First, thank you for sharing the code!

I'm having trouble with rendering the body/head, at the moment only the hair is rendered. There are no errors or warnings. Is this because I don't have the transformed body model yet? How can I transform the "Low Poly Base Mesh .obj" such that I can use it as the expected "female_halfbody_medium.obj"?

Looking forward to any suggestions, thank you.

Hi - I downloaded OpenMesh 6.3 but this error occurs when I run make:

Hi,
http://www-scf.usc.edu/~liwenhu/SHM/database.html cannot be reached now. Is there other available way to get the source hair data? Thanks!

My opengl version is 3.3. glfw version is 3.3. The rendered image is back at times . What's the problem? Thanks very much.

I rerun the command, It's ok.

Hi, thank you for providing us such a convenient tools for generating 2D hair tangent orientation fields.

However, when I look up the source code in the Renderer.h file, I find that you applied a "color[0] = x / 2.0 + 0.5;" operation at line #210. Could you please tell me the reason why?

I can infer that after doing "x = x/norm" and "y = y/norm", we got the sin and cos values of the orientation angle. And those two values could help us to compute the tangent value of the angle.

How to compute the 2D orientation field from RBG image? What are the parameters of the gabor filter?

Thanks for your contribution. How to construst the coordinate system in .txt (the rotation (Euler angles) and the position of the head)? If I want to construct the ellipsoids, how to do it? When we render the training data, how to rotate the ellipsoids according to different views? Thank you very much.

343 hair models from http://www-scf.usc.edu/~liwenhu/SHM/database.html is not available online anymore.
anyone have a copy of it?

Hi, I was recently reproduce HairGANs using the USC Hair Salon dataset. Since I wanted to reduce the aliasing of the 2D orientation map, I tried to render wider hair strands.

I set glLineWidth but it didn't help. Could you please give me some suggestions about this?

Many Thanks!

hi, thanks you for contribution of so awesome works,
when i try my best to compile the environment and run ./Hair_generate_convdata_and_imgs, only convdata was generated but no any renderd images were generated, and no any warnings or errors were found, the following is my snapshot:

are there any problems?
thanks, hope your reply much

I met the problem Segmentation fault (core dumped) when I running the programm HairMix_run.

hi, thanks your work very much
original hair has 10,000 strands , each strand with 100 or 0 3d points, ./HairMix_run will generate hair with 10000 strands but for each strand，in addition to 100 and 0 points, there are other different num points （such as 37 or 33 points ....）,
Can the generate-data be used directly for training?
