fix: Fix X-axis flipping issue

[Quanta-Naut]

I discovered issue where the rendered name appeared flipped and also the entire x-axis being flipped. This was caused by the x-axis being inverted during rendering. I’ve made the necessary adjustments to correct this behaviour.

The Last PR had conflicts so closed that, and now created new PR, to clean up.

needs proof of fix with asymmetric positioning, with symmetric positioning it's impossible to know if the texture was flipped or reflected

create 3 leds, each led should have it's position in it's name L0_0, L5_5, L5_0 (i.e. LX_Y)

[Quanta-Naut]

Ahhhh, that would be a better way to test it, will do that.

@seveibar the test is failing because the font is different in the test environment, took a while to figure that out, let me know if I can fix it. Thanks.

• need to show bottom side texture
• it's still unclear if the model or texture is being flipped but i suspect the entire model is being flipped based on the code.

[seveibar]

yea if you're flipping the entire model (which might be ok) a post-transformation fix is not appropriate

[seveibar]

basically there's a bug somewhere in the code with how the orientations are originally being created. Instead of fixing that, you're just flipping them all (which is inefficient and confusing!)

@seveibar sorry for the delay, had my exams going on. You were right about the bug, I removed the extra layer of transform and focused on fixing the bug, and also added the top and bottom view of a sample circuit.

[seveibar]

the transformMesh function is now "lying" and manipulating the input translation. You should be able to flip the texture without flipping the mesh

[seveibar]

@Quanta-Naut i investigated flipping the texture in https://github.com/tscircuit/circuit-json-to-gltf/pull/69/files

It doesn't work- you're correct that the X axis needs to be flipped but your placement of that flipping is not correct. But the good news is your approach is correct

[Quanta-Naut]

@seveibar Thank you for the confirmation. I have a doubt tho, by wrong placement you mean withing the geometry.ts file or the bug must be fixed in a different file??

@Quanta-Naut this was patched yesterday!
