| + | ===== 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. | ||
| + | ===== Example ===== | ||
| + | |||
| + | At first a simple example where a TGorillaTextureBitmap is created with a size of 1024 x 1024 pixels and will all necessary settings. | ||
| <file pascal> | <file pascal> | ||
| Line 63: | Line 80: | ||
| finally | finally | ||
| LTexture.EndSetup(); | LTexture.EndSetup(); | ||
| + | end; | ||
| + | </ | ||
| + | |||
| + | Secondly a common example to ignore linear interpolation of a material texture. This becomes very useful, when displaying textures in pixelart, like minecraft. | ||
| + | |||
| + | We have to disable interpolation and mipmapping. | ||
| + | |||
| + | <file pascal> | ||
| + | var LTexture : TGorillaTextureBitmap; | ||
| + | begin | ||
| + | // request the texture and convert to Gorilla3D texture bitmap. | ||
| + | LTexture := GorillaLambertMaterialSource1.Texture as TGorillaTextureBitmap; | ||
| + | | ||
| + | // start manipulating properties and update them in GPU. | ||
| + | LTexture.BeginSetup(); | ||
| + | try | ||
| + | LTexture.MinFilter := TTextureFilter.Nearest; | ||
| + | LTexture.MagFilter := TTextureFilter.Nearest; | ||
| + | LTexture.Style := LTexture.Style - [TTextureStyle.MipMaps]; | ||
| + | finally | ||
| + | LTexture.EndSetup(); | ||
| + | end; | ||
| + | | ||
| + | // re-assign texture to update for shader | ||
| + | GorillaLambertMaterialSource1.Texture := LTexture; | ||
| end; | end; | ||
