3d Pixel Art (Pixelated) Games

Is there a simple example for 3d Pixelated rendering in Defold?

I have searched in various places but all I found is LowrezJam and Pixel Planet (youtube). Is there a more basic project that directly implements Pixelated rendering in 3d games?

I was very inspired by the project made with godot and I really wanted to make a game like that.

3D pixelation is just using low resolution textures and setting the nearest filter in the project settings, according to the link above.

But 3D in Defold is a wider topic. You can take a look at this or this thread.

Since you are specifically interested in pixel 3D, if this example is what are you looking for then take a look at the demo that comes with the trenchbroom extension.

Unfortunately, your picture didn’t load, so it’s not clear what type of 3D we are talking about.

Oh, 3d pixelation! Ignore my previous reply!

Yeah, Its my first time post on this forum, and i am not using english so, sorry if there is a “wrong translated word”.

I end up found “defold team explain” series on YouTube (uploaded 4 years ago) and that’s give me better understanding of render and shader work.

Then i render all models to render target, make a quad and get the texture from render target, finally i set the quad material and tweak the fragment program.

In the fragment program i add the glsl script for Pixelated Effect from Defragments Project that’s i found on github.

@britzl btw thanks, for quick respons!

It’s my 1 week of using defold and i already feel so accepted…

First week and already doing custom rendering with render targets, well done! :slight_smile:

Thanks, but i’m still struggle to make the projection of quad fit entire screen but still fixed aspect ratio when window resized…

Can you give me some example code, i use this for projecting the quad material

render.set_view(vmath.matrix4())
render.set_projection(vmath.matrix4_orthographic(-1,1,-1,1,-1,1))

Can you show the output effect?

In the example I did for simple lighting (or could be utilised for any postprocessing effect) I fill the screen with quad:

There I use a projection function (default is stretch, the same as explained in default render script: The render pipeline in Defold)

When you set projection always to:

render.set_projection(vmath.matrix4_orthographic(-1,1,-1,1,-1,1))

You won’t have it dynamic to e.g. window size, so take a look how projection matrices are calculated in default render script for different kind of projections :wink:
