Creating a perspective drawing from a floor plan

[demotlj]

I've been playing with trying to create interiors in perspective starting from a floor plan. If I am understanding correctly, you begin by creating a perspective grid of the floor and walls in which the grid is made up of equally measured cubes (1 foot per side or 2 feet per side, for example.) You can then choose your point of view and place the furniture, doors, etc, in that room by knowing their measurements and just counting the grid cubes for their space on the floor and their elevation.

I notice that many youtube videos, however, talk about "station points" and do a lot more geometry than I am doing when creating perspective elevations from a floor plan. Am I missing some fundamental steps in the process?

@davidhohn Any thoughts?

@demotlj What you've described is very much the way I do it.

Station points are simply where the viewer (or in this case artist) is standing in relation to the room being drawn. Station point is both the location on the ground and the height of the viewer.

You can absolutely use some (not too complicated) math to determine all of this. Including cone of vision based on a camera focal length or degree of field of view.

But I find this to be overwhelming and prohibitively complicated when starting out. So you'll see that I didn't address it in the SVS perspective classes I created.

That said, once you have a handle on perspective, and you want to introduce that level of precision to your drawings I would certainly encourage mastering this.

I can see an architect, product designer, or background artist for animation really needing to understand this, because other people down the pipeline will be using the drawings to further develop the project.

@davidhohn Thanks. I was thinking that it might be useful because photo reference never shows more than one point of view. If I could find floor plans I like and build/modify interiors from that then I could choose my own point of view.

Mostly, I just like learning how to do things even if I never use it

Absolutely do this! That is the goal of the SVS perspective classes. Definitely a skill worth developing.

@davidhohn I just finished your Basic and am going to start the advanced. Great stuff and you are a great teacher. Thanks.
