- kjksf 9y agoThe way XRay render text is more compositing than rendering. They will render text to a bitmap using HTML canvas and then use that as a texture for GPU. GPU will be compositing those bitmaps, it won't actually be rendering text.
- codedokode 9y agoIs it really so? Can OpenGL update only a small part of a framebuffer (for example, when a single letter is typed) or will it rerender the whole text?
- zaarn 9y agoDepends on how you render. I've written a OpenGL engine for a university course that use partial frame updates to reduce the number of redraws per frame. IIRC the partial rerender variant was about 3 times faster than the full render.
- bitcoinboi9 9y agoIf done in a smart way, of course you can. Similar thing with canvas. If letter/word spacing depends on that character, then you'd probably need to rerender more stuff.
