Let's make the following trees which consist of four panels from TATARA.
Press a cylinder first and make the form of a panel.
Make it into the structure with which four panels were vertically located in a line as follows.
And pile up four panels as follows.
And set the thickness of the joint of a panel and a panel as zero.
Then, the form where four panels using the full screen overlapped is made.
Rotate three panels. Although it is 1 prim, it becomes the tree made from 4 panels.
Furthermore, let's make the tree which is not influenced by LOD.
The step which makes a tree is as follows.
1) Press a pillar in TOKOROTEN mode and make a panel.
2) Make the 1st panel in ROKURO mode.
3) Copy the 1st panel in Bitmap mode and make the three remaining panels.
4) Adjust the bottom control point in ROKURO mode.
5) Choose the panel on 1st in Bitmap mode, and make it rotate in TSUCHI mode.
6) Choose the 2nd panel in Bitmap mode and make it rotate in TSUCHI mode.
7) Choose the 3rd panel in Bitmap mode and make it rotate in TSUCHI mode.
8) Make the texture used with the created sculpted prim.
9) Upload to an in world.
* 5)-7) steps are the same work.
If you master how to make this panel, you can make 2 Prim's tree combining a trunk.
Start TATARA and choose New-Sphere-16x64 of the File menu.
In order to edit the form where it is hard to be influenced by LOD, set Level of Detail on the View menu to Far.
Control points other than the control point used as a key are rearranged automatically.
Choose a TOKOROTEN tab.
In order to choose "41", click the ">" button at the lower left of an edit display. 41 sections are easy to edit.
Check that the display of the button at the lower left of an edit display is "41." And move the control point of the upper bottom in the center, respectively.
Other control points are rearranged automatically and you can get the following panels.
A preview is as follows.
Choose a ROKURO tab and make the top panel.
Move the top control point to an upper end.
As shown in the following figure, move a blue control point to an upper right end.
As shown in the following figure, move a purple control point to a lower right end.
As shown in the following figure, move a blue control point in the center of a lower end.
As shown in the following figure, move a red control point in the center of an upper end.
You can get the first panel now.
You can repeat this work and can make other three panels. But another method is explained. Let's copy the three remaining sheets with a Bitmap tab.
Choose a Bitmap tab.
Choose 00-G7 as follows and press the shortcut key of CTRL+C.
Then, the selected range is memorized by TATARA.
As shown in the following figure, the 2nd 08 is chosen from the left. Don't choose 08 of a left end! Since the right-and-left end is connected, you have to do in this way.
Press the shortcut key of CTRL+V.
Then, the coordinates of the control point were copied as follows and the copied control point will be chosen.
And choose the 2nd 00 from the left immediately under the control point chosen as shown in the following figure, and press the shortcut key of CTRL+V. The copied control point will be chosen.
Furthermore, choose the 2nd 08 from the left immediately under the control point chosen as shown in the following figure, and press the shortcut key of CTRL+V.
Four panels were made now. But the bottom control point is not arranged correctly.
Choose a ROKURO tab.
Move the control point of the bottom in the central lower part to an upper end.
It changed into the state where four panels overlapped as follows.
Let's rotate three of them.
Since four sheets have overlapped completely, you cannot choose a control point except a Bitmap tab. Therefore, choose a Bitmap tab.
Choose 00-G5 which does not contain the portion of the joint of the first panel as shown in the following figures.
Click a TSUCHI tab, in order to rotate this panel.
Click the XY button in the lower left of an edit display.
The following drafts are prepared in order to rotate a panel per 45 degrees. Please use this image.
Choose Load Background on the View menu and read against the background of this picture.
when the image is read, it will be displayed on an edit display as follows.
Since the angle to rotate is known, it is convenient. If such drafts are used, work will progress.
Since only one panel is chosen now, make the position which overlaps with a draft rotate this.
Drag a mouse, if cursor changes to a rotational form.
It is as follows.
Click a Bitmap tab.
Choose 08-GD. This is the 2nd panel from a top.
Choose a TSUCHI tab.
Rotate the 2nd selected panel 90 degrees. Drag a mouse, if cursor changes to a rotational form.
It is as follows.
Choose a Bitmap tab.
Choose 00-G5. This is the 3rd panel from top.
Choose a TSUCHI tab.
As shown in the following figure, rotate 45 degrees of 3rd selected panels counterclockwise. Drag a mouse, if cursor changes to a rotational form.
Then, a preview is displayed as follows.
Check whether Level of Detail on the View menu is set to Near, and also nearby it is displayed correctly.
You can check not changing.
Save a sculptmap file by Save on the File menu.
Please check the size of a sculptmap file by Setup. Please set TGA Size to 64x64.
Next, let's make the texture of the tree of the size of 512x1024.
Make the texture of the following tree of 512x512. Make a background transparent.
And as shown in the following figures, a texture is resized to 512x1024.
Since an up-and-down transparent portion is arranged at the top and the bottom of a panel, the edge of the upper and lower sides of a panel becomes transparent.
Then, let's upload to an in world.
When you upload a sculptmap file, be sure to use Upload Image of the File menu.
And check by preview and check Use lossless compression.
Let's also upload a texture.
And apply a sculptmap file to an object and set Horizontal of Repeats Per Face to 2.0 by setup of a texture. It is because a tree is displayed on the table and the reverse side of a panel, respectively. Although there were four panels, the transparent area of the texture was reduced by displaying a tree also on the joint of the portion which is not visible.
And set Horizontal of Offset to 0.5 and set Horizontal Vertical of Offset to 0.25.
A tree was completed.
