3D graphics components and/or library for Delphi

I am looking for a mathematical or graphical library that provides Delphi components or function enabling creation of 3D graphics in Delphi.
Practically, I have a large set of x,y,z data that I need to 'plot' in 3D.
If the library includes tools to 'smooth' the result, it would be nice

hi again,

you may find some librarys at

examine also there the graphics-menu (there is more)

meikl ;-)
You will not find any related library or component in delphi!

But there is a lot of libraries for C. you can find a dozen of theme here:

3D Modeling:

3D Rendering:

there is a project name Quakk II. it is converted project of quack popular 3D game from original C code. search in sourceforge and you will find it! take a look at it, too!

Hi LeTay,

There are good news and bad news. Bead one: I was searching for a 'beefy' commercial library for 2 years (price was not important) - seems there is no such thing in Delphi like 'commercial+professional 3D library'. Good news TeeChart Pro from Steema.com is available for ~$100. It includes 3D and 3D_OpenGL. Also very easy to use - practically no code. TeeChart (standart version) is also included in Delphi (see Additional Tab). You may check first if it support 3D (sorry - I can not do this since TCPro installation overrides the standard TC).

Now questions: 1. now large is your data set?  2. is this regular x,y rgid (like a matrix 100x100 points each having Z value)? Or this is a set of (x,y,z) points (like geological data)? 3. How fast do you want to plot them. Do you want real-time data (rotation/zooming)? 4. Do you want 'closed' surface (example: thorus) or you want map-like?
5. Do you want top-view only (map) or all X, Y, Z axes visible?

The unswer which way to go depends on those 1-5 questions. Since I checked many of the libraries I can, probably,  suggest the right one. NONE of the libs I know can accomplish all 1-5. Sorry - graphic support in Delphi rather poor.

If your requirements are simple 2D grid I can, probably, provide some free code (do not expect it to be short :).

>graphic support in Delphi rather poor.

this i would not say
-> see the game age of wonders
Hi kretzschmar,

I know. But seeng the graphic program always 2 time slower than a similar written in C++ is depressing.
I have no clue why I still do it in Delphi?

odissey1 I thinkit is not true. both Delphi and C++ for 3D Drawing use of some libraries like OpenGL or DirectX.

The Speed of Rendering depend to speed for DirectX and OpenGL not to a programming languages.

Dear Odissey1
In a first stage, the data may just be x,z (without y) and so a simple 2D curve.
Number of points in one sample may be I think between 10.000 and 100.000.
It is "regular" in x-axis (x1,x2,... delta x the same), but it is geological-like : the z contains noise that needs to be eliminated (smoothed)
Off-line run so no problem of speed in theory
If axis y comes in the story, probably only a few y values. (so let's say 10 sets of sample x,z for 10 regular values of y) Closed surface view welcome in this case
Hi LeTay,

From your post it seems that TeeChart (TChart) is Ok for you.

Again, there are 2 approaches exist (the difference is speed). The data either could be presented as matrix
x&z are equidistant, so data look like
1 1 1 2 3 1
1 1 2 2 5 8
1 0 0 1 2 1
1 1 1 1 0 0
0 0 0 1 1 2

or ALL (x,y,z) point sets are irregular like
(1,1,0)  (2,5,1)  (7,4,0)  (7,6,6)  (1,1,0) ....

No library supports partially-regular data (X-regular, Z-irregular). So you must consider your data as 'irregular grid'.

Actually, the TChart covers both. It is not very fast with huge arrays (3D array of 1000x1000 will take ~5 sec to plot) You may download demo program from:


exe-demo with all features:

Trial versions:

Free trial version works while IDE. Price with academic discount ~$120.


with TCart, you simply add 3D series  to Chart via TC Editor and then iterate through your data:

procedure TForm1.Button1Click();

or for i:=0 to 1000 do

And thats All!
This may be good starting point. Ask Q if any.
