FMX.LowLevel3D Sample
This sample illustrates basic usage of low level 3D objects in mobile applications, using FireMonkey.
Contents
Location
You can find the FireMonkeyMobile LowLevel3D sample project at:
- Start | Programs | Embarcadero RAD Studio Athens | Samples and navigate to:
Object Pascal\Multi-Device Samples\User Interface\LowLevel3DCPP\Multi-Device Samples\User Interface\LowLevel3D
- Subversion Repository:
- You can find Delphi and C++ code samples in GitHub Repositories. Search by name into the samples repositories according to your RAD Studio version.
Description
This application defines a new Material using two predefined bitmaps and a random color. The new material is used to render a rotating rectangular shape within the 3D context of the application form.
How to Use the Sample
- Navigate to the one of the locations given above, and open:
- Delphi: LowLevel3D.dproj
- C++: LowLevel3D.cbproj
- Press F9 or choose Run > Run.
Notice the animated rectangular shape with the customized material.
Classes
- TForm1 represents the main window of the sample. It contains the following:
- two TBitmapObject objects used to set the two bitmaps used to create the new material.
- a TTimer used to create the animated rotation.
- TMyMaterial class defines the new material.
Implementation
- The new material is defined using low-level classes to manage graphical shaders: TContextShaderSource, TShaderManager, TContextShaderVariable. The rectangular shape and the new material are created on the OnRender event of the form.
- The drawing process is made through the TContext3D, associated to the TForm.
Uses
- FMX.Materials.TCustomMaterial
- FMX.Types3D.TShaderManager
