Drawing hair with Inkscape


My very first online tutorial is an adaption from Chris Design Drawing Hairs article using both Path and Path Editor tools which requires Inkscape 0.47 or newer. Start-up Inkscape application which should open a new blank page and set the document into landscape.

 Create a path

  • Select the bezier tool or press either Shift+F6 or B on the keyboard.
  • Draw a line to approximately 800px or more. You can also use rectangle tool (R or F4 as shortcut key) as a thin line illustrated in grey.
  • While the line is selected, convert into path from the menu Path -> Stroke to Path or press Ctrl+Alt+C on the keyboard. For the rectangle, Path -> Object to Path or Ctrl+Shift+C. The result will show grey diamonds on each corner.



Create a pattern

  • On the menu, Extensions -> Modify Paths -> Add Nodes. Set the Max Segments Length to 5px.

  • On the menu Extension -> Modify Paths -> Jitter Nodes. Leave the default settings and apply effects.

  • You will have about thousands nodes which can be reduced with simplication (Path -> Simplify or Ctrl+L)
  • Resize the new generated patterns to about 20px width and 200px height, copy one of them with Ctrl+C or Edit -> Copy.


Setting a path effect

  • Create a new curve using bezier tool mentioned above and select it (bow anr S curve below).

  • We will use a path effect editor which can be accessed thought either Path -> Path Effect Tools or Shift+Ctrl+7. This editor should appear docked on the right side of Inkscape application.

  • With either a bow or S curve selected, apply new effect by choosing “Pattern along path” inside the list field and press Add. Pattern along Path should be listed inside Effect List.
  • Inside Current Effect field, you can either paste your created path or link to path which give finer control of the pattern we created earlier.
  •  Notice the path is horizontally stretched  giving a strange result illustrated above. To fix the issue, check "Pattern is vertical" inside Current Effect field.

  • Now we got a mesh that looks like hairs. To finalize, we applied the same effect on the S curve. If you have linked the pattern, you can adjust its width.


  •  With more practice, you can create a nice hairstyle with a combination of clipping.

 Happy drawing and leave feedback about mistake or other stuffs. A big thank you Máirín Duffy (Mizmo) for encouraging me to write this tutorial.

Using AMD RX Vega driver OpenCL on Fedora 29

The Raven Ridge APU is very capable processor to handle OpenCL inside some applications like Blender, Darktable and Gimp. Unfortunately, the current implementation from Mesa, clover, stuck to 1.3, is not supported. AMD released their driver 18.40 with OpenCL2.0+ targeting only Red Hat Enterprise Linux/Cent OS 6.10 and 7.5 in addition of Ubuntu LTS. The good new is the former rpm format can be used on Fedora.

The graphical part of Raven Ridge is Vega 8, basically a cut-down of Vega56 or Vega64 meaning choosing either driver for RX Vega.
The instruction is provided for extracting the rpm files but here is
 some requirements for OpenCL:
kernel-devel (provided by Fedora repository)amdgpu-dkmsdkmslibopencl-amdgpu-proopencl-amdgpu-pro-icd Once done, applications needing OpenCL will automatically detect the driver located on /opt/amdgpu/lib64. Blender will list as unknown AMD GPU and Darktable will enable it.



There is a ROCm version but it currently does not support the graphical side of Rav…

Improving HP Envy x360 convertible on Linux: the missing accelerometer driver

If you own an HP laptop equipped with AMD processor, you may find out the auto-rotation will not work as intended. It turned out that sensor is missing a driver not currently available on Linux kernel using the lspci -nn command from the terminal

03:00.7 Non-VGA unclassified device [0000]: Advanced Micro Devices, Inc. [AMD] Device [1022:15e4] That driver in question is AMD Sensor Fusion HUB. Unfortunately, researching it turned out harder even on AMD own website. Bug is already filed without answer yet from one of AMD representative.

Detailing the installation of AMD OpenCL rpm for Fedora

Revisiting the previous blog and freshly reinstalling Fedora Design Suite due to a busted boot, I look at the official guideline from AMD Driver for Red Hat Enterprise Linux 7.2 and write a way to improve the process of installing on Fedora 29 in this example.



Extracting the tarball contains the following:
amdgpu-installamdgpu-pro-install symlink to amdgpudoc folderrepodata folderRPMS folder containing rpm package
Executing the command ./amdgpu-install -opencl=pal --headless sadly failed on Fedora on that line:

./amdgpu-install -y --opencl=pal --headless

No match for argument: amdgpu

Upon closer look, the script failed to created a temporary repository on /var/opt/amdgpu-pro-local probably explaining why amdgpu metapackage name failed to display. Someone should investigate and provide a fix. At least, we find out Fedora support is available but unofficial.

Due to its design, Gnome Software only allows one cli…
