Right, so here we go, a proper start this time.
First off some basics on perspective in case you didn't watch the videos/read the books.
Perspective is a thing that makes stuff look proper and right. Something that makes your drawings feel like a 3d image, instead of something flat and lifeless on a piece of paper or flayed skin.
The gist of it is that every image has a horizon line, or the eye line, it sits at the eye level, regardless of wether or not it is actually shown in the image. And it is on this horizon line that all vanishing points lie (usually, we'll talk exceptions later). Now the vanishing point is this eldricht black hole that sucks and distorts all the lines towards it. If a line is not parallel with the horizon line, then it will be heading to a vanishing point along with any line parallel to it, this can be located within the image itslef or somewhere off to the side.
You can have a number of vanishing points, depending on your needs and how realistic you want your image to be. Ideally, two point perspective (that is, two vanishing points) is the ideal mix between realistic and effort. Three point being the most realistic looking, but at the same time the most requiring to pull off. While one point is somewhat limited but at the same time rather easy and quick to pull off.
Now, this doesn't mean that there's a right or wrong number of VP's you can use, it all depends on what you want to depict, how, and how much effort you want to put in.
Now, these are rough basics and hard to convey without some imagery, so we'll lazily leave that out because I have 40 Mb's of bandwidth left and finding and uploading the needed stuff would eat it up rather quickly.
So we'll merrily and blindly jump into it. If you have any questions feel free to ask, this is barebones because I don't want a wall of text with ALL the information, this is purely to get you going. Because it would be too easy to serve you everything (and far too much work for me
) and that wouldn't be fun now, would it.
Here are the five tasks to complete by next Thursday morning:
1. Draw an object in one point perspective
2. Draw an object in two point perspective
3. Drawn an object in three point perspective
4. Find a work of art (photograh, painting, anything really) that you like (and I suggest something with manmade objects because those are the easiest to analyze) and figure out how its perspective is constructed, ideally replicating it with rough geometric shapes
5. Construct your own full scene with a perspective of your choice
These are meant to get you to figure out how perspectives work, conduct a study of how they apply to real world stuff and then use them to make something of your own.
Next week we'll go into the murkier parts of perspective, curves, circles, foreshortening and other vicious things.
