TTriSurface hardware accelaration

[Gabriel, A. TAOUSSI]

Hello,

I'm trying to represent a real-time curving substrate in 3D.
My goal is to offload most of the heavy-lifting onto a GPU.
To do so, I have put together a TTriSurface in a TChart within a demo project you'll find attached.
The rendering speed of my demo application is improvable (maximum 20 FPS on my machine).

How can I ensure effective hardware acceleration ?

Below are some items that stood out to me :
- In VCLTee, the OpenGL module achieves my requirements, but it isn't supported in FMXTee.
- Enabling global Skia4Delphi usage, TChart canvases seem to default to GLCanvas (supposedly an OpenGL canvas). Nevertheless, it doesn't seem to use the GPU out of the box.
- The base TChart canvas (D2DCanvas) doesn't seem to offload 3D rendering onto the GPU.

Below is my configuration:
Software:
- Embarcadero Delphi 11.3 version 28.0.48361.3236.
- TeeChart FMX Pro with source : Build 2023.38.230607.
- Skia4Delphi version 5.0.0.

Hardware :
- Intel Iris Xe graphics GPU (vPro i7 laptop CPU)
- Nvidia T550 Laptop GPU


Thanks in advance for your help.

Have a nice day.

Regards,

Gabriel A. TAOUSSI

Greetings,

To demonstrate the performance I'm looking for, please find attached a project based on VCLTee I have assembled :

I believe FMXTee's Chart3D holds the answer to my question. It does seem to support hardware acceleration out of the box.
Unfortunately, within a Chart3D, trisurfaces don't render at all on my machine.
In the attachments, you'll find another project to illustrate this, here is its output on my machine :

Any idea what I might be missing ?

Have a great day.

Hello Gabriel,

Sorry for the delayed reply here.

This is just to confirm only these environments use the GPU:
- VCL + OpenGL
- FMX + TChart3D

We are still experimenting with Skia canvas.

Unfortunately, within a Chart3D, trisurfaces don't render at all on my machine.

We'll take a look at that.
