Assume I have a model that is simply a cube. (It is more complicated than a cube, but for the purposes of this discussion, we will simplify.)
So when I am in Sketchup, the cube is Xmm by Xmm by Xmm, where X is an integer. I then export the a Collada file and subsequently load that into threejs.
Now if I look at the geometry bounding box, the values are floats, not integers.
So now assume I am putting cubes next to each other with a small space in between say 1 pixel. Because screens can't draw half pixels, sometimes I see one pixel and sometimes I see two, which causes a lack of uniformity.
I think I can resolve this satisfactorily if I can somehow get the imported model to have integer dimensions. I have full access to all parts of the model starting with Sketchup, so any point in the process is fair game.
Is it possible?
Thanks.
Clarification: My app will have two views. The view that this is concerned with is using an OrthographicCamera that is looking straight down on the pieces, so this is really a 2D view. For purposes of this question, after importing the model, it should look like a grid of squares with uniform spacing in between.
UPDATE: I would ask that you please not respond unless you can provide an actual answer. If I need help finding a way to accomplish something, I will post a new question. For this question, I am only interested in knowing if it is possible to align an imported Collada model to full pixels and if so how. At this point, this is mostly to serve my curiosity and increase my knowledge of what is and isn't possible. Thank you community for your kind help.
I have been informed by two co-workers that I tracked down that this is indeed impossible using normal means.
