Spiral stone staircase – part 1 « phantascene

Among the first unpredicted hurdles I stumbled upon for making my castle, and just what lead me to go back to Phantascene to supply information to other people when i sort out my efforts, was a problem with steps to make a spiral staircase for any tower.

Stairs their very own listing of issues with regards to 3D and spiral stairs I’ve discovered have been in another class that belongs to them past other kinds of stairs.

The very first concern is scale. How can you build stairs which are correctly scaled for any gaming or any other 3D rendering? In 3D Game Environments, Luke Ahearn informs us that scale is really a difficult factor to determine when it comes to a game title world. An individual who looks correctly scaled for their surroundings may be 8 ft tall, as the door they’re walking through might be 15 ft tall. The easiest method to measure scale would be to determine what looks proper inside your game world and uncover sizes for other objects according to that fundamental measurement.

In my purposes I want a spiral staircase that may easily fit in a tower to permit the gamer to achieve with a home bottom floor towards the second floor. It ought to begin just right from the doors and spiral around for just one level in a circular tower which was built only for the staircase to obtain the player in the bottom floor towards the second floor after that time to the third floor when they desire.

Looking for a great visualization of the items I want, Used to do searching for medieval spiral staircases and located two excellent searching examples which are not far from that I wish to achieve.


These staircases are great examples, however i believe that the tread isn’t quite wide enough or use within a game title atmosphere. There’s also something… odd concerning the steps around the lower left from the sepia-tone image. All of those other image is excellent, however, and the majority like what I’d like my staircase to appear like when it’s finished.

The castle I’ll be being employed as a beginning is made of Harlech Castle in north Wales.  My sources for layouts and pictures would be the preceding page in addition to RPG Booster – Harlech Castle and also the layouts available at Harlech Castle’s page on HogwartsCampus.com.

I won’t be sticking strictly towards the floor design or even the beauty from the castle, however i deeply love the look of the castle and will also be utilizing it like a base for that seaside castle I will build in Blender.

First, the steps. Should you consider the plans for Harlech Castle, you can observe it has four small stairwell towers. All of these are roughly exactly the same size, therefore it works to construct one stairwell and replicate it to another three points on the ground plan. First, however, the steps are necessary.

In Blender I begin with a fundamental block that we then extend in to the general form of among the steps. The narrower and taller the step the greater the steps will rise from the first one to second floor, but we have to take care not to allow it to be too steep in order to lift the steps a lot the animations look weird once the player ascends and descends the staircase.

This is when we return to the tricky scale calculations. I made the decision to begin with the staircase because after i obtain that designed to look right, all of those other castle should virtually scale itself round the stairs.

For individuals who wish to get really technical around the proportions of a spiral staircase, Spiralstaircase.com has some measurements for which the conventional codes are. The key measurements are: roughly 6.5 ft minimum from floor to bottom of stairs above your mind, 9.5″ rise on steps, and seven.5″ wide measured 12″ out of the outer wall from the spiral. The recommended minimum stair width is 26″ from center column to outer wall.

Regrettably, as nice as understanding that is, as Mr. Ahearn stated, individuals measurements are not big enough for game space. It might look very cramped and also the camera would have a problem panning around for that player to really see anything more. And anybody which has ever performed a relevant video game knows that we’re all slaves towards the camera perspective inside them.

How to proceed then? We create a step after which use our very best guesstimates on precisely how to put together that right into a flight of spiral stairs that appears good on the game screen.

Because the steps will all look pretty very similar, and also the bottom is going to be simply an even surface, I’ll start my staircase with the style of just one step.
