Subject: [x3d-public] Tests for Blender->X3D exporter utilizing texture transformation and per-vertex colors<br>
<br>
Vincent and all,<br>
<br>
( Sorry it took me a while -- Christmas times are busy in offline<br>
activities :) )<br>
<br>
1. I prepared the promised tests of texture transformation in Blender,<br>
to help implementing their handling in the Blender -> X3D exporter.<br>
<br>
They are inside the "blender_tests/texture_transform/" of my<br>
repository <a href="https://github.com/michaliskambi/x3d-tests/" data-auth="NotApplicable">
https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fmichaliskambi%2Fx3d-tests%2F&data=05%7C02%7Cbrutzman%40nps.edu%7Cceba4b4d4c234122992d08dd26eec101%7C6d936231a51740ea9199f7578963378e%7C0%7C0%7C638709529230301171%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=ZO4iUotBKD2V31mqOuq6fm4inKTDis5C2%2FkxA2YSZtI%3D&reserved=0</a>
. Browse them<br>

. To just download them, it's probably easiest to "git clone" the<br>
whole x3d-tests repo.<br>
<br>
The README inside (<br>
<a href="https://github.com/michaliskambi/x3d-tests/blob/master/blender_tests/texture_transform/README.md" data-auth="NotApplicable">https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fmichaliskambi%2Fx3d-tests%2Fblob%2Fmaster%2Fblender_tests%2Ftexture_transform%2FREADME.md&data=05%7C02%7Cbrutzman%40nps.edu%7Cceba4b4d4c234122992d08dd26eec101%7C6d936231a51740ea9199f7578963378e%7C0%7C0%7C638709529230367342%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=Y4dgxu%2FKdWNDwq%2BPbA4NjYCvMQTVQKY9mL2piilbQww%3D&reserved=0</a><br>
) already describes everything. A short summary:<br>
<br>
- I tested transforming base, normal, metallic/roughness textures<br>
(same or differently).<br>
<br>
- I added a "real-life example" of using texture transformation (from<br>
Castle Game Engine "examples/fps_game" demo,<br>
<a href="https://github.com/castle-engine/castle-engine/tree/master/examples/fps_game" data-auth="NotApplicable">https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fcastle-engine%2Fcastle-engine%2Ftree%2Fmaster%2Fexamples%2Ffps_game&data=05%7C02%7Cbrutzman%40nps.edu%7Cceba4b4d4c234122992d08dd26eec101%7C6d936231a51740ea9199f7578963378e%7C0%7C0%7C638709529230389095%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=GDfn864P1Fy7yrtQcTapwre0BHqd5LUklaP1OFG3WTM%3D&reserved=0</a><br>
).<br>
<br>
- I added glTF exporter outputs, screenshots from Blender, Castle<br>
Model Viewer -> hopefully this all makes it clear what is the desired<br>
output.<br>
<br>
- TODO: I planned to do, but did not do this: I wanted to create a<br>
"desired" X3D files, crafted by hand, to show how a proper X3D output<br>
should look like. Not done yet, simply because of lack of time. I<br>
don't want to keep you waiting, so I send you the tests as they are<br>
now. Ping me if you think you need these "desired" X3D files :)<br>
<br>
2. Moreover, I added tests for per-vertex colors.<br>
<br>
This shows per-vertex colors generated using Blender's "Ambient<br>
Occlusion" (make areas e.g. behind ears nicely darker even without<br>
using real-time shadows) and how they can be multiplied with<br>
material(s) in glTF. This is a feature we talked about -- you<br>
mentioned you wanted to implement it by "premultiplying" the material<br>
* per-vertex color. Hopefully my tests will help make sure it's all<br>
correct :)<br>
<br>
They are in:<br>

<br>
Again, I added glTF exporter outputs, screenshots from Blender, Castle<br>
Model Viewer -> showing what should happen.<br>
<br>
I hope these are useful! Let me know if anything in this is unclear.<br>
