<h1>Texture Coordinates Window</h1>
<p>
The <b>Texture Coordinates Window</b> is used to change how a texture is
applied to the faces of the model. It applies each vertex of a face
to a point on a texture. The texture is then stretched between each
vertex on the face to create the final texture appearance on the model.
To change the texture coordinates, select faces you wish to modify
and select <b>Edit Texture Coordinates</b> in the
<a href="olh_mainwin.html">Main Window</a>'s <b>Groups</b> menu.
</p>
<p>
The <b>Texture Coordinates Window</b> contains four major elements:
</p>
<ul>
<li> <b>Texture Frame</b> - Shows the texture image with vertices
and faces drawn over it.</li>
<li> <b>Mouse Tool Buttons</b> - Determine what happens when you use
the mouse on the <b>Texture Frame</b>.</li>
<li> <b>Scale Options Frame</b> - Gives some control over how the
scaling operation works.</li>
<li> <b>Map Scheme Buttons</b> - Change the initial coordinate mapping
scheme for the selected faces.</li>
</ul>
<p>
The <b>Texture Frame</b> viewport shows the texture used by the selected
faces. Faces and vertices are drawn over the texture to show where each
face's vertices are applied to the texture. Vertices can be selected,
unselected and moved using the left and right mouse buttons. The exact
operation performed by the mouse depends on which <b>Mouse Tool</b> is
selected.
</p>
<p>
The <b>Texture Frame</b> is very similar to the model viewports.
You can pan around the <b>Texture Frame</b> by using the arrow buttons inside
the frame window, or by middle-click dragging. You can zoom in or out by using the
<b>Zoom Buttons</b> or by using the mouse scroll wheel.
</p>
<p>
The <b>Rotate CCW</b> and <b>Rotate CW</b> buttons rotate the selected
texture coordinate vertices 90 degrees counter-clockwise and clockwise.
</p>
<p>
The <b>V Flip</b> and <b>H Flip</b> buttons will perform a vertical or
horizontal flip on the selected texture coordinate vertices.
</p>
<p>
The <b>Mouse Tool</b> buttons determine what the mouse buttons do when
used in the <b>Texture Frame</b>. Most tools operate in a similar fashion
as the tools in the view window (an exception is that you may
only select vertices).
</p>
<ul>
<li>The <b>Select</b> button allows you
to select vertices with the left mouse button and unselect vertices with
the right mouse button. You can hold the shift key to make your selection
cumulative.</li>
<li>The <b>Move</b> button allows you
to move selected vertices.</li>
<li>The <b>Rotate</b> button allows you
to rotate selected vertices.</li>
<li>The <b>Scale</b> button allows you
to scale the distance between selected vertices. Using the
<b>Scale Options</b> frame you can control whether you scale
from the center of the selected vertices or the far corner
and whether or not the 2D aspect ratio of the selection is
preserved during the scaling.</li>
</ul>
<p>
The <b>Map Scheme</b> buttons are used to set the initial coordinates for
the faces. The <b>Triangle</b> mapping uses the same coordinates for all
three vertices of each face. The <b>Quad</b> mapping uses three coordinates
from two triangles for alternating faces. The <b>Group</b> mapping projects
the selected faces from a specified direction onto the texture image. Each
vertex has its own coordinate and may be moved independently.
</p>
<p>
When you click on the <b>Group</b> radio button you will be prompted to chose
one of six directions. Misfit will take the selected faces as they appear
in the orthographic view of your chosing, scale them to the size of the
texture image, and project them onto the texture image.
</p>
<p>
<a href="olh_projectiondetails.html">Texture Projections</a> are a more
powerful alternative to the group mapping scheme.
</p>
<p>
The <b>Reset Coordinates</b> button is used to reapply the current map scheme
to the texture coordinates. If you click this button while using the <b>Group</b>
mapping scheme you will be asked to pick a direction again.
</p>
<p>
The next time you open the <b>Texture Coordinates Window</b> with the
same faces selected, it will show the vertex coordinates that you set
previously.
</p>
<p>
Press <b>Close</b> to close the Window.
