| Thanks very much Alain for helping teach Seamless I am truly indebted to you to answer your question about using references for the hairs, you could do this like I show in this tutorial “Duplicating Objects Using References” http://www.seamless3d.com/tut/ref_obj but I prefer here to keep each strand of hair individually generated by nurbs so that each strand can be controlled individually. Referencing can reduce file size significantly but I don't think it will make things render any faster. I have been thinking more about those images you showed Alain where you get the same type effect I have been getting with my hair just by having multiple lines running in parallel. I wonder if each strand of hair was coloured slightly different if this would help. Speaking of textures, the new version of seamless will let the artist paint inside the 3D window using a brush much like a typical 2d paint program but you will be able to paint 3d objects directly. I don’t know if this tutorial will be of any help to samd: http://www.seamless3d.com/tut/texture_mapping/ | |

Yes I remember Alain , this was all made before seamless used nurbs or bezier curves, it would be fun to try making braids and a horse again using stitched nurbs patches, should be a lot easier however one can never be sure until one has tried. The circular bend (CCBend) I used back then may have been advantages for making braids. Revisiting my spaghetti hair, I increased the number of strands from 149 to 258 (each strand planted by hand), decreased the diameter to 1 mm and made it semi transparent. Thinner strands reduces the fullness but despite this I feel it looks better. I am very happy with how the transparency gives the hair a softer more hair like appearance | |

| I can obsess about anything Alain especially when I am allowed to spend all my time focusing on a problem. I added some more hand planted strands bringing them to 300 and then quadrupled them using my algorithm bringing the total number of strands to 1200. Took Povray 2 hours and 41 minutes to render but would have been a little faster had I left Povray the main focus for the entire time. | |

| After rendering this hair last night I felt very happy Alain that I had finally got a full head of hair that has a nice soft appearance. (I had done tests before with dense hair that looked horribly like the strands were made of wire). However when I look at the previous picture posted here I can see how you loose being able to see all the individual strands of hair when you have a full head of hair but I can understand this may be only due to myself looking at hair and analysing how it looks for too long lol but it would be nice to render a movie with far fewer strands just for the time it takes. It seems though the next generation of video cards will be able do all this and more in real time. This advertisement from NVidia shows their latest video card ray-tracing water and glass reflections in real time (no time waiting for the computer to render the image):
https://www.youtube.com/watch?v=um6rMjwSNdU
So seems the processing power is just around the corner to be able to ray trace my hair in a fraction of the time.
Just a few months ago before I started developing the new hair node, I made it so I could plot a pixel on a 3d textured object where ever I clicked (this was surprisingly easy to do) and then I made it so I could drag the mouse to plot a line of pixels. The next thing to do is make it so you can set a radius for the paintbrush and have the pixels fade out like a spray can feature which you will typically find in a 2d paint program. I have already done this for color per vertex painting (not online yet), so there should be nothing too challenging left for me to complete my texture painting feature. However I have taken on quite a few major challenges for the upcoming version that are not yet fully resolved so I must try hard to not take on any new ideas or I will be unable to complete it before the end of the year lol. If you are eager to test any feature out before it is ready, please let me know and I will see what I can do to upload something that can be played with before all the new features have been fully resolved.

I think life will be so well simulated it will hurt when your avatar falls Because this looks quite nice I thought I share it before I ruin it There are 1200 non transparent strands randomly distributed by the computer. The shape of the hair is controlled by 3 nurbs patches. | |

| Thanks Alain If I only had to make Punk hairstyles life would be easy lol This was my first attempt to cover the rest of her head the same way I added the first band of strands on the top. I quite like it but it looks rather like a furry hat to me: A different approach to complete covering the head by adding clumps of hair one at a time which seemed to get better results but it proved time consuming making each clump fit on the scalp: I decided instead of adding individual clumps of hair, to instead try beginning with the whole scalp planted up so as to bypass the time it takes to make each clump fit on the scalp. This picture shows 4400 strands planted randomly all over the region of Lucy’s scalp waiting to be stylised: I thought just the parting of the hair with this new approach to form the fringe was interesting enough to share : Here is my first real hairstyle derived from the 4400 straight strands radiating from the scalp: Here is a variation where the fringe is broken up into spiky locks making it look more wild: | |

| I am always flattered when you want to use any of my stuff Alain Many triangles are needed to generate this hair for Lucy. Sometimes I wish we could just use veils like this pretty Syrian girl: http://www.travelblog.org/Photos/4341419 which looks very nice and would save on zillions of triangles The smls files containing all the nurbs patches that define Lucy's hair is 1.6 meg in size and when output to povray the povray files are 58 meg !!! This sounds like a krazy amount of triangles just for the hair but when I think how I only have 4400 strands of hair and the nVidia hair examples have 18000 strands rendered in real time it makes me feel justified in using this many triangles here in the West lol. I glanced through the pdf file from your link. This hairball seems to be used as an object to test “Ray-Cast Ambient Occlusion” rendering. This hairball is indeed a strange object, The strands look much like thin pieces of bamboo or wood and I notice many of them going through each other but what's really strange is it looks like holes are made for the bits to pass through each other. Why is this done? I do not know lol | |

| Hi Alain Just to keep you updated with the progress of the new hair feature. I have been developing a feature that allows the user to define regions so that the hair strands can be grouped for the locks. The regions can be selected and seeded with any density of strands: Simple long straight hairstyle utilising poly regions: | |
