@Telstra I am an existing Telstra user on a plan and am trying to pre order the iPhone 15 Pro. I get multiple errors when clicking on the "Agree to terms and do credit check" step. I think it is a Salesforce issue.

Haven’t gotten it on Vinyl yet, have been looking at it on Discogs for a while. But I did get the 30th Anniversary on CD last year.

To get a better understanding of Ray Marching and Sphere tracing I first worked it our in 2D using SwiftUI before moving to 3D with Metal Shading Language. #RayMarching #SwiftUI

I think it is important to show progress when coding, particularly the failures. To get the previous image I tweeted, I had to go through quite a bit of bug fixing and some rewriting. #RayMarching

Got my iOS Ray Marching Shader (MSL) working late last night. So far only spheres and diffuse lighting, lots more to come. Not quite sure why the horizon rises up to meet the orange sphere though🤔 Is using a SwiftUI wrapper to display #RayMarching #SwiftUI

Surprised that #SwiftUI Divider() view applies an opacity I can’t seem to override. The result of the following code is two different coloured lines.
Ray marched sphere, had one of my calculations backwards. #RayMarching #Metal #Swift

Getting back into learning Shaders again, this is supposed to be a RayMarched 3d Sphere 🤔 #RayMarching #Metal #Swift

Need to be careful using SVGs in Xcode. I may be doing something wrong here, but the SVG displayed on the left, doesn't look the same displayed in SwiftUI App on the right. The colours are different, and the swirly white layer is either missing or lost in compression. PNG works.
