- How to use Clay
- ~~~~~~~~~~~~~~~
-
- A rudimentary knowledge of point and click systems and a mind for 3d
- is all I ask:
-
- When the program fades up, you will be presented with a screen of
- 4 windows, abd an array of tools around the edge.
-
- The panel to the top-left contains all the drawing functions you need,
- the name of the current function is also displayed in the centre-top
- of the screen. You can also select mode using the 'Edit' menu.
-
- The draing mode is defaulted to select which may be daft because there
- is nothing yet too select.
-
- Right, folks. Lets draw a square!
- Straddle that mouse and click on the icon to the right of the little arrow.
- You are now in 'Square' mode. Pick one of the orthographic windows, ie, not
- the 3d one. Using the left mouse button click and drag a square, release when
- finished and there you have it, a square.
-
- The 3d cursor
- ~~~~~~~~~~~~~
-
- Things get a bit more complex when you draw cube or a cylinder but not a lot.
- There is, in the centre of each window, a cursor. Try holding the right mouse
- button down and draging in any of the editing windows. The cursor follows the
- mouse but also moves in one plane in the other two windows.
- This is the 3d cursor and it will allow you to give your drawings depth.
- Now, click on the 'Cube' icon. Draw a square as before but now go to another
- window and move the cursor about. Draw a new square in the window you drew
- the first one (you can draw in any of them but it wouldn't look much like a
- cube). Get the picture? Now if you had clicked both buttons together, you
- would have automaticly made a perfectly extruded object. The cylinder
- function works in the same way. The sphere, cone, dot and grid functions
- all operate on similar principles.
-
- Selecting and it's generic goodness to society
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Had a good fiddle? I do hope so. Right, now we can get onto the cooler stuff.
- Draw an object of your choice. Once you've done that, go the the 'select' tool,
- and well, select it. A box should appear in the top right, giving you 3
- options,of which on the top two do anything. Try clicking on a node, in any
- window, and draging it. It moved, right? Wow. That's quite useful, really
- but it's not as much fun as it is when you miss a node and you get this red
- box. Try that and drag said box over a number of points. Depending on the
- 'select mode' you should either get a plane box or one with nobes on. I'm
- sure you've seen bounding boxes like this before and they do what you'd
- expect. Try moving it about and stretching it and then rotating it using
- the other function.
- You can do other things with selected points, such as fliping them in X,Y
- and Z, deleting them and using them to create new objects.
- You will be shortly be able to extrude object using this system but for now
- all you can do is make a sweeped rotational form. To do this, draw a list of
- points around one side of an axis, select those points and then go to the
- 'rotate' drawing mode. clicking in an axis will now rotate those points
- about the centre of that axis. You can make some good objects using this
- function.
-
- Text
- ~~~~
- You need a bgi stroked font loaded. When you click on this function, a
- text prompt dialog appears. Enter a string in here and drag a box in any
- of the windows. A text string will appear in the current font style but
- will not yet shrink or grow to the size of the box you dragged. Later....
-
- Other little functions
- ~~~~~~~~~~~~~~~~~~~~~~
- Selecting a colour in the palette box will determine the colour value of the
- polygons and, as of yet, nothing else. Eventually this will be replaced by
- a 'texture' dialog box that will allow texture maps, bunp maps, shinyness
- and transparency attributes, a global colour term and anything else I can
- think of.
- Double clicking on the palette box will create a colour editing dialog,
- good for changing the look of the desktop, mostly.
-
- 'Mesh'
- ~~~~~~
- This is a multi-purpose little box of fun. The value in it dictates how
- detailed your spheres, circles, rotated forms, grids and cylinders are.
- It can range from 3 to 30 and is quite useful, really.

- Have fun.
