C# Class Nez.Textures.TextureUtils

various utilties for creating textures on the fly. These can be pretty heavy on the CPU so it's best to not try to use them every frame.

Méthode Description
createBlurredGrayscaleTexture ( Microsoft.Xna.Framework.Color srcData, int width, int height, double deviation = 1 ) : Microsoft.Xna.Framework.Color[]
createBlurredGrayscaleTexture ( Microsoft.Xna.Framework.Graphics.Texture2D image, double deviation = 1 ) : Microsoft.Xna.Framework.Graphics.Texture2D

creates a new texture that is a gaussian blurred version of the original in grayscale
createBlurredTexture ( Microsoft.Xna.Framework.Color srcData, int width, int height, double deviation = 1 ) : Microsoft.Xna.Framework.Color[]
createBlurredTexture ( Microsoft.Xna.Framework.Graphics.Texture2D image, double deviation = 1 ) : Microsoft.Xna.Framework.Graphics.Texture2D

creates a new texture that is a gaussian blurred version of the original
createFlatHeightmap ( Microsoft.Xna.Framework.Color srcData, Microsoft.Xna.Framework.Color opaqueColor, Microsoft.Xna.Framework.Color transparentColor ) : Microsoft.Xna.Framework.Color[]
createFlatHeightmap ( Microsoft.Xna.Framework.Graphics.Texture2D image, Microsoft.Xna.Framework.Color opaqueColor, Microsoft.Xna.Framework.Color transparentColor ) : Microsoft.Xna.Framework.Graphics.Texture2D

processes each pixel of the passed in Texture and in the output texture transparent pixels will be transparentColor and opaque pixels will be opaqueColor. This is useful for creating normal maps for rim lighting by applying a grayscale blur then using createNormalMap* by doing something like the following. The first step is used only for making rim lighting normal maps: - var maskTex = createFlatHeightmap( tex, Color.White, Color.Black ) - var blurredTex = createBlurredGrayscaleTexture( maskTex, 1 ) - createNormalMap( blurredTex, 50f )
createNormalMap ( Microsoft.Xna.Framework.Color srcData, EdgeDetectionFilter filter, int width, int height, float normalStrength = 1f, bool invertX = false, bool invertY = false ) : Microsoft.Xna.Framework.Color[]
createNormalMap ( Microsoft.Xna.Framework.Graphics.Texture2D image, EdgeDetectionFilter filter, float normalStrength = 1f, bool invertX = false, bool invertY = false ) : Microsoft.Xna.Framework.Graphics.Texture2D

generates a normal map from a height map calculating it with a sobel filter
