-<h2>
-<u>Basic Objects</u></h2></center>
-
-<p><br>There are a number of objects which are the foundation for GEM.
-These objects are used in every patch and control the graphics and rendering.
-<p><a href="#gemwin">[gemwin]</a> - The window manager
-<br><a href="#gemhead">[gemhead]</a> - The start of a rendering chain
-<br><a href="#manips">manips</a> - Move an object in the window
-<br><a href="#geos">geos</a> - Render a shape
-<p><img SRC="tribar.gif" height=13 width=561>
-<h3>
-<a NAME="gemwin"></a>[gemwin]</h3>
-The graphics window is created and destroyed with the <i>[gemwin]</i> object.
-With the <i>[gemwin]</i> object, you can set the default size of the graphics
-window, create and destroy the graphics window, turn on and off rendering,
-etc. All basic GEM patches will have the following <i>[gemwin]</i>
-object with these messages:
-<center>
-<p><img SRC="gemwin.jpg" BORDER=1 height=128 width=78></center>
-The create and destroy messages will display and remove the graphics window.
-The 1 and 0 messages start and stop rendering.
-<p><img SRC="tribar.gif" height=13 width=561>
-<h3>
-<a NAME="gemhead"></a>[gemhead]</h3>
-The <i>[gemhead]</i> object is the start of every rendering chain.
-A simple patch, which is located in examples/gem_basic/gem1.redSquare.pd
-looks like:
-<center>
-<p><img SRC="redSquare.jpg" BORDER=1 height=138 width=91></center>
-
-<p>This patch will render a red square. The <i>[gemhead]</i> object
-signifies the start of rendering. The <i>[color]</i> object sets the color
-for all objects after it in the chain. The <i>[square]</i> object renders
-a square into the graphics window based on the current color, texturing,
-and transformations. In this case, there is no texturing and no transformation.
-<p>Every rendering chain <b>MUST</b> start with a [gemhead]. If you
-do not put a <i>[gemhead]</i> at the beginning of the chain, then nothing
-will be rendered for that part of the patch.
-<p><img SRC="tribar.gif" height=13 width=561>
-<h3>
-<a NAME="manips"></a>manips</h3>
-In the patch 01.basic/02.cube.pd, the <i>[translateXYZ]</i> object is
-introduced.
-<center>
-<p><img SRC="basicCube.jpg" BORDER=1 height=133 width=93></center>
-
-<p>The graphics are transformed and moved by the <i>manipulator</i> objects,
-or the manips. GEM has the following manips:
-<p><i>[color]</i> - set the color with a vector
-<br><i>[colorRGB]</i> - set the color with 3 discrete values
-<br><i>[rotate]</i> - rotate with an angle and vector
-<br><i>[rotateXYZ]</i> - rotate with 3 discrete values
-<br><i>[scale]</i> - scale with a vector
-<br><i>[scaleXYZ]</i> - scale with 3 discrete values
-<br><i>[translate]</i> - translate with a vector
-<br><i>[translateXYZ]</i> - translate with 3 discrete values
-<p>To understand the difference between the vector and discrete values
-version, realize that everything in is defined in 3 dimensions. These
-dimensions can be XYZ values, or RGB colors.
-<center>
-<p><img SRC="transXYZ.jpg" BORDER=1 height=92 width=201></center>
-
-<p>The two translate objects above will do exactly the same thing in a
-patch, but they provide two different ways to do it. <i>[translate]</i> accepts
-a scalar and vector. <i>[translateXYZ]</i> accepts three floats which
-specify a point in space. The manips will transform any object which
-appears after it in the rendering chain.

-<h3>
-<a NAME="geos"></a>geos</h3>
-Up above, we saw the <i>[square]</i> and <i>[cube]</i> objects. The other
-primary geos are:
-<p><i>[square]</i> - render a square
-<br><i>[circle]</i> - render a circle
-<br><i>[triangle]</i> - render a triangle
-<br><i>[cube]</i> - render a cube
-<br><i>[sphere]</i> - render a sphere
-<br><i>[cone]</i> - render a cone
-<p>The <i>[square]</i>, <i>[circle]</i>, <i>[cube]</i>, and <i>[triangle]</i> objects
-have a right-hand inlet to set the size of the shape. The default
-size is 1.
-<p>The <i>[cone]</i> and <i>[sphere]</i> objects are not perfectly smooth.
-They are actually composed of a number of polygons. In order to control
-the rendering better, the middle inlet is the size of the object, while
-the right-hand inlet is the number of slices to define the shape.
-Take a look at the patch gem_basic/gem3.sphere.pd to see how the number
-of slices can change the look of a sphere. Don't worry about the
-<i><a href="Lighting.html#world_light">[world_light]</a></i>
-object, it is just there to make it easier to see the difference in the
-number of slices. Make sure to click the 'lighting 0' message before
-closing the patch (if you don't, then other patches will probably be completely
-black until you quit and restart pd/GEM).
-<p>Your graphics window should look like this for 5 and 15 slices:
-<center>
-<p><img SRC="sphere5.jpg" BORDER=0 height=150 width=150><img SRC="sphere15.jpg" height=150 width=150></center>
-Obviously, the more slices that you use, the better the sphere looks.
-However, each slice adds more polygons, which can slow down your frame
-rate. In computer graphics, there is always a trade off between resolution
-and speed.
