TGorillaTerrainTexture

The terrain texture is a collection item with properties to configure rendering in the TGorillaTerrainMaterial shader.

Remarks

Because the shader renders specific textures on specific heights and handles smooth transitions between those, we need to have configuration possibilities.

Methods

public constructor Create ( ACollection : TCollection ) ;

Properties

published MinHeight : Single
Get or set the minimum height this texture is going to be rendered. The shader will consider the low-transition value to allow texture overlays.
read FMinHeight
write FMinHeight
published MaxHeight : Single
Get or set the maximum height this texture is going to be rendered. The shader will consider the high-transition value to allow texture overlays.
read FMaxHeight
write FMaxHeight
published LowTransition : Single
Get or set the lower transition ratio value. The larger this value is, the larger the texture transition area will get.
read FLowTransition
write FLowTransition
published HighTransition : Single
Get or set the upper transition ratio value. The larger this value is, the larger the texture transition area will get.
read FHighTransition
write FHighTransition

TGorillaTerrainMaterialSource

The terrain material source provides a shader for rendering textures from a pool of sources depending on the vertex y-position.

Remarks

Add multiple TGorillaTerrainBitmap instance to the bitmap pool by calling Bitmaps.Add() as TGorillaTerrainBitmap. You can then configure the min and max y-position, the low and high transition value and a tiling.
