layer. (this would allow you to rapidly test incremental density simulations, on the fly without having to dive into an ice tree or bring up a ppg ). 3) I'm a big fan of the M tool in SI, i love the 3 small grey icons that appear at the bottom of the view port, (manipulate, magnet and weld) i just wish it was customisable with even more tools ! In this spirit i would like to have a small library of icons on the hair system panel, icons for guide painting, and manipulation: paint/erase grow/cut, brush/frizz,orient ...etc. i would like it to be possible to click and drag these icons into a small tray on the viewport like the M tool small grey icons. so you can have your own customizable loadout. 4) Convert To: a series of utilities that allow you to convert elements, primitives or meshes, into hair guides; so you can choose to draw a curve and then click "convert to" guides or strands, upon which you get prompted to choose an existing layer to add to, or to create a layer for this new hair element. if you choose a mesh like a rectangle, it would give you the options on how you would like the hairs to populate the inside of the mesh, by length? what density? etc... note: if you convert to a guide, them the elements will become guides, if you choose convert to strand then the elements will become hair in witch ever layer you put them, influenced by the closest guide on that layer. And that's it, these are some of the things i would like to see in a "heavier" hair system. I toyed with the notion of a node graph like yeti's but from what i could see of it so far, it is very linear, nowhere near as fun as ICE, so a cool idea, for visualisation but i'd have to see a little more matured version to be sold. i doubt anyone will ever implement any of this, this is just a lot of pipe dreaming, but that is my answer.
