laanlabs / arbrush Goto Github PK

The app crashes on view touch unless I change the pixelFormat in VertBrush.swift to pipelineStateDescriptor.colorAttachments[0].pixelFormat = MTLPixelFormat.bgra8Unorm_srgb

I'm on a iPhone 7, is this expected?

Can you please update the license?

I try to brush.clear() and clearDrawing(). It works, but if I draw after clear -> app fails without any information in log.

Something changed with metal / arkit to make this app no longer draw correctly for me. I'm on iOS 13.3

If I want to pan on the screen,not hold the draw button and remove the device,what should I do?thx.

Crash on touch iPhone 7+ iOS11

Cannot invoke 'SCNMatrix4.Type.init' with an argument list of type '(matrix_float4x4)'

any fix ?

I am trying to run the code on Xcode 10.1, iOS 11 and Swift 4. However, I am getting two errors in shaders.metal line 104 and 109:
line 104: no matching function for call to 'dot'
line 109: no matching function for call to 'reflect'
does anyone solve the same issue?
Please let me know if you have any idea how to solve them. thank you
