P3D renders edges blurryly

Processing Coding Questions

P2D and the default renderer give me the same crisp not blurry results as each other. But both suffer severe frame loss when pipes are displayed on screen.

P3D, (which I was at the time calling as fullscreen(OPENGL)) never drops a frame below 60 even on Android
Because of this I have been using P3D for a 2D sketch, not changing anything other than the declaration of the renderer used.

A side effect of using P3D, is that it makes the edges of lines blurry.

What I am trying to do is get rid of the blur introduced by P3D.

with This is the rendering with P3D enabled
without This is the rendering with the default renderer

The Screenshots dull the effect somehow, it’s much worse in real life
(tested on multiple monitors)

Could you post screenshots of the differences between the two for comparison?

I am recreating Flappy Bird, so the lines are supposed to be very hard.
While I know openGL is for 3D applications, it handles drawing images so much better than P2D it doubles my framerate when many images are visible.

Possibly try initializing the sketch with

hint(DISABLE_TEXTURE_MIPMAPS);
 ((PGraphicsOpenGL)g).textureSampling(2);

Alternatively, you might try increasing/decreasing the size of whatever surface you’re rendering on by some small amount.

What does that mean? What renderer are you using? P2D is not the default, it’s a 2D OpenGL renderer. P3D is the 3D OpenGL renderer.

err, did you try noSmooth(); ?

Yes, I forgot to write that down

Did you try FX2D ?

Interesting, I just did and it gives me the same frames as OPENGL, with the same issue with blurry lines.

I will look into the provided solution in your link.

SOLUTION:
a. if you are just switching to OPENGL/P3D for FPS, use this solution from rufsketch 1 in your main to get back your hard lines

b. if you need to have edges not blurry in FX2D,

Haha. No big deal. At least his additional solution also includes info for FX2D.
