| + | 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. | ||
| + | |||
| + | ^Format^Description^ | ||
| + | |TGorillaTextureKind.Texture2D|Default texture kind creating a two dimensional image.| | ||
| + | |TGorillaTextureKind.Texture3D|Creating a three dimensional texture.| | ||
| + | |TGorillaTextureKind.CubeMap|Creating a texture with 6 sides of 2D Images.| | ||
| + | ===== 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. | ||
