Hi Sascha. I saw some requests about exporting formats, a big number of comments about classical triangulation export ones. But I was thinking... what about render image formats ? As I understand SDF Modeler is more about shaders isn't it ? As 3d in this case involves depth in some case I suppose, could  rendered image keep some information in a kind of "pass" maybe in a format that keeps it like HDR or more open one like EXR. I tried some apps using depth in relation with transforming 2d to 3d or mixing depths of 2 images in a 3d render even beeing polygonised afterwards... Are you planning to develop to render separeted "passes" in the future ? Or will you take another direction ? 

Thanks for your good (excellent should I say) job. Have a nice day.

Yours, Dan

Hi Dan,

A lot of people ask about some kind of “shader export” they could plug into Shadertoy or similar. The thing is, SDF Modeler doesn’t just brute-force raymarch — it uses a more sophisticated setup under the hood. That’s why it runs fast even with lots of shapes.

So simply exporting “passes” or a GLSL shader wouldn’t really reproduce what the renderer does here, and in practice would likely be far too slow.

Cheers,
Sascha

So, you mean?... Please excuse me for my ignorance in that matter---The viewport should be temporarily less reactive? Or exporting a 2d  black and white or grayscale render of an image in HDR format instead of png could take too long to render ? For sure this seems complex more than I can imagine. For instance I just know that in Blender the depth can be rendered in the viewport in eevee realtime using opengl or vulkan, but it's another story. This radically seems not to be based on the same basis, and even if im not a developper the idea was simply interesting in an artistic point of view .

Please let me know eventually what you think if you wish. However thanks for your explanations and for your time. Good evening.👍

Ah, got it — thanks for clarifying! I was thinking in a different direction. That's not something SDF Modeler is really focusing on right now, since the main goal is interactive modeling and mesh export. But I do see the artistic use case you have in mind, and it could be interesting to revisit later once the core feature set is more solid.

Cheers,
Sascha

Hey, promising ! But challenging probably 😉

Thanks Sascha.
