Detailed Description

Texture.

Textures are object holding a set of data, that can be accessed within a shader using a set of coordinates. Textures classes derives from Texture, which define a base implementation without specifying the texture dimensionality.

Texture can be one dimensional (Texture1d), two dimensional (Texture2d), three dimensional (Texture3d), cube mapped (TextureCube).

Property Documentation

bool Derm.Render.Texture.HasMipmaps [get, set]

Flag indicating whether this Texture has mipmaps definition.

This flag specify whether this Texture has mipmaps, or not. By

int Derm.Render.Texture.InternalFormat [get, set, protected]

Texture internal format.

Depending on the pixel data format, a default internal format is determined. It's possible to force the internal format by setting this property to a correct value. To default the internal format assign 0 to this property.

Magnification filter property.

Filter Derm.Render.Texture.MinFilter [get, set]

Minification filter property.

Pixel.Type Derm.Render.Texture.PixelFormat [get, set, protected]

Texture source pixel format.

int Derm.Render.Texture.TextelDataType [get, protected]

Texture data type.

int Derm.Render.Texture.TextelFormat [get, protected]

Texture data format.

Wrap Derm.Render.Texture.WrapCoordS [get, set]

Wrapping on texture S coordinate.

Wrap Derm.Render.Texture.WrapCoordT [get, set]

Wrapping on texture T coordinate.
