Description Paul Geraskin 2014-02-03 10:50:32 UTC

Hi guys.

I would like to get NormalMap generator. It's NVidia Tool. It can do cool NormalMaps(It's like bump maps, but they are for 3d video cards (BLUE TEXTURES)) and create DDS files (they are like PNG, but optimized for video cards).
THE CODE: http://code.google.com/p/nvidia-texture-tools/
NVIDIA PAGE: https://developer.nvidia.com/nvidia-texture-tools-adobe-photoshop

You can check gimps plugins which added the Nvidia Textre Tools.
http://code.google.com/p/gimp-normalmap/
http://code.google.com/p/gimp-dds/

This generator is added to Photoshop and Gimp as plugins. It would be cool to add it to Krita too.

The Tool can do:
- Generate normalMaps
- Load/save DDS files.

Moving this to filters, couldn't find it initially :)

WISHGROUP: Larger Usability Fixes

Amadirow as originally working on this. We need to take the phong bumpmap code that takes our heightmap; we we should stop half-way the code in that filter.

Git commit c9583d1562353662fc46e077786b8590eaa5ad08 by Wolthera van Hövell tot Westerflier.

Pushed by woltherav into branch 'master'.

Feature: Height to normal map filter.

This adds a height to normal map filter to Krita.

The filter is based on the edge detection filter, so like it, it
can do prewitt, sobol and simple, as well as have a editable kernel
radius(which controls how strong the effect of a height difference is in the
resulting normal map), and it can be used as a filter layer/mask/brush.

The most common used method is sobol with a single px radius, which is also
the default it open up on.
