Detailed Description

Image texture.

A TextureImage is a 2D texture based on a rt::image. \((0.0, 0.0, 0.0)\) is the top-left corner of the image, \((1.0, 1.0, 0.0)\) the bottom-right corner.

Constructor & Destructor Documentation

◆ ImageTexture()

rt::ImageTexture::ImageTexture ( rt::image * img )

Construct a texture from a pointer to a rt::image.

If the pointer is null, the black color will always be returned.

Member Function Documentation

◆ image()

rt::image * rt::ImageTexture::image ( ) const

The image of the texture.

May be null.

◆ setImage()

void rt::ImageTexture::setImage ( rt::image * img )

Set the image of the texture.

If the pointer is null, the black color will always be returned.

◆ value()

color rt::ImageTexture::value ( const vector & v ) const

virtual

Get the value/color of the texture.

Parameters

pos	A position in texture space. Because it is a 2D texture, the z component of the vector is ignored.
