@SebAaltonen I saw some tweets a while ago about you using Flutter for UI and it looked like you were running Flutter on top of a custom engine? I'm curious what that tech stack actually looks like. Did you go the custom embedder route and run Skia/Impeller on top of your (1/?)
documentation and little in the way of people actually doing it.
I'm personally a big fan of SDL3 (and their GPU abstraction layer), but I want more for UI than ImGui, and my tinkering with Flutter for entirely 2d stuff has been nice, but I find it's 3D capabilities (3/?)
I don't understand Matrices, Quaternions, row vs. column major, left handed vs. right handed coordinate systems, and how all of these systems interplay at all. If you give me an engine with a math/camera library already set up, everything is fine. But
I've been trying to create a basic arc-ball camera (for a week and a half now) and everything is just constantly, subtly wrong. And I can't tell if I've just failed to find the right combination of order for things, or if I'm inherently doomed to fail because
If I look in Blender and go "View, From Front", it has me looking down +Y, so presumably "Forward" is actually -Y. And then Z is up. And to move something visually to the right from this point you go in -X. But I can't contort my right hand into a shape that lets me point in
Bleh. Tried to re-up my @pixologic ZBrush subscription and now it's switched over to Maxon's licensing service. So I buy a month again, but ZBrush app insists I don't have a subscription activated. Finally get the inkling that maybe I need to upgrade to 2022.0.6 instead (1/?)
Why didn't the ZBrush installer install the Maxon app for me if it was a requirement for use? Why didn't it offer to uninstall the old version of zBrush since that's apparently no longer supported? So many questions.
