RectAreaLights

[michaelsakharov]

Do the Rect Area Lights work in your port yet? Also, this is a great project! It took me a while to find it but this is by far the best Threejs port to .net.

[michaelsakharov]

Looks like RectAreaLightHelper isn't Implemented

[michaelsakharov]

Did a bit of work and managed to get them Semi working, so it looks like all the code was there just missing the RectAreaLightHelper which I just ported over, I'm not really sure if I ported it over correctly, as it appears to be the more complicated of the Light Helpers. and I don't really know Javascript all that well.

[michaelsakharov]

Not sure what this weird Pattern is.

[michaelsakharov]

Really not sure what could cause this

[michaelsakharov]

Commenting out like 61 in the Lights_Physical_Pars_Fragment.glsl shader fixes it, so its something with Specularity

[michaelsakharov]

Implemented the LTC Textures that were missing, I'm guessing thats the problem. Not sure if I did it wrong though, there's definitely something still broken.

[michaelsakharov]

Im thinking its most likely the .png format im storing the LTC files in. Needs another format i think...

[michaelsakharov]

Hmm, I think I have hit a roadblock for me at least. Not sure how to get the LTC images in, While maintaining the correct pixel data, especially with Bitmaps, I don't know if they even can store floats.

[michaelsakharov]

For now disabled the LTC stuff in the shader, this works well enough

[michaelsakharov]

RectAreaLights seem to cause a Memory Leak, its Generating Infinite Textures. Might be related to the LTC's

[michaelsakharov]

And fixed it.

[hjoykim]

OK!, good How did you that?

[michaelsakharov]

I didn't manage to fix the LTC, But the Memory leak was a mistake on my side it was constantly trying to load the LTC textures when it should have only done it once.
