Cache 2D shapes as bitmaps?

UnknownUser

Hi! Maybe I'm not looking for the right keywords … is there any way to store shapes (like Polygon2D or anything I draw inside _draw as bitmaps/rasterized images? I'm guessing and am already seeing that when I get to a larger amount of drawn shapes, there is a significant performance hit, even with not very complex shapes. Bitmaps should be better performance-wise. But can I convert my drawn shapes somehow?

You could maybe draw into a Viewport node and then get the ViewportTexture. Then you could convert the ViewportTexture to an image or tell the Viewport not to update anymore, which should leave the texture showing all of the drawn shapes. I think that may work, though I'm not sure how much it would effect performance.

Indeed viewports are essentially glorified rendertargets, that is one way to use them.

Thanks @TwistedTwigleg and @Megalomaniak . I shall try this when I get around to Godot next. My main concern is performance, so we'll see if there are any benefits. ?
