Hello gizmo199,

I hope you're well ! :)

Thank you very much for your framework Fauxton 3D, I love it very much !

I have created a shadow system for dynamic and static "3D "objects (in buffers) for my game (also for 2d sprites). The shadows are aligned with the x, y and z axes of the sun in the ‘WorldEnvironment’ object.

Unfortunately, I wouldn’t know how to integrate it into your framework for the community. I know you no longer have time to work on the framework, but if you ever feel like adding shadows to it, don’t hesitate to ask me for the code :). The code is very little.

Below is a preview of the shadow system using only static elements with the sun position updated every 0.5 scd:

Nice! Looks great! I would probably recommend using a separate camera, submitting all of the fauxton models raw to that camera & a surface (for shadow mapping) and then updating the fauxton shader to take in the shadow map. I highly recommend this video if you want to learn more about shadow mapping in GM!

Great work though! Looks awesome!

Thank you for the advise, I will watch the video, I hope it's not too hard 😆

Actually :

- for static object I draw shadow on a surface and I create a sprite based on the surface. So I have to calculate one time shadow so it is very fast. I calculate shadow just if the position of the sun change

- but for dynamique object, I draw shadow on a surface for each step, and it's not very fast. I think it can be better to calculate the shadow only if the state of the object change
