- QuickDraw 3D - TextureEyes For Windows
-
- TextureEyes is a QuickDraw 3D application for illustrating how pictures can be
- applied to 3D objects. You can select from a simple set of 3D objects in the
- palette or drag more complex 3DMF files into the window and manipulate them to
- view them from any position.
-
- This application also demonstrates what's possible with the standard toolbox
- routines from the QuickDraw 3D and QuickTime system extensions.
-
- * System Requirements *
- This application is designed for Windows 95 and NT with QuickDraw 3D.
-
- * Exploring TextureEyes *
- To begin select one of the geometry models in the Geometry Palette or open a
- 3D model file in 3DMF format with the Open command to view more complex 3D
- models. The built-in geometries in the Geometry Palette are trigrid, box and
- conic and quadric geometries. The conic and quadric geometries (torus, ellipsoid,
- cone, and cylinder) can be substituted with similar looking representations based
- on trigrid geometries. See the end of this document for more information on this.
-
- * 3DMF File Drag and Drop *
- A simple way to view other 3D models is by dragging 3DMF files directly from the
- Finder into the application's window. The button in the Geometry Palette with
- the 3DMF document icon highlights to show the model was imported. Note that if
- you wish to apply textures to the model the imported model must have UV parameter
- information.
-
- * Texture Menu *
- The Texture menu lets you select the type of texture applied or mapped onto objects.
-
- You can apply different pictures onto an object's surface by choosing the Picture
- item under the Texture menu. TextureEyes comes with a built-in set of picture
- textures. Some of the pictures produce very realistic looking results, especially
- on more complex models.
-
- The Geometry and Face menu options determine whether a texture is mapped across
- the entire geometry or on the smaller facets of the geometry's surface. Note the
- Geometry selection has no effect with the built-in box and skewed box geometries.
- Also, for many of the other built-in geometries the QD3D 1.5 Conics item should
- be checked. Conics and quadrics are only available with versions of QuickDraw 3D
- 1.5.
-
- * View Menu *
- The View menu has options for changing the scene's overall appearance and
- controls for changing the geometry and window background colors.
-
- Choosing the Subdivision item brings up a dialog to let you to choose between
- Constant, World Space, Screen Space subdivision methods. The U and V fields
- control the number of subdivisions in each direction for the subdivision methods.
- You can clearly see how subdivision works by choosing the Wireframe renderer.
-
- The Background Color option changes the window's background color.
-
- The Auto Rotation menu item lets you stop and start the model from spinning
- continuously if is has been set in motion after clicking and dragging inside
- the window. Another way to stop the model from rotating is to click once in
- the window without moving the mouse.
-
- * Settings Menu *
- The Settings menu has general options for showing and hiding the main Geometry
- and Paint Palettes.
-
- The main Geometry and Paint Palettes can be shown and hidden from the Settings menu.
- The first eleven buttons are the geometry buttons plus the last button which represents
- any models imported into TextureEyes. The last four buttons at the top of Geometry
- Palette control how the object is manipulated when the cursor is clicked and dragged
- inside the window. These object tools are the Rotation, Scale, Move, Zoom, and
- Home buttons.
-
- The Paint Palette and Change Brush menu items are only available with QuickDraw 3D
- version 1.5 or later. The Paint Palette provides a basic set of paint colors.
- Below these are various brush shapes with an eyedropper and eraser. The eyedropper
- picks up the color of the texture beneath the brush and substitues it for the color
- in last color button. This is used to pick up a specific color in a texture and
- blend it across neighboring areas in the texture. Using the eraser restores texture
- with the original pixel colors. Painting currently does not work on models imported
- into TextureEyes that already have textures.
-
- If the Change Brush item is active this presents a dialog for selecting how the paint
- is applied: Solid, Feathered, and Blended. Choosing solid applies the paint for the
- entire the shape of the brush. Feather softens the application of the paint near the
- edges of the brush's shape. Blend mixes the paint's color with the colors of the
- texture as it's applied. You can also have a visible Line or Pencil at the point
- where the paint meets the surface of the geometry. The Pixel Spacing and Minimum
- Spacing control the rate at which the paint is applied.
-
- When the Paint Palette is visible 3 modifier keys can be used to help you with your
- painting. These have an effect when the key is held down and the mouse is pressed
- within the window. The control key temporarily switches to the current tool for
- manipulating the object.
