FieldTrip and rendering
Hello, im a begginer haskell programmer, I currently have a big graphics codebase in C/C++, but since i determined to code only in haskell that i want to continue my work in it, and after a quick look at FieldTrip several questions popped up on my mind. Here they are: Are there any plans to remove the OpenGL dependency on FieldTrip ? Is this desirable (i can argue that it is) ? Are there any plans to use Data.Colour insted of the current color module ? Are there any plans to include Bézier, B-Splines and NURBS geometry ? (these could go into a separate module) Are there any plans to add geometry manipulation functions ? Are there any plans to separate the image part ? (and how about developing a set a image 'noise generation' functions ?, something like a functional libnoise). I don't understand exactly how FieldTrip works because my haskell knowledge is no big deal, but i can see that vertices are being sent to the renderPrimitive (which i guess is a wrapper for the begin/end functions of opengl). Is there a triangulation scheme for the parametric surface being done in those lines ? If yes, is there any way to tune it ? Is FieldTrip still being developed ? Why is this mailing list so quiet ? Im sorry for the long list of questions, im guessing some of these are pretty obvious, and some are probably inconvenient. I promisse i'll try harder next time. Thanks for your time and appreciation.

No plans yet. Do you have any suggestions? Personally, I want to move away from OpenGL to a GPU-centric architecture.
Are there any plans to use Data.Colour insted of the current color module?
Russell has suggested making this switch, and I have no objection. I haven't looked closely at the colour library. Does anyone have experience using it with either OpenGL or GPU programs?
Are there any plans to include Bézier, B-Splines and NURBS geometry ? (these could go into a separate module)
Contributions waiting to happen.
Are there any plans to add geometry manipulation functions ?
For instance? CSG?
Are there any plans to separate the image part ? (and how about developing a set a image 'noise generation' functions ?, something like a functional libnoise).
Yes.
I don't understand exactly how FieldTrip works because my haskell knowledge is no big deal, but i can see that vertices are being sent to the renderPrimitive (which i guess is a wrapper for the begin/end functions of opengl). Is there a triangulation scheme for the parametric surface being done in those lines ? If yes, is there any way to tune it ?
Yes, parametric surfaces are automatically tessellated. The current scheme is just a placeholder. I'd like something a lot smarter in there, sensitive to viewing and to the nature of the surfaces.
Is FieldTrip still being developed ? Why is this mailing list so quiet ?
It's not active in current form lately. I'm building a new, GPU-centered foundation. - Conal
