Dependencies kept to a minimum. I basically vectorized the original code, added a few math types, cleaned things up and
|
||
|
|
made it clearer what the maths was doing.
|
||
|
|
|
||
|
|
I tried to make it more imgui-like, and removed all the excess stuff not needed here. This still needs work.
|
||
|
|
|
||
|
|
I also added triangle culling because ImGui doesn't support winding clip
|
||
|
|
|
||
|
|
The widget works by transforming the 3D object to screen space and clipping the triangles. This makes it work with any
|
||
|
|
imgui back end, without modifications to the renderers.
