QUICK TOUR

Quick Tour is designed as examples to help you use 3DProS quickly. Run 3DProS, choose File->Open and browse to Example directory
Tutorials: Show you some features of 3DProS
Intermediate: Show you how to develop applications by using MathScript language
Advance: Show you how to develop applications by using FreePascal and MinGW C++





I. Using Object


1. Creating Object

Click the shape you want to create on the toolbar.





2. Selecting Objects

Click the object in the ListBox to select it.
Hold Ctrl or Shift if you want select multi objects
Select all objects by choosing Edit ( Select All





3. Editing Objects

You can copy, cut, paste objects by right-click on the form and choose appropriate command





4. Modifying Objects

You can modify properties of each object by using the Object Inspector on the bottom left corner.





5. Finding properties of each object

Select the object you want to find information
Click icon
on the toolbar, a window will appear to show you all properties of this object.








II. Features


1. Using Texture

You can place bitmap on object’s surface by using Texture property.
The Texture property specifies the filename of the bitmap in Texture directory.






2. Translating, Rotating and Scaling object

You can translate, rotate, scale object by using panel on the right corner (or modifying properties : Tx, Ty, Tz, Rx, Ry, Rz, Rz, Sx, Sy, Sz in the Object Inspector)






3. Drawing functions

3DProS support many custom functions

Z = F(X,Y) ; Y = F(X) ; R = F(T); …
First create function by clicking icon on the toolbar, then specify its expression by using Expression property in the Object Inspector










4. Rotating 2D objects

You can easily rotating 2D objects by using Status2D property
Status2D = (None, RotateX, RotateY, SetWidth, Box)














5. Mesh objects

- 3DProS supports mesh objects (.X files) and it also allows you to add your custom mesh objects.










6. Zoom in, Zoom out, Viewpoint

You can change viewpoint by choosing View(Look To, and you can also zoom in, zoom out the scene by choosing View(Zoom In, Zoom Out





III. Creating custom controls


1. Creating by dragging and dropping

Select all objects you want to combine
Choose AutoCreate icon
on the toolbar
Set name and group of the new object and click OK
An icon representing this object will soon appear on the toolbar
Place a bitmap file on the Bitmap directory if you want to give it a symbol











2. Creating by programming

Choose Shape ( Create
Provide information and default settings
Then you must give some code to tell the program how to draw this object, click Refresh to execute
If you have any comments, place it in the Info section
You can also inherit from existing objects by selecting Inherit From >>
Choose Save & Exit to save object.

This example illustrates how to create a line of sphere







3. Editing existing objects

Choose Shape( Edit Shape
A window will appear, select the object and the command you want to perform








IV. Programming and using functions


1. Programming

This example illustrates how to find central point
Create two points; name them p0, p1
Add this code fragment to the code window
Click icon
or choose Project(Run to execute






This example illustrates how to find symmetric points
Create some of points
Add this code fragment to the code window
Click icon
or choose Project(Run to execute









2. Using functions

This example will show you how to use function
Create three points, select them
Click
icon on the toolbar
A window will appear to
