Let's
take a look at Contour Line drawing. Basically it is
a way of using a line to fill in a shape or space. By
following the shape or contour of the object being drawn
you will define its shape. It is important however to
see the shape as it is. For example lets take a ball
and an apple. When rendering a ball you would want to
create the illusion of roundness as in the figure to
the left. Something like a planet or beach ball.
If you were to render an apple you
would want to use a line more like this one to the right.
It illustrates the line more common seen in an apple.
Although the shape is rendered round you can still see
an apple in it. Maybe an onion or a pear, how many objects
can you think of that might be rendered using these
two techniques?
Now
for scribbling or sometimes called scumble drawing.
Basically it is a way of using chaotic continuos line
to fill in a line drawing or to render a drawing from
a model. In this next example it is easy to see why
I call it controlled chaos drawing. It is a real easy
way to fill in an area quickly and create an interesting
texture in your drawing. This illustration was rendered
using one continuous line. Think of a tennis ball of
twine or string.
This
illustration was rendered with wavy lines from left
to right. Noticing that the lines are closer together
at the bottom and farther apart at the top. This could
be a Styrofoam ball or an orange.
On
the left you will see an example of crosshatching. Crosshatching
creates great looking textures and suggests a more lineal
definition in the drawing. It looks flat compared to
the next example of crosshatching using curved lines.
This would be good to use to render cloth or a wall.
Using the curved line while using
this technique creates the illusion of mass and therefor
roundness. Go ahead and draw all of the examples illustrated
on this page. See how may objects you can think of to
render using these techniques. It just depends on your
particular application and what you may feel more comfortable
with. You can even mix and match the different styles
to create even more textures.
