Like many others I loved Monument Valley, and especially the Escher-esque puzzles that it creates by taking perspective out of the equation.
That got me thinking about how to achieve that projection in Codea (ie objects do not recede with distance, and parallel lines stay parallel).
For the 3D experts on the forum this probably seems obvious, but I couldn't find any discussion of this on the forum so I thought I'd post.
In the 3D Lab demo that ships with Codea,
parameter.number("Angle",-360, 360, 45)
perspectiveline in the
drawfunction and replace it with this:
--perspective(FieldOfView, WIDTH/HEIGHT) ortho(-centre.x,centre.x,-centre.y,centre.y,-2000,2000) --orthogonal projection
This is what you get:
Now you just have to come up with the compelling level design, atmospheric graphic style, elliptic story-telling, immersive soundscapes, and Escher-esque puzzles, and you've got a certified iOS hit!
