I have a question about the horizontal cross section. Does that mean only top down is allowed as opposed to other views: isometric, oblique, etc...?

I'm in
Its my typical environment (restrictions - not caves ;)
And topic is worth effort

@Anonzs, so long as you can see into the cross section the angle/perspective should not matter. That's the challenge ;)

WIP. I describe it as a "crystal cave dug by the ancients" with a couple of torches placed on the walls, a thing with a chinese dragon head statue with water coming from the eyes, and a passageway that leads to another hall, but I dunno for sure if that's enough to make it count as a cross-section image of an underground structure... Does this qualify, or do I need to add/remove/change something to make it qualify?

Can anyone show an example of a 'cross-section'?

The XCOM: Enemy Unknown base screen is a good example.

That explains nothing.. |:
If I got anything from wiki, is it something along the lines of having one vector interject with another / one corridor interconnect with another / a room?

EDIT: Okay, wiki went apesh*t on me. This has nothing to do with Orthographic Projection, right?

Whoops, sorry about that. I put a link there to show a screenshot, but it didn't link properly.

Ant farms are another good example. -

*sob sob* I still don't get it. And the dictionary is not helping with an actual mental image. Is this one really that obvious, but I am just missing it?

it's really simpel. I might start over and make a "painted" image tho...

When you slice an apple or orange in half, you get a cross section of them.

Basically, think of it as more-or-less a side view (although it doesn't have to be strictly side view) of the inside of a volumetric object (or scene/structure, in this case).

A typical cross-section is as Dr D described, "slicing" through an object. Here are two common methods for depicting cross sections:

Orthographic Projection (Flat)


A cross section is a valuable tool used to see interiors and structure, ratios, relation between spaces; essentially anything not immediately visible or apparent from the outside.

I don't think I'll have time to finish this, but I needed to vent some stress out with doing random pixel art so I just picked this week's theme as the stress reliever.

Anyway, cliff mansion with a secret underground lab (think batcave) is what I was going for.

Ohhh, please finish it (of course, if you can't then you can't, but still...)! This is a great start! You have some fantastic sky colours as a start!

Looking great! Really loving those bricks.

Nice explanation Archerhar!

hmmm... I know I want mountains in the back ground. But the palette needs a face lift. I might just steal a 16 palette and give cred. and Yes I do do do need to work on my colors.

I've just got one word for you...


or is that two?

So it is related to Orthographic projection. Alright, very well.

This was done both for this weekly challenge and as a concept for a very late job application (which of course I botched because of the late application).

I'm planning to use the large version as a zoomed in view, inspired by what Nevercreature did with his isometric game mockup :)

Small update. changed the bottom bricks, im not sure how they should look :/. im going to think about some stuff to go in the dirt, to add some detail.

also, should I keep the updates on one post?

hmm hows this im not sure wether the lower half of the well makes sense tho?

Posted By: felchqueen
Date Posted: 21 May 2014 at 10:43am
@Pixel Chicken, would a well have a bottom? Wouldn't there be an aquifer there, perhaps you could pixel how the water percolates through the ground with all the channels and underground caves it creates?

Hey guys !! long time no pixelling, I sometimes doodle a few things but no serious business for very long. I must admit it's a pleasure to get back at it :)

I love making tilesets and this challenge is a great occasion to follow MrmoTarius' teaching : "If in doubt, use tilesets!"

A lot of tiles are just mirrors/placeholders, I still have to make a bunch of them and I'll propably assemble them up at last minute, touch things up. I might be short on time though

Any C+C welcome as always

Mmmm, you get great depth with your tiles. I really love them! I believe I remember an old tileset you made that was fairly abstract on wotp; that one will always stick with me as really awesome!

Posted By: FrostPumpkin

Thanks Mr.Fahrenheit ! Very inspired bit that old tileset of course, I wished I could use it haha :) Some of the metal tiles are nearly the same

Thank you Gecimen! Sadly I couldn't finish the entry I started working on, hopefully I can continue working on it at a later date.
