Merge weBIGeo by adam-ce · Pull Request #234 · AlpineMapsOrg/renderer

adam-ce · 2026-01-20T12:45:03Z

No description provided.

- includes also buffer to texture node rewrite

- uv/position/weight calculations should be finally correct now

- for experimental implementation of multi-flow models using a sequence of compute shader calls

Note: Seems to be buggy for overlay texture

- convert our single-direction trajectory model to a monte-carlo method by randomly offsetting the sampled normal each step for simulating divergence/"spread" of the avalanche - still WIP, need to expose some parameters as uniforms esp. sample count and offset radius

- dispatch more workgroups instead of looping over samples in shader

- eliminates annoying white trajectories per default

What we did in the meeting.

@GeraldKimmersdorfer @pkomon how much badness does this cause in webigeo?

iirc this is necessary in the alpine app to place the pivot point for some of the interaction methods.

adam-ce

thanks for putting in all the work!!!

i reviewed only the nucleus and shared parts, i trust you on the webgpu parts. please see the in-line comments (also see the comment 1 hour ago, half a page up). i

adam-ce · 2026-06-30T09:45:12Z

delete instead of comment

adam-ce · 2026-06-30T09:47:35Z

well, use Q_ASSERT (https://doc.qt.io/qt-6/qtassert.html)

adam-ce · 2026-06-30T10:00:58Z

the opengl version uses nucleus::srs::pack(tile.id) -> glm::vec<2, uint32_t>, which is more efficient and works until zoomlevel 29 (according to chatgpt). i therefore think that this class should not exist.

if you want to keep it, please move it into webigeo. but i would rather suggest replacing it with pack and unpack.

adam-ce · 2026-06-30T10:01:59Z

the convention would be to remove the stb_ prefix from all files inside the stb directory.

adam-ce · 2026-06-30T10:20:12Z

you switched this file to windows line endings. fix your git setup, use linux line endings!

adam-ce · 2026-06-30T10:42:00Z

move this ktx setup to cmake/SetupKTX.cmake to clean up the main CMakeLists file. make a function that takes the commitish, and does the rest of the setup. this should be easy for an llm.

can we set the min version to qt 6.10 or 6.11?

adam-ce · 2026-06-30T10:59:31Z

i'm not against providing a cmake preset, but this one should be cleaned up.

there are hard coded paths, alp-base sounds strange in the context of the upstream repo, generally, there is a ton of targets.

imo:

remove the release stuff, and let CI build that (you can download the artefacts).

make targets like webgpu_* and webgl_*

remove all hardcoded paths (they will break at some point), and rely on the environment. if that doesn't work, instruct the user on how to specify it locally.

adam-ce · 2026-06-30T11:00:56Z

+## Code style
 * class names are CamelCase, method, function and variable names are snake_case.
 * class attributes have an m_ prefix and are usually private, struct attributes don't and are usually public.
-* use `void set_attribute(int value)` and `int attribute() const` for setters and getters (that is, avoid the get_). Use [the Qt recommendations](https://wiki.qt.io/API_Design_Principles#Naming_Boolean_Getters,_Setters,_and_Properties) for naming boolean getters.


why did you remove the link?

adam-ce · 2026-06-30T11:01:02Z

 * indent with space only, indent 4 spaces
 * ideally, use the clang-format file provided with the project
  (in case you use Qt Creator, go to Preferences -> C++ -> Code Style: Formatting mode: Full, Format while typing, Format edited code on file save, don't override formatting)
-* follow the [Qt recommendations](https://wiki.qt.io/API_Design_Principles) and the [c++ core guidelines](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines) everywhere else.
