MODELER __________________ ! ! ! ._/ ! ! ! ! ! !_. &SHADER - E X A M P L E 3 - THE DANCING GOBLET A few words before we begin with this 'classic' tutorial: the steps outlined below have been chosen to demonstrate a wide number of features. There are certainly a number of shortcuts to get to the same results. This however, was not our objective. 1. Start InShape and select NEW from the FILE menu to clear the memory. Enter the object editor, then select TEMPL. to enter the template editor. 2. Set the SCALE to 2 cm and center the yellow box over the cross hairs. Press the left mouse button. 3. Select the GRID option (1st icon, 2nd row). Activate SNAP to GRID (2nd icon, 2nd row) as well. 4. Move the cursor into the work area. Position the mouse so that the X/Y position above the work area displays: Mouse X: 0.00 Y: -400.00. Click on the left mouse button. 5. Now move the cursor to these locations, again pressing the left mouse button at each position: X Y 260 -400 260 -380 20 -360 20 120 6. Select the ELLIPSE (icon with the compass & circle) tool and enter these values: X - Radius : 280 Y - Radius : 260 Angle begin: 0 Angle end: 90 Rotation : 90 Points : 8 , then click on [ OK ] 7. Press the right mouse button and draw a yellow rubber-band box around these newly generated points. Release the mouse button and select INSIDE. There should now be eight yellow squares (active points) on your screen. 8. Click on the MODE icon (2nd icon in the 1st row, the one that currently shows the single filled circle [point mode]). Select the MOVE X/Y icon. 9. Position your cursor over the leftmost active (yellow) point of the selected points curve. Press the left mouse button and move the mouse a bit to the right and upwards until the readout above the working area says: Trnsl. X: 60 Y: 400. Release the mouse button. Deselect all active points by clicking on the DESELECT icon (1st icon, 4th row, the one with the three hollow circles). 10.Position your cursor at X: 40 Y:100. Press the right mouse button, open the rubber-band box and move the mouse towards the upper right hand corner of the display until all but the topmost point are within the yellow bounding box. Release the mouse button and select SMOOTH. 11.Open the ELLIPSE dialog and change the X - Radius to 260. Exit via [ OK ]. Again, select all newly generated points, place your cursor over the leftmost point and move all eight points until the readout displays: Trnsl. X: 40 Y:400. 12.Press and hold ALT and click on the leftmost and topmost of the yellow points, thus deactivating them. Draw a rubberbox around the remaining yellow points and select SMOOTH. Deselect all points with the DESELECT icon. Press and hold ALT and click on the point at X: 40 Y: 140. Now, drag this point so that it now lies at X: 0 Y: 140. 13.Click on the INFO icon. You should now have a total of 21 points. 14.Move the cursor over to the working area and press the right mouse button. A pop-up menu will appear. Select the icon that shows the single line. 15.Place your cursor over the point at X: 0 Y: -400. Click on the left mouse button. Move over to X: 260 Y: -400 and again, click on the left mouse button. You now connected the first two points. Proceed connecting the points at X: 260 Y:-380, X: 20 Y: -360 and X: 20 Y: 120. Next, keep connecting all the points on the outer curve of the goblet until you reach the point at X: 320 Y: 400. Now, connect all the points on the inside curve until you connected the last of the smooth points (circles) with the point at X: 0 Y: 140. 16.Select SAVE from the FILE menu and save your new template. 17.Next, select SPIN from the EXECUTE menu and click on [ OK ]. 18.In the SURFACE dialog, click on the [LOAD] button. Now search for the \SURFACES\MINERAL\ path and load the DIAMOND.ISF file. Click on [ OK ] Back in the surface dialog, (after activating the selection the selection in the newer versions using the [>] button), click on the REFRACTION box and select >CRYSTAL<. Click on [ OK ]. 19.The program returns to the object editor. Press F2, then place the mouse cursor at the lower border of the screen. Press the left mouse button and move your mouse upwards to encircle the object as closely as possible. Release the mouse button and the screen will be redrawn showing the object in full size. 20.Select the OBJECTS icon (1st icon, 2nd row), and rename the first object to 'Goblet'. Press OK and exit the dialog. Select the LAYERS icon (2nd icon, 2nd row) and enable the EDIT and DISPLAY boxes of the first layer. 21.Select the ACTIVATE ALL POINTS icon (1st icon, 4th row) to enable all points. Click on the TRANSLATE icon (2nd icon, 5th row) and enter the following values: X: 0 Y: 445 Z: 0, click on [ OK ]. This will move the object along the Y - axis. 22.Select ROTATE icon (2nd icon, 6th row) and enter these values: Angle X: 0 Angle Y: 0 Angle Z: -10, then click on [OK]. This will tilt the object 10 degrees to the left. Choose ALL from the DISPLAY menu to center the object on the screen. 23.Save your object (SAVE AS... in the FILE menu). Go to the scene editor. Click on the CAMERA icon and enter these values: Position X: 35 Y: 500 Z: -1390 Point of view X: -65 Y: 450 Z: 0 Up vector X: 0 Y: 1 Z: 0 Horizontal angle: 70, and click on [ OK ]. 24.Click inside the working area in the scene editor. The hierarchy window will be displayed. Place the mouse over the MAIN ROOT box and press the left mouse button. Select ADD. Now, use the right mouse button and click on the MAIN ROOT box again. A new dialog will appear. Under Light, select POINT and enter these values: X: 50 Y: 1600 Z: -50 ... Radius: 0.3 25.Click on the [>] button. Enter 'Goblet' in the NAME box. Select SPOT as the new light type, then enter these values: X: 20 Y: 1800 Z: -10, next, click on [EXIT]. 26.In the PREFERENCES dialog (1st icon, 2nd row), select a suitable image size (up to 320x200) and a quality factor you prefer. For quick results, select values like 80x80,TEST. Make sure to enable the CLOUDS checkbox and to set a valid path for the SHADER output files. 27.Next, select a surface definition for the floor. Click on the SURFACE icon (2nd icon, 3rd row). Choose LOAD and find & load the GRANITE.ISF file. Click inside the PATTERN box and change the direction to [Z]. Exit via [ OK ]. Now, click inside the BUMP MAP box and select [DENTS], then [ OK ]. Set the REFLECTION parameter in both columns to: 40 and leave the surface dialog. 28.Save your scene with the SAVE AS... option in the FILE menu. 29.Select SINGLE FRAME from the SHADER menu and click on [ OK ] to start the raytracing process. 30.After InShape computed the image, use the InShape Converter to convert the picture and display it with such file and image viewers like GEM-View.
