TeeChart V8 OpenGL vs. DirectX

Werner · Post by **Werner** » Fri Apr 04, 2008 3:38 pm

I have developed an application with TChart VCL V8 with TSurfaceSeries with
about 1 million datapoints. So the rotate function with vcl version is very slow.
I have added the teeopengl. The speed is good , but there was some bugs in teeopengl (missing clipping, zooming problems)

So my question:
Is directx supported ? And if, DirectX9 or DirectX10 ?
I have seen that TChart AX supports directx, is this available for delphi ?

How is the speed of TChart AX compare to VCL+OpenGL ?
Has TChart AX the same funtionality as TChart VCL ?

with best regards
Werner

Hi Werner,

>> Is directx supported ? And if, DirectX9 or DirectX10 ?
No, directx is not supported.

>>I have seen that TChart AX supports directx, is this available for delphi ?
I'm sorry, I'm not sure how you will use the TeeChart ActiveX components with directx, we've not done anything special to support directx on our activeX components.
About Delphi, the TeeChart Pro ActiveX version can be used into the Delphi IDE as standard ocx, but having the specific VCL version available, we do not offer support or this matter.

>>How is the speed of TChart AX compare to VCL+OpenGL ?
It should be the same.

>>Has TChart AX the same funtionality as TChart VCL ?
Yes, most of the functionalities (features) are the same. You can download and install both and check the demo features project in order to see all functionalities included.
