Gorilla3D extends FMX texture support of TTextureBitmap. With default FMX behaviour you're only allowed to create a RGBA texture. | Gorilla3D extends FMX texture support of TTextureBitmap. With default FMX behaviour you're only allowed to create a RGBA texture. | ||
+ | ===== Texture-Kinds ===== | ||
+ | |||
+ | With v0.8.2+ more texture types than 2D textures are supported. | ||

===== Supported Formats ===== | ===== Supported Formats ===== | ||
+ | A texture format is described by a components internal format and a general format. While the components define the exact datatypes of byte data, the general format is more a simple setup information. | ||

+ | ===== Setting up ===== | ||
+ | |||
+ | To set up a Gorilla3D texture correctly, you need to encapsulate property configuration inside of BeginSetup and EndSetup method. | ||
+ | Only then all settings will correctly be submitted to OpenGL. | ||
