How copy WebGLTexture to pc.Texture?

Hmm, good question, pc.Texture is a wrapper to feed to the device/forward renderer the texture source info.

I don’t have an answer on this, but you can check the device.js source file on how it runs gl calls to bind the textures. Might be a good starting point on how to get from there to pc.Textures.

I find other way and get raw pixel data instead WebGLTexture

This is not native PC, 8th wall camera image for processing effect

Hey chaps, any further info on this one? I’m trying to forge a path forward towards capturing raw camera pixels during a WebAR session, and feel this is the last remaining hurdle…

Cheers,
Isaac
